The room isn't hot. It's stale. Your members can't tell the difference.
Co-working sells sharp afternoons. A closed meeting room with eight people in it crosses 1,000 ppm CO₂ in under an hour, and the people inside only know they're tired. A logger shows exactly where and when the air goes stale.

Smart Logger in a Gurugram co-working space: CO₂, temperature and humidity per room, so fresh-air schedules are set from the real curve.
Why stuffy air is a product problem before it is a comfort one
Published studies measure slower decision-making and more errors as CO₂ climbs past roughly 1,000 ppm, well below the level anyone notices as discomfort. A meeting room designed for six, booked for ten, with the door shut and the fresh-air damper on its default schedule, gets there before the first coffee break.
Operators manage temperature because members complain about it. Nobody complains about CO₂ — they just book somewhere else next month. The fresh-air schedule was set by the fit-out contractor for an average day and has never been checked against how the rooms are actually used.
The fix starts with knowing. A CO₂ logger in the busiest rooms and open desks shows the daily curve: which rooms go stale, at what hour, and how long it takes to recover. Fresh-air dampers and AHU schedules can then be set against what the rooms actually experience instead of a guess.
From a logger to rooms that stay sharp
Log the busiest rooms
Wireless CO₂-temperature-humidity loggers in meeting rooms and dense desk zones. Battery-powered, live the day they go in.
Find the stale hours
The daily curve shows which rooms cross 1,000 ppm, when, and how long they take to recover. Usually it is two or three rooms, every afternoon.
Then let the floor run itself
SKW EnergyOS brings in more fresh air only when rooms get stuffy — not the same fresh air all day — and runs the AHUs to occupancy, inside bounds your team sets.

Questions we get asked
Is this monitoring our members?
No. The loggers measure the air in the room — CO₂, temperature and humidity. They record nothing about who is in it.
Can we show the readings to members?
Yes. The status board is built to be left on a wall screen, and operators use live air-quality as a selling point for the space.
Do we need the landlord's BMS?
Not to start. The loggers are standalone. Adjusting fresh-air schedules is usually a conversation with the AHU operator; closing the loop autonomously comes later, on the building's BMS.
How many loggers do we need?
Start with the meeting rooms that get booked most and one per dense open zone. Most floors need five to ten to see the pattern.
