energy conservation program for certain industrial equipment energy conservation standards and test procedures for commercial heating air-conditioning and water-heating equipment 78 pages in english the u.s. department of energy doe is proposing to amend its energy conservation standards for several classes of commercial heating air-conditioning and water-heating equipment. pursuant to the energy policy and conservation act of 1975 epca as amended doe must assess whether the uniform national standards for these covered equipment need to be updated each time the corresponding industry standard--the american national standards institute ansi american society of heating refrigerating and air-conditioning engineers ashrae illuminating engineering society of north america iesna standard 90.1 ashrae standard 90.1 --is amended which most recently occurred on 29 october 2010. based upon its analysis of the energy savings potential of amended energy conservation standards and the lack of clear and convincing evidence to support more-stringent standards doe is proposing to adopt the amended standards in ashrae standard 90.1 for small large and very large water-cooled and evaporatively-cooled commercial package air conditioners variable refrigerant flow vrf water-source heat pumps less than 17 000 btu h vrf water-source heat pumps at or greater than 135 000 btu h and computer room air conditioners. doe is also proposing updates to the current federal test procedures to incorporate by reference the most current versions of the following relevant industry test procedures specified in ashrae standard 90.1 air-conditioning heating and refrigeration institute ahri 210 240 small commercial package air conditioning and heating equipment ahri 340 360 large and very large commercial package air conditioning and heating equipment underwriters laboratories ul 727 and ansi z21.47 commercial warm-air furnaces and ansi z21.10.3 commercial water heaters . furthermore doe is proposing to adopt ahri 1230 for newly-created classes of variable refrigerant flow air conditioners and heat pumps ashrae 127 for computer room air conditioners and ahri 390 for single package vertical air conditioners and single package vertical heat pumps. in addition doe is announcing a public meeting to receive comment on its proposal and related issues.
