Overture Indoor Air Quality Monitoring for Offices & Retail
In an office or a store, the air drives two things you can measure: how well people think, and how much you spend conditioning the space. As CO2 climbs through the day, cognition and decision-making decline. As ventilation runs flat-out on a fixed schedule, you pay for air changes you do not need. Overture® handles both. Our Room Sensors track the air in every space, and the system runs the equipment: it can push an ERV into boost mode, run demand-controlled ventilation, trip a make-up air fan, or run the air handler to circulate and filter the air. It does not just tell you the air is bad. It does something about it.
Why Offices and Retail Should Monitor and Control Their Air
The air in a commercial space affects your people and your operating cost at the same time:
- Lower CO2 keeps employees sharp. In a study of 302 office workers in six countries, each interquartile increase in CO2 of about 315 ppm slowed response times on the Stroop test by about 1.7% and reduced throughput (Cedeño-Laurent et al., 2021).
- Cleaner air at the point of use means a more comfortable space for staff and customers, fewer complaints, and lower absenteeism.
- In 2025 Overture supported a field study by TRC, paid for by California's CalNEXT program (report ET24SWE0015, final report December 19th, 2025). Its finding: “The results show that smart ventilation systems can maintain acceptable IAQ while reducing ventilation runtime compared to continuously operating systems provided the underlying ventilation infrastructure is properly designed and functioning.”
CO2 is one of the metrics every Overture Room Sensor tracks, alongside PM2.5, TVOC, relative humidity, and temperature. OSHA's 5,000 ppm limit is a worker-safety ceiling, not a comfort or performance target, and it tells you nothing about how people perform. The number that matters for an office is far lower. In the Harvard COGfx study, the best-scoring condition held carbon dioxide near 550 ppm with enhanced ventilation (Allen et al., 2016). Overture's carbon dioxide set point is adjustable from 600 to 2,000 ppm and ships at 1,000 ppm, so you can set it low and let the ventilation follow the room.
How Overture Monitors and Takes Control
An Overture system scales from a handful of rooms to hundreds of locations. Plug in the Room Sensors, open the web-based interface, and the system tracks the air and acts on it:
- Plug-in Room Sensors that run continuously, with no batteries to change
- Commercial-grade sensing of CO2, PM2.5, TVOC, relative humidity, and temperature
- Real-time data across every location in one web-based interface
- The system runs an ERV, a make-up air fan, a bath fan, a dehumidifier, or the furnace blower through a Smart Plug or Wall Control. A monitor shows you a number; Overture runs the equipment.
- Overture works for one building and is sized for 500 locations and up
