Hi, I’m working on a High-rise residential LEED energy modeling project now. I have a question regarding the lighting. I’m using Energypro, and found out the lighting saving is zero from the...

I've been trying to understand how does LEED treat kitchen exhaust hoods with make up unit(heating only) in the energy model. Is it process or non-process? The LEED reference guide 2009 v3,...

ASHRAE 90.1-2007 Appendix G states for baseline system types: "For laboratory spaces with a minimum of 5000 cfm of exhaust, use system type 5 or 7 that reduce the exhaust and makeup air volume to...

For EAp2/EAc1, what specific documentation does...

Under ASHRAE 90.1 - G3.1.1 do I HAVE to use exception C for any zones having special pressurization relationships, cross contamination requirements, or code-required minimum circulation rates? In...

I would like to get some feedback on how you all are interpreting Exceptions (c) and (d) under 90.1-2007 G3.1.1 Baseline HVAC System Type and Description. I have heard and seen differing...

We've got an 11,000 square foot maintenance garage for trucks, modeling it under LEED and ASHRAE 90.1-2007. This is a tricky space.

It has more than 15 BTUH/SFT of heat so according to...

I remember seeing from somewhere that if the exhaust fan is not interlocked with the HVAC, it should be considered a process load and modeled the same in proposed and baseline. Could someone...

Hi Guys,
I am a energy simulation engineer. Now I have a project which uses the district steam supplied by the local government as heat source.
I did the energy modeling based...
