Poor air quality has an impact on our bodies. These consequences can be more or less serious, depending on the case: headaches, asthma, chronic illnesses, cardiovascular diseases, etc.
For health, environmental or regulatory reasons, it may be necessary to measure and analyze Outdoor Air Quality.
NEXELEC sensors are capable of measuring different pollutants, depending on the model. Depending on the country and the environment, thresholds may vary.
Depending on WHO and ANSES regulations, thresholds may differ from one country to another.
The values set out below are valid for ERP (Etablissements Recevant du Public) in France.
Carbon Dioxide (CO2)
CO2 is a good indicator of Indoor Air Quality. If ppm levels are too high, ventilate as soon as possible.
Volatile organic compounds (VOCs)
These compounds are emitted by paints, glues and other solvents. If the concentration is too high, ventilate as soon as possible.
Fine Particles (PM)
PM are grouped into 3 categories: PM1, PM2.5 and PM10
Fine particles are often found in dust and smoke. Prolonged exposure presents a health risk. When the threshold is too high, open the windows to renew the indoor air.
Formaldehyde (HCHO)
Formaldehyde can be found in new furniture, cleaning products and so on. If your detector emits a Red LED, take action as soon as possible.
Carbon monoxide (CO)
If carbon monoxide levels reach excessive levels in a room, it presents a potentially fatal hazard. It’s crucial to detect the origins of CO in the environment, and to have all combustion appliances inspected, such as stoves, boilers, stoves and so on. If the threshold is too high, ventilate the room as much as possible.
Depending on the model, products offer lighting and energy optimization, acoustic monitoring, space and safety management, and automation scenario options.
For RISE, SIGN
The calibration process is performed automatically by the device every 8 days. No maintenance required. The reliability of CO2 measurements is guaranteed throughout the product’s lifetime.
You can also calibrate the CO2 sensor manually:
The LED changes to Green, indicating that manual calibration of the product has been successfully completed. If a Red LED lights up, repeat the operation.
NFC (Near Field Communication) is a magnetic field technology used to exchange data between a product and a smartphone.
To configure the product, simply :
For AERO, AERO Lite, AERO CO2, CARBON, SENSE, ATMO models.
The calibration process is performed automatically by the device every 8 days. No maintenance required. The reliability of CO2 measurements is guaranteed throughout the product’s lifetime.
You can also calibrate the CO2 sensor manually:
1. Place your product near an open window for at least 2 minutes.
2. Quickly press the product’s central button 6 times
The green LED lights up throughout the calibration process (for approx. 10 seconds).
Once the LED has gone out, manual calibration is complete.
NDIR (Non-Dispersive Infrared) sensors offer highly accurate measurement of CO2 levels. They use infrared spectroscopy to specifically detect CO2 molecules, enabling reliable and consistent measurements.
NDIR sensors are designed to maintain their calibration and accuracy over long periods, making them a durable choice for continuous monitoring of CO2 levels.
NDIR sensors are effective and reliable in an environment where CO2 levels reach at least a minimum of 400 ppm for several consecutive hours: at night and at weekends in communal areas, during the day in a bedroom.
Correct ventilation of communal areas helps reduce the risk of viruses spreading through the air.
Measuring CO2 levels enables you to quickly check the quality of air renewal, and encourages occupants to air the room if necessary.
CO2 can cause headaches, drowsiness, difficulty concentrating, mild nausea and rapid heart rate.
NEXELEC’s CO2 sensors provide reliable and accurate measurement of CO2 concentration.
NEXELEC sensors can measure various environmental parameters such as noise or ambient brightness. Depending on country and environment, and according to WHO recommendations, thresholds may vary.
Noise level
Exposure to excessive noise can lead to hearing fatigue and long-term deafness. If the measured noise level is too high, identify the source and move away from it, or use hearing protection.
Brightness
Ambient lighting has a significant impact on our ability to work and maintain your productivity. If insufficient, it can lead to ophthalmic fatigue.
In any indoor environment, lighting plays a crucial role in the productivity, concentration and well-being of occupants. Good lighting can boost energy, improve mood and reduce eyestrain.
Measuring brightness is therefore essential to guarantee the visual comfort, safety, energy efficiency and functionality of interior spaces.
To reduce noise pollution, it is useful to implement corrective measures:
NEXELEC noise and sound level sensors help reduce noise pollution in indoor spaces.
Generally speaking, at 80 dB and above, the danger threshold is considered to have been reached after 8 hours of noise exposure. Above 130 dB, any exposure to noise, even short-term, is considered highly harmful.
NEXELEC noise sensors measure the sound environment in interior spaces, helping to ensure the well-being of occupants.
Poor noise management will also have an impact on occupants’ concentration levels, influencing their alertness too. The impact is not only physical, but can also be psychological. Studies show that exposure to noise increases levels of the stress hormone cortisol. This can lead to increased anxiety, fatigue, depression and even sleep disturbance.
NEXELEC noise sensors enable you to effectively monitor the sound environment in indoor spaces.
