IEA EBC Annex 57: Evaluation of the design-specific CO2 emissions and the gray energy

The IEA-EBC Annex 57 evaluated methods of construction-related embodied environmental impacts and embodied energy and related international best practice projects and their approaches. Based on these findings, methodological guidelines as well as measures for their application at the international level and for the planning of buildings - with lower embodied energy and embodied greenhouse gas emissions - were derived.

Short Description

In addition to participation in the international and national meetings, the Austrian cooperation focused on the content of the work packages 2 to 5:

  • Content collaboration:
    - Literature Evaluation / State of Research - Subtask 2
    - Evaluation Methods - Subtask 3
    - Case Studies - Subtask 4
    - Reports and Dissemination - Subtask 5
  • Networking and dissemination activities

As part of this work, national assessment methods, case studies and know-how were incorporated into the international cooperation project. An essential part was the international dissemination of national demonstration building projects from the House of the Future Plus Technology Program (for example, plus energy renovation Kapfenberg, Energy City Graz Reininghaus, and many more), Furthermore, these demonstration building projects were presented in the context of dissemination measures to the international trade audience.

Due to the expansion of the content of the international cooperation project, Austria based its existing expertise on the preparation of a guideline for manufacturers of construction products (Guideline for Construction Products Manufacturers: Guidance to include Embodied Energy & Embodied GHG Emissions in the decision-making process for SME's.

All Austrian results were disseminated as part of the participation in the joint, international annex dissemination and preparation of the international publication. The know-how gained and the findings from the current international cooperation project were distributed to target groups in Austria.
