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.”
<p>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.</p>
<p>The current Standard contains 11 modeling cycles covering many
building energy modeling activities that occur over the life cycle
of a building:<br>
</p>
<ul>
<li>Simple box modeling</li>
<li>Conceptual design modeling</li>
<li>Load reduction modeling</li>
<li>HVAC system selection modeling</li>
<li>Design refinement</li>
<li>Design integration and optimization</li>
<li>Energy simulation aided value engineering</li>
<li>As-designed energy performance</li>
<li>Change orders</li>
<li>As-built energy performance</li>
<li>Postoccupancy energy performance comparison</li>
</ul>
<p></p>
<p>Some of the changes that the committee may consider to increase
the Standard’s adoption and utility are:<br>
</p>
<ul>
<li>Adding new modeling cycles</li>
<li>Including multiple tiers of compliance</li>
<li>Adding details and examples for each modeling cycle</li>
<li>Including options based on project size, type, and scope</li>
<li>Including analysis other than whole-building energy analysis</li>
<li>Reporting of carbon emission</li>
<li>Adding support for residential modeling</li>
<li>Restructuring the requirement for modeling credentials to be
more inclusive</li>
<li>Aligning with industry performance tracking</li>
<li>Adding example scope of work referencing language</li>
</ul>
<p>Other suggestions are also welcomed.</p>
<p>If you are interested in helping to improve Standard 209 and<br>
</p>
<ul>
<li>you use building energy modeling to perform any of the
modeling cycles</li>
<li>your organization either currently does or could reference the
Standard</li>
<li>you specify building energy modeling services</li>
</ul>
<p>please consider helping. Candidates to participate in the
revision process may apply for one of three possible roles:<br>
</p>
<ul>
<li>Voting members</li>
<li>Non-voting members</li>
<li>Interested participants</li>
</ul>
<p>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:</p>
<blockquote>
<p><a class="moz-txt-link-freetext" href="http://www.ashrae.org/pcmemberapp">http://www.ashrae.org/pcmemberapp</a></p>
</blockquote>
<p>There are a limited number of voting members, so some may be
accepted as non-voting members.</p>
<p>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:</p>
