“…Consideration of volatile organic compounds (VOC) emissions is an attempt to advance from previous work focusing on resource use and ecosystem quality (SAADE et al, 2012;OLIVEIRA;SILVA, 2013) and enlarge the assessment scope to include information on human health aspects. From the impact categories suggested by EN 15804:2012 that are more frequently found, POCP is the only one that alludes to human health issues.…”

The International Energy Agency (IEA)'s Annex 57 was established to advance on evaluation of embodied energy and GHG emissions for building construction. Its activities include recommendation of common calculation methods and disclosure of regional benchmarks. Process-based, input-output or hybrid life cycle assessment (LCA) can support such calculations. Identification of the major products that describe key building typologies plays a strategic role in the tasks of streamlining indicators' monitoring scope and LCI data gathering in contexts with little LCA practice consolidation. Given these motivations and backdrops, our main goals are (i) to calculate a selected set of LCA-based indicators to synthetically describe environmental performance of construction products for three functionally equivalent case studies; (ii) to detect the major contributors to embodied energy (EE) and emissions (EGWP); and (iii) to examine the implications of considering embodied CO 2 versus total GHG emissions. The selected metrics include -besides EE and EGWP targeted by Annex 57 -the blue water footprint (bWF), non-renewable primary material consumption (NRc) and volatile organic compounds (VOC) emissions. Production cycle modeling used previously collected national data, as well as secondary data extracted from national and international literature or adapted from international databases whenever considered as reasonably similar to Brazilian processes. EE and EGWP results were calculated using the Cumulative Energy Demand (CED) method and the CML 2001 baseline v. 2.05 method, respectively, and are presented for the top contributing products. NRc, bWF and VOC calculations were directly derived from the inventories and discussed in more detail for cement and concrete. Around 80% of the total embodied energy was related to seven construction products, while four of them also responded for around 80% of embodied GWP. Enlarging the database to encompass ten core products would increase coverage to over 93%. For cement and concrete, partial replacement of clinker by ground granulated blast furnace slag brought substantial reductions in the calculated values for all indicators but bWF, which unveils the effect of the water-intensive granulation process. Further research is expected to advance in LCI development and validation to enable the use of life cycle-based metrics to support decision-making within the national building sector. RESUMO O Anexo 57 da Agência Internacional de Energia (AIE) foi estabelecido para avançar na avaliação de energia e emissões de GEE associadas à construção de edificações. A avaliação de ciclo de vida auxilia no cálculo destes indicadores. Identificar os principais produtos de construção que descrevam tipologias construtivas-chaves tem um papel estratégico na otimização do monitoramento de indicadores e construção de inventários em contextos com práticas de ACV pouco consolidadas. Este artigo é dirigido por estas motivações. Nossos objetivos são: (i) calcular um conjunto selecionado de indicadores...

“…Carvalho (2009) and Carvalho and Sposto (2012) proposed global sustainability indicators for projects and specifications for wall systems (facades and partitions), based on environmental, social and economic criteria for social housing. Oliveira, Silva and Gomes (2013) proposed environmental and economic performance indicators for the project of concrete structures. However, they did not address criteria related to the social aspects of sustainability and for other construction elements.…”

Objetivo do estudo: Este trabalho tem como objetivo dar continuidade ao desenvolvimento e aplicação da ferramenta para análise de sustentabilidade de projetos de habitações de interesse social (HIS), denominada MASP-HIS, que foi aplicada em alguns elementos deste tipo de edificação. Metodologia/abordagem: Os critérios elaborados para essa avaliação têm como base os aspectos ambientais, socioculturais e econômicos, a partir dos quais é possível avaliar o projeto completo e também as especificações dos sistemas de uma habitação isoladamente. A avaliação foi realizada para um estudo de caso. Originalidade/Relevância: O trabalho apresenta uma ferramenta versátil e adaptável a diferentes projetos de HIS. Ela tem o potencial de avaliar sistemicamente diferentes aspectos de sustentabilidade (ambiental, sociocultural e econômico), levando em conta a diversidade dos materiais e elementos construtivos empregados no projeto. Principais resultados: Podem ser analisadas diferentes combinações dos materiais, componentes e elementos especificados. Foram desenvolvidos os sistemas de estrutura, cobertura e esquadrias. Contribuições teóricas/metodológicas: O uso da ferramenta pode subsidiar e facilitar a especificação de projetos de HIS com critérios de sustentabilidade. Conclusão: Ao final foi possível obter o índice de sustentabilidade global para diversas combinações de um projeto de HIS.
