Air Quality Monitoring in Coworking Spaces: Managing Changing Occupancy Throughout the Day
Coworking spaces are built around flexibility. A workspace may be almost empty early in the morning, busy by midday and quiet again in the evening. Meeting rooms can go from unoccupied to full within minutes, while event areas may suddenly host larger groups for workshops, presentations or networking sessions.
This constantly changing occupancy creates an important challenge for ventilation.
Traditional ventilation schedules are often based on fixed operating times rather than the actual number of people using a space. In a coworking environment, however, ventilation demand can change significantly throughout the day.
Indoor air quality monitoring with HibouAir can help building operators understand these changes in real time. When combined with HibouAir ControlHub, air quality data can also become part of a smarter ventilation strategy that responds to actual conditions inside the building.
Why occupancy changes air quality so quickly
When people enter an enclosed space, carbon dioxide levels naturally begin to increase. The more people occupying the room, the greater the ventilation demand.
In a large open coworking area, changes may happen gradually. A small meeting room is very different. Six or eight people entering a compact room and closing the door can cause CO2 levels to rise much faster.
This means that two rooms in the same building can have completely different indoor conditions at the same time.
One meeting room may remain comfortable because ventilation is sufficient, while another may experience increasing CO2 during longer meetings. An event area may perform well during normal working hours but require considerably more ventilation when thirty people gather there in the afternoon.
Continuous monitoring makes these differences visible.
A practical example: the busy meeting room
Consider a meeting room that is regularly used by project teams.
When the room is empty, CO2 levels are relatively low. At 10:00, eight people enter for a meeting. As the meeting continues, CO2 begins to increase.
If the ventilation system provides enough fresh air, the increase may remain controlled. If ventilation is insufficient for the number of occupants, CO2 can continue rising throughout the meeting.
At 11:00, everyone leaves. The room becomes empty and CO2 gradually falls again.
When this pattern is monitored over several days, the coworking operator may discover that the same room repeatedly experiences elevated CO2 whenever larger meetings take place. Instead of receiving a vague complaint that the room “feels stuffy,” the facility team now has measurable information showing when the problem occurs and how the room responds.
That information can be used to investigate ventilation performance and make better operational decisions.
From air quality monitoring to smart ventilation
Monitoring tells you what is happening. Smart control allows the building to respond. This is where HibouAir ControlHub becomes particularly useful.
HibouAir sensors can monitor changing indoor conditions, while ControlHub can use real-time air quality information as part of the ventilation control strategy.
In simple terms, the process becomes:
Occupancy increases → CO2 rises → HibouAir detects the change → ControlHub responds → ventilation increases
Later:
People leave → CO2 decreases → ventilation demand falls → airflow can be reduced
This creates a form of demand-based ventilation where the building responds to actual indoor conditions rather than relying only on a fixed schedule.
Why this approach fits coworking spaces particularly well
Demand-based ventilation can be valuable in many buildings, but coworking spaces are an especially good example because occupancy is so unpredictable.
A traditional office may have approximately the same employees arriving each morning. A coworking space can be very different from one day to the next.
Monday afternoon may be quiet. Tuesday could include several customer meetings. Wednesday might include an event with many visitors. One meeting room may be busy while the room beside it remains empty.
Running every ventilation zone at the same level regardless of occupancy may therefore be unnecessary. At the same time, reducing ventilation too much can create uncomfortable conditions when rooms suddenly become crowded.
Real-time air quality monitoring provides the feedback needed to understand this changing demand.
Creating a workspace that responds to how people actually use it
The main challenge in a coworking space is not simply that occupancy is high. It is that occupancy is constantly changing. Ventilation should ideally reflect those changes.
HibouAir provides visibility into indoor conditions by continuously monitoring air quality in different parts of the building. ControlHub can take the next step by using that real-time information to support smarter ventilation control.
Together, they create a practical approach to managing flexible workspaces:
HibouAir measures what is happening. ControlHub helps the ventilation system respond.
For coworking operators, this can mean better insight into how individual rooms perform, faster identification of ventilation problems and a building that responds more intelligently as people move throughout the space.
In an environment designed around flexibility, the ventilation strategy can become flexible too.
