ICAST created a Resource Guide to help multifamily owners and managers, policymakers, utilities, energy efficiency program implementers, and others, advance the deployment VHE heat pump HVAC and water heaters in multifamily housing.  VHE heat pumps can help reduce utility bills, cut carbon emissions, and preserve and improve affordable housing. Mass deployment of VHE solutions can also benefit the power grid, create local jobs, and stimulate local economic development. Though the focus of this guide is multifamily properties, it can be applicable across the spectrum of buildings, from single-family homes to commercial buildings.
