ASHRAE

American Society of Heating, Refrigerating and Air-Conditioning Engineers

ASHRAE is a global professional society advancing heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems. ASHRAE Standards establish minimum requirements for energy efficiency, indoor air quality, and building systems. Bare "ASHRAE [code]" partial references are accepted.

IndustrySyntax ASHRAE identifiers follow patterns like: ASHRAE Standard [Number]-[Year], ASHRAE Guideline [Number]-[Year], with addenda appended. Bare partial references (just "ASHRAE 90.1" with no "Standard" keyword or year) are accepted and normalised. Website →
