Effective strategy making: Co-designing scenarios as a tool for effective strategic planning
Get PDFFor establishing main lines of their future development, governments on several levels of government prepare spatial development visions, for assessing individual plans and initiatives against the background of a desired direction of development. Such strategic visions help to avoid the necessity to start considering again and again the question which direction long-term development should take. The European Commission promotes making such development strategies, hoping this leads to innovation in the regions and increased competitiveness of Europe. More particularly, the Commission expects a substantial contribution to prosperity of the rich diversity of local characteristics as assets for the development and innovation of the European territory.
This study aims to explore the factors for success of strategic spatial planning.
Strategy making happens in the different circumstances in European countries, legally regulated or informally, using terms like: Structure plans, structural visions, master plans, development visions and spatial development strategies. Here the term (spatial) development vision is used.
The central question is: Which aspects of planning processes and place-related conditions support the effectiveness of strategy making?
The processes of strategy making and the place related circumstances are intensively interrelated. The diversity of circumstances in the European countries is expressed in the different national and regional planning cultures. That includes the set of procedures, competencies, education of planners and other experts and their resulting attitudes towards strategy making. In a development strategy all interests of society come together. Therefore the constructive working together of representatives of different sectors and interest is key to the success. Because of this crucial issue, we distinguished between co-operation, as just contributing to someone else’s activity, co-producing, as making together a product and collaboration towards a strategy, defined as a common exploration of possibilities. The interactions of the participants in the strategy making process, potentially creating trust and enhancing social cohesion, may be more important than the resulting concept for a development strategy. Therefore our attention focused on the way strategies are made in the black box of specific processes. The interactions aiming at co-ownership and collaboration are central in this novel ’interactions approach’.
The resulting strategy does not necessarily contain (infra) structural projects; a spatial strategy concerns a selected localised policy and argumentative framework for future development.
Societal relevance
Being a planning consultant with over forty years of experience in practice, the author highly values practical applicability in society. Understanding of practice-related factors for effectiveness of strategy making is important because effective public management saves costs for society; a framework expressing the aimed-for direction of development provides clarity for private initiatives; an agreed strategy helps to coordinate sector policies; several EU and national subsidies for projects require a locally agreed structural frame.
Because a development vision concerns the direction of an envisaged development, its effectiveness is defined in terms of performance of the argumentative framework based on the story lines developed in the discussions during the strategy making process. Our search aims at identifying recommendations for enhanced chances for performing strategies in praxis.
Approach
A theoretical frame was composed based on literature in the fields of planning theory, policy analysis and design. Research questions were formulated concerning the importance of the process related variables: open process management, coownership, co-design, the application of scenarios and visualizations. Concerning the importance of the place related aspects, research questions consider: planning culture, multi-level embedding, involvement of politicians and the experiences of actors in previous processes.
The explorations for composing the theoretic frame aimed to do justice as much as possible to the complexity of network society in which a strategy has to be agreed. First (im-) possibilities for governing public administrations in network societies are explored. That exploration concluded that since the authority of data, experts and politicians are not self-evident anymore; there is a greater need than before that actors become convinced by arguments. Not interests as they see it (differently) but story lines support converging to an agreed selection of located objectives. Strategy making should therefore be organized as a societal process aimed at sharing ownership of ideas among participants.
The second exploration for composing the theoretic frame considered conceiving a development strategy as a decision-making process. The interdependencies of social, economic, ecologic and man-made physical systems in a territory require integrated decision-making involving the relevant interests. Acknowledging that the representatives of different sectors and non-governmental and private organizations foster different views on reality, implies that the specific procedures of spatial planning will generally not be accepted by all, as the procedure for the strategy making process. That entails decision-making occurring in a non-envisaged number of rounds of decision-making in different groupings. The ultimate success of a long-term development policy consists of flexible but continued application of the argumentative frame of the strategic vision. Fairly assessing long-term strategies requires evaluation, often decades after deciding on the strategy. Society seldom allows that time for assessing the success of a strategy because different urgent issues developed since it’s making and the vision became a “historic” view in the eyes of many. Therefore a different approach for establishing expected success was needed.
The specific, pivotal round of deciding about the concept of a strategic vision is called here effective, if the agreed strategy as resulting from that round of decision-making is expected to eventually perform. But effectiveness of decision-making is not sufficient; an effective strategy also implies a new promising perspective for the development of a territory. Effective decision-making consisting of effective continuation of an existing trend or more efficiently deciding on a concept does not need a strategic development vision. Those activities are not considered here for effective strategy making.
Therefore, the third exploration for composing our strategic frame focused on creativity as a requirement for discovering a novel direction of development. Discovering new possibilities for developments and re-interpreting existing qualities for new applications require an open creative approach. Design is needed for expanding the possibilities of what society sees as a probable future and above all for avoiding that the search for innovation would be restricted to what important actors consider possible. Central is the search for agreement about a desired future and how to make it possible. A process of co-designing a new vision of the desired future, whereby participating actors become co-authors of something not-existing before is assumed to bring about stronger and longer lasting commitment, which is essential for the long-term success. The assumed larger commitment would result from the combination of a maximal open process of decision-making like in designing, in which ideas of every participant are welcomed as valuable contributions and which takes the freedom of not starting by accepting limitations and conditions as coming from several sides. Such creative process is expected entailing forms of co-authorship. Important is that the relevant higher government level approaches the process positively and supportive, although without unconditional commitment to any outcome of the process. The empiric part contains case studies of five strategy making processes in different European countries.
The selection of cases was based on a pre-selection proposed by planners, representing their countries in the European Council of Spatial Planners (ECTP-CEU) They responded to the request for good examples of cases of successful strategy making in their countries. The final selection of five was chosen applying practical considerations about expectations of local help in assembling information. The selected cases were: Piano Strutturale Comunale of Bologna (IT), Scenariostudie Drechtsteden 2030 (NL), the Glasgow and the Clyde Valley Strategic Development Plan (UK), Vision Gherdí«ina (IT) and Meetjesland 2020 (BE). Next to plan documents and existing evaluations, forty-one interviews formed important sources of information for connecting casuistic and theory. Applying our definition of effectiveness, first the effectiveness of our cases was established. Not all of those five appeared to be effective according to our criteria as formulated in the theoretical frame. Next the cases were analysed, using pre-formulated hypotheses for process and place-related conditions influencing the performance of spatial development strategies. The accounts of cases in different planning cultures related to the process and place-aspects of the theoretic frame provided insight in the different process aspects and the circumstances in which those processes were conducted. That, in combination with the earlier established (non-) effectiveness enabled characterizing the processes within their various administrative and societal environments. Subsequently the process aspects and the place-related aspects of the five cases were compared and analysed applying the research questions, the hypotheses and the chains of evidence. Such comparison allowed for conclusions about factors for effectiveness.
