Ventilation

Install CO₂ sensors and we'll give you $200 per sensor.

Improved indoor air quality creates a healthier, more comfortable and productive workplace. Ventilation systems improve air quality by exhausting stale or polluted indoor air from a building and replacing it with "fresh" outdoor air. Proper ventilation reduces CO₂ levels along with other airborne contaminants (dust, odors, moulds, moisture, etc.).

The most basic ventilation system consists of an air-handling unit with a supply air fan and control dampers. The system mixes outside air with recirculated building air and redistributes the mixed air supply within the building (see Figure 1).

What type of ventilation system is best for my building?

• Fixed ventilation system – adequate for buildings with no significant changes in occupancy.
• Demand-controlled ventilation (DCV) system – optimal for buildings with variable occupancy. Power Smart incentive available for CO₂ sensors.

Talk to your local ventilation contractor to find out which system is right for you.
