Ferramenta de avaliação de sustentabilidade de edifícios desenvolvida para o mercado português. É uma ferramenta de avaliação de desempenho ambiental, social e econômico que ajuda a avaliar a sustentabilidade de edifícios em diferentes fases do ciclo de vida, desde o planejamento e projeto até a construção, operação e manutenção.
Sustainability assessment and rating of buildings: Developing the methodology SBToolPT–H
Ricardo Mateus, Luís Bragança
Abstract
Although sustainable building is a multidimensional concept, attention to the issue often focuses solely on environmental indicators, ignoring the substantial importance of social, economic and cultural indicators. Building sustainability involves various relations between built, natural and social systems and therefore comprises a complex of different priorities that require consideration at each stage of a building’s life-cycle. To cope with this complexity and to support sustainability systematic, holistic and practical approaches to building design need to be developed. The main objective of a systematic methodology is to support the development of a building design that achieves the most appropriate balance between the different sustainability dimensions, and is, at the same time, practical, transparent and flexible enough to be easily adapted to different types of buildings and technology.
It is the aim of this paper to present an innovative approach for developing building sustainability assessment and rating, and to contribute to the evolution of generic methodology and international understanding by introducing an approach which takes the different dimensions of sustainability into account. The scope of the methodology presented in this paper (SBToolPT–H) is to assess the sustainability of existing, new and renovated residential buildings in urban areas, specifically in the Portuguese context.
Sustainable building design: Analysing the feasibility of BIM platforms to support practical building sustainability assessment
José Pedro Carvalho, Luís Bragança, Ricardo Mateus.
Abstract
Due to the time-consuming and complicated process of performing Building Sustainability Assessment (BSA), this is usually incompatible with construction companies’ deadlines. With the emergence of Building Information Modelling (BIM) in the construction industry, the opportunity for BSA methods to adopt and benefit from BIM arises. Following a previous study, this paper aims to put in practice a proposed theoretical approach to facilitate the implementation of the BSA since the preliminary design stages using, as an example, the Portuguese SBToolPT-H method. Therefore, this paper analyses how BIM platforms can contribute to optimising the BSA evaluation. To achieve this goal, a case study was modelled and characterised in Autodesk Revit and, tailored parameters were created to support the assessment. The results show that Autodesk Revit can support the evaluation of 13 SBToolPT-H sustainability criteria, in a faster and automated way when faced with the traditional assessment process. The capabilities of BIM platforms and its wider use by designers can significantly contribute to the integration of BSA methods in the BIM collaborative process, thus contributing to a more sustainable built environment.
Optimising building sustainability assessment using BIM
José Pedro Carvalho, Luís Bragança, Ricardo Mateus.
Abstract
The construction industry is responsible for various negative impacts on the environment leading to an increasing demand for sustainable buildings. There are several Building Sustainability Assessment (BSA) methods that allow designers to assess and optimise the building sustainability level. Due to the potential of Building Information Modelling (BIM), the opportunity for BSA methods to adopt and benefit from BIM arises. Despite the benefits in the approach simplification for assessing building sustainability, so far the method has not been used comprehensively in the evaluation process. This paper analyses how using BIM can contribute to optimising BSA methods, focusing on the SBToolPT-H. BIM applicability is assessed and a framework for a BIM-based application – SBToolBIM – is proposed. BIM is still not oriented to sustainable building, but it has great potential. For the SBToolPT-H, results show that it is possible to directly and indirectly assess 24 out of 25 criteria using BIM.
