[Equest-users] Light Shelves

[Nick Caton]

So far as solar loads are concerned, overhangs can be a fine
representation, as can building shades.  Explore your chosen approach to
best capture what you're trying to emulate.

 

It might be a fallacy to ignore the effects of daylighting controls
however on your HVAC design, however.  If you reduce your lighting loads
by a significant fraction - there are potentially significant effects on
your HVAC system behavior.

 

As a caution, the rabbit hole goes deep... best of luck =)!

Subject: [Equest-users] Light Shelves

 

I looked through the archives and saw some discussions with this topic,
but wanted to ask the questions again.  I need to model light shelves
for the aspect of reducing HVAC equipment size, with no regard to the
daylighting, as of right now. This will be an issue, but i just want to
see the difference in the HVAC sizes.  Is the correct way to apply the
light shelves to use an over hang in the window properties? or should i
use a shading schedule? or should i use a building shade?  My first
guess would be over hang, but i haven't used these for this reason, so i
wanted input from others.

 

Thanks,
