Check out the Case 2 definition on page 95 of the 2009 Reference Guide. Rate and quantity are both clearly required there and I expect this is the standard to which your submittal will be held.

Thanks Amy. Strange that it's not on the requirements page though. There the rate is clearly ommitted. This should be corrected in the next addenda hopefully.

This stems from historical LEED-CS 2.0 submittal template for example...where for option 2 only the quantity is required. This is unfortunately still the case in LEEDv3 LEEDonline submittal form still only requires the volume for case 2...that's why I asked.

Hi there! Apologies for reawakening a 5 year old conversation but I had a query that was similar to the above conversation. Under case 2, I have calculated both the volume of captured runoff and drawdown rate for my project as per equations 1 & 2 in the reference guide (I also used the cheyenne botanic example as a reference point and everything looks good on my calculations). However, the LEED form seems to only require the percent reduction from runoff quantity (cf/storm). Is there some sort of formula that I have missed out on? Thanks in advance for any guidance provided!

Hi Sheena! You should check that you have the latest version of the form. If not, request it through the web.
