Scenarios for offshore wind development in the Netherlands: An agent-based modelling approach
No full textThe aim of this study is to develop a method to identify the barriers to and opportunities in the development of large-scale offshore wind energy in the Netherlands, taking into account the uncertainties of the future and consequences of decisions, from technological, economical, social, political and environmental perspectives. The research question is stated as: can an agent-based model be used to develop realistic implementation paths towards 6000 MW installed offshore wind power in the Dutch EEZ that show the consequences for the stakeholders? The focus topics for the model are the permit procedures, financial support, layout and timing of an offshore grid, the availability of resources, and innovation, especially of wind turbines. The results show that the agent-based model can indeed simulate different implementation paths that can be used for policy and decision support as a communication tool to show different possible futures and the limiting factors for the implementation in these futures. The methodology given in this study provides a step plan to develop such an agent-based model in analysis, design, implementation and validation phases. The main disadvantages of using agent-based modelling are: the extensive (detailed) data gathering, a long development time dependent on the implementation process and available standards, the required 'mass' and development time before simulations can be made that can be validated, and the limitations in modelling complex actor behaviour. The main advantages of using agent-based modelling are: the model can combine technological and socio-institutional aspects, the model can combine qualitative and quantitative data, the agent-based `as-is' modelling makes design easier, the model is easily extendable and a computer model is transparent.Wind EnergyAerospace Engineerin

Estimation of the circulation distribution on a rotor blade from detailed near wake velocities
No full textThe circulation distribution over a blade of a wind turbine model is estimated by use of a vortex model, which is matched with measured wake properties. With near wake velocities and the Biot-Savart law an optimization scheme is constructed to estimate the circulation distribution over the blade using a polynomial function series to approximate the circulation distribution. The velocities resulting from the calculated distribution are compared with the measured data, and deviations are discussed and explained. The vortex model offers insight into how the measured velocities can be separated into induced velocities of the different parts of the vortex system, such as the influence of the tip vortex. The sensitivity of the vortex model to its most uncertain parameters is tested. Finally the circulation distribution obtained with the vortex model is compared with the circulation distribution obtained through application of a blade element momentum (BEM) code. The BEM results show an underestimation of the circulation near the root and an overestimation of the circulation near the tip with respect to the vortex model results.

Navigating Risk to Resilience: Examining the impact of water risks on the investment decision-making process in polder-area development projects in the Netherlands
No full textIn the coming years, the Netherlands is expected to face various climate change-related challenges. Until 2030, the Dutch government has set the goal for the development of nearly a million dwellings (De Jonge, 2022), whereby 600,000 dwellings are being carried out in areas prone to flooding (Deltares, Bosch Slabbers, & Sweco, 2021; Groenemeijer & van der Lelij, 2021). In literature, work has been done regarding the current use of adaptation pathways, policies and their impact on decision-makers and practitioners (Restemeyer, van den Brink, & Woltjer, 2017; van Alphen, Haasnoot, & Diermanse, 2022; Yousefpour & Hanewinkel, 2016). However, limited efforts have been made regarding their practicality in the real estate sector. This research seeks to address the fundamental question, “who pays what, when?”. At its core, this research revolves around the influence of climate risks on the investment decision-making process in polder-area developments in the Netherlands and examines the research question: “In which way do water risks impact the investment decision-making process in polder-area development projects in the Netherlands?”. In this qualitative study, the urban area development projects Westergouwe (Gouda) and Gnephoek (Alphen aan den Rijn) are compared and analyzed. With the use of explorative interviews, and semi-structured in-depth interviews, the research strived to answer the research question. Afterward, an expert panel is held to bridge the gap to standard practice. This research found that the integration of adaptive measures into the investment decision-making process is currently insufficient. There is a need for clear policy, clear distribution of responsibilities and prioritization of water safety over financial considerations in the investment decision-making process. By navigating this complexity, driven by collaborative efforts, a holistic approach becomes imperative to forge a path toward a more resilient built environment.Architecture, Urbanism and Building Sciences | Management in the Built Environmen
Formalisation, then what?: Exploring the impacts of the process on recipient households in Albania
No full textThis thesis examines the impact of the formalisation process on recipient households in peri-urban areas of Albania, by employing a multi-dimensional framework, adapted from Frediani and Hansen (2015), which uses aspects of both the Capability Space and the Sustainable Livelihoods Framework. The main research question explores the impact of formalization on recipient households, while sub-questions delve into aspects such as tenure security, socio-economic characteristics, asset accumulation, and the influence of external factors on the benefits of formalization. It adopts a case-study approach, where different qualitative methods are used to study two cases in different cities in Albania, Kamëz and Durrës. A total of 36 recipient households were selected as participants, taking part in a qualitative door-to-door survey, where subsequently, five of which were part of semi-structured interviews. Alongside this, several experts and government officials were interviewed as well, to gain a better understanding of the issues and to assure the triangulation of the data. The data analysis utilized Excel for the survey data and ATLAS.ti for interview transcripts, employing both deductive and inductive coding techniques. The findings reveal that the obtaining of ownership certificates had limited overall impact on the access to livelihood assets amongst recipient households. While there were some enhancements in financial capital for a few participants, the changes were not present in the rest of the sample population. Moreover, for those few participants that observed any changes following formalisation, the possession of other assets and skills prior to the process, played a significant role in their ability to capitalise on the legal status of their properties. This thesis highlights the importance of considering multiple dimensions of well-being, and accounting for the local socio-economic contexts, to fully understand the impact of formalisation on recipient households. It emphasizes the need for further research into gentrification and formalisation, the need for longitudinal and comparative studies, as well as further academic research into policy measures that can address the broader socio-economic challenges concerning formalisation. Lastly, the findings can inform future initiatives aimed at promoting sustainable development and inclusive urbanisation in Albania and similar contexts.Architecture, Urbanism and Building Sciences | Management in the Built Environmen
