I am documenting an energy model for LEED 2009 EAp2/EAc1 and I would like to include a document that describes the modeling techniques used for each modeled system.

Dear All we have model the factory project with 50% A/c and 50% Ventilation and the fresh air is supplied by ERV, HRW, Treated fresh air units to A/c areas but the ERV, HRW, Treated fresh air unit

I am working on a project in the UK and the client wants to know what the alternatives are to ASHRAE 90.1 for energy modelling to demonstrate compliance with EAp2 and EAc1.

Our LEED-NC v2009 project (which has the v06 EAp2/EAc1 LEED Credit Form) is attempting to utilize the new required excel calculator and following Option 1 (http://www.usgbc.org/resources/minimum-en

Regarding what is taken as a process energy.

Greetings, ASHRAE 62.1-2007 establishes a ventilation exhaust rate for garages of 0.7 cfm/sq.ft. Our project has lower rate and besides it applies a CO control settings of 20mg/m3. The question is:

I have a job where there are several Big Ass Fans. My problem is in determining how to model them in the energy simulation.

The project comprises four hospital buildings, called B, C, D and E, and each building is registered as an individual project on a campus basis.

Hello. I’m dealing with the calculation method for the credits relative to EA section. I don’t understand the meaning of the following sentence of paragraph G2.4 of ANSI/ASHRAE/IESNA STANDARD
