This document discusses ways to achieve thermal comfort through building design, construction, and maintenance. It explains that thermal comfort is influenced by factors like air temperature, humidity, air speed, clothing, and activity level. Building codes aim to minimize discomfort rather than eliminate it, as different people experience comfort differently. Thermal comfort can be measured using the predicted mean vote (PMV) scale of -3 to +3. Guidelines recommend keeping the PMV between -0.5 and +0.5. The document then provides recommendations for achieving thermal comfort, including using HVAC to regulate mean radiant temperature, minimizing air leakage, allowing some occupant control, and maintaining and adjusting the thermal environment over time.
