Commercial HVAC Heat-Load Calculations: VRF vs Chilled Water Systems
Selecting the optimal air conditioning architecture for commercial buildings: heat load dynamics, fresh air CFM, and operational energy efficiency.
Heat Load Factors in Dense Workspaces
Calculating HVAC capacity requires accounting for human occupancy heat gain (approx 450 BTU/hr per person), computing equipment, server heat output, solar radiation through glazed curtain walls, and lighting loads.
Quick Answers
What is the standard rule of thumb for office air conditioning tonnage?
A standard rule of thumb is 1 Ton of refrigeration per 120–150 sq ft of office space, adjusted for glass orientation and occupant density.