Conclusions
The study did not provide evidence that strictly regulated, rigid planning cultures were prohibitive for strategy making. In all five processes a form of co-production existed, which in most cases resulted in some form of co-ownership of the results. Co-ownership evaporated soon in the cases that were not qualified as effective. Remaining co-ownership appeared to be most important for the eventual success of the spatial development vision. That has been established in Drechtsteden, Glasgow and Grãdental (Vision Gherdí«ina). The strategy making in Bologna and Meetjesland was not successful. In Bologna lack of success resulted from extensive procedural requirements, political instability and the complexity of the administrative embedding, despite a strong concept for future development. In Meetjesland the failure was related to the lack of a sound administrative embedding together with insufficient specificity of the vision: a set of nine objectives without concrete elaborations and selective site locations did not build lasting support. The study confirmed that effective decision-making processes for long-term developments are open, interactive collaborations towards new concepts applying visualizations (maps) and the related storylines of representatives of the interests that are considered relevant locally.
Although the selection of cases consisted of processes, which were found successful by planners of the country in which the cases are located, two of the cases were not effective according to our criteria. Not only satisfaction about the initial result and a form of co-ownership was important, the continuation of the processes in subsequent rounds of decision-making was even more important. The openness of decisionmaking is of special importance for converging to an agreement. Introduction of a design attitude in strategy making, applying maximal openness results in creating coauthorship, which entails stronger, lasting commitment to the agreed vision. Here the specific attitude is not meant of some, who concentrate on conditions and on mapping the limitations set by what important actors see as possible or feasible as a starting point. That approach tends to design in the limited space left over by other sector’s claims. Designing as meant in the current study regards the open “what if, then that” iterations during which designers focus on exploring new possibilities, not respecting conditions and limitations in advance. Preparing a spatial development strategy as a societal decision-making process by applying an open design attitude implies generating ideas, assessing, correcting, improving and refining solutions.
The study confirmed the importance of visualizations as tools for enhancing the effectiveness of communication during the collaborative process. In order to open up minds for different ways of viewing during the process and to do justice and pay respect to ideas of the participants, decision-making is preferably organized as scenario planning, considering simultaneously several options and in which every tabled idea is considered and assessed according to its potentials, (im)possibilities and consequences.
Discovering new possibilities together and co-designing a desired future entails co-authorship, which goes beyond and enhances co-ownership. This also applies for the administrative embedding: in two of the three successful cases the higher level authority acted as co-authoring partner of the development vision. Important for such vertical commitment is that the number of administrative layers with which the strategy making process must relate, should be small: preferably only one higher authority. In such cases, the strategy making process will not become an arena in which several higher authorities conduct their institutional policies for fighting their struggles for hierarchy. The only (approving) authority can support the process according to its commitment and act as a partner. Acknowledging that the responsibilities of a higher authority do not allow full commitment in advance to a yet unknown output, applying a form of loose coupling is helpful. This implies that the higher authority supports the process and commits to positively considering consequences of the output, provided that specific process conditions are fulfilled. This especially applies if envisaged large infra structural projects require substantial investments of higher authorities.
The study confirms the importance of involving spatial designers and a design attitude in the collaborative decision-making process towards long-term development strategies. The necessary openness of such processes requires conducting designing not as a person-focused internal activity but to design as a process of group creativity in the collaboration of relevant participants. The ‘interactions approach’ provided useful conclusions and contributes as a novel to existing planning theory
Performative Microforests: Investigating the potential benefits of integrating spatial vegetation environments into buildings, in regards to the performance of buildings, their occupants + local ecosystems
Get PDFThe design of office buildings can substantially improve the building, social, and ecological performance of office building projects. However, existing research on improving the performance of work environments has primarily focused on identifying and evaluating methods to make work environments less bad, rather than focusing on how to develop work environments that are positively performing. Moreover, the potential of building projects to perform positively, in terms of economic, social, and ecological performance, remains relatively unexplored in existing research and building projects. To this end, this PhD research project is focused on exploring the positive economic, social, and ecological performance potential of buildings. Specifically, this research project identifies and evaluates the potential economic, social, and ecological performance benefits of integrating microforests into office buildings.Microforests are defined in this book as dynamic, stimulating, cohesive spatial environments that are composed of vegetation and soil layers that mimic the structural, perceptual, and ecological composition of a forest ecosystem, yet are not large enough to reliably provide the myriad of functions of a robust, mature forest ecosystem. This design research focus is based on findings from existing literature that suggest that natural environments and stimuli can provide a diverse range of economic, social, and ecological performance benefits.The Design Research Methodology [DRM], an established research methodology that facilitates the use of diverse research methods in a rigorous, effective manner, is used in this research project to explore and evaluate the performance potential of microforests, by investigating the following sub research questions:
How can microforests improve the performance of office buildings?
How can microforests improve employee performance + comfort?
How can microforests improve the ecological performance of office buildings?
