CBE Thermal Comfort Tool

CBE's thermal-comfort tool separates air and mean radiant temperature, air speed, humidity, metabolic rate in met and clothing in clo, with SI/IP controls and PMV/adaptive methods. Charts show comfort relationships; a two-axis view still uses the other model inputs. Above 1 met it can add activity-generated air speed, which should be disabled for activity that does not create that air movement. The stated applicability excludes unhealthy individuals, clothing above 1.5 clo, highly impermeable clothing and sleeping/bedding conditions. The adaptive method further requires an occupant-controlled naturally conditioned space with no installed mechanical cooling, no operating heating, activity 1–1.3 met and clothing adaptability. Save/Reload/Share controls are offered; the official help calls the tool free.
