The Bonneville Power Administration (BPA), a non-profit federal agency under the U.S. Department of Energy serving the Northwest, has purchased 14 web-based energy monitoring systems for measuring the energy performance of packaged rooftop HVAC units on commercial buildings.
BPA has installed the 14 HOBO U30 Remote Monitoring Systems in various service territories throughout the Pacific Northwest to collect data on HVAC unit energy consumption and building thermostat call settings. Each 15-channel monitoring system enables multiple HVAC units to be monitored at once, and the data is made available on the web via Onset’s HOBOlink™ website.
“The data is being analyzed and will assist in determining the energy savings associated with performing advanced maintenance services to packaged rooftop HVAC units,” said Erik Boyer, an engineer with BPA.
“Ultimately, this information will help us determine the amount of money BPA will offer businesses to perform these services in the Northwest.”

According to Boyer, the monitoring equipment also helps ensure that the HVAC systems were connected properly and has enabled BPA to investigate system performance.
BPA will be funding another project this summer aimed at measuring the energy performance of packaged rooftop HVAC units and is planning to utilize the Onset monitoring systems to collect the energy performance data.
