Abstract

ASHRAE Research Project RP-1760 aimed to update the
database of western clothing as used in ANSI/ASHRAE Stan-
dard 55-2013, Thermal Environmental Conditions for Human
Occupancy (ASHRAE 2013a), ISO Standard 7730-2005,
Ergonomics of the Thermal Environment—Analytical Deter-
mination and Interpretation of Thermal Comfort Using Calcu-
lation of the PMV and PPD Indices and Local Thermal
Comfort Criteria (ISO 2005), and ISO Standard 9920-2009,
Ergonomics of the Thermal Environment—Estimation of
Thermal Insulation and Water Vapor Resistance of a Clothing
Ensemble (ISO 2009). The previous database, established in
the 1970s and 1980s, relied mostly on single-zone manikins
and did not provide detail on air and body movement effects on
insulation. Insulation values of up to 70 clothing ensembles
(31 male, 39 female) were measured in a static standing
posture at 0.2, 0.4, and 1 m/s–1 (0.66, 1.31, and 3.28 ft/s–1) air
speed, walking in 0.2 and 1.0 m.s–1 air speed, and in a sitting
posture in 0.2 m.s–1 air speed. Measurements were conducted
in three laboratories on three manikins with up to 34 individ-
ually controlled zones. In addition, vapor resistance was deter-
mined in 31 ensembles. This new database provides total,
intrinsic and air insulation values, vapor resistance, and cloth-
ing area factors as well as correction factors to estimate the
wind and movement effect on clothing insulation. Further-
more, the model to estimate the clothing area factor from insu-
lation values of the ensembles was updated reflecting changes
in commonly worn clothing styles.
