BREEAM (Building Research Establishment Environmental Assessment Method) is widely recognized for promoting environmental sustainability in the built environment, with a strong focus on energy efficiency, resource management, and ecological impact. However, as sustainability entails environmental and economic dimensions but also social dimensions, the current BREEAM New Construction standards do not fully address social sustainability targets. This article explores the potential for expanding BREEAM New Construction standards to more comprehensively incorporate social sustainability, ensuring that certified projects contribute to the well-being of their occupants and surrounding communities. Through a review of existing BREEAM categories, technical manuals, standards, and an analysis of gaps related to social sustainability, this paper identifies key areas for potential improvement, including user satisfaction, protecting workers’ and human rights, legacy planning, education and skills, and emergency response planning. These gaps are mapped against existing BREEAM categories and credits, with recommendations to introduce additional credits across the categories of management, materials, energy, waste, land use and ecology, health and well-being, and water. Additionally, this paper highlights the importance of transdisciplinary collaboration—bringing together architects, urban planners, social scientists, and public health experts—to effectively address the complexity of social sustainability in building design and certification. The proposed additions to BREEAM New Construction standards, alongside recommendations for industry and policymakers, offer guidelines for the evolution of green building certifications toward a more holistic approach to sustainability. This shift ensures that future certified buildings reduce environmental impact and promote social equity, health, and community well-being simultaneously. Full article

To achieve the ambitious CO₂ emission reduction targets set by the Sustainable Development Goals, it is crucial to act on cities. Indeed, cities are responsible for 67% of the world’s primary energy consumption and about 70% of energy-related CO₂ emissions. To support the urban energy transition, a broad implementation of zero-emission districts or, even better, positive energy districts (PEDs) is expected. PEDs can be defined as energy-efficient and energy-flexible urban areas that aim to provide a surplus of clean energy to the city by using renewable energies. However, in developing the PEDs concept, it is necessary to consider not only the technical issue of energy systems but also the environmental, social, and economic spheres. To be effective, it is important to provide decision-makers with tools such as Urban Sustainability protocols for PEDs, which can effectively assess the complexity of the impacts a PED might have on other urban transformations from a multi-stakeholder perspective. LEED for Neighborhood Development, BREEAM Communities, and CASBEE for Cities are the most widely used and known protocols in the world for the evaluation of districts. These certification protocols were established before the concept of PEDs and, therefore, are not considered. However, they exhibit some shared characteristics which permit the evaluation of PEDs’ sustainability. In fact, through this research, an attempt is made to analyze how the implementation of sustainability protocols in existing PED projects can improve sustainability, but also how PED projects can improve evaluation systems through interventions that have not been considered so far. To test a methodology that could be extended in future case studies, an analysis of three of the world’s best-known certification systems, LEED-ND, BREEAM-CM, and CASBEE-UD, was conducted on two completed PEDs case studies, Tampere and Salzburg.

The concept and practice of sustainability in urban planning have gained worldwide significance since the early 2000s and have become increasingly mainstream in the policymaking process. Adopting global frameworks, such as the United Nations Sustainable Development Goals and ISO standards, for sustainable communities provides an opportunity to build more sustainable, innovative, and equitable towns and cities, with regard to natural resources and biodiversity. However, attaining sustainability requires addressing many fundamental issues at various levels, and achieving the goals and objectives of sustainability poses a significant challenge for all segments of society. Several methods for assessing the sustainability of the urban environment have been established in recent years. Therefore, compiling a short and comprehensive list of indicators addressing the broad concept of urban sustainability issues has arisen as a significant challenge. This research reviews four urban sustainability assessment tools—BREEAM-C, LEED-ND, iiSBE SBTool^PT Urban, and iiSBE SNTool—to identify a clear set of key sustainability priorities. This study aims to highlight a more consistent list of indicators that are considered the most significant aspects and priorities within the analysed sustainability methods, allowing for a common understanding of the most important principles that must be considered in the design of sustainable urban areas and are compatible with the most recent standardization and sustainability targets. The end product of this study includes a proposal for a set of sustainability indicators to assess environmental, social, and economic issues to implement in the design of sustainable urban environments, independent of the local context.

This article reports on a critical review of how cultural heritage is addressed in two internationally well-known and used neighborhood assessment tools (NSAs): BREEAM Communities (BREEAM-C) and LEED Neighborhood Design (LEED-ND). The review was done through a discourse analysis in which critical heritage studies, together with a conceptual linking of heritage to sustainability, served as the point of departure. The review showed that while aspects related to heritage are present in both NSAs, heritage is re-presented as primarily being a matter of safeguarding material expressions of culture, such as buildings and other artifacts, while natural elements and immaterial-related practices are disregarded. Moreover, the NSAs institutionalize heritage as a field of formal knowledge and expert-dominated over the informal knowledge of communities. Full article

The use of tools to measure the degree of sustainability of cities is the approach that receives the most attention in developed countries. However, studies of evaluation tools at the neighborhood level reveal that there are many weaknesses in the most widely-used evaluation systems (LEED-ND, BREEAM Communities, CASBEE-UD). There are ambiguities and gaps in weighting and in scoring and in most cases, there is no mechanism for local adaptability and participation. The purpose of this study is to provide an overview of the current situation by highlighting the strengths and weaknesses of these evaluation tools in order to integrate social and economic aspects for the improvement of the CASBEE-UD (neighborhood level) evaluation tool. The selection of socio-economic aspects was made through the use of a multi criteria Analysis Hierarchical Process (AHP) and a Geographic Integration System (GIS). The results of this case study indicate that most evaluation tools need to be revised because most do not include socio-economic aspects. We have demonstrated that applying the CASBEE-UD assessment tool integrated with socio-economic aspects to four boroughs in the City of Montreal can measure success by addressing the objectives of sustainable development.

