Extra Point = Building Performance Partnership

Great question! I think this is pretty cool initiative. Unfortunately USGBC doesn't have any more info on it right now. LEEDuser is watching it closely and we'll post info on it when we can.

Any update on the Extra Point for signing the USGBC data release form? Getting ready to submit plans for 5.1 and 5.2. Thanks!

Jennifer, I'm glad you mentioned this.USGBC has just recently been building out its Building Performance Partnership, which includes this. You can learn more about on this page.I haven't yet talked to anyone who has tried to earn this point, so please post back here with what you learn in the process.

Dear all,

I am developing an M&V plan for a large commercial mall (1 for EAc5.1 and 1 for EAc5.2).

The initial electrical/power design groups the hot water primary pumps and the boilers together under one MCC (Motor Control Center).

Since the IPMVP standard is flexible in terms of the number of meters/submeters and the entities being measured, do you think that I have to meter the boilers and the hot water pumps separately, or I can meter the "total heating" consumption by installing a meter on the MCC level (measuring boiler consumption + hot water pumps)? Or do I have the choice between both options?

Similarly for other MCCs which group "Cooling Tower Condenser pumps" with the "Chiller water primary pumps".. Can these be measured together under "Total Cooling"?

Thanks!

I would like to take this opportunity to point out a common mistake in the LEED submissions for this credit. The M&V Plan for 5.1 is not the same as 5.2, they are very different so don't submit the same plan for both.

Regarding your metering issue - you can meter these items together. When calibrating the model does it breakout these pumps or lump them together under and overall energy end use "pumps"? If lumped together calibrate to the total. If separate end uses in the model you could try and separate the two types of pumps using perhaps some spot measurements or run time information from the BMS to derive the energy use of the different pumps. The whole question is what information do you need to calibrate your model and what is the cheapest way to get that information?

The modeling program lumps all pumps together.

However, for the first scenario (Boilers + Hot water pumps), I think these should be separated, because the modeling program separates boilers (reported under "Heating") from Hot water pumps (reported under "Pumps").

Thanks Marcus!

But if the pumps are lumped together then you could calibrate the electric use of the pumps to the combined pump sub-meter.

The boiler heating energy use should be a gas sub-meter (assuming that is the fuel source). I am also assuming that there is more than one gas end use (hot water, cooking, etc.). If the boiler is the only gas use then the utility meter would work.
