This concept has continued to gain positive traction as a potential solution to achieve sustainable development. The circular economy (CE) increases waste minimisation by keeping materials and resources in a closed loop. The industry has been criticised for activities and processes that generate high volumes of waste, whilst obstructing sustainable development goal (SDGs) targets. The construction industry plays an essential role in a country's economic growth. This is seen as an important first step in influencing policy makers and repositioning resource efficiency firmly on the sustainable and carbon neutral building agenda. A proposition for extending research and its application to the built environment is then put forward, encapsulated in a conceptual model. It reviews literature on the CE and industrial ecology, their application to industrial and urban contexts, and the gaps pertaining to the building sector. Insight is offered into how this field of research might be developed and applied to enable a more resource-efficient, low-carbon built environment with socioeconomic benefits. Their application to cities and, in particular, the built environment has been limited and the body of literature is relatively undeveloped. Thus far, application of CE principles has largely concentrated on the industrial sector, such as through industrial symbiosis and its extension to urban symbiosis/metabolism. In this regard, the circular economy (CE) concept seeks to extract more value from resources by using them for as long as possible, thereby increasing economic prosperity and employment while reducing waste, greenhouse emissions, and pollution. ![]() Accordingly, this article seeks to highlight the importance of a resource-efficient built environment, which enables required functions to be delivered with less assets, and to put forward an approach toward this objective. In the near future further research on transparent ownership distribution between end-users and investors, ownership sharing with or distribution to suppliers of building parts and the further development of BIM solutions to easily trace materials and products in buildings are needed to extricate and enjoy the benefits of Circular Buildings.Īmid continued growth in the building stock, the pursuit of sustainable buildings is dominated by a focus on carbon neutrality and green, often overlooking resource consumption and its contribution to greenhouse gas emissions and planetary degradation. Further industrialization of the building approach in The Netherlands – especially in the Fit-Out – should create a further end-of-life value rise due to a more controlled high quality implementation approach. ![]() This can become a large factor in the protection remaining value of used items in buildings. Recent implementation of Open Building principles in national legislation in Japan and South Korea show an easier access to materials and products by partial disassembly due to separation of service systems from construction and façade elements. Open Building principles are effective as the basic connection between circularity and economy in those developments because it fundamentally incorporates the end-users interests. A difference of two years rent so.ĭue to the recent challenges of financial institutions, the power of public and private investors, developers and corporations has shifted towards more bottom-up end-user initiated Real Estate development. This is quite a change compared to the current estimates of one year rental costs for the final loop. Recent building value assessments approved by accountancy and banking officers in The Netherlands show a present value of materials and products at around a one years lease price of the project office space. Previous and expected future commodity price rises due to increasing demands and shortening supply of a large number of materials and products, introduce value creating options in buildings on the long run. So-far the investor, end-user and municipality were economically the deciding value driven partners of Real Estate, with the first being dominant decisive. The concept of Circular Economy introduces material and product after-use value as an increasingly important factor and a new economic factor of Open Building principles implementation in the Netherlands, Europe and possibly beyond.
