ASHRAE Guidelines

Definition

ASHRAE Guidelines are a set of recommended practices and standards developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to ensure effective design, installation, and operation of heating, ventilation, and air conditioning (HVAC) systems. These guidelines help in optimizing energy efficiency, indoor air quality, and overall system performance, making them essential for space heating and cooling applications.
