Lehen is the largest district of City of Salzburg; close to the city centre and with high quality of infrastructure of public transport. Since the last decades the district was confronted with essential changes. The use of the area of the former utility means a huge potential for further development of the district. High share of renewable energy should be the main focus of the project; considering existing heat supply with district heating. High standards of buildings and large-scale solar system are the main elements of the energy concept. The use of a heat pump ensures an efficient increase of solar gains and leads to low primary energy demand resp. CO2-emissions. The new building area was also seen as a chance for modernization activities in existing building stock around. Energy efficient pumps and lightning as well as PV modules in the facades will ensure high share of renewable energy also for electricity demand. First results show the way for further projects – concerning effective steering of complex processes and technologies to achieve total CO2-reductions in urban areas.
