Manual N Overview
Manual N is the ACCA standard for commercial heating and cooling load calculations. We handle light commercial, mixed-use, and small commercial buildings—calculating loads zone by zone with proper consideration for ventilation requirements, occupancy schedules, lighting loads, and equipment heat gains that residential calculations don't address.
Why Manual N Calculations Matter
Commercial buildings have fundamentally different load profiles than homes. Internal heat gains from lighting, equipment, and occupancy often dominate the cooling load. Manual N properly accounts for these factors to ensure accurate system sizing.
