[Bldg-sim] LEED-NC v2.2 innovation in design credit for reduction in peak energy load

[Robert Gengelbach]

Reduction in energy relates directly to  EAc1 and can be accounted for in that credit.  No ID credit would be available for reducing peak load.

RE: innovation in design credit for reduction in peak energy load


 

Has anyone applied for and/ or gotten an innovation in design credit for reduction in peak energy load for any version of LEED? We're working on a project under LEED NC v2.2 and have significant reduction in lighting load during peak hours by using solatubes.

Please provide any contact info and details if you can.

I appreciate the assistance. It seems like the energy model can be manipulated to show the project savings during peak times and that would be enough information needed for a submittal to the GBCI.

THANKS for being LEEDers!!

Demba and Vikram,

Alright. Thanks for the clarification.

Exhaust fan power is to be the same for both designs. You apportion the remaining baseline fan power allowance between supply and return/relief.

Vikram,

Thanks for your reply. 

So, does it mean I will have to model the exhaust fan in the baseline model but in a fashion such that it consumes power proportionate to your proposed design (supply, return and exhaust) but falls within the Allowable Fan System bhp value of Appendix G. Am I right? 

Thank you.

Regards,
Vinay

I'm pretty sure that your fan power allowance in 90.1 is for all fan energy (including exhaust). So for example if your baseline fan allowance is 20kW (hypothetical), you will need to apportion that allowance between supply and exhaust similar to your designed building. 

 

There was an extensive discussion about this around a year ago on this list (check the archives).

Vinay, 

 

It is required to also model the exhaust fans in the Baseline. Use same cfm and fan powers as in the Proposed.

Hello All,

Do we have to model the exhaust fans also according to Appendix G for a Baseline model?
If yes, how should we design the cfm?

Thank you very much.

Regards,
Vinay
