Period & time of Breakdown

Hi Jeff The consumption should be based off of one year of energy data, and the total annual breakdown of consumption should be fairly close to what is represented in EAp2 as the total annual consumption for site energy use. Ideally, this breakdown would be completed using actual consumption data, using existing submetering and spot submetering where available, and performing engineering calculations to determine breakdown. Using a known database, such as CBECS, could be a good place to begin the process of developing the breakdown but in our experience, an acceptable breakdown needs to be supported by more detailed analysis of actual building use such as spot metering. Thanks Hannah

Hi Jeff For your first question, I've definitely seen this as an issue and we try to get the auditing agent to use the values listed in Energy Star when completing their study just to avoid this getting flagged by GBCI. But you should be able to clear up the issue with GBCI with a narrative explaining why there is a discrepancy. That said, I'm not sure if the Source/Site issue makes sense to me, because Energy Star lists both values on the Statement of Energy performance, and therefore the values should match. With regard to your second question, I think I get how your metering is set up, but I'm not quite sure I understand your question - are you trying to include in your energy end-use breakdown as well as in this credit both the chilled water line meter and all downstream components? The trick to this credit is that you have to use the energy end-use breakdown to document, so if you are including downstream equipment, then also including the upstream metering wouldn't fly. Let me know if I missed what you are asking, I'm happy to clarify more. Hannah
