Which standard method is used to calculate HVAC loads for a base facility?

• A. ASHRAE Handbook calculations
• B. NFPA 70
• C. NEC
• D. ASHRAE 62.1

Answer: (A)

Calculating HVAC loads uses a standardized approach defined by the ASHRAE Handbook calculations. This method provides a systematic way to determine the heating and cooling loads for a base facility by incorporating climate data, building envelope characteristics (insulation, windows, envelopes), occupancy, lighting and equipment gains, ventilation, and infiltration. The result is the total sensible and latent load the system must handle, which guides equipment sizing and design conditions. NFPA 70 (the electrical code) and NEC govern electrical wiring and safety, not load calculation for HVAC sizing. ASHRAE 62.1 sets ventilation and indoor air quality requirements, which influence loads but is not the method used to calculate the loads themselves.
