Empire Building Challenge retrofit projects are expected to be transformative beyond traditional energy efficiency improvements, focusing . These projects focus on shifting thermal loads from fossil fuels to electric , and/or constitute enabling work that prepares building(s) for future electrification, such as projects that reduce thermal loads and thermal and electric peaks.

The Challenge is looking to advance three major technology focus areas:

A significant need exists for various format heat pumps (e.g., water-water, water-air, air-water, etc.) to allow for phased decarbonization, waste heat recovery, thermal storage optimization, retention of existing thermal distribution systems, and retrofits of a large office or residential building heating plants to significantly reduce or eliminate on-site fossil fuel consumption.
