Residential heating and cooling have long been a target of energy efficiency projects and efficiency program portfolios. Exciting new opportunities expand on long-standing envelope and HVAC system upgrades and further reduce the energy required for space conditioning in homes. These include new and innovative technologies, but also new information tools and program design and implementation approaches to better align energy efficiency and the interests of both electric and gas utilities. In this webinar, ACEEE will summarize findings of two new briefs in its Emerging Opportunities in Buildings Series covering 1) Residential Window Attachments and 2) Dual-Fuel Programs. Attendees will also hear from some of the experts that contributed their knowledge to the briefs.
