HVAC Design Standards

ASHRAE's HVAC Design Standards are a collection of key guidelines that define the planning, sizing, and performance criteria for heating, ventilation, air-conditioning, and refrigeration systems to achieve energy efficiency, indoor air quality, and occupant comfort. The hvac entry references core documents such as ASHRAE 90.1, 62.1, 55, and 15, providing technical direction for equipment selection, system design, and compliance verification.
