Our project building has central air-handlers, which provide heating and cooling for the tenant spaces i.e. heating and cooling by air only.

Greetings, We have a doubt about the credit EA C3.2 from LEED EB O&M. What is the minimum time to measure performance of the major’s building systems by the breakdown of energy?

The LEED Online form requests that “monthly and annual summaries of the metered energy usage for each of the subsystems”.

For natural gas metering applications, is continuous logging of instantaneous flows a requirement? Most meters just put out totalized pulses, so I'm assuming that's fine... Any thoughts?

I am wondering if a commercial building, where over 90% of the building is submetered tenant space would qualify for this credit.

On page 200 of the LEED-EB reference guide, Table 1- Sample Summary of Energy and Metering Capacity lists major energy-consumption subsystems and end-uses.

In our office building, the annual Gas Consumption accounts for more than 40% of the total annual energy consumption. The gas is used for Heating and for Cooking (for a Restaurant).

We have a meter that measures: chiller + pump + lighting system. Since we are not discriminating by "end use": would this meter qualify towards this credit? Thanks GH

Hi all, I'm confused about when OR over what period of time does the breakdown need to capture. I understand that it needs to roll up to the EAc1 declared annual energy use (mbtu).

If we had to meter things like hot water usage and chillers on a building level to comply with EAp2/c1 to do building-level metering of all incoming energy inputs, would we automatically be able to
