Commercial HVAC Load Calculation – Sizing

Accurate HVAC System Design for Energy-Efficient Commercial Buildings – EnerSolution Inc.

Proper HVAC system sizing is critical for achieving energy efficiency, occupant comfort, and operational cost savings in commercial buildings. EnerSolution Inc. provides professional commercial HVAC load calculation services to ensure heating, ventilation, and air conditioning systems are accurately designed for offices, high-rises, retail spaces, and industrial facilities.

Our process follows industry-recognized standards and involves a comprehensive assessment of building geometry, occupancy, insulation, lighting, and equipment loads. By calculating heat loss and heat gain for each space, we ensure HVAC systems are neither undersized—which can lead to discomfort and inefficiency—nor oversized, which increases costs and reduces performance.

With our commercial HVAC load calculations, property managers and building owners can make informed decisions on equipment selection, energy optimization, and system upgrades. Accurate sizing also supports long-term reliability, reduced energy consumption, and improved indoor air quality.
