Assessing Life Cycle Related Environmental Impacts Caused by Buildings

Resumo: Investment decisions for buildings made today largely determine their environmental impacts over many future decades due to their long lifetimes. Fur thermore, such decisions involve a trade-off between additional investments today and potential savings during use and at end of life - in terms of economic costs, primary energy demand, greenhouse gas emissions and other environmental impacts. Since the economic system does not fully account for external environmental effects, environmental resources are used inefficiently. Life cycle assessment (LCA) is suited to complement economic information on buildings with information on their environmental impacts. LCA helps to take measures and action to increase the resource efficiency of buildings and construction.
The project is advancing the research already conducted within EBC Annexes 56 and 57. It broadens the scope of Annex 57 by including operational impacts of buildings in use and by addressing environmental impacts in addition to primar y energy demand and greenhouse gas emissions. It is the intention to cover residential, office and school buildings, hospitals and other public buildings, both new and retrofit.
The project is researching harmonization issues arising when applying LCA approaches on buildings. It functions as a platform to exchange experiences and knowledge within partner countries and to foster the application of LCA on buildings in countries with little experience yet.
The planned deliverables from this project are:
– harmonised guidelines on the environmental life cycle assessment of buildings,
– establishing environmental benchmarks for buildings (basics, methods, examples),
– national LCA databases used in the construction sector, including standardised characterisation of all relevant LCA databases,
– guidelines for planners on how to optimise the life cycle performance of buildings during the design process using planning tools such as BIM,
– building case studies using a standardised template,
– how to establish national or regional LCA databases targeted to the construction sector, and
– default publicly available, national data sets of LCA-based environmental indicators.
