Temperature

Temperature is the parameter people feel most directly — and the baseline every other reading is interpreted against. Too cold and occupants are distracted and uncomfortable; too warm and alertness drops and humidity problems follow. A stable, well-chosen range keeps people comfortable and productive.

Why measure it

Comfort you can feel — and prove.

Temperature drives perceived comfort more than any other parameter, and it interacts with humidity, energy use and even infection control.

Comfort & focus

A few degrees off the comfort band is enough to distract people, trigger complaints and reduce concentration and productivity.

Health & recovery

In clinical and care settings, a stable temperature supports patient comfort, sleep and recovery — and keeps staff effective through long shifts.

Drives humidity

Temperature and humidity move together. Control temperature and you keep relative humidity in its healthy band, avoiding condensation and mould.

Energy & compliance

Overheating and overcooling waste energy. Continuous data lets you tune setpoints to comfort standards like EN 16798 and ASHRAE 55.

How to read it

Comfortable in the middle, costly at the edges.

Unlike pollutants, temperature has a sweet spot rather than a ceiling — both too cold and too warm carry a cost. Aim for the centre band and watch the drift toward either edge.

Too cold
Uncomfortably cold for occupied rooms. Expect complaints and lost focus.
18–20
Cool
Slightly below comfort for most. Fine for corridors and storage.
20–24
Comfortable
The comfort band for offices, classrooms and clinical spaces.

Warm
Slightly above comfort. Alertness starts to dip; consider cooling.

Too warm
Uncomfortably warm. Productivity drops and humidity issues follow.
Where it comes from

What moves the temperature.

Indoor temperature is the balance of heat coming in and heat leaving — driven as much by occupancy and equipment as by the weather outside.

01

HVAC & setpoints

Heating and cooling systems are the primary lever. Schedules that ignore real occupancy leave rooms too hot or too cold.

02

Occupancy & equipment

People, computers and lighting all add heat. A full room warms up quickly, especially with poor ventilation.

03

Solar gain & envelope

Sun through glazing and a poorly insulated envelope swing temperatures through the day and across seasons.

04

Outdoor weather

Cold snaps and heatwaves push the system harder; continuous data shows where comfort and energy trade off.

What good looks like
20–24 °C

Keep occupied spaces in the 20–24 °C comfort band; the exact target shifts slightly with season, clothing and activity level.
