The ventilation load doesn't show up in any of the standard eQuest reports. This is because eQuest is based on DOE-2.2 which runs in sequence every hour as LOADS -> HVAC -> ECON. LOADS calculates the loads on every space in the building according to a constant indoor space temperature and the outdoor weather conditions and then passes this information to HVAC which uses it to calculate the required response from the systems. The load reporting comes out of LOADS before HVAC does its work. I recommend digging into the DOE-2.2 documentation for more information.<br><br>There is probably a way to separate out the ventilation load in the hourly reporting functions. It's something I'm looking into but haven't
figured out yet. Let me know if you find an easy way to do this. <br><br>All the best,<br>Dan<br><br><br>—<br>Daniel Knapp, PhD, P Phys, LEED® AP O+M<br><a rel="nofollow" ymailto="mailto:danielk@arborus.ca" target="_blank" href="mailto:danielk@arborus.ca">danielk@arborus.ca</a><br><br>Arborus Consulting<br>Energy Strategies for the Built Environment<br><a rel="nofollow" target="_blank" href="http://www.arborus.ca/">www.arborus.ca</a><br>76 Chamberlain Avenue <br>Ottawa, ON, K1S 1V9 <br>Phone: (613) 234-7178 ext. 113<br>Fax: (613) 234-0740<br><br><br><br><br>On 2013-05-21, at 1:13 PM, Mark Rasmussen <<a rel="nofollow" ymailto="mailto:markfrazz@yahoo.com" target="_blank" href="mailto:markfrazz@yahoo.com">markfrazz@yahoo.com</a>> wrote:<br><br>> To Whom May Be So Kind,<br>> <br>> We are currently creating an Energy Model using eQuest for LEED NC v2.2 <br>> for a facility that will consist of restaurants and a bar/lounge.