Noise is a constant feature of everyday life. But unfortunately, it can be harmful to humans. In France, 3 million employees are exposed to excessive noise levels in the workplace. Without realizing it, hearing loss can set in very quickly and lead to deafness.
To anticipate these risks, NEXELEC noise sensors help you keep an eye on the noise level around you on a daily basis, in a preventive manner.
Measuring occupancy rates is essential for the smooth running of interior spaces. Measurements can be analyzed to make informed decisions: optimize space layout, identify under-used or overcrowded areas, and adjust resources according to actual needs.
With NEXELEC presence sensors, you can maximize space efficiency, reduce costs and enhance the occupant experience.
There are several ways to improve light levels:
Maximize natural light: make the most of natural light by positioning desks close to windows and using skylights where possible. Natural light helps regulate our circadian rhythm and raises our alertness level.
Choose the right artificial lighting: if you need artificial lighting, opt for energy-efficient LED bulbs, which provide white, natural light. Make sure, too, that light intensity is adjustable to suit different tasks and individual preferences.
Avoid glare and reflections: computer screens can generate annoying glare and reflections. Use blinds, anti-glare filters or adjust screen orientation to minimize these distractions and reduce eyestrain
Provide well-lit break areas: pay particular attention to the brightness of break and relaxation areas. Well-lit areas promote relaxation and help reduce occupant stress. Consider using soft, warm lighting to create a soothing atmosphere.
Ensure even lighting throughout the space: make sure lighting is evenly distributed throughout the interior space to avoid dark or overexposed areas. Uniform lighting helps maintain a pleasant, balanced atmosphere
NEXELEC brightness sensors help to achieve comfort objectives in interior spaces.
Presence sensors contribute to energy savings by detecting the presence or absence of people in a space. This means that lighting, heating, ventilation and other systems can be automatically adjusted according to this detection.
By reducing unnecessary energy consumption, NEXELEC presence sensors contribute to significant energy savings and lower energy costs.
A presence detector is a device that detects the presence of people in a given area for a defined period of time. NEXELEC presence sensors are designed to react quickly to movements and provide precise data on the actual occupancy level of spaces.
In an enclosed space, heat rises and stagnates at the ceiling, where the temperature is de facto a little higher than in the rest of the room. To ensure correct measurement of ambient temperature, we recommend mounting the detector on a wall 50 cm below the ceiling.
Building Management System (BMS) is a system designed to centralize, monitor, and control all technical equipment within a building: HVAC, lighting, energy metering, blinds, alarms, etc.
A BMS collects real-time data to optimize energy performance, improve occupant comfort, and reduce operating costs. As a true cornerstone of Smart Buildings, a BMS enables intelligent and automated management of technical installations while facilitating maintenance and regulatory compliance, particularly within the framework of the BACS regulation.
A Building Management System (BMS) is used to monitor, control, and optimize the operation of a building’s technical equipment. Through real-time data collection, it automatically adjusts heating, ventilation, air conditioning (HVAC), and lighting settings.
Its dual objective is to improve energy performance while ensuring occupant comfort. A BMS also facilitates anomaly detection, preventive maintenance, and multi-site management. It is a strategic tool for building managers aiming to reduce energy consumption and comply with regulatory requirements such as the BACS regulation.
Building Management Systems (BMS) are becoming progressively mandatory in certain commercial buildings under the BACS regulation (Building Automation & Control Systems).
This regulation requires the installation of an automation and control system for buildings equipped with HVAC systems exceeding specific power thresholds. The objective is to improve energy performance and reduce CO₂ emissions.
Implementing a compliant BMS therefore helps anticipate legal requirements while optimizing the technical operation of the building.
Nexelec solutions integrate seamlessly into a Building Management System (BMS) architecture by ensuring the collection, transmission, and operational use of field data. Nexelec sensors (CO₂, temperature, humidity, occupancy, light, etc.) continuously monitor key building parameters to support supervision and energy management.
Data is transmitted via LoRaWAN to gateways such as MASTER or LINK, and can then be converted into BACnet/IP for smooth integration into an existing BMS. This architecture efficiently bridges IoT technologies with traditional BMS platforms, without heavy construction work, while enhancing energy performance, regulatory compliance, and usage optimization.
The BACS regulation requires the installation of automation and control systems to optimize the energy performance of commercial buildings.
Nexelec sensors contribute to compliance by providing reliable data on occupancy, indoor air quality (CO₂), temperature, and humidity. When combined with NAVIXIS supervision and integrated into a BMS via MASTER, they enable performance analysis, HVAC setpoint adjustments, and improved overall energy management of the building.
Yes. Thanks to the NAVIXIS platform, multiple buildings can be monitored from a single interface.
Facility managers can compare energy performance, track indoor air quality, and monitor equipment connectivity across their entire property portfolio. This centralized approach is particularly well suited for public authorities, branch networks, and multi-site commercial organizations.
Data collected by our sensors and consolidated within our supervision platform enables precise, centralized, and continuous energy monitoring.
Dashboards and automated reports simplify energy management, support compliance with regulatory requirements (BACS, Tertiary Decree), and provide clear visibility on the actions implemented to improve energy performance.
