Hot Water Forum Overview
The ACEEE Hot Water Forum (HWF) is the premier technical conference dedicated to making water hot, distributing it with low losses, and using water with efficient fixtures and practices. Since 2008, the ACEEE HWF has brought together experts and newcomers from manufacturing; distribution (plumbing); electricity, gas and water utilities; government; and the research community's opportunities to learn from each other and build momentum for market transformation. Since then, the conference has emphasized both the technical efficiency potential and the policy/program implications of service hot water technology and practices, and how people use hot water. Each year, the forum features more than 32 sessions covering cutting-edge developments in these areas.
HWF participants meet, share ideas, and learn from each other's latest efforts on research, new water heating technologies, structured plumbing approaches, new demand-reduction devices (e.g., fixtures and water-efficient appliances), and programs for stimulating market uptake of new approaches. The HWF presentation program, developed each year by a dedicated steering committee, is complemented by ample time for networking with fellow attendees.
Likely Participants Include: Equipment and component manufacturers; water, gas, and electric utilities; local, state, and federal agency personnel; energy efficiency program planners, operators, and evaluators; policymakers; NGOs; and consultants.
