separate air distribution systems from those serving zones requiring only comfort conditions;or shall include supplementary control
provisions so that the primary systems may be specifically controlled for comfort purposes only.
Plans reference page/section: NA
✓ 13.Humidity control.Where a humidity control device exists it is set to prevent the use of fossil fuel or electricity to produce relative
humidity in excess of 30 percent.Where a humidity control device is used for dehumidification,it is set to prevent the use of fossil fuel
or electricity to reduce relative humidity below 60 percent.
Plans reference page/section: NA
✓ 14.Humidity control.Where a humidity control device exists it is set to maintain a deadband of at least 10%relative humidity where no
active humidification or dehumidification takes place.
Plans reference page/section: NA
✓ 15.Ventilation.Ventilation,either natural or mechanical,is provided in accordance with Chapter 4 of the International Mechanical Code.
Where mechanical ventilation is provided,the system has the capability to reduce the outdoor air supply to the minimum required by
Chapter 4 of the International Mechanical Code.
Plans reference page/section: M003
✓ 16.Demand controlled ventilation(DCV).DCV is required for spaces larger than 500 ft2 for simple systems and spaces larger than 150 ft2