Within the DRM research framework, explorative design case studies, systematic literature reviews, expert interviews, observation case studies, and experimentation research methods were employed, in order to develop design guidelines, high performance space types and case studies, as well as assessments of the hypotheses of several experiments.For instance, as part of the investigation of the first sub research question, a design case study was conducted that evaluated the potential of microforests to reduce the energy consumption rates of office buildings, both in terms of the potential of vegetation to function as a shading device, and in terms of the potential energy savings that can be attained through the provision of semi-outdoor, high quality microforest workspaces. The results of this study, which are discussed in Chapter 4, indicate that vegetation can be as effective, or more effective, than typical shading devices, in terms of shading effectiveness. Moreover, in terms of economic performance, this study found that improving occupant work performance provided substantially greater economic benefits than reducing the energy costs of the mid-size commercial office building. This finding indicates that, in terms of economic performance, design teams should be focused on designing office environments that improve worker performance. Thus, the results of this case study indicate that economic and worker performance are interrelated.In order to investigate the potential effects of microforests on occupant thermal comfort, a quasi-experiment which evaluated the potential psychological and physiological impacts of microforests on occupant thermal comfort, was conducted. This study is discussed in Chapter 5. The results of this study indicate that working within a densely vegetated work environment, such as a microforest, improves occupant thermal comfort, both in normal and more extreme temperatures, throughout the four seasons. Thus, the inhabitation of microforests can improve occupant thermal comfort, as well as reduce building energy consumption rates, by allowing the temperature set point of the space to be raised in the summer and lowered in the winter.In terms of microforests impacting worker performance, a multidisciplinary, systematic literature review was conducted to identify the potential of the design of work environments to impact worker performance, particularly natural environments such as microforests. The results of this review, which are discussed in Chapter 6, indicate that natural environments can provide a diverse range of worker performance benefits. However, further research is necessary to determine the effectiveness of various design solutions, space types, and space qualities on worker performance. To this end, a survey was conducted to evaluate the types of work environments and space qualities that promote worker performance, including constructed and natural environments, in terms of a diverse range of work tasks. The results of this study, which are described in Chapter 7, suggest that knowledge workers prefer to conduct a wider variety of work tasks in microforests, compared to a range of existing work space types, than existing research suggests. Moreover, the results of this study suggest that different types of microforests, such as spatially open and public microforests compared to more dense and private microforests, provide different performance benefits, and are preferred for different work tasks. Hence, these findings suggest that the integration of microforests into office buildings can improve worker performance, and from a more general perspective, that workers prefer to have access to more diverse types of work spaces within their office environment than typical office environments provide. Furthermore, the results of the conducted studies indicate that the design of work space environments, at both the scale of individual spaces and space qualities, impacts worker performance, and thereby should be accounted for in the design of office environments.In terms of microforests impacting the ecological performance of building projects, a systematic literature review was conducted to investigate the ecological performance potential of building projects. The results of this review are presented in Chapters 8-11. Three general design strategies to improve the ecological integrity of local ecosystems were identified: design for ecosystem functions, design for ecological behavior, and design for biodiversity. The potential effectiveness of various design strategies within these three general design strategies were explored, as well as gaps in existing research, and issues with evaluating the ecological performance of building projects. Potentially effective design solutions were identified, such as hybrid infrastructure, gene seed banks, and constructed environments which are designed to foster positive experiences in natural environments.Moreover, the results of this review indicate that further research is needed to evaluate the comparative value of different ecological design solutions, as well as effective means to account for the interrelationships of building projects with their local and regional contexts.Taken together, the results of this research project make it evident that the design of constructed environments has a significant impact on the performance and value of building projects, from economic, social, and ecological performance perspectives. More specifically, the integration of microforests into office environments was found to yield a diverse range of building, worker, and ecological performance benefits. The results of this research project can aid in the development of comprehensive design support systems and building project performance metric systems, as well as identify, and in some cases evaluate, potentially high performing, innovative design solutions and strategies. However, it is important to note that the results of this research project indicate that, in order to develop comprehensive building performance evaluation metric systems and design methods, further research is necessary. To this end, this research project identified innovative performance benefits that the design of building projects, and microforests, can provide, as well as identified existing research gaps that should be addressed. This research project also identified potentially high performing space types and design strategies, including various types of microforests.In summary, the results of this research project demonstrate that the design of building projects can be an effective and efficient method to generate diverse economic, social, and ecological performance benefits. Moreover, the results of this research project suggest that the design of high quality spaces, particularly microforests, can improve the social and ecological performance of building projects, while at the same time, also reduce building costs

Get PDFThe “third skin” of human beings — the building envelope — has a long history of development with a major impact on architecture. As an interface between inside and outside, facades not only determine aspects such as performance and energy efficiency, they also determine the aesthetics of buildings and cities; to the extend that they can create cultural identity. The invention of the curtain wall made facades independent from the building structure, but it remained an important — yet passive — element.

Composite hollow core vaults: An analysis of the Fusí©e Cí©ramic System and the design of form-active environmental friendly roofs
Get PDFJust after World-War II building materials were scarce, architects and engineers had to design buildings using not much cement and steel. In French an architect, Jacques Couí«lle, had invented a system with cí©ramique infill elements to reduce for structures of concrete the self-weight and need of cement and steel. In the fifties and sixties of the twentieth century these cí©ramique elements, known as Fusí©e Cí©ramique elements, were used widely in France, North Africa and the Netherlands, mostly for barrel vaults and shells. Nowadays most of these structures are pulled down and the remaining buildings do not meet the demands of the present concerning climate comfort, insulation and safety.
This thesis analyses the structural design of cylindrical Fusí©e Cí©ramique roofs in the context of those days. The effect of the cí©ramique infill elements for the time dependent deformations, stiffness and load bearing capacity, including second order, is studied. To save the few remaining buildings for the coming generations the possibilities to strengthen these structures with slender light elements of steel are explored. The effect of the strengthening is described for a Fusí©e Cí©ramique vault, designed and constructed in the past.
Reinforced concrete is a widely used building material with many advantages. Unfortunately the production of both reinforcement and cement is quite energy intensive and causes the emission of greenhouse gasses as NO2, NO and CO2. Reducing the need of cement is a relative simple way to reduce the emission of these greenhouse gasses.
In practice roofs are seldom really flat but curved or at least slightly inclined, to drain rainwater and snow. Structurally curved structures, transferring loads as a surface-active or form-active structural system, are very efficient. The need of material and the self-weight is pretty low. This can be very useful if in the future the potentials of roofs for producing food and energy are used more often and these roofs must be designed for much heavier payloads as usual at the present.
For form-active and surface-active roofs of concrete the self-weight and need of steel and cement can be reduced further with light infill elements. This study of the Fusí©e Cí©ramique system shows that infill elements can save cement, self-weight and reduce the environmental load. The possibilities to save cement and reduce the environmental load with infill elements are studied with respect to the construction techniques of the present.
