ASHRAE publishes Load Calculations Manual

ASHRAE published a guidance book designed to improve the performance and efficiency of design as it relates to load calculations. “Load Calculation Applications Manual” focuses on two methods of calculating cooling loads in non-residential buildings—the heat balance method and the radiant time series method. Author Jeffrey Spitler explained how understanding these methods is crucial when answering three primary design questions:

What is the required equipment size?How do the heating/cooling requirements vary spatially within the building?What are the relative sizes of the various contributors to the heating/cooling load?

The manual features in-depth examples, including the latest data for building materials, windows, weather, and internal heat gains. The CD that accompanies the book contains spreadsheets that compute the factors needed by the RSTM.
