LEEDuser’s viewpoint
Frank advice from LEED experts
LEED is changing all the time, and every project is unique. Even seasoned professionals can miss a critical detail and lose a credit or even a prerequisite at the last minute. Our expert advice guides our LEEDuser Premium members and saves you valuable time.
Credit language
Requirements
Establishment
Install advanced energy metering for the following:
- all whole-building energy sources used by the building; and
- major end uses that represent 20% or more of the total annual consumption of the building minus plug load use.
The advanced energy metering must have the following characteristics.
- Meters must be permanently installed, record at intervals of one hour or less, and transmit data to a remote location.
- Electricity meters must record both consumption and demand. Whole-building electricity meters should record the power factor, if appropriate.
- The data collection system must use a local area network, building automation system, wireless network, or comparable communication infrastructure.
- The system must be capable of storing all meter data for at least 36 months.
- The data must be remotely accessible.
- All meters in the system must be capable of reporting hourly, daily, monthly, and annual energy use.
Performance
Program the facility’s energy management system to set an alarm whenever the energy consumption and
peak demand rise above the anticipated amount by more than 5%. The anticipated consumption and peak should be determined by analyzing historical facility performance and weather and operating conditions and should be set on at least monthly, preferably daily.
Demand measurements must be taken in time increments no longer than the increments used for utility billing or in one-hour increments, whichever is less time.
On at least a monthly basis, report the facility’s utility
peak demand and total consumption and compare it with the data for the previous month and the same month from the previous year.

What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.

Frequently asked questions
Are tenant spaces considered to be an “energy end use”? In other words, can we achieve this credit by metering tenant energy consumption?

Reference Guide Correction
Description of change: In Further Explanation, Determining Major Energy End Uses, before the paragraph starting with “Choosing what equipment and components to group”, add the following paragraph:
It is acceptable to exclude a small portion of the total loads from each end-use category. Not more than 10% of the total connected load of any of the required end-uses is permitted to be excluded from that end-use advanced metering data collection. Not more than 10% of the total connected load of any of the end-uses where metering is required is permitted to consist of loads not part of that end-use.
Internationally Applicable: No
