{"abstract":"The U.S. Department of Energy (\"DOE\") is publishing a final rule to establish definitions for \"direct expansion-dedicated outdoor air systems\" (\"DX-DOASes\") and \"unitary dedicated outdoor air systems\" (\"unitary DOASes\"). Unitary DOASes are a category of small, large, and very large commercial package air conditioning and heating equipment under the Energy Policy and Conservation Act, as amended. In addition, DOE is establishing a test procedure to measure the energy efficiency of DX-DOASes, which aligns with the most recent version of the relevant industry consensus test standards for DX-DOASes, with certain minor modifications. Lastly, DOE is adopting supporting definitions, energy efficiency metrics for dehumidification and heating modes, and provisions governing public representations as part of this rulemaking.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF ENERGY","name":"Energy Department","id":136,"url":"https://www.federalregister.gov/agencies/energy-department","json_url":"https://www.federalregister.gov/api/v1/agencies/136","parent_id":null,"slug":"energy-department"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2022/07/27/2022-15493.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"429","title":10},{"chapter":null,"citation_url":null,"part":"431","title":10}],"citation":"87 FR 45164","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The effective date of this rule is August 26, 2022.
