SR Values for Paving

Hi, Under LEED V4, if the manufacturer can not provide the SR value for paving can we use standard SR values based on the colour of the paving? Or to comply under V4 must we have specific manufacturer information? Thank you!

Under v4 project teams must provide manufacturer documentation or independent testing demonstrating SRI value for roofing material and SR value for nonroof material. Typical SR values can be used for standard nonroof materials per LEED Interpretation 10411. If independent testing is required, page 6 of the Cool Roof Rating Council Standard (CRRC-1) (http://coolroofs.org/documents/CRRC-1_Program_Manual_-_2015-11-19_Final.pdf) outlines the test methodology and number of tests required for different nonroof materials.

HI Summer, Thank you for your response, however, it has raised further questions for me. If the non-roof materials do not fall under the categories outlined within the LEED Interpretation 104411 must we seek manufacturer documentation confirming the SR values? We are having great difficulty in sourcing any SR values from manufacturers. Under V4 for International projects we can refer to the Cool Roof Council for similar materials however this does not cover non roof materials. Would we be ok to use comparative figures for non-roof materials as was allowed in V3? Thank you

Based on GBCI reviewer comments for a current LEEDv4 project, my understanding is that they are looking for at minimum one of the following: manufacturer documentation of the nonroof material SR value, utilization of the typical SR values for standard nonroof materials per LEED Interpretation 10411, or an independent testing report showing the tested SR value. For example, we had our concrete paving material third-party tested and submitted the report to GBCI as documentation. As to your second question, I can't answer that one. But if your project is registered under LEEDv4 you should have been assigned a LEED coach who may be able to assist with international compliance questions.

Hi Francis, We are facing the same situation now. How did you solve this problem? Did you get any feedback from your LEED Reviewer? Thanks,
