Optimize ventilation with air quality sensors

Written by Louise | Nov 20, 2025 10:38:47 AM

Why measure air quality (IAQ) to optimize ventilation?

Ventilation evacuates pollutants, limits excessive humidity and ensures healthy air for occupants.

Yet most systems operate on fixed cycles, independent of actual building variations and precise indoor air control, which limits the effectiveness of the overall ventilation system.

By measuring key indicators, such as CO₂, fine particles, volatile organic compounds (VOCs) or even temperature and humidity, an IAQ sensor provides a precise, instantaneous view of the indoor environment and enables the system to be supervised. This approach makes it possible to identify areas and times when reinforced ventilation is required, offering effective control to maintain optimum IAQ and improve the air management system.

 

 

Dynamic control thanks to real-time data

Nexelec sensors provide continuous, real-time data on IAQ, enabling us to propose solutions adapted to each situation, and to improve the efficiency of ventilation systems through precise monitoring of environmental parameters.

  • Automatic adaptation to actual needs: ventilation can be modulated according to measured thresholds and detected parameters.

  • Reduction of over-ventilation periods: a frequent problem in poorly regulated buildings, impacting IAQ, which these sensors help to solve, taking into account all relevant parameters and increasing the overall efficiency of building control.

  • Better anticipation: a gradual rise in CO₂ can signal an imminent increase in occupant numbers and influence IAQ, paving the way for air management solutions and guaranteeing optimum efficiency through analysis of key parameters.

 

 

Indoor comfort and energy performance: a new balance

Using data from IAQ sensors helps to achieve a dual objective: guaranteeing optimum air quality while controlling energy costs, thanks to tailor-made solutions and monitoring of pollutants present.

  • Improved comfort: adjusted ventilation maintains acceptable levels of CO₂, humidity and pollutants, reducing drowsiness, headaches or sensations of stale air, while optimizing IAQ thanks to tailored solutions.

  • Lower energy consumption: limiting excess ventilation reduces heat loss and cuts heating and cooling requirements, without compromising IAQ, and offers energy-saving solutions while controlling pollutants.

  • Better-informed decisions: continuous analysis brings to light trends that do not appear with one-off measurements, contributing to better IAQ and enabling the definition of relevant solutions for pollutant management.

All in all, the combination of sensors and control enables significant savings to be made without compromising occupant health or IAQ, while offering concrete, effective solutions for reducing pollutants in all buildings.

 

 

 

An indispensable approach for modern buildings

Faced with growing energy performance obligations and the need to guarantee a healthy indoor environment, the integration of an Indoor Air Quality (IAQ) sensor has become essential. This innovation enables managers to benefit from precise monitoring and optimize ventilation, while protecting the health of occupants.

Relying on reliable, instantaneous data, this innovation offers the possibility of adjusting ventilation systems, improving comfort and reducing operating costs, while ensuring optimum IAQ and contributing to the overall health of users, thanks to solutions tailored to each building.

The adoption of this innovation represents a real lever for modernizing buildings, guaranteeing a healthy, high-performance indoor environment, and protecting the health of occupants over the long term.
