The concept of circular economy have gained a popularity in the scientific areas for the past decades due to raising influence of climate change, overpopulation, deforestation, resource depletion, urbanization, pollution and other global issues. Real estate is crucial aspect for every human being, because majority of people spend majority of their lifetime in buildings which are mainly located in cities. Purpose of the study is to reflect how built environment and real estate industry can benefit from the features of circular economy concept while promoting the practices of sustainable development. Authors have carried out a study based on the methodology of literature review and state of the art review to show how features of circular economy can support practices of sustainable construction. Results show that the construction processes can be supported by features of circular economy throughout the whole life cycle of construction project including logistics, supply chains, design, manufacturing process, exploitation and maintenance of real estate and reusing the building materials. Research indicates that urban circular economy contributes to the development of sustainable societies. Additionally, efficient implementation of circular construction requires profitability for majority of stakeholders.

The mounting climate change crisis and the rapid urbanization of cities have pressured many practitioners, policymakers, and even private investors to develop new policies, processes, and methods for achieving more sustainable construction methods. Buildings are considered to be among the main contributors to harmful environmental impacts, resource consumption, and waste generation. The concept of a circular economy (CE), also referred to as “circularity”, has gained a great deal of popularity in recent years. CE, in the context of the building industry, is based on the concept of sustainable construction, which calls for reducing negative environmental impacts while providing a healthier indoor environment and closing material loops. Both vernacular architecture design strategies and circular economy principles share many of the same core concepts. This paper aims at investigating circular economy principles in relation to vernacular architecture principles in the built environment. The study demonstrates how circular principles can be achieved through the use of vernacular construction techniques and using local building materials. This paper will focus on Egypt as one of the oldest civilizations in the world, with a wide vernacular heritage, exploring how circularity is rooted in old vernacular settlements and how it can inspire contemporary circular practices.

Current Trends

A growing concern is given to the environmental impacts caused by the construction industry. Waste generation, resource consumption, and greenhouse gas emissions are the main drawbacks of the rapid urbanization that the world is witnessing. As a response to these pressing issues, policymakers and academia are exploring the concept of Circular Economy (CE) to manage resources better and achieve resource efficiency while eliminating waste. One of the strategies to implement CE in the built environment is to select the appropriate building materials and components from the early stages to carry out the concept's principles along the value chain and create a closed-loop system. Therefore, this study aims at identifying selection criteria for building elements according to CE principles through a review of the latest research. Results have shown that little has been concretely achieved in terms of a paradigm shift to CE since the main focus of the literature is still the use of recycled products and the recyclability of building materials and components at their end-of-life. Although the present study is solely focused on the technical aspect of building materials and components, it outlines current adopted criteria to bring about a circular built environment and highlights the need for a more innovative approach to attain higher circularity levels.

Key Factor

The built environment requires ever-increasing amounts of raw material resources and at the same time bears the responsibility for the resulting waste. Waste is generated throughout the life cycle. In the initial phases it is referred to as industrial waste, while during construction, reconstruction, and demolition it is called construction waste. Construction waste is most voluminous but it also has a great potential in circular economy that aims at the closed loop cycle where already used construction materials and components are recovered as raw materials. Sustainable building principles include four basic strategies, waste avoidance, construction materials and components re-use, continued use, and recycling. The possibility of construction waste treatment and its possible recovery in the building process depends on the type of prevailing materials that are contained in building elements as well as on detachability, separability and inseparability of structural joints and components. The architect plays a responsible role in decreasing the volume of construction waste as the conception of a building represents the key factor in sustainable construction waste management. Planning a construction with a good dismantling potential at the end of the building’s life cycle includes a number of factors such as the choice of building materials with a low environmental impact, the design of detachable composite materials and structures as well as the design of mono material structures. This article focuses on waste resulting from the built environment and discusses architectural concepts with a potential of reducing the volume of construction waste and its potential recovery as a construction resource.

