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.

Despite coming from humble beginnings and not having air conditioning as a kid, Wilkins became one of the most respected voices in the HVAC industry.

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.

The rule deems certain HFC refrigerants unacceptable in specific applications on or after Jan. 1, 2016. 

The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) has announced an American National Standards Institute (ANSI) public review period for Addendum E to ANSI/ACCA 2 Manual J - 2011.

The goal is to create a comprehensive framework for jurisdictions looking to implement and adopt green building regulations and codes and/or provide incentives for voluntary leadership programs such as LEED.
