Overview:

Summary: Waste heat contributes to the urban heat island effect and has been linked to overall warming. Heat pumps and heat recovery chillers can move heat to different locations to be applied to other uses instead of being vented directly onto the street.

Implementation: Offer incentives to property owners and industries to transition to systems that recycle, recover, and reuse waste heat through heat pumps and recovery chillers.

Considerations for Use: Waste heat reduction can happen through many of the solutions in this toolkit like district cooling, weatherization, mechanical cooling, among others.
