More specifically, HVAC will be disabled when windows are open, and HVAC will be available when windows are closed. This measures adds ZoneVentilation:WindandStackOpenArea objects to zones with operable windwos to model natural ventilation, then adds AvailabilityManager:HybridVentilation to each zone with natural ventilation and control HVAC and natural ventilation in a hybrid manner. When windows are open, HVAC will be disabled; when windows are closed, HVAC will be available. HVAC can be an airloop system or a zonal system. open_area_fraction Window Open Area Fraction (0-1) A typical operable window does not open fully. The actual opening area in a zone is the product of the area of operable windows and the open area fraction schedule. Default 50% open. Double true false 0.5 min_indoor_temp Minimum Indoor Temperature (degC) The indoor temperature below which ventilation is shutoff. Double false false 20 max_indoor_temp Maximum Indoor Temperature (degC) The indoor temperature above which ventilation is shutoff. Double false false 24 delta_temp Minimum Indoor-Outdoor Temperature Difference (degC) This is the temperature difference between the indoor and outdoor air dry-bulb temperatures below which ventilation is shutoff. For example, a delta temperature of 2 degC means ventilation is available if the outside air temperature is at least 2 degC cooler than the zone air temperature. Values can be negative. Double false false 2 min_outdoor_temp Minimum Outdoor Temperature (degC) The outdoor temperature below which ventilation is shut off. Double true false 20 max_outdoor_temp Maximum Outdoor Temperature (degC) The outdoor temperature above which ventilation is shut off. Double true false 24 max_wind_speed Maximum Wind Speed (m/s) This is the wind speed above which ventilation is shut off. The default values assume windows are closed when wind is above a gentle breeze to avoid blowing around papers in the space.
