Intelligent or smart cities and buildings: a critical exposition and a way forward
No full textIn the last decade, there has been an undoubtedly rising interest in the field of intelligent and smart built environments from design and construction to management, operational and governance perspectives. These recent endeavors, observed at both academic and professional levels, can be classified into city, neighborhood and building scales. In this context, understanding what we really mean by the word intelligent and smart is crucially important. This technical note attempts to clarify and further explore how intelligence differs from smartness in this context. Having intelligence as the main umbrella embracing other interrelated smart subsets is one way of thinking as supported by previous debates, while there are also other lines of thinking with more preference on the smartness as the core concept
What is an intelligent building? Analysis of recent interpretations from an international perspective
No full textIn recent years, the notion of intelligent buildings (IBs) has become increasingly popular due to their potentials for deploying design initiatives and emerging technologies towards maximized occupants’ comfort and well-being with sustainable design. However, various definitions, interpretations, and implications regarding the essence of IBs exist. Various key performance indicators of IBs have been proposed in different contexts. This study explores the notion of IBs and presents an analysis of their main constituents. Through a comparison of these constituents in different contexts, this study aims to extract the common features of IBs leading to an evolved definition which could be useful as a reference framework for design, evaluation, and development of future IBs. Findings also scrutinize the long run benefits of IBs, while demonstrating the constraints and challenges of the current international interpretations

Building facades: Issues of sustainability, maintenance and refurbishment (SUE-IDCOP)
No full textThe UK has a fairly mature building stock with between 1 and 5 % of new buildings being introduced each year. The development of new façade solutions which can respond to the needs of the occupants of both new and refurbished buildings is therefore a key area for development. The built environment is a major consumer of energy across the domestic, industrial and service sectors. The construction and operation of buildings are responsible for about one-third of the energy use and one-half of the electricity use in most industrialised countries. A large share of the energy use is associated with protection from the external climate and operation of systems necessary to give the occupants a comfortable indoor environment. Natural light is seen as a key driver to people’s well being both in the workplace and at a home. However, to realise high daylight factors in offices on overcast days in particular requires highly glazed facades. Single glazed windows result in high winter month heat loads, whereas modern double or triple glazed units could result in summer overheating without additional solar protection or ventilation. This paper discusses the issue of façade refurbishment or replacement in the UK for multi-occupancy buildings in both the commercial and domestic sectors. Sustainability is considered from people, process and product perspectives for traditionally glazed façades in comparison to double skin façades and climatic envelopes
Upskilling for technology enhanced collaborative working
No full textIntelligent buildings present a number of challenges. They must be responsive to people’s needs including their health and wellbeing; be sustainable in the use of resources as well as incorporating the most useful parts of the evolving technologies.
The Roadmap reviews these demands including the relationship of intelligent buildings to the infrastructures of towns and cities. The processes of planning, design, construction and facilities management are complex and require decision making that is clear but realises the strategic and tactical inputs required by all the stakeholders including the clients. Intelligent buildings are part of our history as well the future.
They are a distinguishing mark of civilisations worldwide. In the 21st century with increasing populations in cities buildings need to be places to work and live with pleasure and joy. Simple things like connecting with Nature give so much value. In the complex and high speed world we must not forget that simplicity has appeal to the human spirit besides being more durable in the long term.
This set of essays, which comprise the Roadmap written by members of the W098 Commission and CIBSE Intelligent Buildings Group opens the door to collective thought and ideas for now and the future
