Jeffrey Spitler, Ph.D., P.E., Oklahoma State University |
The ASHRAE Load Calculations Application Manual has been updated to include results from more than
four years of ASHRAE research. This presentation will give an overview of the state-of-the-art with an
emphasis on the new methods and data in the 2nd Edition of the Load Calculations Application Manual.

2 Application: Zoning and Load Calculation Basics: What Do You Do Early in Design When You Don't Have All the Answers

Air conditioning system sizing is an important aspect of the early building design process. Calculating cooling and heating loads can be challenging when all of the details regarding building construction and function are not well-defined. Making reasonable decisions and assumptions in the schematic design phase of a project is critical to selecting and applying proper HVAC solutions. This presentation will provide some guidance on these decisions and how they impact the building design process.

Load calculations require application of engineering judgment gained by experience, hard knocks and bullets dodged. Understanding the impact of each assumption is key to reaching a reasonable result within time constraints of modern fast-track design processes. Young engineers need to be able to recognize results that look unusual - and be able to backtrack and find their mistakes, not blindly use results because the computer says so.
