SRI of wood?

I have a project with wood (not composite wood) deck areas. How does one determine the SRI of the wood? Is there a default value available for light, medium, or dark wood?

EH, I haven't worked on a project that has deck areas, so I'm not quite sure how to determine the SRI of wood. Sorry.

Hi EH, I have the same problem with the terrace of my project. Did you find some information about the default value of SRI available for light, medium, or dark wood? Thanks in advance for your help

No insight here yet? I have a potentially huge portion of a harbor walk and marina dock in my project boundary that could be wood, and am wondering how to treat it in terms of reflectivity. I will be counting it as hardscape.

From the web site I found linked below it looks like wood shingles have a 21.9 SRI. Some were tested with a tinted coating which maybe another question for your project. If you search the word "wood" at the link below, you'll see what I found. Hope this helps, it seems like there should be more on this somewhere! http://www.fsec.ucf.edu/en/publications/html/fsec-cr-670-00/

Hi Emily Reese, we just had a answer from a laboratory about the wood in our terrase that SRI = 38. This is a RED_Balau_Wood with a natural color that the manufacturer and architect defined as a Light-Colored. The natural color of this kind of wood is more light with the time. The next week we have a answer from the Review about this Credit and than I can tell you more information about. But I know that if you using for your project a similar wood like our wood, you can use this value for SRI and you have need to explane why they are similar.

Ok, thanks, y'all! Ermal, please do let us know what the reviewers say when you get a chance.

Hi Emily, yes the review accepted our value of SRi about the wood and we achieved this credit. We used the excel-tools "SSc7.2_Weighted Calc-1.xlsx" to calculate the mix area of our roof (green, wood, gravel and concrete) that you find on line at the follow link: http://www.leeduser.com/credit/nc-2009/ssc7.2#doc-tab See the calculator in LEEDuser's Documentation Toolkit. If you have need for other informations, let me know about. Ermal
