Hi Everybody,
I intended to meet SS 7.1 Heat Island Effect - Nonroof via Option 2 by covering all car parking spaces in vegetative shade.
On closer examination of the project definiton for this option I note that covered parking is defined as 'parking underground, under deck, under roof, or under building'. The shade from the vegetation will still count towards Option 1 but the large amount of unshaded roadway on the site makes this compliance path look unlikey.
Has anywone heard of structural shade not mentioned in the covered parking definition, such as canvas sheeting, providing compliance for this credit?
Also - what are people's thoughts on the combination of structural, such as a wooden trellis, and vegetation providing shading for Option 2 of the credit.
Thanks - Francis

This is similar to my case above...can't wait to see how other people reply.

This seems fine to me. Regarding architectural devices such as canvas, there is a provision for that in the credit language already, and they have to have an SRI greater than 29. You can pursue a combination of measures. Regarding the wooden trellises with vegetation grown on them, this is a little out of the ordinary, but as long as you can prove that it's basically equivalent or better than shade provided by a tree, I would anticipate getting approval. Showing this might be tricky, though, and I would think it through carefully.

An additional question that I have on these issue is that, for example, If I include shading from trees to be grown in the next 5 years, can I include them in the energy model to gain more credits for EAC1?
Thanks in advance

Francis & Jean (& any others),
Where did your projects end up? Were you able to claim canvas covers and/or vegetation under Option 2 as a way of placing car spaces under cover? Or were you only able to claim them under Option 1 as a way of shading hardscape?
Cheers,
Tim

Tim,
As long as you are meeting the credit requirements by a vegetated roof or a roof with an SRI value of atleast 29 for 50% undercover parking spaces, you should be fine. If you are using the techniques you described for specifically parking slots they will be under option 2. But if you use them as an exterior structure for other areas not intended for parking spaces (i.e. any hardscape area on site), they will fall under option 1.
Hope this helps.

Hi Saud,
Really the problem is the word "roof"! What we're really looking at is a fabric shading canopy for each individual car space, which would have SRI>29. Have you (or any others) successfully used something that really is not a "roof" under Option 2?
Cheers,
Tim

Hi Tim,
I can see how this is making confusion. Although I haven't myself use such a strategy but from what you are describing the fabric canopy is used to "shade" the car space and it will have an SRI of >29. The requirement of the credit is to actually shade or under cover 50% of the parking spaces while providing an SRI of 29 etc. Also on leedonline when filling the credit form, the form does not ask about the "roof" type. Rather you have to input a description of the material's SRI. Option 2 Parking Under Cover on leedonline has further two options. One states: "Reflective Materials. The project includes parking that is shaded or covered by materials with an SRI of at least 29". So in my opinion the fabric canopy should qualify as it is meeting the requirements of the credit.