The design of prefabricated cylindrical vaults, composed of segments following a part of a circle and strengthened with slender ties of steel to reduce the bending stresses, is described. To produce prefabricated cylindrical barrel vaults efficiently a positioning of tubes perpendicular to the span is preferable. The effect of this infill concerning the load transfer is analysed. Models of a prefabricated element, with tubes positioned perpendicular to the span, are tested to define the structural bearing capacity of prefabricated barrel vaults
From access to re-use: A user’s perspective on public sector information availability
Get PDFIf data are the building blocks to generate information needed to acquire knowledge and understanding, then geodata, i.e. data with a geographic component (geodata), are the building blocks for information vital for decision-making at all levels of government, for companies and for citizens. Governments collect geodata and create, develop and use geo-information - also referred to as spatial information - to carry out public tasks as almost all decision-making involves a geographic component, such as a location or demographic information. Geo-information is often considered “special” for technical, economic reasons and legal reasons. Geoinformation is considered special for technical reasons because geo-information is multi-dimensional, voluminous and often dynamic, and can be represented at multiple scales. Because of this complexity, geodata require specialised hardware, software, analysis tools and skills to collect, to process into information and to use geoinformation for analyses.
Geo-information is considered special for economic reasons because of the economic aspects, which sets it apart from other products. The fixed production costs to create geo-information are high, especially for large-scale geo-information, such as topographic data, whereas the variable costs of reproduction are low which do not increase with the number of copies produced. In addition, there are substantial sunk costs, which cannot be recovered from the market. As such, geo-information shows characteristics of a public good, i.e. a good that is non-rivalrous and non-excludable. However, to protect the high investments costs, re-use of geo-information may be limited by legal and/or technological means such as intellectual property rights and digital rights management. Thus, by making geo-information excludable, it becomes a club good, i.e. a non-rivalrous but excludable good. By claiming intellectual property rights, such as copyright and/or database rights, and restricting (re-)use through licences and licence fees, geo-information can be commercially exploited and used to recover some of the investment costs.
Geo-information is considered special for a number of legal reasons. First, as geo-information has a geographic component, e.g. a reference to a location, geoinformation may contain personal data, sensitive company data, environmentally sensitive data, or data that may pose a threat to the national security. Therefore, the dataset may have to be adapted, aggregated or anonymised before it can be made public. Secondly, geo-information may be subject to intellectual property rights. There may be a copyright on cartographic images or database rights on digital information. Such intellectual property rights may be claimed by third parties involved in the information chain, e.g. a private company supplying aerial photography to the National Mapping Authority. The data holder may also claim intellectual property rights to commercially exploit the dataset and recoup some of the vast investment costs made to produce the dataset. Lastly, there may be other (international) legislation or agreements that may either impede or promote publishing public sector information, whereby in some cases, these policies may contradict each other.
It has been recognised that to deal with national, regional and global challenges, it is essential that geo-information collected by one level of government or government organisation be shared between all levels of government via a so-called Spatial Data Infrastructure (SDI). The main principles governing SDIs are that data are collected once and (re-)used many times; that data should be easy to discover, access and use; and that data are harmonised so that it is possible to combine spatial data from different sources seamlessly. In line with the SDI governing principles, this dissertation considers accessibility of information to include all these aspects. Accessibility concerns not only access to data, i.e. to be able to view the data without being able to alter the contents but also re-use of data, i.e. to be able to download and/or invoke the data and to share data, including to be able to provide feedback and/or to provide input for co-generated information.
Accessibility to public sector geo-information is not only essential for effective and efficient government policy-making but is also associated with realising other ambitions. Examples of these ambitions are a more transparent and accountable government, more citizens’ participation in democratic processes, (co-)generation of solutions to societal problems, and to increase economic value due to companies creating innovative products and services with public sector information as a resource. Especially the latter ambition has been the subject of many international publications stressing the enormous potential economic value of re-use of public sector (geo-) information by companies. Previous research indicated that re-users of public sector information in Europe encountered barriers related to technical, organisational, legal and financial aspects, which was deemed to be the main reason why in Europe the number of value added products and services based on public service information were lagging compared to the United States. Especially the latter two barriers (restrictive licence conditions and high licence fees) were often cited to be the main barriers for reusers in Europe. However, in spite of considerable resources invested by governments to establish spatial data infrastructures, to facilitate data portals and to release public sector information as open data, i.e. without legal and financial restrictions, the expected surge of value added products based on public sector information has not quite eventuated to date and the expected benefits still appear to lag expectations.
When this research started a decade ago, the debate around accessibility of public sector information focussed on access policies. Access policies ranged from open access (data available with a minimum of legal restrictions and for no more than marginal dissemination costs) to full cost recovery, whereby all costs incurred in collection, creation, processing, maintenance and dissemination costs to be recoveredfrom the re-users. Most of the public sector bodies in the European Union adhered to a cost recovery policy for allowing re-use of public sector information. In 2003, the European Commission adopted two directives to ensure better accessibility of public sector information Directive 2003/4/EC of the European Parliament and of the Council of 28 January 2003 on public access to environmental information and repealing Council Directive 90/313/EEC, the so-called Access Directive, provided citizens the right of access to environmental information. Citizens should be able to access documents related to the environment via a register, preferably in an electronic form and if a copy of a document was requested, the charges must not exceed marginal dissemination costs. Directive 2003/98/EC of the European Parliament and of the Council of 17 November 2003 on the re-use of public sector information, the co-called PSI Directive, intended to create conditions for a level playing field for all re-users of public sector information. However, the PSI Directive of 2003 left room for public sector organisations to maintain a cost recovery regime with restrictive licence conditions. In spite of these directives, access policies for geographic data were slow to change in most European nations.
