Thermal Comfort Principles and Practical Applications for Residential Buildings
by Robert Bean, Fellow ASHRAE, Distinguished Lecturer, Retired Engineering Technology Practitioner

Three Key Principles:

Heat loss and gain calculations are not thermal comfort calculations.

HVAC design in of itself is not thermal comfort design.

HVAC contracting in of itself is not thermal comfort contracting.

Download the book for the details of what thermal comfort design is all about.