Traditionally, the energy efficiency in buildings has been evaluated through well-established protocols that highly depend on Key Performance Indicators (KPI). However, nowadays, the trend has moved from buildings to districts and cities where not only energy efficiency is pivotal, but also the sustainability under the scope of smart city. There exist several widely recognized environmental assessment methodologies such as BREEAM or LEED that aim to assess the sustainability of buildings based on a rating system represented by a set of indicators, namely credits. Nevertheless, the application of these standards is complex and costly. Hence, this paper presents an alternative holistic sustainability protocol, developed under the European project CITyFiED, driven by a comprehensive set of indicators to assess the sustainability of urban areas in terms of energy efficiency, environmental, economic and social impact, together with the effect of the information and communication technologies.

Rating systems for assessing the environmental impact of buildings are technical instruments that aim to evaluate the environmental impact of buildings and construction projects. In some cases, these rating systems can also cover urban-scale projects, community projects, and infrastructures. These schemes are designed to assist project management in making the projects more sustainable by providing frameworks with precise criteria for assessing the various aspects of a building’s environmental impact. Given the growing interest in sustainable development worldwide, many rating systems for assessing the environmental impact of buildings have been established in recent years, each one with its peculiarities and fields of applicability. The present work is motivated by an interest in emphasizing such differences to better understand these rating systems and extract the main implications to building design. It also attempts to summarize in a user-friendly form the vast and fragmented assortment of information that is available today. The analysis focuses on the six main rating systems: the Building Research Establishment Environmental Assessment Methodology (BREEAM), the Comprehensive Assessment System for Built Environment Efficiency (CASBEE), the Deutsche Gesellschaft für Nachhaltiges Bauen (DGNB), the Haute Qualité Environnementale (HQE^TM), the Leadership in Energy and Environmental Design (LEED), and the Sustainable Building Tool (SBTool).

Sustainability assessment tools have been developed for building-scale sustainability since the 1990s. Several systems, such as BREEAM (Building Research Establishment Environmental Assessment Methodology), LEED (Leadership in Energy and Environmental Design) and CASBEE (Comprehensive Assessment System for Built Environment Efficiency), are widely used and have been upgraded and adapted to large-scale development. BREEAM Communities, LEED Neighborhood Development and CASBEE for Urban Development have been implemented in the UK, the USA and Japan, respectively. As the notion of sustainable urban design has gained more significance, city governments have set their own guidelines for sustainable standards in urban design based on studies of sustainability assessment tools. This study focused on a comparative analysis of the material criteria embedded for sustainable urban design in BREEAM Communities, LEED-ND (Neighborhood Development) and CASBEE-UD (Urban Development), and the urban design guidelines recently issued in multiple cities, including London, New York, Tokyo, and Seoul. The top master plans and the supplementary guidelines were analyzed to investigate the detailed material criteria. The study examined the differences in the material assessment criteria, evaluation parameters, and descriptions of the neighborhood sustainability assessment tools and the urban design guidelines. The material criteria was investigated and discussed to summarize the current features and weaknesses as balanced material assessments for sustainable urban development. Full article

Owners and municipalities face the choice to renovate or rebuild buildings in order to improve energy efficiency and sustainability. The process of upgrading the existing building stock can be supported by land management tools, i.e., municipal energy plans (MEP) or sustainable building codes (BC), that municipalities use to plan, check and monitor actions taken. Many local and regional authorities are involved in the Covenant of Mayors supported by the European Union (EU): the sustainable energy action plan (SEAP) is the key document in which the Covenant signatory outlines how it intends to reach CO₂ reduction target by 2020. Sustainability at the urban scale is also supported by voluntary certification schemes such as Leadership in Energy and Environmental Design (LEED)^® for neighbourhood development proposed by the United States Green Building Council (USGBC), Building Research Establishment Environmental Assessment Method (BREEAM) Communities proposed by UK Building Research Establishment (BRE) and Comprehensive Assessment System for Built Environment Efficiency (CASBEE) for Urban Development proposed by the Japan GreenBuild Council. The fact that there are so many tools to manage urban sustainability is positive, but what happens when multiple tools are applied to the same territory? Overlap, redundancy, and conflicts in management may be critical elements. The purpose of this article is to analyze these critical issues, highlighting the elements of integration and possible synergies for effective management of sustainability at the local level.