At the end of the last decade, accessibility of public sector information received two major impulses. The first major impulse was the implementation of Directive 2007/2/ EC of the European Parliament and of the Council of 14 March 2007 establishing an Infrastructure for Spatial Information in the European Community (INSPIRE), the cocalled INSPIRE Directive, established a framework of standardisation rules for the data and publishing via web services, which significantly contributed to the accessibility of public sector geo-information. The second major impulse was the development of open data policies following the Digital Agenda for Europe adopted in 2010 and the USA Open Government Directive of 2009 and the Digital Agenda for Europe of 2010. These two impulses were the main drivers in Europe to start a careful move from cost recovery policies to open access or open data policies and for more public sector information to be made available as open data. Thus, of the four barriers to re-use of public sector information data cited in Chapter 1 (legal, financial, technical and organisational barriers), two barriers should have been lifted to a large degree due to open data. This shift to open data provided an excellent opportunity to test the hypothesis that the main barriers for re-users of public sector information were indeed restrictive licences and high fees as suggested by earlier research.
Chapter 2 showed that by 2008, most European Union Member States had transposed and implemented the 2003/98/EC PSI Directive, however, in various ways and with considerable delay. By 2008, the effects of the PSI Directive were only slowly starting to emerge. A number of Member States reviewed their access policies and more public sector information became available for re-use. Some Member States made the information available free-of-charge or reduced their fees significantly. In many cases, where re-use fees were reduced the number of regular re-users increased significantly and total revenue even increased in spite of lower fees. Although the 2007/2/EC INSPIRE Directive paved the way for technical interoperability by providing guidelines for web services and catalogues, neither the INSPIRE Directive nor the PSI Directive had tackled the issue of legal interoperability. Chapter 2 also demonstrated that a major barrier to creating a level playing field for the private sector was the fact that some public sector bodies acted as value added resellers by developing and selling products and services based on their own data. Thus, the level playing field envisioned by the European Commission had not been realised.
Chapter 3 researched the aspect of harmonised licences as a first step towards legal interoperability. Earlier research had indicated that one of the biggest barriers for re-users were complex, intransparent and inconsistent licence conditions, especially for re-users wanting to combine data from multiple sources. A survey of licences used by public sector data providers in the Netherlands demonstrated that although there were differences in length and language, there were also many similarities. The conclusion was that the introduction of a licence suite inspired by the Creative Commons concept would be a step towards increased transparency and consistency of geo-information license agreements. This chapter introduced a conceptual model for such a geo-information licence suite, the so-called Geo Shared licences. Both Creative Commons and Geo Shared licence suites enable harmonisation of licence conditions and promote transparency and legal interoperability, especially when re-users combine data from different sources. The Geo Shared licence suite became a serious option for inclusion into the draft version of the INSPIRE Directive as an annex. Unfortunately, the concept of one licence suite for the entire European Union came too early in 2006. The Geo Shared licences were further developed and implemented into the Dutch National Geo Register.
In 2009, the European Commission recognised that PSI was the single largest source of information in Europe and the potential for re-use of PSI needed to be highlighted in the digital age. As part of a review of the 2003/98/EC PSI Directive, the European Commission carried out a round of consultations with stakeholders to seek their views on specific issues to be addressed in the future in 2010. In addition, the Commission commissioned a number of studies. These studies included a review of studies on public sector information re-use and related market studies, an assessment of the different models of supply and charging for public sector information and a study on public sector re-user in the cultural sector. The first study, carried out by Graham Vickery in 2011, showed that the overall economic gain from opening up public sector information as a resource for new products and services could be in the order of €40 billion per annum in the European Union. Both the Vickery Report and the second study, the so-called POPSIS Study, showed that for most public sector data providers their revenues from licence fees were relatively low in comparison to their total budget. After the evaluation, Directive 2013/37/EU of the European Parliament and of the Council of 26 June 2013 amending Directive 2003/98/EC on the re-use of public sector information was adopted and came into force on 17 July 2013. Chapter 4 described the main changes of the 2013/37/EU Amended PSI Directive, including the recommendation to employ open data licences. This chapter continued with a review of the various open data licences in use in Europe and analysed their interoperability. Although adoption of open data licences for public sector information should have addressed legal interoperability barriers for re-users, in practice, the different types of open data licences might not be so interoperable after all. Effectively, only a public domain declaration, such as a Creative Commons Zero (CC0) declaration, is suitable for open data re-users requiring with cross-border data sets and that such a public domain declaration is published in a prominent place to remove uncertainty for re-users. Without a public domain declaration, re-use of open data is still impeded as re-users are loathe to invest time into the development of value added products or services when it is uncertain if and which restrictions may be applicable and what the impact may be on their product or service.
This dissertation also researched the financial and economic aspects of public sector information accessibility. Chapters 1 and 2 indicated that a cost recovery regime for dissemination of public sector information provided a financial barrier for private sector re-users because the fees charged were perceived to be too high. However, in 2008, there were still many advocates for maintaining a cost recovery regime. Especially public sector bodies that are not funded by the national Treasury, the socalled self-funding agencies, needed revenue from data sales to cover a substantial part of their operational costs. A sustainable source of revenue was viewed as essential to maintain the data at an adequate level, and to ensure actuality and continuity. Chapter 5 explored the potential business models and pricing mechanisms for public sector INSPIRE web services. Although, depending on the type of web service, and type of re-user, there might have been an argument for employing a subscription model as a pricing mechanism, business models based on generating revenue from public sector information would not be viable in the long run and were not in the spirit of the INSPIRE Directive. This research concluded that public sector information web services employing different pricing regimes were counterproductive to achieving financial interoperability.
In Chapter 6, business models for public sector data providers were revisited, this time from an open data perspective. Government agencies, including self-funding government agencies are under increasing pressure to implement open data policies. This chapter analysed the business models of self-funding agencies either already providing open data or under pressure to provide (some) open data in the near future. The analysis showed which adaptions might be necessary to ensure the long-term availability of high quality open data and the long-term financial sustainability of self-funding agencies. The case studies confirmed that providing (raw) open data does not necessarily lead to losses in revenue in the long term as long as the organisation has enough flexibility to adapt its role in the information value chain, especially when revenue from licence fees represents only a relative small part of theirtotal budget. The case studies indicated that switching to open data has resulted in internal efficiency gains. In practice, it is difficult to isolate and quantify the internal efficiency gains that are solely attributable to open data as the researched organisations continuously implement efficiency measures. However, the reported decreases in internal and external transaction costs due to open data are in line with the case study carried out in Chapter 7.
