“…On the other hand, academics understand that specific criteria from regulations can be an obstacle to the intervention in urban areas, which require improvements in the living conditions of a diverse range of inhabitants (Casals-Tres et al, 2013). They apply for the existing buildings' preservation instead of their demolition for the preservation of their features, materials, use, and function (Mària & Salvadó, 2017), as well as for adequate energy efficiency demands (Fuertes, 2017).…”

“…The need for energy efficiency follows the Urban Agenda for the European Union (European Commission, 2022), which highlights the need to reduce energy consumption and provide affordable housing (Ascione et al, 2022;Casquero-Modrego & Goñi-Modrego, 2019). Some studies criticize the fact that the stakeholders in charge of decision-making lack knowledge of the environmental (e.g., reuse the materials), economic, social, and cultural benefits of the reuse of cultural heritage buildings (Foster, 2020;Fuertes, 2017;Giuliani et al, 2021;Mària & Salvadó, 2017), neglecting the protection of urban heritage areas and their landscape, as recommended by UNESCO guidelines (UNESCO, 1972(UNESCO, , 2011.…”

Climate change, natural hazards, and human actions are threatening cultural heritage in urban areas. More than ever, building regulations’ procedures and criteria are essential to guarantee the protection and safeguarding of urban areas and their buildings. These procedures and criteria are crucial to assist stakeholders in decision-making, especially when facing rapid transitions and transformative changes in urban heritage areas. Several institutional stakeholders in charge of urban heritage protection strengthen the need for a better implementation of building regulations through flexible criteria to support intervention procedures in buildings with different features and in different contexts. Under this topic, the present study uses a twofold method. Firstly, the authors analyze and compare the urban and building regulations of three Southern European countries, Italy, Spain, and Portugal, concerning procedures and criteria directed to the built heritage; secondly, they highlight and compare the views of different institutional stakeholders from the same three countries, at different levels (national, regional, and municipal), to understand the impact of the implementation of the regulations on the ground. The findings show the relevance of the institutional stakeholders’ views to improve the regulations and their practice. They highlight the need to promote inventory and cataloging procedures, as well as flexible criteria when dealing with urban heritage buildings.

“…However, the defined methodology could be combined with other experimental assessment procedures, to be applied in the preliminary phase as a guide in the choice of a new use for abandoned buildings [87,88], and furthermore, this approach allows a quantification of the environmental profile of the built environment, promoting its reuse according to its real hidden environmental potential [89].…”

The abandonment of the built heritage, as a result of functional or technological obsolescence or as a consequence of cultural, social, and economic trends, is steadily increasing. This great number of buildings, worldwide spread, offers a huge opportunity to reduce the environmental impacts related to the construction industry. Nonetheless, the recovery and reuse interventions that require the implementation of residual technological performance, to accommodate new uses, are not always environmentally neutral. Therefore, a new design approach needs to be developed so as to improve the buildings’ technological performance and enhance resources and energy already incorporated in buildings. The circular economy principles in the building sector, performance-based building design together with downcycling and upcycling theories are applied to develop a methodology aiming to reduce the environmental impacts within the rehabilitation and refurbishment design process. Starting from the building analysis phase (historical, material, construction) residual performance is evaluated; then the design phase demonstrates that, according to downcycling and upcycling design strategies applied on building components and materials, it is possible improving the building to the required new uses while minimizing transformations and effectively reducing related environmental impacts. The reduction of environmental impacts depends on a careful assessment of the residual technological and structural performance that the building still provides, by involving limited performance implementations to balance rehabilitation needs and environmental protection goals.

“…For example, in situ concrete can be damaged in the demolition process (Afify and Soliman, 2014). The material's embodied energy is the foremost factor in deciding on the suitability of that material either for reuse or recycling (Fuertes, 2017). According to this, processed components of high value, such as metal, plastics, bricks are better for reuse (Amponsah et al 2012).…”

The construction industry plays a significant role in the economic growth of a country. Nevertheless, the construction industry has created severe adverse environmental impacts. Therefore, green building technologies are implemented to alleviate the adverse effects of the construction industry. Using green materials instead of conventional building materials with high environmental impacts has been identified as one such implementation. However, there seems to be much confusion in defining green building materials. Hence, it is vital to explore the features of green building materials. Therefore, this article investigates green features that qualify the building materials as green building materials. A qualitative research approach was selected as the research methodology, and semi-structured interviews were conducted with seven green building experts. The data was analysed using content analysis. Findings revealed that recycled content, local availability of materials, embodied energy of materials, use of rapidly renewable material, usage of waste material for the production process, material wastage content in the production process and pollution prevention in the production process are the green features. The study results guide the identification of green building materials that can replace the materials with poor environmental sustainability.
