Information Captured and Monitored for Utility Submeters Installed in New Buildings

E-Mon D-Mon submeters for electricity, gas, and water are now routinely installed in many APS new building projects, especially those vying for the LEED Measurement and Verification (M&V) credit. These meters measure energy and gas use at 15 minute intervals throughout the day, as well as during peak energy demand hours. Such information helps generate accurate statements of utility use at specific locations, allowing performance comparisons and trouble shooting.

A guideline for M&V and submetering has been created by FD+C as well as steps to capture this important data in the District Database (along with standard utility bill data) for ease of analysis by M&O. The data and Database is continually monitored and analyzed by M&O staff and reported to the Executive Director.

In addition, M&O is able to isolate and identify specific circuits or appliances within a facility that are zapping energy and make adjustments in correcting the problem. While the sophisticated technology was initially costly, it will more than pay for itself in electric savings. EnTouch Controls portable measuring devices remove the laborious deduction process out of pinpointing energy hogs.
