Abstract: Waste heat recovery combined with geo-exchange is a key part of the net-zero carbon strategy proposed for the Centre Block Rehabilitation project. The project will create large below-grade areas which will need year-round cooling. We propose that this heat be re-used for space heating through the use of a water-to-water heat pump. The energy model for the project was created in IESVE, which does not include a native model for a loop-to-loop heat recovery system. We present a spreadsheet tool developed to carry out external calculations and model the potential energy and carbon savings from waste heat recovery.
