ASHRAE/ASHE标准189.3规定了高性能、可持续卫生保健设施的设计、施工和运行的程序、方法和文件要求。本标准以标准189.1的工作为基础，旨在解决医疗设施的可持续性问题，并为高性能建筑的设计提供了医疗行业的视角。标准的2021版的变化反映了两个显著的发展:FGI指南的2018个分离为三个出版物，并且增加了对1891-2020标准的管辖权选项。

ASHRAE/ASHE Standard 189.3 prescribes procedures, methods, and documentation requirements for the design, construction, and operation of high-performance, sustainable health care facilities.This standard builds on the work of Standard 189.1 to address sustainability in health care facilities and provides a health care sector perspective to the design of high-performance buildings.Changes to the 2021 edition of the standard reflect two significant developments: the 2018 separation of the FGI Guidelines into three publications, and the addition of jurisdictional options to Standard 189.1-2020.
