IEA-EBC Annex 72: Assessment life cycle related environmental impacts caused by buildings
The Executive Committee of the International Energy Agency Energy in Buildings and Communities programme (IEA EBC) approved the “IEA-EBC Annex 72: Assessment life cycle related environmental impacts caused by buildings” in 2016. The project will run till 2021.
In support of the principal aim of reducing the primary energy demand, greenhouse gas emissions and other environmental impacts along the entire life cycle of buildings (construction, use and end of life), the project is working towards the following objectives:
- establish a common methodology guideline to assess the life cycle based primary energy demand, greenhouse gas emissions and environmental impacts caused by buildings;
- establish methods for the development of specific environmental benchmarks for different types of buildings;
- derive regionally differentiated guidelines and tools for building design and planning such as building information modelling (BIM) for architects and planners;
- establish a number of case studies, focused to allow for answering some of the research issues and for deriving empirical benchmarks;
- develop national or regional databases with regionally differentiated life cycle assessment data tailored to the construction sector;
- share experiences with the setup and update of such databases.
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 life cycle analysis (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.
