<html><head></head><body><h2>Air quality monitoring and people’s well-being</h2><p>Proper lighting and indoor air quality go hand in hand when it comes to productivity and people’s well-being. Indeed, both factors have a direct impact on the way we feel and interact at work or learn in the classroom. It is usually quite straightforward to identify situations where lighting needs improvement. However, it is much more difficult for people to assess the quality of the air inside a room. It is hence not uncommon to see meeting rooms and classrooms with poor ventilation, especially during the heating period.</p><p>According to <a href="https://eartharxiv.org/repository/view/527/" rel="noopener noreferrer" target="_blank">studies</a>, the level of carbon dioxide (CO2) in indoor spaces can directly affect people’s well-being. Poor air quality due to high levels of CO2 is linked to poor decision making, lack of focus, and drowsiness. Usually, people start experiencing some physical effects at 900 ppm but it is not rare to measure levels higher than 1000 ppm with peaks above 2000 ppm.</p><p>Good ventilation of schools and office spaces has also become a global concern with the recent COVID-19 outbreak. In this post-pandemic area, facility managers need to be able to measure the air quality on their premises and take appropriate measures in order to ensure a healthy environment for everyone.</p><h2>An innovative smart lighting solution</h2><p>To provide a viable solution to this situation, Astra LED and <a href="https://akenza.com/?utm_source=wevolver&amp;utm_medium=referral&amp;utm_campaign=airmonitoring" rel="noopener noreferrer" target="_blank">Akenza</a> have joined forces and developed an air monitoring smart lighting solution. The system can be split into two main building blocks: a lamp with an embedded sensor, and an Internet Of Things Connectivity Platform.</p><p>First, a sensor embedded in the lamp measures the air quality parameters of the room. These are typically the Carbon Dioxide (CO2) and Volatile Organic Compounds (VOC) levels, the temperature and the humidity. These parameters are then transmitted to the IoT platform via a low-power, long-range radio communication protocol (LoRaWAN connectivity). The IoT platform then monitors the air quality levels continuously and displays the data on a dedicated dashboard.</p><p>If the measured levels reach a predefined threshold, the
lamp changes color and intensity accordingly (green: acceptable, orange: high levels, red: critical levels). This visual
notification indicates that the room needs to be ventilated. In
the case of schools, this is used as a playful approach to raise
awareness about the topic and lead students to act.</p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 300px;"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjA3OTQ4NzQ3NTU0LXNtYXJ0bGlnaHRyZWQuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ=="><span class="fr-inner" spellcheck="false">The Smart Light changes to red in case of poor air quality</span></span></span></p><p>The smart lamp and sensors have been developed by Astra LED.

The platform makes it possible to connect to the cloud any
type of sensor via different connectivity technologies (e.g.
LoRaWAN, Sigfox, NB-IoT, LTE-M, 5G). The device can hence
be managed in one place, and the sensor’s data made available to the cloud in a dedicated application or ERP system.</p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 300px;"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjA3OTQ3MzYzNjU2LXNtYXJ0bGlnaHRyb29tLmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0="><span class="fr-inner" spellcheck="false">Smart Light in an office space</span></span></span></p><h2>The case of the city of Zug, Switzerland</h2><p>One of the first implementations of the system has been made

is a critical precondition to ensure the well-being of students
and the workforce as well as to ensure high productivity
