Project - Energy & greenhouse gas optimized building renovation (ANNEX 56)

Energy & greenhouse gas optimized building renovation (ANNEX 56)

Project start May 1st 2011. Project ended May 1st 2013.

Purpose of project
The purpose of the project is to ensure Danish participation in IEA Annex 56, where the main objective is to provide tools, guidelines, recommendations, best-practice examples and background information for policy makers, designers, users, owners and promoters that help cost effectively minimizing GHG emissions as well as primary non-renewable energy (RE) consumption in the existing building sector. RE production is also considered.

Objectives
The Danish participation in the IEA Annex 56 shares its objectives with IEA Annex 56. The main objective of this Annex is to help accelerate extensive energy renovation of the existing buildings in Denmark and worldwide. To reach this main objective 4 objectives have been identified:

•  Development of a new methodology as the basis for future standards, to enable cost effective renovation of existing buildings towards the nearly-zero energy and emissions objective. Extensive energy renovation of the existing building stock is essential and will to a great extend contribute to reach the energy political and CO2-reductions goals.
• Development of tools, guidelines, recommendations, best-practice examples (case studies) covering as well energy efficient building renovation as renewable energy production - for policy makers, designers, users, owners and promoters.
• The introduction of a broader approach going beyond the energy efficiency concept and focusing on the overall added value achieved in a energy renovation process, which means that comfort improvement (thermal, natural lighting, indoor air quality, acoustics, functionality, extra area achieved,etc.), global quality improvement and economic impact of the intervention in a cost/benefit perspective will also be considered.
• Directly link the IEA to the target audience through accessible language and tools that enables them to understand the benefits but also the problems and risks associated with building energy renovation.
