OP-T2-18: Energy Metering

As of July 2012, there are 10 University buildings which are fully metered. Metering at each building includes domestic water, chilled water, steam condensate and electricity. Natural gas for the University is purchased from the local utility company. The metering program has placed an emphasis on emulating utility-like function. Data acquisition is now done through a centralized panel in each building. Instep enterprise energy management software has been purchased and implemented to provide a centralized storage of data, historical analysis, financial billing, trending, and dashboard functions. These dashboard functions have the capability of providing information to a variety of end users (e.g. engineers, researchers, students). Instep is integrated with the panels in each building to obtain the meter data and dashboards. Development is under way to provide this data to the aforementioned variety of end users and to be made available publically on the University website. The University is currently engaged in a campus wide metering program to individually meter an additional 47 buildings. Commencement of this phase began in first quarter of 2011 with a completion expected in the first quarter of 2013. Beyond the 2013 phase, an additional 37 buildings have been identified for metering to be conducted through 2015. This would bring the total campus buildings with individual metering to 94 buildings by the end of 2015.
