Description
Proper design of space heating, cooling, and air-conditioning systems requires detailed knowledge of the building envelope's overall heat, air, and moisture performance. This chapter discusses the fundamentals of combined heat, air, and moisture movement as it relates to the analysis and design of envelope assemblies. Guidance for designing mechanical systems is found in other chapters of the ASHRAE Handbook.
