Advanced renovation in Non Residential buildings
New construction accounts for approx. only 1% of the energy consumption in the total building stock. Therefore there is a great t need for and potential by implementing comprehensive energy conservation in existing buildings. In May 2010 the EU Parliament approved recast of the EPBD citing that member countries must establish objectives in order to stimulate energy renovation of existing buildings to become almost energy neutral buildings Nearly Zero Energy Buildings (NZEB). Examples of energy renovations have shown that it is possible to reduce the total primary energy consumption in buildings substantially and improve the indoor climate at the same time. Experience from these projects has not been systematically analysed, so energy targets for extensive renovations are often set too conservatively. Buildings already renovated to only mediocre levels may have lost the chance to achieve more ambitious levels, as profitability deteriorates substantially if further energy reductions are considered. The project ensures Danish participation in a new IEA Task 47 'Advanced in Renovation in Non Residential Buildings'. In this way Denmark participates in the development of solid knowledge of, how to energy renovated buildings to reach a NZEB level in a sustainable and cost-effective manner. Moreover, the most important market and policy obstacles for doing so will be identified. The project is of international character, so it is expected to encourage greater international cooperation on development and research on extensive energy renovation. The project could therefore be instrumental in ushering in energy renovation of large buildings and break down some barriers in this area. At a national level this will could results in a major energy saving potential as Danish companies will be able to access the latest knowledge and information about Rood and effective renovation examples
The main purpose of this project is: - To develop a solid knowledge of how to energy renovate non-residential buildings to achieve Nearly Zero Energy Buildings (NZEB) standards in a sustainable and cost-effective manner. - To identify the key market and policy barriers. and marketing strategies to implement such extensive energy renovations. A wide range of technologies will be assessed in the project, such as good ventilation and cooling solutions but obviously solar radiation and other renewable energy sources will also play a significant role in bringing the primary energy consumption for this type of buildings to the NZEB level. The project will have Danish participation in a new IEA Task 47, which has the overall objective of compiling existing knowledge from projects where extensive energy retrofit has been completed, and on this basis to develop guidelines for comprehensive solutions for efficient-energy renovation. This knowledge will be made available to building owners and others who face having to implement energy renovation. Thus, past experienced is effectively used for the whole construction industry. The project's background is IEA SHC Task 37: 'Advanced Housing Renovation With Solar Energy and Conservation', in which similar solutions are determined for buildings used for habitation. Other objectives for the EUDP project are: 1. To ensure Danish participation and contribution to the new IEA Task 47.: 2. To collect and process knowledge from existing projects in both Denmark and abroad. The knowledge will be gathered in a database of lessons learnt that can be applied to future energy retrofit projects.: 3. To make knowledge accessible and usable to make knowledge about how to implement far-reaching energy renovation of buildings to reach NZEB standards in a sustainable and cost-effective manner without compromising the indoor environment.: 4. To develop guidelines for comprehensive solutions to reduce energy consumption.: 5. To identify the key market and policy barriers, and marketing strategies to implement such extensive energy renovations
The objectives of the IEA Task 47 "Advanced Renovation in Non-Residential Buildings" are to develop a solid knowledge base on how to renovate non-residential buildings towards the NZEB standards in a sustainable and cost efficient way as well as to identify the most im-portant market and policy issues as well as marketing strategies for such renovations.
In the Task highly successful renovations and innovative concepts for the most important market segments have been analysed. To reach local authorities, companies and planners who need the knowledge on how to achieve market penetration using such solutions, the Task has to communicate success stories and planning knowledge with target audiences to support the acceleration of a market break-through of highly effective renovations in non-residential buildings. The EUDP project has ensured Danish participation in the Task.
