Measurements of the Performance of the Room Integrated PCM in the New Energy Efficiency Center
Abstract
The design of the Energy Efficiency Center, located in Würzburg, Germany, has as an overall aim to create a reference building which implements innovative techniques, serves demonstrational purposes, and is used for research and development in the field of energy optimized buildings. As the outer shell of the building as well as the interior construction is lightweight because of flexibility requirements and resource saving aspects, little heat storage capacity is available to buffer temperature fluctuation. To avoid room climates outside the comfort range without integrating too large conventional cooling power reserves, a combination of several thermal energy storage technologies is implemented to meet the cooling demand in an energy efficient way. One of the thermal energy storage technologies involves the integration of PCM in building materials, as well as an individually optimized cooling ceiling with PCM. Specifically, the prototypes of PCM cooling ceilings were investigated regarding their dynamic thermal behavior before being implemented in the EEC. In this work, the cooling concept with integrated PCM in wallboards, as well as the cooling ceiling with PCM is briefly presented. Subsequently, the first measurement results of the intense long-term monitoring of the performance of the integrated PCM are presented and analyzed.
