Dear All, In my project I am trying to reduce energy consumption, I am using LED lights, high efficient air cooled units (baseline is water cooled chillers). The building already is underground bu

This is a V4 doubt but I cant imagine anyone is monitoring the V4 forum so i decided that posting it here would be more effective. Does anyone know wether or not evaporator input power should be i

I am not sure that I am interpreting section G3.1.3.14 in the correct way.

Hello, I am wondering if it is allowed to add additional exhaust fans into the proposed model to extract more hot air from the zone and save more energy on cooling. Is this possible?

Dear All, I am working on a project where the base case is packaged single zone and proposed case has split units. The unmet hours in proposed case is less than 300hours in each zone.

do we have any area requirement for energy modeling i.e. Minimum area to opt for Option 1 Whole building energy modeling aproach for EAP2?

Hi All, I am working on a LEED NC 2009 project and have questions about filling up the v2009_Minimum Energy Performance Calculator_v06. Hope someone can give me some advice.

This was posed in another spot on LEEDuser and I thought it was worth asking here. Is there a rule to use initial vs. long term R-values?

Does any body know how to set "Maximum Primary Air Flow Rate" ,"Maximum Secondary Air Flow Rate" ,"Minimum Primary Air Flow Fraction" and "Fan On Flow Fraction" in energyplus to meet G3.1.3.15 "--

The Bird's Eye View comments on this page indicate that the USGBC will allow projects to meet the 10% minimum energy performance threshold with onsite renewable energy.
