F25 — Heat, Air, and Moisture Control in Building Assemblies–Fundamentals (I-P)
Click here to purchase
Proper design of space heating, cooling, and air-conditioningsystems requires detailed knowledge of the building envelope’s overall heat,air, and moisture performance. This chapter discusses the fundamentals ofcombined heat, air, and moisture movement as it relates to the analysis anddesign of envelope assemblies. Guidance for designing mechanical systems isfound in other chapters of the ASHRAE Handbook.
