Decoding the Energy Codes: 2019 ASHRAE code aims to simplify compliance

摘要

LATE LAST YEAR, ASHRAE, the American Society of Heating, Refrigerating and Air-Conditioning Engineers, published the 2019 version of ASHRAE/ANSI/IES 90.1, "Energy Standard for Buildings Except Low-Rise Residential Buildings," the model commercial building energy code. For lighting, the new version most notably modifies interior power allowances, updates some control requirements and provides contractors a new simplified compliance method for office, school and retail buildings. Commercial building energy codes regulate the designed energy efficiency of nonresidential buildings.
