About the Author
Unlike traditional books, the ASHRAE Handbook – Fundamentals is not written by a single author. It is developed collaboratively by ASHRAE technical committees, consisting of industry experts, researchers, professors, and practicing engineers from around the world.
ASHRAE is one of the most respected organizations in the built environment sector, also known for:
- ASHRAE Standards (90.1, 62.1, 55, etc.)
- Other handbook volumes: HVAC Applications, HVAC Systems and Equipment, and Refrigeration
This collective authorship ensures the content is peer-reviewed, technically accurate, and globally relevant.
Summary / Key Takeaways
Here are the core lessons and insights readers gain from the book:
- Clear explanation of fundamental HVAC engineering principles
- Accurate climate and weather data used worldwide for building design
- Detailed guidance on heating and cooling load calculations
- Scientific approach to thermal comfort and indoor air quality
- Practical formulas, charts, and tables for real-world engineering use
The book avoids guesswork and focuses on proven engineering science, making it a reliable reference for decades.
What Readers Liked
Professionals and students consistently praise this handbook for several reasons:
- Authoritative and globally accepted reference
- Extremely data-rich, with tables, charts, and equations
- Ideal balance between theory and application
- Frequently updated to reflect new technologies and climate data
- Essential for professional exams, design offices, and academic study
