Abstract

The content of the report serves as guidelines for design decision-makers on how to use available information to perform Life cycle assessment (LCA) of buildings during their design process. The building designers and person involved into the planning process are systematically guided through the design steps focusing on the following questions:

- How can the goal and scope of the LCA be linked with the design steps?
- How can the LCA inventory and the data involved in the LCA be organized?
- Which tools can be used?
- Which workflows can be used?
- How can design-related uncertainties be reduced in the workflow?
- How can LCA results be visualized, interpreted and communicated?

These guidelines summarize selected the results and recommendations of several background reports of tasks performed within the IEA-EBC project Annex 72 dealing with the "Assessing Life Cycle Related Envi­ronmental Impacts Caused by Buildings". The overall goal of the project is the harmonization of the methodology and salvation of issues which arise when applying LCA approaches on buildings.

The objectives of the project are:

To establish a common methodology guideline to assess the life cycle based primary energy demand, greenhouse gas emissions and environmental impacts caused by buildings;
To establish methods for the development of specific environmental benchmarks for different types of buildings;
To derive regionally differentiated guidelines and tools for building design and planning such as BIM for architects and planners;
To establish a number of case studies, focused to allow for answering some of the research issues and for deriving empirical benchmarks;
To 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.