Intermediaries and standards in the real estate industry. The aim of the paper at hand is to examine the significance of the integration of financial and real estate markets for urban property markets. It is argued that the integration of both markets has increased the volatility of urban property markets and in particular of the office market of financial cities as London and Frankfurt am Main. International property consultants play a key role in it as knowledge brokers. Through their global office networks they produce and offer information about the outlook of investment possibilities, i.e. urban property markets. In that sense they channel capital which contributes to increased volatility of capital flows into and out of the built environment. Thus, the liberalisation and globalisation of the financial markets as well as modern investment products transformed the urban real estate markets to a great extent.

Abstract The objective of this review paper is to survey the state of the art on nature-based solutions (NBS) in the built environment, which can contribute to a circular economy (CE) and counter the negative impacts of urbanization through the provision of ecosystem services. NBS are discussed here at three different levels: (i) green building materials, including biocomposites with plant-based aggregates; (ii) green building systems, employed for the greening of buildings by incorporating vegetation in their envelope; and (iii) green building sites, emphasizing the value of vegetated open spaces and water-sensitive urban design. After introducing the central concepts of NBS and CE as they are manifested in the built environment, we examine the impacts of urban development and the historical use of materials, systems and sites which can offer solutions to these problems. In the central section of the paper we present a series of case studies illustrating the development and implementation of such solutions in recent years. Finally, in a brief critical analysis we look at the ecosystem services and disservices provided by NBS in the built environment, and examine the policy instruments which can be leveraged to promote them in the most effective manner – facilitating the future transition to fully circular cities.

Logistics real estate is a type of property rarely covered in the existing literature on the financialisation of property markets. The emergence of specialised international real estate firms, which act as developers, investors and property fund managers, means that the logistics real estate industry has taken a unique financialisation path. The present article explains the specific features of the financialisation of the logistics real estate industry and contributes to the understanding of the financialisation of outer-suburban governance. Based on a qualitative analysis of the European logistics real estate market and case studies conducted in the Greater Paris region, the article combines an analysis of the sociotechnical mediations of financial circuits in the logistics built environment with the study of emerging local public–private coalitions formed to develop logistics zones. As such, it will be seen that the domination of integrated global firms in logistics real estate depends on their capacity to form local coalitions.

Waste Minimisation

A circular economy requires closed circuits of consumed resources. Construction generates approximately 50% of solid waste globally, which is difficult to manage. The aim of this article was to identify the factors that determine the development of circular construction in the context of waste minimisation in the life cycle of building structures. The identification of cause-and-effect relationships by means of the DEMATEL method allows the problems of construction waste management to be taken into account in the context of the development of sustainable construction and fulfilling the principles of the circular economy.

Urban Heat

Emerging crises for resources and energy has became one of the major global issues. Unstoppable population and urban growth is demanding shelter. The figure for estimated housing shortage across the world according to the internationally recommended standards is 428,700,000 units. By the year 2030, an additional 3 billion people, about 40 percent of the world’s population, will need access to housing. This translates into a demand for 96,150 new affordable units every day and 4000 every hour.(United Nation –Habitate:2005)(128). All this unstoppable global population growth is resulting in high demand supply gap between resources and thus present trend concentrate to satisfy and minimize this gap. This shooting urbanization problem is leading towards diversion for easy and fast construction methodology.Along with this the problems associated to it are also increasing globally. The problem of Urban Heat Island and Urban Canyon Effect, CO2 emission , Green House Effect , Resource depletion and all such problems are demanding global attention to overcome it and make habitant sustainable for safeguarding future generations to come. The major hurdle for application of sustainable construction is barrier of human mind who concentrates more on initial cost of construction and negligence towards operations energy cost and pay back period calculations.The aim of the paper is to show feasibility of application of waste in construction elements like wall by analysing thermo resistive property of such waste filled cavity wall and equivalence cooling effect calculations for conventional clay brick wall , AC sheets , cavity wall and various waste filled cavity wall by making model and process of simulation using Ansys Fluent .The results of research work shows feasibility of adopting cavity wall and waste fill cavity wall for construction of wall because of its high thermoresistive property so as to mitigate global problems like Urban Heat Islands and operational energy consumption.
