LEED 2009 for New Construct, Optimize Energy Perform- EA CR 1

NC-2009 EAc1: Optimize Energy Performance
posted by John Harrington on Jul 29, 2011, 11:30 am

I have two buidings on the same site/project boundry.

Do I model the two buildings as one building? If I did two seperate models I am not sure how I would show this on the LEED Credit...

Landscape lighting

NC-2009 EAc1: Optimize Energy Performance
posted by Julien Daclin on Sep 13, 2011, 1:46 pm

Appendix G (Table 3.1) states that lighting power for building facades has to be modeled in the energy simulation. However, it is not clear if landscape lighting should also be taken into account...

I am going to be modeling a building that plans on buying landfill gas to burn in boilers which will contribute to EAc2.

I know I can double-dip on EAc1 and EAc2, so do I need to include...

Modeling PCW Heat Rejection for DES vs. System 5 (DX Cooling)

NC-2009 EAc1: Optimize Energy Performance
posted by Evelyn Dicks, EI, CxA on Jul 31, 2011, 1:14 pm

I am working on a building that supplies process cooling water (PCW) to lab spaces. The PCW rejects its heat through a heat exchanger to the chilled water system from a district energy plant....

Question:
Does the HVAC system for the baseline have to be the same type as the proposed design HVAC equipment?
(ie. could you use a...
