Energy and greenhouse gas optimized building renovation (IEA)
The main objective of this project is to help accelerate extensive energy renovation of the existing buildings in Denmark and worldwide.
The Danish participation in the lEA Armex 56 shares its objectives with TEA Annex 56. The main objective of this Annex is to help accelerate extensive energy renovation of the existing buildings in Denmark and worldwide. The energy saving potential by energy renovation of existing buildings in Denmark is very large since 40% of the total energy consumption is used in buildings and most of the building stock is in poor condition regarding energy performance. Implementation of the potential energy renovation throughout the building stock in Denmark will to a great extend contribute to reach the goals for energy supply security and CO2-reductions. However only few ofthe potential energy saving solutions is. accomplished. One of the barriers for conducting energy saving retrofit measures might be lack of knowledge on how the renovations should be handled the right way and which specific measures that will give the largest savings in the actual building. Therefore there is a need for guidelines describing the best energy renovation measures for different types of buildings. The work in lEA Annex 56 is to be organized within 4 subtasks: 1) Development of a methodology for defining standards for energy renovation that can be adapted and applied by different countries with different conditions. 2) Development of modular and flexible tools, with different levels of complexity and a renovation guideline. 3) Case-studies will be used as sources of relevant technical information and as ways of testing the proposed methodologies. 4) User Acceptance and Dissemination
At the end of the project it is expected to achieve the following outputs:
- A methodology for setting up standards for energy renovation of buildings.
- Flexible decision making tools and guidelines in the perspective of users, owners and promoters, designers and policy makers;
- Commented successful case-studies highlighting the added-value of each rehabilitation process;
- A renovation guide based on cost effective solutions and on an optimal value concept.
Danish participation in and contribution to IEA Annex 56 is important as the outcome of the project may form the basis for a future EU directive on the energy performance of existing buildings.
