Last month, we tested readers on commissioning three of the many automatic temperature control (ATC) sequences of operation associated with the secondary hot water process heating system for an industrial building application. This month’s Back2Basics is to water balance this existing system and to test readers on water balancing the primary — secondary water system at maximum design water flow during the heating season. Not included in this test are the following TAB requirements:
The energy retrocommissioning team continues to include the facility manager, process engineering manager, ATC operator, commissioning engineer, TAB engineer, and if possible, a LEED Accredited Professional. Going forward, the team, and more specifically the facility manager, will continue to be responsible for collecting the incoming utility bills and measure them to the past utility bills to compare the difference in energy usage, as well as to maintain good boiler log operating data.
