Update of clothing database for existing and new Western clothing ensembles, including effects of posture, body and air movement : Report on manikin measurements for ASHRAE 1760-TRP.

• ASHRAE Research Project RP-1760 aimed to update thedatabase of western clothing as used in ANSI/ASHRAE Stan-dard 55-2013, Thermal Environmental Conditions for HumanOccupancy (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 ThermalComfort Criteria (ISO 2005), and ISO Standard 9920-2009,Ergonomics of the Thermal Environment—Estimation ofThermal Insulation and Water Vapor Resistance of a ClothingEnsemble (ISO 2009). The previous database, established inthe 1970s and 1980s, relied mostly on single-zone manikinsand did not provide detail on air and body movement effects oninsulation. Insulation values of up to 70 clothing ensembles(31 male, 39 female) were measured in a static standingposture at 0.2, 0.4, and 1 m/s–1 (0.66, 1.31, and 3.28 ft/s–1) airspeed, walking in 0.2 and 1.0 m.s–1 air speed, and in a sittingposture in 0.2 m.s–1 air speed. Measurements were conductedin 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 thewind 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 changesin commonly worn clothing styles.
