Demand Control Ventilation

Demand Control Ventilation System

A demand control ventilation (DCV) system with a CO2 sensor allows you to maximize energy savings while maintaining optimal building ventilation.


for Commercial/Industrial new construction and existing buildings

Customer Incentive

  • $500 per DCV with CO2 sensor

Service Provider Incentive

  • $50 per DCV with CO2 sensor

Distributor Incentive

  • $50 per DCV with CO2 sensor

Equipment Eligibility

  • This offer is intended for DCV equipped with self-calibrating sensors or other types of sensors whose calibration warranty period by the manufacturer is 15 years or more.
  • Incentive applies to the installation of DCV with CO2 sensors to single-zone constant volume ventilations system. Qualifying spaces include retail, office, primary/secondary school gymnasiums, post-secondary school classrooms, community center meeting spaces, exercise centers/sports arenas, senior/nursing/long-term care facility’s common areas, cinemas and performing arts, hotel conference rooms. Other spaces may qualify, please contact an Enbridge Gas Energy Solutions Advisor.
  • Mall common areas, office break rooms and telephone/data entry facilities with zones larger than 500 sq. ft. are not eligible. Spaces with energy recovery ventilator (ERV) or heat recovery ventilator (HRV), multi-zone systems or variable air volume (VAV) are not eligible.
  • Qualifying spaces most be heated during heating season by natural gas fueled equipment. For new construction applications, this equipment is not eligible to buildings/spaces where demand control ventilation is required by current building code.
  • Applications with free cooling economizers are eligible for this prescriptive equipment.

More Information About DCV With a CO2 Sensor

DCV is an automatic reduction of outside air intake to meet the actual occupancy requirements of a space.

Demand Control Ventilation System

How DCV With a CO2 Sensor Works

Conventional ventilation systems operate at pre-determined ventilation rates, generally based on the maximum occupancy level of the building. Because the level of occupancy changes continuously throughout the day, energy is wasted when occupancy drops below these pre-set rates.

The process of DCV is used to ventilate as well as condition the air during heating or cooling periods, based on the level of occupancy at any given time. Sensors are used to monitor conditions in the occupied space and provide real-time feedback to the controls. The controls then determine the fan speed, which modifies the ventilation rates to match the number of occupants in the building.


  • Increased energy savings
  • Reduced operating costs
  • Improved thermal comfort
  • Less environmental impact


Like all components of an HVAC system, routine maintenance is required. In specific circumstances, there may be a specific maintenance plan in place. The maintenance plan provides for inspection and calibration of control system components, including sensors, actuators and transducers.

Building Applications

DCV with sensors is ideal for buildings with varying occupancy levels, such as office buildings and retail stores.
