Microclimate and the working environment.

We measure microclimate in offices, production halls, hospitals and schools and assess thermal comfort. Physical testing of the working environment is in our ATS 01-008 scope.

What we measure

Microclimate & working environment

01

Air temperature and humidity

Temperature −50 to 125 °C and relative humidity 0 to 100 %.

02

Air speed

0 to 5 m/s, relevant for draughts and ventilation.

03

Mean radiant temperature

The effect of warm and cold surfaces, measured with a globe thermometer.

04

PMV and PPD

Thermal comfort to EN ISO 7730:2008 and DIN EN 13779:2007.

FAQ

Frequently asked questions

What is workplace microclimate?

Air conditions at the workstation: temperature, humidity, air speed and radiant heat from surfaces.

What are PMV and PPD?

PMV is the predicted mean thermal sensation from −3 (cold) to +3 (hot); PPD is the predicted percentage of dissatisfied people. Both follow EN ISO 7730.

Is it accredited?

Yes. Temperature, humidity, air speed, mean radiant temperature and PMV/PPD are in our scope.
