ASHRAE

Key ASHRAE standards referenced in building due diligence and operations: Standard 55 (Thermal Environmental Conditions for Human Occupancy — defines comfort zones using PMV/PPD model), Standard 62.1 (Ventilation for Acceptable Indoor Air Quality — minimum outdoor air rates, e.g., 8.5 L/s/person for offices), Standard 90.1 (Energy Standard for Buildings — baseline for LEED energy credits and many building codes), Standard 189.1 (Design of High-Performance Green Buildings), Guideline 0 (Commissioning Process), Standard 180 (Inspection and Maintenance of Commercial HVAC Systems). ASHRAE Fundamentals Handbook provides design data including climatic data for worldwide locations. ASHRAE standards are referenced by LEED, WELL, and many national building codes including BNBC.

ASHRAE standards are the global benchmark for HVAC design and indoor environment quality. Understanding which ASHRAE standards apply helps facility managers evaluate whether building systems are designed and operating to professional standards, and provides the basis for improvement programmes.
