variable shading coefficient (SC), as with automated blinds and such, then the
answer is also yes – via creating a custom shading schedule.<o:p></o:p></span></p>

<p class=MsoNormal>Hi,<br>
am a eQuest newbie, am doing some research wherein i need to know the solar
gain factor the windows use, also does eQuest take into account Alternating
Solar Gain Factor???I would also like to find out whether variable infiltration
flow rates (or variable ventilation values) are taken into account??? the
hourly report block i generated only gave me same value for infiltration flow
rates for all 24 hrs & for all 365 days.<br>
<br>
Please help, this is regarding my Major Project at College & deadlines are
approaching.<br>
<br>
Thanks in advance,<br>
<br>
Regards,<br>
Piyush Varma <o:p></o:p></p>
