1774 - How Green Codes Are Getting Smarter, Less Confusing–and Replacing LEED: An Overview of the new ASHRAE/ASHE Standard 189.3

Mar 14, 2017 3:00pm ‐ Mar 14, 2017 4:00pm

Credits: None available.

Standard: $30.00


This session provides an overview of the newly created ASHRAE/ASHE Standard 189.3: Design, Construction and Operation of Sustainable High Performance Health Care Facilities, which prescribes the procedures, methods, and documentation requirements for the design, construction, and operation of high performance sustainable health care facilities. The session covers how this standard relates to ANSI/ASHRAE/USGBC/IES Standard 189.1 and the upcoming revisions to the International Green Construction Code (IgCC). With the recent implementation of the new LEED V.4, numerous jurisdictions are evaluating the adoption of the IgCC to provide an alternative to LEED.

Learning Objectives:

  • Discuss the components and structure of ASHRAE Standard 189.3
  • Describe the impact of ASHE's co-sponsorship on the requirements of ASHRAE Standard 189.3
  • List the differences between Standard 189.1 and Standard 189.3
  • Explain how the IgCC code will impact LEED, and how Standard 189.3 may alleviate the design challenges of green code applications for health care facilities.

This session was very informative - All presenters were well versed in the content and were engaging. I appreciate the efforts put forth. Good overview of the current code status and Green codes in general. I guess the overall goal of LEED should be to create it's own obsolescence?
