When can municipalities use codes to make their own rules?

Figure 1: An energy recovery ventilator (ERV) unit installed at an administration building in Massachusetts. The ERV exchanges heat between the outdoor air and the ventilation from the occupied spaces. It operates in air-side economizer mode when the outdoor air temperature is below 60°F and modulates the outside air damper and return air damper to maintain the mixed air temperature setpoint.

Figure 4: In addition to changing the compliance process in ASHRAE 90.4 from 2016 to 2022, the mechanical load component (MLC) values are more stringent across all climate zones. ASHRAE acknowledged that the MLC values in the 2016 edition needed to be lowered to ensure reasonable energy efficiency. Courtesy: Bill Kosik, WSP