Implementation of a new homeownership program in Jakarta: The case of zero down-payment housing program
No full textGovernments worldwide deal with the question of how to elevate their low-income household (LIH) into a higher standard of living. The main view of scholars on housing is that homeownership usually is the first step into improving the lives of people with a low income. The Province of Jakarta struggled with the same question. To address the housing challenge in Jakarta, they created the Zero Down-Payment Housing Program (ZDPHP) in 2017. This program's main purpose is to provide financing facilities to meet the basic need for adequate housing, targeting the LIH. However, the adaptation of this program has been slow, begging the question of what could be done to attract more beneficiaries. This article is intended to help improve the ZDPHP in Jakarta and give a perspective for other places thinking about implementing the same program. It explores the current eligibility criteria from the perspective of two out of five elements of the "5 As of Adequate Housing", Affordability and Accessibility, to understand the underlying housing challenge. Indicators of those two elements were collected from the data associated with the project. These data sources were supported and further explained using empirical data from policies analysis, interviews, FGDs, surveys and other existing databases. The most important findings were found as follows. Firstly, the best proportion of housing expenses to household income is to look at the actual comparison between household income and what a household pays for housing and transportation in its respective city. Secondly, to further strengthen the housing planning in Jakarta, an education program should be enforced alongside the ZDPHP. Lastly, with the recent launch of regulation regarding government land use permits, it is hoped that this will be a key solution to overcome land limitations and reduce house prices to become more accessible and affordable.Architecture, Urbanism and Building Sciences | Management in the Built Environmen
Land value capture as a method to involve private developers in placemaking projects
No full textRedevelopment of inner-city areas is a complex process involving multiple stakeholders, extensive timelines, and a variety of governance structures and financial mechanisms. The public party is primarily responsible for the quality of public space in the Netherlands. However, the municipalities face increasing financial challenges while private developers gain more land and thus more benefits from a high quality public space. To create those high quality and attractive places, placemaking can be introduced in the area redevelopment. It can be temporary and strategically applied to increase the attractiveness of the area, which results in increased private real estate values while it is publicly funded or subsidized. If private developers engage in placemaking, municipal spending can be reduced and the expenses and benefits of placemaking can be more evenly distributed. Therefore, this research examined a type of financing method, called ‘land value capture’, that might be utilized to engage private developers in placemaking projects. The research question that is addressed is as follows: To what extent can land value capture be applied in governance of area redevelopment to involve private developers in placemaking projects in the Netherlands?Architecture, Urbanism and Building Sciences | Management in the Built Environmen
How public green space is valued by residents of high-rise buildings in Rotterdam: A quantitative research to investigate the relation between public green spaces and the housing price of high-rise buildings in Rotterdam
No full textThis research investigated the determinant effect of public green spaces (PGS) on high-rise housing prices in Rotterdam. The growing population and tendency of people to gravitate towards city centers, have led to an increase in high-rise residential buildings in The Netherlands. It is therefore of high importance to optimize the integration of these buildings within its surroundings to increase the liveability, an important aspect of this is PGS. The gap in literature and social problems showed that there is a current mismatch with the desired and current needs of PGS regarding residents of high-rise buildings. The importance of PGS for residents of high-rise buildings is reflected by the housing price. The housing price indicates how much residents are willing to pay for certain variable of PGS and was used to evaluate different variables of PGS. The variables of PGS are divided into five domains: the environmental, social, cultural, functional and safety domain. Each of the domains indirectly affects the liveability of residents and citizens. The domains are identified by a comparison between international studies and Dutch municipal vision documents. The identified variables of the domains are further analyzed by a quantitative research, performed by a hedonic pricing model (HPM). Within this HPM, nine high-rise buildings were selected in the city of Rotterdam that provided an input of 977 apartments for the HPM. The regression showed a generally positive determinant effect of PGS on the housing price for high-rise buildings in Rotterdam. The strongest effect is the presence of having a PGS within 300m from the apartment, which impacts the housing price with a maximum of 17.7%. The view effects included in the HPM show a positive effect for both the number of green views and the specific PGS. The effects of the other PGS domains are correlated with the distance and view variables which makes it complex to quantify the effects of these domains separately. Interviews with developers of high-rise buildings, Stichting Hoogbouw and the municipality of Rotterdam were conducted to validate the results of the regression analysis and to assess the variables and aspects that are more difficult to objectively measure, such as the attractiveness of PGS. The main take-away of this research is that PGS have a positive determinant effect on the housing price of high-rise buildings which emphasizes the importance of having PGS nearby high-rise buildings. This study could be used as part of a reference approach for marketing research or during approval sessions regarding investment decisions to make stronger argumentations to implement PGS in the surrounding of high-rise buildings.Architecture, Urbanism and Building Sciences | Management in the Built Environmen
