<div dir="ltr"><div><div>Chris,<br></div><div><br>Well, though I contribute to the project, I only do so as a user (when I find problems I fix them, and when I do might as well make a pull request so that it's fixed for everyone). I'm in no way in charge of it (NREL is, with help of Canada's NRC), <b>so anything below is my own opinion only</b>. Also worth mentioning that<b> I've mostly played with (much) earlier versions</b> of 
openstudio-standards too (v0.1.4 might be the last I used on a real-life project, 
today's version is v0.1.11!)<br><br>I've successfully used openstudio-standards to generate a baseline for several of my real-life projects. But so far I always had to modify the code to make it work, which was slightly annoying for me but great for the openstudio-standards project since it meant it got tested it on real, complex projects and uncovered some new cases and bugs that got fixed (eg: high-rise buildings that qualify for several exceptions because portions were residential, other were commercial, and each had secondary areas served by other type of fuel...). <br><br>Even though it required me to fiddle with the code, I found it to achieve two things: a speed improvement anyway, and a much higher quality baseline (for example the system exceptions based on the load difference and/or different operating hours are very hard to do correctly and fully "by hand", especially when you have 100 zones).<br></div><div><br></div>Since OpenStudio 1.13, the openstudio-standards is part of the OpenStudio package itself, proof that it is deemed to be bug-free enough to be released to the public. That doesn't mean you aren't going to hit a bug, or simply get an error that you'll have to troubleshoot with an error message that might not be crystal clear and will require you to dig a bit in the source code - or get someone else to do it (eg <a href="https://unmethours.com/question/22914/openstudio-baseline-building-measure-error/">this question</a> asked 5 hours ago). But this should happen less and less often as bugs and new cases are uncovered as the user base grows (assuming users, who have rights and duties, do the right thing and open issues when they find them).<br>The openstudio standards is still under active development (see <a href="https://github.com/NREL/openstudio-standards/releases">https://github.com/NREL/openstudio-standards/releases</a> if you need convincing).<br><br></div><div>Worth mentioning that even if one day it becomes "perfect" (it's getting quite close to it), it will never mean a user can just switch their brain off, click a button, and voilà! You'll still be responsible to ensure that it worked correctly. Plus, the baseline determination uses inputs that are in the proposed model: you have to properly assign space types, and proposed HVAC systems (including fuel used, etc). If you screw that up, the baseline will be wrong. As usual, the one rule is GIGO.<br><br></div><div>Cheers,<br></div><div>Julien<br></div><div><br><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div>--<br>Julien Marrec, EBCP, BPI MFBA<br>Energy&Sustainability Engineer<br>T: +33 6 95 14 42 13<br><span style="color:rgb(0,0,0)"><br></span><span style="color:rgb(0,0,0)">LinkedIn (<a href="https://www.linkedin.com/in/julienmarrec" target="_blank">en</a>)<span style="color:rgb(0,0,0)"> <i>| </i></span>(<a href="https://fr.linkedin.com/in/julienmarrec/fr" target="_blank">fr</a>) : </span><br><span style="color:rgb(0,0,0)"><a href="http://www.linkedin.com/in/julienmarrec" target="_blank"></a></span></div></div></div></div></div></div>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">However, it seems to me that I could also assign System 5 to the retail spaces. The non-denominate space (retail) is larger than 20,000 ft2 and the building

 would not be an apples-to-apples comparison. The proposed design has packaged single zone systems serving the retail spaces making tenant sub-metering simpler.
