 Section 2. METERING CRITERIA
1. METER INSTALLATION CRITERIA. Meters and ancillary equipment should be
installed in new or retrofit construction to facilitate management of
utilities. Meters shall be installed when the following criteria are met:
(a) New construction--New facilities should be provided with electric,
water, and natural gas meters, as appropriate. Steam meters should be
provided for new facilities where the annual energy cost component of steam
will exceed $50,000.
(b) Energy retrofit programs --Meters shall be installed on Energy
Conservation Investment Program (ECIP) projects if the total project SIR is at
least 2.5, including the cost of the meters, and if the cost of the meters
does not exceed 10 percent of the total cost of the project. Meter costs
shall include both hardware and installation. If meter installation cannot be
cost-justified for one facility, combining a number of facilities in the
analysis may warrant meter use. For Energy Technology Applications (ETAP)
projects, meters should be included if desired by the activity and Claimant.
Figure 2-4 is an example of how to evaluate a meter installation using these
criteria.
(c) Energy-Converting Devices: All energy-converting devices with
outputs greater than 20 MBTU/hr or 1,000 kW, such as boilers, turbines, and
generators, shall be metered. Metering both input and output is desired, but
where cost considerations limit metering to input or output only, select the
most useful and cost effective.
(d) Customer Requirements: Meters may be installed at the customer's
request for energy accountability or for project validation.
(e) Public Works Center (PWC)/Public Works Department (PWD)
Requirements: Meters shall be installed by the PWC/PWD for billing and energy
management.
(f) Preinstalling Meters: Hardware and plumbing may be installed so that
portable meters can be used later. If criteria to install permanent meters
are not met, the criteria shall be reapplied for portable meter
preinstallation. Portable meters can then be installed for spot checking and
profiling. Portable meters can also be used to determine whether proposed
meter sites meet criteria.
2. METER LOCATION CRITERIA. Meters must be in strategic locations that will
provide energy managers with adequate information to control their utility
systems. They shall provide information to determine when load shedding is
required, identify situations where energy losses can be avoided, verify that
procedural changes will result in decreased utility costs, and allow metering
of tenants. In selecting locations, preference shall be given to locations
that are clean, well-lighted> and minimize damage possibilities. It is also
important to select sites where excess heat or other potential causes of
