The program is not designed to support calculations of the movement of<BR>air between zones. The outdoor air flow in the HVAC window is outdoor air<BR>introduced by the mechanical system and not through windows. I think you<BR>would be better off looking to another tool (maybe
EnergyPlus/OpenStudio?)<BR>that explicitly supports these calculations.<BR><BR>All the best,<BR>Dan<BR><BR><BR>-<BR>Daniel Knapp, PhD, P Phys, LEEDR AP O+M<BR><A href="mailto:danielk@arborus.ca" ymailto="mailto:danielk@arborus.ca">danielk@arborus.ca</A><BR><BR>Arborus Consulting<BR>Energy Strategies for the Built Environment <A href="http://www.arborus.ca/" target=_blank>http://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 2013-04-24, at 11:12 AM, noa@gbwawa <<A href="mailto:noa@gbwawa.com" ymailto="mailto:noa@gbwawa.com">noa@gbwawa.com</A>> wrote:<BR><BR>> Hi all,<BR>> <BR>> I just understood that e-Quest dosn't calculate natural ventilation<BR>without making some definitions.<BR>> I found that in the detailed mode, in the HVAC window, I can define the<BR>outdoor air flow, but how do I define what is the area of the window
