Efficient electric water heaters in multifamily buildings significantly reduce carbon emissions

In buildings with 5+ units, water heating uses more energy than space heating, cooling, or lighting.

Efficient electric hot water heating technologies significantly reduce the carbon emissions of multifamily buildings, according to a report by the American Council for an Energy-Efficient Economy (ACEEE) and New Buildings Institute (NBI).

In multifamily buildings with five or more units, water heating uses more energy than space heating, cooling, or lighting, the report says. Converting gas-fired water heaters to advanced technology—electric heat pump water heaters (HPWHs)—would cut greenhouse gas emissions from water heating by an average of 58%.

If HPWHs are powered entirely by clean sources, they cause zero emissions, making them a critical tool for decarbonizing the economy. Efficient electric water heaters carry a higher upfront cost over gas models, so policymakers would have to provide incentives to owners to make the conversion, the report says.

“Many utilities offer incentives for building or unit owners to install in-unit heat pump hot water heaters,” an ACEEE/NBI news release says. “Yet few programs are designed specifically for multifamily buildings, which offer unique challenges.”

EPA Says Additional Lead Paint Cleaning Rules Not Necessary

The EPA has concluded that current Lead: Renovation, Repair, and Painting Program (LRRP) cleaning requirements and lead-safe work regulations are sufficient to protect the public from lead dust hazards. “Our members have been instrumental in contacting legislators to detail the detrimental impact of the current LRRP," says Richard Walker, American Architectural Manufacturers Association’s president and CEO. “This collective industry voice has prompted the EPA to make the responsible decision to refrain from adding further, unnecessary costs to homeowners under the current economic climate."http://www.aamanet.org/news/1/10/0/all/603/aama-commends-its-members-congress-for-vacating-lrrp-clearance-rule
