This article investigated the feasibility a new load-based method of test for assessing the comprehensive performance figure of merit of roof top units. The measurements, according to the new load-based approach, characterize the relative changes in the unit performance when it operates in the field as if the unit was installed in an actual building. Depending on the mode of operation and on the outdoor air dry-bulb temperature, the roof top unit efficiency was about 41% to 9% lower than the steady state efficiencies determined by using the ASHRAE 116 Standard if the operation mode of the roof top unit was with economizer closed to the fixed minimum outside air position and without any speed control. When both the economizer and speed control technologies were activated, the measured efficiency increased to 205% with respect to the steady state efficiency. The focus of the load-based test was to provide data that could be used to project energy use and change point linear inverse modeling following ASHRAE Guideline (2014) could be applied to the data to compare expected annual energy use for the baseline (i.e., roof top unit with minimum outside air) to the improved modes of operation with fan speed control and outside air economizer control.
