Hi, In LEED v2009 BD+C Sustainable Sites Credit 7.1 there is a table with solar reflectance index for standard paving materials, where the typical new gray concrete is 35.

Can an underground building, with an insulated roof and 24inches of fill and turf on top, qualify for a vegetated roof in NC-v4, SSc5?

Hi, 

I have seen a couple posts about how to count gravel in a nonroof measure. However, I am wondering if gravel counts in the "Total site paving area" of the calculation. 

Do products that have UL Greenguard Gold certification meet the requirements for Products & Materials?

Hi all,

Hello,

HI All,

Good afternoon everyone,

Hello, Under EAc1 my understanding is that the energy model will use a baseline assumption for plug loads.

Has anyone ever gotten or heard about a plug load exemption for projects that demonstrate energy savings but due to extreme plug loads (over 60%) cannot meet the prerequisite 10%?
