[Equest-users] Attic insulation

[Charles Hoes]

Hi

I seem to be a complete novice with eQuest because of how basic this 
question is.  I am modeling a simple, one story building on a slab. The 
building has flat, 8' ceilings and a pitched roof.  There is a sheet 
rock ceiling, with blown insulation on top of that, then an "attic 
space" covered with a roof.

It seems logical that the "Top Floor Ceiling (below attic)" fields would 
apply to the ceilings.  It also seems logical that the type of 
insulation would apply to the blown in insulation on top of the ceiling.

When I run the simulation, I expect the "LS-A Space Peak Load Summary" 
to give me a summary of the space peak loads and the building peak 
loads.  However, while it looks like it does this, it does not include 
the ceilings.  It gives the same answer no matter what I do with the 
insulation values as noted in the previous paragraph.  It is as if the 
ceiling is totally ignored.  LS-C shows the same peak values as LS-A.

I have noticed that a report called SS-D Building Load Summary also 
gives something that looks like building peak loads, but it is a little 
higher than those provided in LS-A and LS-C.  It does change when I 
change the ceiling insulation.

My quandary has to do with if LS-A and LS-C do not give a summary of the 
space peak loads, what do they represent.  I also wonder if SS-D will 
give what is sometimes called the "district" heating loads (the loads 
that are required to maintain the temperature set points without regard 
to the details of the HVAC system).

Any help is understanding these reports, and why LS-A and LS-C does not 
reflect the ceiling insulation while SS-D appears to.

Thanks
