pmv: Predicted Mean Vote

Description

Computes Fanger's predicted mean vote

Usage

pmv(clo, met, air.temp, saturation)

Arguments

clo

Thermal insulation of clothing in [clo] (underwear, blouse/shirt, slacks/trousers, jacket, socks and shoes are approximately 1 clo)

met

Physical activity in [met] (one person seated at rest is approximately 1 met)

air.temp

Indoor air temperature (assumed equal to mean radiant temperature) in [C]

saturation

Ratio of moisture content to moisture content of saturated air at the same temperature, in [%] (approximately the same thing as relative humidity)

Value

The predicted mean vote, a value between -3 (cold) to +3 (hot)

Details

Compute the predicted mean vote for one or more combinations of clo, met, air temperature and moisture saturation. The inputs arguments can be scalars or vectors.

Examples

# With scalars
pmv(clo=1.0,
    met=1.2,
    air.temp=19,
    saturation=40)
# With vectors
pmv(clo=c(1.0, 1.5),
    met=c(1.2, 0.6),
    air.temp=c(19, 30),
    sat=c(35, 40))
