Energy Efficient Comfort in older apartment blocks

There are 600.000 apartment blocks built before 1960, and most of these are without insulation and modern ventilation. Renovation of these happens in ways, either for the whole building or apartment to apartment, often associated with the replacement of tenant/owner, and usually without taking sufficient account of energy conservation and indoor climate.
This project will ensure that energy conservation and indoor climate aspects are considered more, and support that the focus on these are intensified. The project aims to develop mature solutions for the energy and indoor climate optimization of buildings with facades worth preserving, so that both comfort and energy consumption are brought to a standard that is close to the new building. The project builds on the experience of EUDP project in Ryesgade 30. Experience from this suggests that for internal insulation and ventilation there are challenges and opportunities. Therefore, the project focuses on these topics. Exploitation of building integrated renewable energy production will be involved.
Since the Ryesgade 30 project was started in 2010, there has been a rapid development on the supply side in the insulation and ventilation material and equipment. Therefore, the project will involve a wider group of supplies with solutions that fulfill the equipment for renovation, energy conservation and indoor air quality. As in the Ryesgade project also contractors are included to ensure optimization all the way in the chain.
The project team includes Dresden University, who is the leader in insulating in Germany, and working with the same issues to optimize energy and indoor climate without getting structural problems. In a project Dresden TU is investigating different materials for interior insulation in historic buildings. Dresden University also has a calculation program (Delphin) for the analysis of moisture and temperature conditions with insulating material that will be used.
The project is divided into two phases, and this application only includes support for Phase 1. Phase 1 will include analysis, design, testing and selection as well as a process in which it is clarified in which situations the different materials and methods is the best suited. There are tests in laboratory and in one or more test apartments, and the results are documented in a showroom. The effect on energy and climate will be priced along with an assessment of the restoration value and reduced maintenance costs in the future.
Phase 2 consists of a demonstration in 1:1 of the developed solutions, both renovations of an entire apartment block, and as renovation apartment by apartment, according to a plan. Support for Phase 2 will be applied for later. The results of Phase 1 will be included in the decision making for demonstration projects in Phase 2 and in dialogue with owners and tenants as a basis for their acceptance of the project.
