ANSI/ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers)

ANSI/ASHRAE are standards developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers to ensure the safety, comfort, and efficiency of building systems like heating, cooling, and ventilation. These guidelines specify best practices for designing, installing, and maintaining HVAC systems. They help engineers and builders create indoor environments that are healthy, energy-efficient, and cost-effective. While not mandatory, many codes and regulations reference these standards, making them essential for quality and compliance in building design and operation.
