For questions about this report,contact WSEC Commercial Technical Support at 360-539-5300 or via email at com.techsupport@waenergycodes.com C403.6.1 Air systems serving Identify supply air systems serving multiple multiple zones zones and the zones they serve on plans; indicate whether system is VAV and method of primary air control;or provide supporting documentation for applied exception to VAV C403.6.1 VAV air terminal Provide equipment schedules on plans that list primary supply all VAV air terminals and types(fan-powered airflow series and parallel air terminals,single duct and dual duct air terminals,etc) For each air terminal include:maximum primary supply airflow rates during zone peak heating and zone peak cooling;maximum terminal airflow during reheating,recooling or mixing;minimum ventilation airflow rate,and the basis for these values;if IMC or ASHRAE 62.1 multiple zone equation is the basis for minimum flow rates,provide this calculation on plans C403.6.2 Single duct VAV Indicate single duct terminal units are terminal units configured to reduce primary supply air before reheating or recooling C403.6.3 Dual duct systems- For systems with separate warm air and cool terminal units air ducts,indicate terminal units are configured to reduce the flow from one duct to minimum before mixing with air from the other duct C403.6.8C40 VAV system static- Indicate locations of duct static pressure 3.6.9 pressure sensors and sensors on plans;include at least one sensor DDC set points per major duct branch;verify controller setpoint pressure at each sensor is<_ 1.2 inch w.g. For systems with zone level DDC,indicate controls are configured to monitor zone damper positions and reset static pressure setpoint based on the zone requiring most pressure;include control logic that automatically detects and generates an alarm if any zone excessively drives reset logic,and allows building operators to exclude zones from reset logic C403.6.4 VAV system supply Indicate controls automatically reset supply air reset air temperature in response to building loads or outdoor air temperature;or exception applied C403.6.5 Multiple-zone VAV For systems with zone level DDC controls, system ventilation indicate controls are configured to optimization controls automatically reduce outdoor airflow in response to changes in system ventilation efficiency;or exception applied Page 19125
