2024 Hot Water Forum & Hot Air Forum

March 12 - 14, 2024

    Hilton Atlanta | Atlanta, GA

    The 2024 Hot Water Forum (HWF) is the premier technical conference dedicated to efficiently producing, distributing, using, and reusing hot water. Since its inception in 2008, this two-day conference has brought together seasoned experts and newcomers to exchange knowledge, foster innovation, and help drive market transformation.

    In addition, ACEEE presented the second Hot Air Forum (HAF) in 2024, focusing on decarbonizing space heating in buildings of all kinds through heat pumps. Both conferences explored how these industries can reduce greenhouse gas emissions, improve grid resilience, and center equity.

    Previous HWF/HAF gatherings have attracted diverse attendees, including equipment and component manufacturers; water, gas, and electric utility professionals; and local, state, and federal agency representatives. Energy efficiency program planners, operators, evaluators, electricians, plumbers, installers, policymakers, representatives from NGOs, engineers, consultants, and other experts have found value in the sessions and great networking at the events.

    Ensuring Equity in Household Weatherization and Electrification | Wednesday Lunch Keynote, March 13 (12:30 – 1:30 p.m.)


    We heard from the Honorable Stacey Abrams, senior counsel for Rewiring America, former gubernatorial candidate, and former minority leader of the Georgia House of Representatives. 

    Weatherization and electrification are key to decarbonizing buildings, and will lower bills and improve health, safety, and comfort. But we must ensure low-income and disadvantaged communities are part of the clean energy transition.
