Think sharper. Ship faster. Open a window.
CO₂ is the single strongest environmental lever on office productivity — and the cheapest to fix. Envora gives facilities teams and founders the number to argue with.
CO₂ is the cheapest productivity lever you can pull — and the only one with peer-reviewed numbers behind it.
Buildings argue with setpoints. People argue with stuffiness.
A modern office is the air version of a black box. People complain about stuffy rooms, about the afternoon slump, about "something being off" — but nobody has data. The building engineer knows the BMS setpoints; nobody knows what the actual air in the actual meeting room is doing right now.
The science is settled. Harvard's COGfx study put a 15% decision-making hit at 945 ppm and a 50% hit at 1,400 ppm — numbers reached in a full meeting room inside thirty minutes. The cost of that, across a knowledge-work team, dwarfs every facilities line except rent.
Envora puts a device in each meeting room, on each floor of open-plan, near the kitchenette and by the printer. Sub-second readings, a dashboard facilities and leadership share, alerts when a room hits its ceiling. The intervention is usually a window, a schedule change, or a BMS setpoint that was wrong all along.
Five workplace problems nobody is measuring.
The 3 PM meeting collapse
Conference rooms reliably cross 1,500 ppm within 30 minutes of a full agenda. Decisions suffer. Engineering tickets regress. Nobody names the cause.
The HVAC commissioned for 2019
Buildings are balanced for an occupancy that rarely matches reality — especially after hybrid changed how teams cluster. Envora shows where ventilation is paying off and where it is decoration.
The open-plan noise tax
Sustained 65 dBA in open-plan is worth 10% of short-term memory performance. That is a real number, and without a monitor in the room, you cannot argue for quieter policies or acoustic spend.
The printer / kitchenette PM
Toner, cooking aerosols and the slow laser-printer particulate halo sit under desks without any alarm. One device near the kit makes the unseen seen.
The winter dry complaint cycle
From November, humidity in heated offices drops under 25%. Sore throats, contact lens issues, dry coughs — all blamed on "going around". Envora shows it is the room.
CO₂, sound, light, IAQ — priced into every Wednesday afternoon.
Eight to six, in numbers.
-
08:45 First arrivals
Rooms still fresh. CO₂ baseline 450 ppm. Building just started pre-conditioning.
-
09:30 Stand-up rooms fill
Tight rooms already trending. Fifteen minutes to 900 ppm.
-
11:30 Pre-lunch peak
Longest meetings cross 1,200 ppm. Envora nudges facilities to pre-vent.
-
13:00 Lunch recovery
Open-plan back to baseline. Kitchen PM rises briefly.
-
15:30 The slump
Second CO₂ peak in the same rooms. This is where intervention earns its money.
-
18:00 End of day
Rooms clearing. BMS evening schedule begins.
Five routed alerts, before anyone complains.
- Meeting-room CO₂ approaches 1,200 ppm
- Open-plan dBA sustained above 65 for 30 minutes
- Desk light below 300 lx during working hours
- Printer-zone PM2.5 above 15 µg/m³
- Kitchenette VOC / IAQ degraded for more than 10 minutes
Numbers that pay facilities back in a quarter.
Four placements. In rough priority order.
-
Each meeting room× 1The highest-leverage placement — CO₂ spikes fastest and decisions matter most.
-
Open-plan clusters× 2One per 20–30 desks. Differentiate window side from core.
-
Kitchenette · printer× 1Catch the PM and VOC load that occupants walk through daily.
-
Phone booths · focus rooms× 1Small, sealed, heavy use. Worst CO₂ climbs in the building.
What office air quietly costs a knowledge team.
Long-term toxic gas exposure
A CO alarm chirps at 35 ppm. Your nervous system reacts at 1. Envora watches the band that does not set anything off — but accumulates anyway.

Winter heating in the UK regularly drops indoor humidity below 25%. Sore throats, cracked furniture, increased infection risk — all avoidable once you can see the number.

Wildfire smoke, urban traffic peaks, garden bonfires. The wrong ventilation strategy turns a bad outdoor hour into a bad indoor week.
