Developing the Business Case for Submetering: Leveraging GSA’s Portfolio to Demonstrate Submeter Functionalities, Range of Benefits and Cost Savings

Recent industry trends show that installation of metering devices after the primary utility meter that measure actual resource consumption are bringing multiple benefits to commercial building owners. These submetering systems could allow GSA to monitor energy usage for individual tenants, departments, whole floors, pieces of equipment or other loads individually to account for their actual energy usage.The GSA developed a Submeter Framework that provides a standardized means to map submeter functionalities to a range of benefits. The framework also assists stakeholders with identifying data needed to determine the associated costs and monetary savings resulting from submetering projects.
