Webinar Description

A virtual webinar, held over 1 hour.

Dual‑fuel heating is often overlooked in decarbonization strategies, yet it can play a key role in reducing emissions. This webinar will explore how supplemental heating choices for air‑source heat pumps (ASHPs), including dual‑fuel configurations, affect greenhouse gas emissions across U.S. regions and climate zones. Using whole‑building energy modeling, the session highlights why region‑specific approaches are essential for effective decarbonization. Attendees will learn how different supplemental heating options influence long‑term emissions outcomes and how to apply these insights to optimize HVAC system design while balancing cost and infrastructure constraints.
