[Bldg-sim] ASHRAE Seeks Users and Adopters to Revise Standard 209 “Energy Simulation Aided Design for Buildings Except Low-Rise Residential Buildings”

[Jason Glazer]

Building energy modelers, architects, and high-performance 
building incentive program organizers to are needed to help 
update ASHRAE Standard 209, first published in 2018. The 
purpose of Standard 209 is to “define minimum requirements 
for providing energy design assistance using building energy 
simulation and analysis.”

The Standard has been referenced by AIA, USGBC, ASHRAE, 
IBPSA-USA, the University of Virginia, BuildingGreen, 
Washington State, and by individual architecture firms 
seeking modeling services. Many of these references are 
informational. The update to the Standard should strengthen 
these existing references and make it easier for it to be 
adopted by other organizations.

The current Standard contains 11 modeling cycles covering 
many building energy modeling activities that occur over the 
life cycle of a building:

  * Simple box modeling
  * Conceptual design modeling
  * Load reduction modeling
  * HVAC system selection modeling
  * Design refinement
  * Design integration and optimization
  * Energy simulation aided value engineering
  * As-designed energy performance
  * Change orders
  * As-built energy performance
  * Postoccupancy energy performance comparison

Some of the changes that the committee may consider to 
increase the Standard’s adoption and utility are:

  * Adding new modeling cycles
  * Including multiple tiers of compliance
  * Adding details and examples for each modeling cycle
  * Including options based on project size, type, and scope
  * Including analysis other than whole-building energy analysis
  * Reporting of carbon emission
  * Adding support for residential modeling
  * Restructuring the requirement for modeling credentials
    to be more inclusive
  * Aligning with industry performance tracking
  * Adding example scope of work referencing language

Other suggestions are also welcomed.

If you are interested in helping to improve Standard 209 and

  * you use building energy modeling to perform any of the
    modeling cycles
  * your organization either currently does or could
    reference the Standard
  * you specify building energy modeling services

please consider helping. Candidates to participate in the 
revision process may apply for one of three possible roles:

  * Voting members
  * Non-voting members
  * Interested participants

The voting and non-voting members will directly update the 
document by forming topical workgroups. Voting members count 
toward the committee’s quorum so planning to participate in 
all full committee meetings is important. Voting and 
non-voting members should apply to ASHRAE at the following link:

    http://www.ashrae.org/pcmemberapp

There are a limited number of voting members, so some may be 
accepted as non-voting members.

Interested participants are encouraged to attend and 
participate in meetings, will be surveyed for determination 
of priorities, and may only comment on documents when they 
are available for public review. If you want to be an 
interested participant, please send an email to me at:

Thank you,

Jason
