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 It Matters
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.
