Precision HVAC Sizing: The Consultant's Guide to Load Calculation and System Selection

In my more than three decades as a global HVAC and MEP consultant, I have witnessed firsthand the substantial economic and environmental penalties incurred when the art and science of sizing are neglected. Oversized systems short-cycle, failing to dehumidify effectively and wasting energy, while undersized systems run perpetually, struggling to meet demand and burning out components long before their time.

This book is dedicated to demystifying the complex interplay of thermodynamics, building science, and climate data that governs the sizing process. It is a practical guide that bridges the gap between theoretical load calculations and real-world system selection, drawing on international standards and practical field experience. My goal is to equip designers, engineers, and students with the methodologies, tools, and critical thinking required to ensure every HVAC system they touch is perfectly matched to its application, delivering the trifecta of comfort, energy efficiency, and reliable longevity.

Precision is not a luxury in HVAC design; it is a necessity. Let this guide be your essential companion on the path to mastering it.
