Within this project the potential of large thermal energy storages to facilitate the decarbonisation and simultaneous expansion of thermal networks are analysed. Different techniques of short-, medium- and long-term heat storage are considered. The focus is on the replacement of fossil peak load, the increased integration of waste…
The seasonal storage of heat in 100 % solar thermal heated single and multifamily buildings has been implemented in a number of projects in Switzerland. The first multifamily building with seasonal thermal energy storage that uses a combination of PV and heat pump instead of a solar thermal system is currently being built in…
Sorption heat pumps can provide cooling based on renewable district heat or waste heat, thus expanding the scope of district heating networks (DHN) and making better use of existing renewable heat sources. On the other hand, sorption heat pumps in district heat transfer stations can also provide heat while significantly reducing…
Within the OptimEase project, a modelling framework is developed that allows for the energetic optimization of groups of buildings by using their synergies. By comparing the optimal solution of a group of buildings with the sum of optimal solutions for each individual building, the economic and environmental benefits of aggregating…
Experience from various pilot and demonstration projects, as well as the assessment of experts, suggests that heating and cooling systems are often oversized. However, since there were no systematic studies on this topic in Switzerland, the Swiss Federal Office of Energy (SFOE) commissioned the SPF and the IET - Institute of Energy…
Geothermal heat pumps are efficient heating systems and therefore they can provide a substantial contribution to the reduction of CO2 emissions of the Swiss building park. In reverse operation mode, they can also cover the increasing cooling demand of buildings. However, the SIA 180 standard asks for passive measures to prevent…
