This is a recording of an SF Bay Area Chapter event, held on August 15, 2018 at DPR Construction in San Francisco, CA.

See the presentation slides here.

The presentation provides an overview the new ASHRAE Standard 209, Building Simulation Aided Design. The presentation also tells the story of how the standard came to be, following a generation of mixed success by energy modelers who were trying to make an impact. The talk includes extra focus on requirements in the standard that may present challenges to some energy modelers, and some keys to successful implementation.

The presentation was followed by a discussion on some of these challenges and best practices that attendees have used to address them. Example challenges include obtaining information from design teams and requirements for quick turnaround to meet project timelines.
