The aim of the project is to systematically study the potential for thermal energy storage in the Swedish building stock. The project is divided into two stages where the first is to develop a broad and generalised knowledge base on systems with thermal storage that can improve energy efficiency in buildings, something that has not been collected before. The second stage will comprise indepth studies of chosed applications that have been identified as promising in the first stage as being suitable for implementation in renovation and construction of new buildings. However, no practical exmperiments or demonstrations are planned within this project, rather the theoretical framework will be couple to case studies.
25% of Sweden's energy use is required to maintain the thermal comfort standard required by people in buildings. The requirements are greatest for heat but energy use for cooling is also significant and in fact increasing. Efficient energy storage can lead to increased energy efficiency in both heating and cooling systems through more optimal use of the production plant. For certain renewable energy forms such as solar heat, thermal storage is a necessity for efficient utilisation of the energy source.
