The DOE, AHRI asserts, did not follow proper protocol when promulgating the WICF final rule and issued energy-conservation standards that many in the industry feel are unfair, not technologically feasible, and unnecessarily burdensome to HVACR manufacturers.
A fourth version of ASHRAE’s proposed legionellosis standard is open for public comment until Nov. 10, 2014. Standard 188P, Legionellosis: Risk Management for Building Water Systems, currently under development, will establish minimum legionellosis risk management requirements for building water systems.
The U.S. Department of Energy (DOE) has issued a ruling that establishes the 2013 standard as the commercial building reference standard for state building energy codes.
The discussion will focus solely on the mechanics of measuring the relevant values and the downstream calculations needed to rate the efficiency of WICF refrigeration system basic models that are either sold as mixed or matched systems.
To help battle Legionellosis, which includes both Legionnaires’ disease and Pontiac Fever, ASHRAE is currently developing Standard 188P: “Legionellosis: Risk Management for Building Water Systems.” The fourth public review draft of the standard is expected to be approved and made available for public comment soon.
A survey by Emerson Climate Technologies Inc. found that 40 percent of commercial contractors and 42 percent of residential contractors in the Northern region foresee upsell opportunities, while only approximately 30 percent of residential contractors in the South and Southwest look forward to higher revenue or higher margins.
The group’s amendment would allow GHPs to be compared to 80 percent efficient natural gas furnaces; include the desuperheater water heating efficiencies of GHPs; recognize the true cost of air-source heat pumps; raise the average by 54 percent; and extend the useful life of a GHP from 18 to 25 years.
