Évaluation environnementale de systèmes de construction de cloisons résidentielles : réflexions sur l'adaptabilité et la flexibilité
The introduction of sustainable development brings new environmental concerns on an important Canadian market industry: construction and residential renovation. Not only does the current concept have a considerable impact on the environment, it also can’t follow up with the development of practices, technologies and occupants’ lifestyle. First, a literature review draws a picture of the construction, renovation and demolition industry (CRD) in Canada and it outlines the CRD rubbles management profile. Then a documentary analysis drafts different concept tools that were developed to improve the industry’s performance. They are 3RV-E, ecodesign, sustainable construction and LEED®. The papers review also explores the adaptability and flexibility concepts on the construction sector and on the emerging architectural trend. This approach brings us to the hypothesis that the integration of the adaptability and flexibility criteria to the housing sector will improve the adequacy between the progressive needs of the occupants and the new environmental issues. On a methodological perspective, the simplified lifecycle analysis performed with the Eco-indicator99 overviews the environmental analysis of three types of partition construction. The outcome of this evaluation is that the one with the less environmental impact is the traditional construction with a wooden framework, followed by the construction with an aluminum framework which is adaptable and flexible, and in third place, the construction with a steel framework which is the most harmful to the environment. On the other hand, adding the time factor to this analysis demonstrates that the integration of the adaptability and flexibility criteria brings a number of renovation and life cycles to the product and its components. In the end, these concepts present us with a potential of reducing the impacts of construction and renovation on the environment and that’s an assessment that would need to be approached systematically.
