The mission of the Utility Metering and Controls Knowledge Resource is to create and disseminate knowledge in metering throughout USACE. Congress mandated the installation of advanced meters via the Energy Policy Act of 2005 (EP Act 2005) and the Energy Independence and Security Act of 2007 (EISA 2007). This Act requires the metering of all federal buildings for electricity where practicable. The EISA of 2007 requires metering for natural gas and steam by Oct. 1, 2016. The Department of Defense guidance requires the installation of electric, gas, steam, and water meters. The building selection criteria for metering applies to buildings with an estimated annual utility costs of $35,000 or greater. This typically equates to buildings 29,000 square feet or larger, but can include smaller facilities depending upon function and use and all reimbursable tenants regardless of size.
