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.</p>
<p>Please provide any contact info and details if you can.</p>
<p>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.</p>
<p>THANKS for being LEEDers!!</p>

Thanks for your reply. <br>
<br>
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? <br>
<br>
Thank you.<br>
<br>