Open data also provided an excellent opportunity to assess the effects of open data ex ante as baseline measurements could be carried out. To develop both quantitative and qualitative indicators to assess the success of a policy change is a challenge for open data initiatives. In Chapter 7, a model to assess the effects on the organisation of an open data provider was developed. Liander, a private energy network administrator mandated with a public task, planned to publish some of their datasets as open data in the autumn of 2013. This offered an excellent opportunity to apply the developed assessment model to provide an insight into internal, external, and relational effects on Liander. A benchmark was carried out prior to release of open data and a follow-up measurement one year later. The benchmark provided an insight into the then work processes and into the preparations required to implement open data. The follow-up monitor indicated that Liander open data are used by a wide range of users and have had a positive effect on the development of apps to aid energy savings. However, it remains a challenge to quantify the societal effects of such apps. The follow-up monitor also indicated that regular re-users of Liander data used the open data to improve existing applications and work processes rather than to create new products. The case study demonstrated that private energy companies could successfully release open data. The case study also showed that Liander served as a best-practice case for open data and had a flywheel effect on companies within the same sector. By 2015, nearly all energy network administrators had published similar open data. The monitoring model developed in this project was assessed to be suitable to monitor the open data effects on the organisation of the data provider.
The assessment model developed and tested in Chapter 7 proved to be suitable to monitor the effects of open data on organisational level. However, to provide a more complete picture of the effects of open data and to assess if there are other barriers for re-users, a more holistic approach was required to assess the maturity of open data. Therefore, a holistic open data assessment framework addressing the supplier side, the governance side, and the user side of the open data was developed and applied to the Dutch open data infrastructure in Chapter 8. This Holistic Open Data Maturity Assessment Framework was used to evaluate the State of the Open Data Nation in the Netherlands and to provide valuable information on (potential) bottlenecks. The framework showed that geographic data scored significantly better than other types of government data. The standardisation and implementation rules laid down by INSPIRE Directive framework appear to have been a catalyst for moving geographic data to a higher level of maturity. The maturity assessment framework provided Dutch policy makers with useful inputs for further development of the open data ecosystem and development of well-founded strategies that will ensure the full potential of open data will be reached. Since the publication of the State of the Open Data Nation in 2014, a number of the recommendations have already been implemented.
This dissertation demonstrated that many aspects that should facilitate accessibility, such as standardised metadata, have already been addressed for geodata. This research also showed that for other types of data, there is still a long way to go. There is a growing demand for other types of data, such as financial data and healthcare data. Public sector organisations holding such types of data need hands-on guidelines to enable publication of their datasets, preferably as open data. However, data published as open data are forever and cannot be recalled. Therefore, the decision to publish public sector data as open data is complex: datasets are often of a heterogeneous nature and may contain microdata (data that quantify observations or facts, such as data collected during surveys) Although microdata may not necessarily contain personal data, the datasets will probably have to be processed before publication to address confidentiality and data quality issues. In addition, there is a tension between open data and protection of personal data. The big question remains to which level the data need to be aggregated and/or anonymised to ensure protection of personal data now and in the future, and at the same time keeping sufficient significance to be re-usable. Another issue that needs further research is data-ownership of sensor data and co-created data. Increasingly, sensor data generated by e.g. smart phones, smart energy meters and traffic sensors are collected by the public sector and the private sector and become part of a big data ecosystem. In addition, public sector organisations cooperate with other public sector organisations and the private sector to create information from their data, so-called co-created information. Citizens also collect data or complement information on
Imagine: RAPIDS 2.0
No full textIn 2014, a 3D-printed Canal House by DUS architects caught the attention of the world — including President Obama. The 3D Print Canal House proved the potentials of Additive Manufacturing for architecture and construction. Additive Manufacturing provides the architect with completely new solutions for realising tool-less production methods while allowing maximum freedom of design. Additive Manufacturing is ideally suited for Rapid Prototyping. It is possible to manufacture physical presentation and functional prototypes with complex shapes quickly and cost-efficiently without the need for manual processing — directly using three-dimensional CAD construction data. This makes the entire product development process considerably faster.
Imagine 10 explores the potentials of Additive Manufacturing for architecture by charting the current state of technology, discussing its implications for design and construction processes, and presents research projects as well as concept ideas for future Additive Manufacturing applications
AM Envelope: The Potential of Additive Manufacturing for facade constructions
Get PDFThis dissertation shows the potential of Additive Manufacturing (AM) for the development of building envelopes: AM will change the way of designing facades, how we engineer and produce them. To achieve today’s demands from those future envelopes, we have to find new solutions.
New technologies offer one possible way to do so. They open new approaches in designing, producing and processing building construction and facades. Finding the one capable of having big impact is difficult — Additive Manufacturing is one possible answer.
The term ‘AM Envelope’ (Additive Manufacturing Envelope) describes the transfer of this technology to the building envelope. Additive Fabrication is a building block that aids in developing the building envelope from a mere space enclosure to a dynamic building envelope.
First beginnings of AM facade construction show up when dealing with relevant aspects like material consumption, mounting or part’s performance.
From those starting points several parts of an existing post-and-beam façade system were optimized, aiming toward the implementation of AM into the production chain. Enhancements on all different levels of production were achieved: storing, producing, mounting and performance.
AM offers the opportunity to manufacture facades ‘just in time’. It is no longer necessary to store or produce large numbers of parts in advance. Initial investment for tooling can be avoided, as design improvements can be realized within the dataset of the AM part. AM is based on ‘tool-less’ production, all parts can be further developed with every new generation.
Producing tool-less also allows for new shapes and functional parts in small batch sizes — down to batch size one. The parts performance can be re-interpreted based on the demands within the system, not based on the limitations of conventional manufacturing. AM offers new ways of materializing the physical part around its function. It leads toward customized and enhanced performance.
Advancements can for example be achieved in the semi-finished goods: more effective glueing of window frames can be supported by Snap-On fittings. Solving the most critical part of a free-form structure and allowing for a smart combination with the approved standards has a great potential, as well.
Next to those product oriented approaches toward future envelopes, this thesis provides the basic knowledge about AM technologies and AM materials.
