[Bldg-sim] natural ventilation

[Karen Walkerman]

Hello all,

I have just created a trial project using natural ventilation in eQuest.  I
have 5% openable area to the net floor area. I multiplied by 0.6 (for total
vent area fraction) I end up with 0.3 for my total vent area fraction.

When compared to a system using the "air-change" method for natural
ventilation, the heating energy is approximately equal when "0.18" air
changes is specified.  However, the cooling energy increases by a factor of
6.  Also, this 0.18 air changes per hour is only 65% of what would be
required if 62.1 were used.

Has anyone used the S-G method for natural ventilation successfully?  Any
thoughts on the above observations?

Thanks,
