FAQs about SSc5 :

My project has a balcony that projects away from the building, and does not provide a roof to an enclosed space for the building. How should the balcony be treated for this credit?

Should we include motorcycle parking spaces in our total parking count for the Parking Under Cover option?

Projects that provide covered parking are eligible for points under this credit, but what if a project provides no parking?

What if I need to have a material tested?

Can I exclude functional usable areas like recreation courts or rooftop patios?

How should we account for off-site parking under this credit?

If the manufacturer cannot provide the SR or SRI values, can standard values be used based on the color of the material?

If the top floor of a parking garage includes parking spaces, is it considered a roof or non-roof surface?

In LEED v4, are there standard allowed SRI values for things like concrete, as in LEED 2009?

NC-v4 SSc5:Heat island reduction

SR Natural stone

Hello, About the option 1 Nonroof and Roof, we are using a natural Stone (local material), Off-White color, for the pavement in the main square and walkway. But the manufacturer can not provide the SR value for paving and the standard nonroof materials per LEED Interpretation 10411 either. Is there another reference about SR which includes this material or we must apply the testing?

Hi Juan. You are correct LEED Interpretation 10411 only provides typical solar reflectance values for gray cement concrete, white cement concrete and asphalt concrete. Cool Roof Rating Council (CRRC) does have a searchable product database you might try. http://coolroofs.org/products/results
