Evaluation and Optimization of Underground Thermal Energy Storage Systems of Energy Efficient Buildings (WKSP)- A Project within the new German RD- Framework EnBop

摘要

Until 2003 the research on buildings in operation in Germany focused mainly on demonstration buildings. Starting with the EVA project managed by IGS the attention is shifting towards performance in operation. The paper gives a general review of these research projects and presents detailed results of project WKSP. The performance of buildings with systems for underground thermal energy storage is analysed in this project. As the analyses show several systems work worse than expected. Within the project most of the systems could be significantly improved in operation. The scientific work on building performance in operation will be broadened within the new R&D framework EnBop. IGS will coordinate the framework funded by the German Ministry of Economics and Technology.
