Demonstration of minimally invasive thermal and energy retrofits of classic 1950s - 60s apartment buildings
Abstract
Urban settlement areas face the unconditional challenge of converting their built infrastructures to completely climate-neutral energy applications within a maximum of two decades. The complete phase-out of fossil fuels for space heating was only recently fixed for 2040. In the heat supply sector, the numerous households heated with gas - about 400,000 in Vienna alone - pose a particular challenge. Since a changeover to green gas is not an option under the given energy and economic framework conditions, there is a need to switch to alternative systems of heat supply, for which district heating or heat pump applications are particularly suitable in Vienna. In the course of the research project, solutions for the efficient use of district heating and heat pump applications are investigated with the help of a facade-integrated heating system. The façade heating optimally tempers the building and minimizes heat losses to the outside. Existing buildings can be thermally activated in a sustainable way with this concept, without users and occupants being affected by structural measures. Domestic hot water is provided centrally or decentrally by heat pumps, which also use the external wall heating as a heat source. This results in two positive effects: First, it can ensure efficient hot water preparation all year round. Secondly, the use of heat from the façade can contribute to summer heat dissipation, as the issue of cooling will become more of a focus in refurbished residential properties in the coming years. The concepts will be tested and implemented in three demonstration buildings.
