The ASHRAE Handbook is published in a series of four volumes, one of which is revised each year, ensuring that no volume is older than four years. The Handbook can be purchased at the ASHRAE Bookstore by clicking on this link.
TC 4.1 is responsible for writing and maintaining the following two chapters in the ASHRAE Handbook - Fundamentals Volume
This heat and cooling load calculation, developed by Air Conditioning Contractors of America (ACCA), can be manually or computer calculated. Most computerized versions provide input values for an easier and faster calculation. Most software versions offer instructions on inputting data. Jun 01, 2010 ASHRAE Fundamentals presents a RTS method in detail for cooling load calculations. The RTS approach may be further developed by combining relevant equations, and sorting and rearranging equations in a close-form. The close-form of the RTS approach can reduce the amount of calculations, and is useful for developing a new procedure to.
Chapter 17 - Residential Cooling and Heating Load Calculations
This chapter covers cooling and heating load calculation procedures for residential buildings. It covers detailed heat balance methods that serve as the basis for the cooling load calculation, and simplified cooling load procedures suitable for hand calculations. Discussion of straightforward heating load calculations are also included.
Chapter 18 - Nonresidential Cooling and Heating Load Calculations
This chapter covers cooling and heating load calculation procedures for non-residential buildings. The chapter starts by explaining fundamental load calculation principles. Next the common elements of cooling load calculation are described (e.g., internal heat gain, ventilation, infiltration, moisture migration, fenestration heat gain). Finally, two methods of heating and cooling load calculation are discussed: the heat balance (HB) method and the radiant time series (RTS) method. Extensive examples using the ASHRAE HQ buiiilding in Atlanta are used to illustrate application of the principles described in this chapter.
TC 4.1 is working on the revision of these chapters for the 2025 edition of the ASHRAE Handbook - Fundamentals.