The basic principle of AM opens a fascinating new world of engineering, no matter what applications can be found: to ‘design for function’ rather to ‘design for production’ turns our way of engineering of the last century upside down. A collection of AM applications therefore offers the outlook to our (built) future in combination with the acquired knowledge.
AM will never replace established production processes but rather complement them where this seems practical. AM is not the proverbial Swiss-army knife that can resolve all of today’s façade issues! But it is a tool that might be able to close another link in the ‘file-to-factory chain’. AM allows us a better, more precise and safer realization of today’s predominantly free designs that are based on the algorithms of the available software. With such extraordinary building projects, the digital production of neuralgic system components will become reality in the near future — today, an AM Envelope is close at hand. Still, ‘printing’ entire buildings lies in the far future; for a long time human skill and craftsmanship will be needed on the construction site combined with high-tech tools to translate the designers’ visions into reality. AM Envelope is one possible result of this
Stedenbouwkundige waardestelling van industrieel erfgoed
Get PDFThis dissertation is the reflection of the research study into urban planning structures of historic industrial complexes. The study’s aim has been to promote recognition and acknowledgement of these structures as the carriers of cultural-historical values in spatial transformation.
Apart from object value, industrial heritage also has ensemble value. Being “the field of study into the material culture remains of industrial production and technology”, the field of Industrial Archeology offers the opportunity to gain further knowledge of the nature and background of industrial spatial planning. Given the current focus on cultural- historical values in spatial planning and the fact that the strategy of ‘conservation through development’ has found widespread recognition and application, this dissertation has set out to arrive at concrete definitions and instrumentation of reuse and transformation in urban planning. The study is based on existing sources of knowledge which allowed two spheres of human involvement and endeavour to be connected. The first is building archeological research that has been put into operating guidelines and has developed into a considerable volume of knowledge and experience which has shaped the practice of planning as well as the teaching of design. This field of knowledge represents the cultural- historical component of the study. In addition there is the domain of spatial planning discipline. The knowledge acquired in this area has been brought together in a series of four publications under the heading “The Fundamentals of Urbanism in the Perspective of the Twenty-First Century”. This, too, incorporates a considerable volume of knowledge and experience, which has been been laid down in publications classified on the basis of a planning-level approach to distinguish aspects of design, theory, law and programming. This planning-level approach allows for a structured and differentiated way to tackle industrial urbanization at the level of its composing parts.
One case study lies at the heart of this dissertation’s research. It’s that of the former industrial estate of Philips Strijp-S at Eindhoven, The Netherlands. In selecting this location aspects of size and range have been taken into consideration. A decisive factor in its selection, no doubt, has been the amount of attention generated by and for the transformation itself. Prominent administrative and professional parties have gone through a process of research and planning that has been extensively documented. As a result, a fair account of the facts could be made. In it the administrative and societal contexts are closely connected with both research and design of the transformation. Urbanization archeological research is conducted under two denominators: research and value assessment. In order to reach a cultural-historical valuation, this study includes reference research into the city of Zlín, the cradle of Thomas Bat’a’s shoe industry in the former Czechoslovakia, for three reasons. There are major similarities between Philips and Bat’a in momentum, industrial ambition and innovative fundamental attitude first at the personal level of the entrepreneurs, secondly at the company level of industrialised production, and thirdly at the level of spatial and societal conditions.
Philips started as a light-bulb factory located at Emmasingel, now part of the city centre of Eindhoven. When the company expanded with the addition of its own glass factory, it marked the beginning of the Strijp-S industrial estate. The Strijp-S study continues to concentrate on the most important period in terms of urbanization history, from the start of construction at the site in 1916 up to the fifties. At that point the company’s expansion involved the outplacement of essential company parts. The year 1951 marks the completion of the Strijp-S era, because it was then when the company’s spatial situation was documented by means of an ‘enriched’ map of the factory’s industrial estate.
The ‘bottom-up’ approach of the Guidelines for Building Archeological Research (2009) has been adopted for the research study into the history of Strijp-S construction and use. The origin and expansion of the spatial planning structure of the Strijp-S estate have been shown in connection with the development of the company itself. The innovative fundamental attitude that led to the diversification of production (from light bulbs to a broad range of electrical appliances) in the first half of the twentieth century turned out to have been the breeding ground for an equally innovative architectural and urban-planning establishment of spatial and societal conditions in the interest of the company and the city of Eindhoven as a whole. Narrowly tracing the growth stages of the estate has brought into focus the elementary parts of the kind of spatial and programmatic structure which in the course of time have developed into typological constructs. Knowledge of Zlín and Bat’a helped to identify the factors that contributed to the success of the Philips company organization as inspired by American examples, such as Daylight Factories, Integrated Industry and Company Town. Thomas Bat’a built nearly a hundred daylight factories in and around Zlín, a city with a population of 40,000. Here the Integrated Industry did not only involve the production of shoes but also the ‘production’ of the entire city, in recent literature praised as a model company town. There was a substantial connection with Philips as appeared from the decision in the twenties to locate the Dutch branch of Bat’a in the town of Best, not far from Philips. In addition, an architectural-historical connection came to light between Zlín and Tony Garnier’s plan for a ‘Cití© Industrielle’, which he had already developed in 1904, but was not published until 1917 under the title Une Cití© Industrielle in reference to Lyon. Garnier’s spatial concept was virtually copied for Zlín. Although there is no irrefutable proof, a connection between Strijp-S and Garnier’s work is not unlikely in view of the personal connection between Anton Philips and Thomas Bat’a.
On the basis of existing knowledge of the Zlín reference case a value assessment has been made for Strijp-S. As an extension of the editorial part, a values map has been designed to serve as an instrument for the urban spatial developer. Much was to be gained from a cartographer’s point of view since existing maps are wide of the mark. Maps that seemed to fit into the framework of the archeological urban approach turned out to be focused on the object too much, to be of varying levels of abstraction and to be unsuitable as blueprints for development.
