It’s standard practice for most new buildings to install whole-building energy metering, which satisfies this prerequisite. In addition, those projects simply need to commit to sharing energy use data and electrical demand data (if metered) with USGBC for five years.
If your project design doesn’t currently include compliant energy metering, you’ll need to ensure that metering is installed that measures energy use for the LEED project building. All energy supplied by a utility company or campus central plant must be metered. Teams are not required to meter locally generated sources of energy that are dedicated to the project building, such as photovoltaic systems. However, teams may want to consider installing additional metering when doing so will support the project’s ability to meet energy performance goals during operations.
Remember that energy meters cannot be shared with another building. There are no special requirements for the meter type except that it must be permanent. Meters must track energy use at one-month intervals, at minimum.
USGBC has not provided a commitment letter template. However, Minimum Program Requirement 6 from the LEED 2009 rating system included a requirement for sharing water use data, which is outlined on Project Information Form 1. The language on the PIf1 form can provide teams with a good starting point for developing their own commitment letter.
To support energy management and identify opportunities for additional energy savings by tracking building-level energy use.
Install new or use existing base buildingThe base building includes elements such as the structure, envelope, and building-level mechanical systems, such as central HVAC, and materials and products installed in the project (e.g., flooring, casework, wall coverings).-level energy meters, or submeters that can be aggregated to provide base building-level data representing total building energy consumption (electricity, natural gas, chilled water, steam, fuel oil, propane, etc.). Utility-owned meters capable of aggregating base building-level resource use are acceptable.
Commit to sharing with USGBC the resulting energy consumption data and electrical demand data (if metered) for a five-year period beginning on the date the project accepts LEED certification or typical occupancy, whichever comes first. At a minimum, energy consumption must be tracked at one-month intervals.
This commitment must carry forward for five years or until the building changes ownership or lessee.
We have commenced a project seeking LEED V4 certification and wish to know more sharing metered information through third party sources. We are a non US project and not overly familiar with Energy Star.
Can anybody explain what third party sources are available?
Can you point me to where the concept of third party sources is referenced? If so I will attempt to answer the question.
I have a similar question - I am curious about what types of building level energy meter options are out there? I am also seeking LEE V4 certification for a Core and Shell project and our team is curious about other options besides a BAS system. Thank you.
At the whole building level the ones from the local utility are best and the easiest way to earn this prerequisite.
So you need a meter for each major fuel type and a means to record the data. The BAS systems typically just interface with the meters to make recording and reading easier. You can do that with datalogger equipment too. On the electrical side there are meters that can be built into electrical panel boxes.
These meters need to be permanently installed. So select the metering equipment that does the job at the lowest price.
Thank you. So then you just need meters on all building level energy consumption, but not ONE total aggregating meter that compiles all of these meters into one place? There are existing utility meters, we were just curious if we needed to buy an additional meter that aggregated all meters to one.
No aggregation needed. You just need a building level meter for each fuel used.
