This TC is responsible for the following chapters in the Fundamentals Volume:
Heat, Air, and Moisture Control in Building Assemblies - Fundamentals
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.
Heat, Air, and Moisture Control in Building Assemblies - Material Properties
This chapter contains material property data related to the thermal, air, and moisture performance of building assemblies. The information can be used in simplified calculation methods as applied in Chapter 27, or in software-based methods for transient solutions. Heat transfer under steady-state and transient conditions is covered in Chapter 4, and Chapter 25 discusses combined heat/air/moisture transport in building assemblies. For information on thermal insulation for mechanical systems, see Chapter 23. For information on insulation materials used in cryogenic or low-temperature applications, see Chapter 47 of the 2010 ASHRAE Handbook—Refrigeration. For properties of materials not typically used in building construction, see Chapter 33 of this volume.
Heat, Air, and Moisture Control - Examples
This chapter draws on Chapter 25’s fundamental information on heat, air and moisture transport in building assemblies, as well as Chapter 26’s material property data. Examples here demonstrate calculation of heat, moisture, and air transport in typical assemblies. For design guidance for common building envelope assemblies and conditions, see Chapter 44 of the 2011 ASHRAE Handbook—HVAC Applications.

Building Envelopes
Proper building envelope design requires knowledge of the physics governing building performance as well as of building materials and how they are assembled. This chapter provides practical information for designing new building envelopes and retrofits to existing envelopes, always with the notion that the envelope must work well in concert with the building’s surroundings and the HVAC system. The information can also be useful for those involved with building envelope investigation and analysis. This chapter was developed with the integrated design approach in mind and assumes that the architect, HVAC designer, building envelope designer, and others involved in envelope design and construction communicate and understand the interrelationships between the building enclosure and mechanical systems. Integrated design requires a clear statement of the owner’s project requirements (OPR) and design intent, and is described in greater detail in Chapter 58. That chapter may be used as a basis for finding common agreement among designers and engineers using the integrated design approach. The growing use of integrated design in project delivery highlights the building envelope as the principal site where architectural design and mechanical engineering meet.
