ASHRAE Guideline 36 aims to standardize a set of best practices for HVAC control. This paper compares a homegrown, single-duct VAV terminal reheat strategy developed and implemented at Appalachian State University with the Dual Maximum strategy included in Guideline 36. The two strategies have similar goals relating to reduced minimum airflows, but they differ in the details of implementation. The Homegrown strategy controls the reheat valve with the zone temperature. Discharge air temperatures are monitored and when that temperature reaches a threshold temperature, the VAV damper modulates to cap the discharge air temperature at a threshold setpoint. The implications of this variation are discussed and compared to operational outcomes established for the dual maximum strategy outlined in Guideline 36P.
