The paper first reviews the standard, then compares the standard with ASHRAE Standard 90.1-2004 to identify discrepancies in code coverage and stringency, and recommends some energy conservation measures that can be evaluated in the design of public buildings to achieve energy savings beyond the standard. The paper also highlights several important features of 90.1-2004 that may be considered as additions to the GB50189-2005 standard during the next revision. At the end the paper summarizes the latest developments in building energy standards and rating systems in China and the US.</p>10aASHRAE 90.110abuilding energy standard10aChina10acommercial buildings10aenergy efficiency10agb50189-20051 aHong, Tianzhen  uhttps://simulationresearch.lbl.gov/publications/close-look-china-design-standard
