#thermal_zone_demand_control_ventilation_limits(thermal_zone) ⇒ Array<Double>

Determine the area and occupancy level limits for demand control ventilation.

and the minimum occupancy density in m^2/person. Returns nil if there is no requirement.

Parameters:

  • thermal_zone (OpenStudio::Model::ThermalZone) —

    the thermal zone

Returns:

  • (Array<Double>) —

    the minimum area, in m^2
