The next Annex 56 meeting will be held within the frame of the SB13 Conference in fall 2013. In the course of the meeting, an “Industry Workshop” will be arranged taking place in cooperation with the IEA EBC Annex 57 (Evaluation of Embodied Energy & Carbon Dioxide Emissions for Building Construction) and the EU project AIDA (Affirmative Integrated Energy Design Action).

In the future at least 2/3 of the upcoming construction activities will be renovation works. This is an opportunity to renovate buildings not only barely but thinking about long-term cost effective renovation opportunities and exploit the potential of the existing building stock for the reduction of energy consumption and carbon emissions.

The aim of the research project Annex 56 is to develop a methodology to evaluate and analyse cost effective building renovations which optimise energy consumption and carbon emissions reduction. Similarly, the development of the necessary tools and instruments to support decision makers is another research focus. The methodology will be developed and applied for testing on case studies, which are characterized including energy conservation and efficiency measures as well as measures for the use of on-site harvested renewable energy. The resulting, quantitatively elusive co-benefits, should also be demonstrated as well as the relevance of including a life cycle impact assessment in the evaluation of renovation measures.

The AIDA project aims to accelerate the market entry of nearly zero-energy buildings (nZEB). This means energy efficient buildings and the use of renewable energy sources, which are both highlighted in the IEE2011 work program. Currently there is a lack of intense actions to spread knowledge about nZEB. It is evident that citizens will be better prepared and more willing to adopt nZEB if their municipality sets an example thus giving them direct access to and experience of nZEB. Raising awareness towards nZEB among local authorities and building planners becomes a key factor. AIDA offers action tailored to suit each of these groups including study tours, operational success stories, presentation of existing tools, active support of municipalities and close cooperation with key actors.

The IEA EBC Annex 57 focuses on “Evaluation of Embodied Energy and Carbon Dioxide Emissions for Building Construction”. The state of the art for embodied energy and CO2 emissions due to building construction as well as results from existing research projects are being analyzed and summarized. As embodied energy/carbon dioxide occupies large part of the whole energy consumption and carbon dioxide emissions especially in the countries where the building construction activity is enormous, need for evaluation of them with scientific basis is increasing among building designer, developers, building material manufacturers and policy decision makers in many countries.

More important issue than the evaluation is how to decrease embodied energy/carbon dioxide in practice in building construction field. As there is a large potential to decrease the embodied energy/ carbon dioxide due to the building construction according to the literatures, the measures will be great issue in Annex 57.
