This chapter draws on Chapter 25’s fundamental information onheat, air and moisture transport in building assemblies, as well as Chapter26’s material property data. Examples here demonstrate calculation of heat,moisture, and air transport in typical assemblies. For design guidance forcommon building envelope assemblies and conditions, see Chapter 44 of the 2019 ASHRAE Handbook—HVAC Applications.
