Direct Excess Heat Utilization from a High Performance Computer in an Existing Unrenovated Building: A Case Study
Abstract
This study quantifies the savings potential of fossil district heat for the case study of the architecture building of the TU Darmstadt by directly using excess heat of a high performance computer (HPC). It is based on the already implemented demonstrators of a hot water cooling system for the new HPC and on the integration of low temperature ceiling heating systems in the otherwise unrenovated architecture building. As a result, with an excess heat utilization rate of 54 %, more than half of the building’s district heating demand can be saved.