Elementary parts of the spatial and programmatic development of the urbanization of Strijp-S could be identified and inserted into the plannning-level structure of “The Fundamentals of Urbanism”. As a result a classification of concepts in the interest of cartografical representation was possible. The urbanization archeological values map that has been produced in this way has all the hallmarks that are needed for it to serve as a blueprint for the development process: topographical precision, abstract representation of spatial structures and distinguishing features according to cultural- historical values.
The transformation history of Strijp-S is characterized by a process in which urban- planning research has not always been connected to development in the proper chronological order. In a review of that process and the development plans that have been made for Strijp-S in recent years by means of the set of instruments developed, it has been found that there is much left to be desired about those plans in terms of the cultural-historical values of the industrial spatial planning of the estate
Understanding culture in territorial management and its implications for spatial planning
Get PDFPrevious experiences have shown that the implementation of planning policy does not always lead to the originally intended territorial management outcomes. This issueˬis particularly crucial when policy ideas, institutions, models and programmes are transferred into places with different cultural settings without adaptations (Knieling and Othengrafen 2009b; Sanyal 2005). These unexpected consequences in planning practice and management outcomes have brought a significant amount of attention to the importance and roles of culture on shaping decision-making in territorial management process and determining transferability of a policy (Friedmann 2005a, 2005b; de Jong and Mamadouh 2002; Sanyal 2005; Ostrom 2005a; Knieling and Othengrafen 2009b). However, conceptual frameworks that seek to understand the roles of culture and its implications for spatial planning are still rather limited.
This study presents and applies an integrative conceptual framework which is usedÀ¨to explain how culture, planning policy and territorial management outcomes are interrelated, and what the implications are for spatial planning. The framework integrates relevant theories and ideas from anthropology, organisational management and political sciences to understand influences of culture on spatial planning. The integrative framework suggests a way of characterising territorial management in the form of ideal types. This helps simplify cultures regarding territorial management to make them comparable. It enables an analysis of ‘cultures’ that includes a broader scope of culture than existing frameworks that focus primarily on ‘planning cultures’ expressed in forms of planning systems, organisations and instruments. This broader scope includes also the implicit expressions of culture in informal forms, such as ideas, customs and social behaviours shared by involved actors in the management of a given territory.
The framework also offers two analytical perspectives to investigate whether culture is an important element (or context variable) explaining planning practices and territorial management outcomes in different settings. These perspectives are the analysisˬthat assumes a stable state of culture (a synchronic perspective) and the analysis that considers culture as dynamic and interrelating with other context variables (a diachronic perspective). Findings derived from the analysis of the case studies based on these two perspectives help draw theoretical conclusions about how planners may deal with culture in order to improve planning practices.
The study investigates territorial development processes in the context of floodplain management in urbanised delta regions. This specific context is selected because of its strong relations between physical attributes and spatial planning activities. The analysis is carried out based on a comparative approach at two levels. At the cross-national level, the Rhine-Meuse delta region in the Netherlands and the Chaophraya delta region in Thailand are used as case studies. The comparative approach is useful for this study because culture can be best understood in a relative form. The sub- national analysis emphasises comparison of floodplain management in three selected districts in the Chaophraya delta region. The two levels of analysis are carried out in order to understand whether the influences of cultures on planning practices and territorial management outcomes at different scales of development are affected by similar elements. Besides the theoretical contribution, this study also contributes methodologically through development of a common conceptual framework that can be applied to the analysis of various issues in territorial management, which is not limited only to the subject studied here. The framework is also expected to be applicable for the analysis of territorial management in a diverse range of cultural settings.
The findings derived from a synchronic analytical approach validates arguments given by previous studies (such as de Jong and Mamadouh 2002 and Stead et al. 2008) regarding the importance of ‘conformity’ between policy content and local cultures for enhancing achievement of policy implementation and transfer. The findings from a diachronic perspective contribute to understanding of dynamic dimensions of culture as interrelating to other context variables. It reveals that cultures regarding floodplain management can be categorised into two parts — (i) the part that is significantly affected by core values and (ii) the experiential part of culture with close relationships with physical environments. Each dimension of culture regarding floodplain management is sensitive to each part of culture to different degrees. Furthermore, the analysis reveals two fundamental conditions required to promote effective management of collective tasks. They are (i) a unified perception towards shared problems and solutions; and (ii) management that acknowledges local institutions throughout planning process.
In short, the conceptual framework proposed in this study proves to be helpful in gaining a better understanding of culture regarding territorial management and its implications for spatial planning. The findings imply that despite the significant influences of cultural preconditions in shaping planning practices and territorial management outcomes, planners may use spatial intervention mechanisms to ensure that outcomes match initial policy objectives. This could be done through the promotion of caution and cultural sensitivity in policy design, and in selecting appropriate implementation mechanisms to match the local preconditions
Social Housing Organisations in England and The Netherlands: Between the State, Market and Community
Get PDFRapid and deep changes in society, the economy and policy over the last decades ˬare having an increasing impact on the delivery of social housing in North Western Europe. These changes are transforming the way in which social housing providers perform their task and are reshaping their relationships with the State, communities and with other market actors. The combination of continued State withdrawal from service provision, the deep and persistent effects of the global financial crisis that begun in 2008 and profound changes in the type of demand for social housing across North Western Europe call for a reflection on the implications of these phenomenaˬfor social housing providers. Several studies indicate that social housing providers in Europe have begun to adopt new (social) entrepreneurial strategies and are becoming more innovative as a response to these challenges. These strategies imply tackling the tensions between (at times) conflicting drivers, notably those arising from the State, the market and communities. However, research in this topic so far is fragmented, focussing on one country or on specific sub-areas such as asset management and non-housing activities and rarely connects with the relevant wider literature on the third sector and social enterprise.
Within this context, this PhD research has sought to widen this discussion by providing new insights through a comparative study of the ways in which individual social housing providers are relating to (i.e. responding to and influencing) these contextual changes. More specifically, the research sought to better understand the complex process of decision-making these companies undergo to manage their responses to competing drivers. Companies operating in two countries (England and The Netherlands) were studied in-depth. In both countries, the social rental sector has played a prominent role in their respective welfare states for decades. While both are amongst countries with the highest share of social rental housing in Europe, each represents a different type of welfare state and of social housing provision - following Kemeny’s classification, a unitary system (the Netherlands) and a dualist system (England).
