“…However, Ismael (2018) argues that the schemes offer little to no guidance on how this assessment should be conducted, level of detail, what lifecycle stages should be included, etc. [72]. Furthermore, the schemes often measure performance based on average industry benchmarks (current building codes), and for the schemes to push for better building practices the performance goals need to be absolute [60].…”

The building sector is responsible for extensive resource consumption and waste generation, resulting in high pressure on the environment. A way to potentially mitigate this is by including environmental considerations during building design through the concept known as eco-design. Despite the multiple available approaches of eco-design, the latter is not easily achieved in the building sector. The objective of this paper is to identify and discuss what barriers are currently hindering the implementation of eco-design in the building sector and by which measures building designers can include environmental considerations in their design process. Through a systematic literature review, several barriers to implementation were identified, the main ones being lack of suitable legislation, lack of knowledge amongst building designers, and lack of suitable tools for designers to use. Furthermore, two specific tools were identified that allow the inclusion of environmental consideration in building design, along with nine design strategies providing qualitative guidance on how to potentially minimize energy and material consumption, as well as waste generation. This paper contributes a holistic overview of the major barriers to and existing tools and method for the eco-design of buildings, and provides guidance for both future research and practice.

“…A segunda corrente de corte de inventário praticada em ACVed pauta-se pela exclusão de componentes por subsistema construtivo, frequentemente observada na literatura (SOUST-VERDAGUER; LLATAS; GARCÍA-MARTÍNEZ, 2016) e adotada por certificações ambientais como BREEAM, LEED, DGNB, Green Globes e Green Star (ISMAEEL, 2018). A certificação LEED, por exemplo, incluiu o uso da ACVed para avaliação de materiais e recursos a partir de sua versão 4, porém considerando apenas elementos da estrutura e envelope (USGBC, 2013).…”

A escassa literatura disponível sobre avaliação do ciclo de vida de edificações (ACVed) aponta a necessidade de reduzir os fluxos considerados. As regras de corte auxiliam a viabilizar a modelagem, mas o efeito de variações na sua aplicação é inexplorado na literatura. O objetivo deste trabalho é investigar a influência da aplicação das duas principais abordagens de corte de inventário utilizadas em ACVed - por massa e energia, indicada pela norma EN 15804, e por subsistema construtivo, como adotado pela certificação LEED v4 - relativamente ao inventário mais completo possível (“best-of-knowledge”). Impactos do berço ao túmulo foram calculados para dois casos. A plataforma SimaPro v8.5/9.0 apoiou a composição dos processos e adaptações da base Ecoinvent. Foram utilizados os métodos CML-IA baseline e CED para avaliação de impacto, e clusterização k-means para prospecção de relações entre categorias ambientais. Enquanto a regra de corte europeia retém uma parcela considerável dos impactos em todas as categorias, os subsistemas excluídos pelo LEED afetam principalmente categorias não avaliadas, mas em que a produção de materiais de construção tem efeito relevante, como ecotoxicidades, toxicidade humana e depleção abiótica. Adicionalmente, a livre escolha de três categorias ambientais propicia redundância de informação, caso elas façam parte de um mesmo cluster. Para equilibrar a viabilidade da ACVed, enquanto se assegura a integridade das conclusões, recomendamos que a certificação adicione subsistemas na avaliação até que mais de 75% dos metais sejam computados, e amplie estrategicamente o conjunto de categorias avaliadas mandatoriamente. Estudos adicionais são agora necessários para confirmar estas proposições.

“… Haute Qualité Environnementale (HQE) From the rating systems analyzed in this report, HQE is the only one that does not clearly implement LCA (Ismaeel, 2018). Although the practical guide for non-residential building under construction considers LCA as one of the methods to limit the environmental impact of the building, it does not specify the basic technical criteria, such as the impact categories and the system boundaries (Cerway, 2014).…”

Environmental impact assessment (EIA) tools are key mechanisms that link the environmental context of a project to the decision-making framework. Life cycle assessment (LCA) and green building rating systems (GBRS) are the two approaches commonly used to holistically analyze the environmental performance of the whole building. While GBRS are mostly based on a checklist with many qualitative criteria, LCA compels the practitioner to base the analyses in numerical evidence, which facilitates the comparison between design choices. Some rating systems, such as LEED, BREEAM and Green Star, have been incorporating LCA as one of their criteria. This practice tends to increase in criteria-based tools, because of the market and governmental claims for better awareness of the construction industry ecological impacts. Therefore, the goal of this article is to discuss both whole building life cycle EIA tools, life cycle assessment (LCA) and green building rating system (GBRS), comparing their methodological concepts as well as the effort of combining both approaches. It was noticed that although there are many differences between EIA tools, the combination of both approaches would bring substantial benefits in identifying and mitigating the potential environmental impacts of buildings. Therefore, further research is needed to create a design process framework that unifies GBRS and LCA methodologies, providing a more comprehensive overview of a building's environmental impacts.
