Is is possible to exempt 10% of the floor area that has CFC/halon/etc containing fire suppression systems? This project has several restaurants that together constitute less than 10% of the floor...

My understanding is that the minimum acceptable Leakage Rate is 0.5%, even if the actual data demonstrate a lower leakage rate. The v4 form accommodated this by allowing the Lr to be manually...

A building earned enhanced refrigerant management for LEED NC but had to add one unit during the performance period due to theft. I'm sure the existing units have probably had refrigerant added...

Ben Stanley Senior Sustainability Manager WSP- Built Ecology LEEDuser Expert 250 thumbs up November 30, 2015- 5:53 pm Hi Norbert, Did you ever get solid guidance for these issues outside of this forum? For point 1, if the old compressor was decommissioned prior to the performance period, then it could be excluded from the calculation entirely. If not, include it and determine the leakage rate per...

I'm wondering what performance period would be acceptable for calculating the leakage rate (lbs of refrigerant added and over what time frame) for this credit. For instance, does the period over...

The end of life refrigerant loss (MR) has a range of 2%-10%. The reference guide says I can use a lower than the 10% default rate if I can demonstrate how the lower rate is justified. How would...

Since there has been some discussion on this topic on this forum before, I wanted to make sure everyone is aware of the 11/1/11 LEED addendum stating that "If new equipment is being installed,...

Our supplier who does the recharging of refrigerants has a standard formula for determining the refrigerant charge based on minutes per day of purge pump out operation. The values end up being...

90% of the AC equipment at my building has been replaced in the past 2 years. None of that equipment has had refrigerant recharges. How would I go about entering a leakage rate if we have yet...

Could someone please confirm the guidance and documentation for projects connected to a third party district chilled water loop? Does the utility (chilled water provider) have to provide any...
