Using Bulls-Eye Commissioning to Save Energy in Commercial Buildings
Abstract
Building system commissioning comes highly
recommended by energy efficiency experts; however,
it is rarely undertaken due to the cost and care needed
to do a comprehensive job. Many existing utility
meters provide whole-building 15-minute interval
data that can be used to pinpoint fan control and
HVAC schedule problems. Bulls-eye commissioning
uses interval metering to focus detailed
commissioning efforts.
This paper concentrates on a single customer and
how bulls-eye commissioning can be applied to focus
the commissioning process. Significant energy
savings were found by using interval data in
conjunction with outside air temperature to isolate
problems with schedules and in the economizer
controls. Evaluation of main meter profiles allows
detailed commissioning work to be better focused
and more effective without the wait and expense of
full commissioning services. Bulls-eye
commissioning can be applied on its own or can be
coordinated with traditional commissioning. In either
case, the main meter profile shows what will directly
impact total energy use and the customer's bill.
