HVAC Energy & Load Calculations

Why Perform HVAC Energy and Load Calculations?

A well designed HVAC system ensures building comfort by adjusting internal temperatures, mixing air in rooms, maintaining humidity levels. When the system is properly sized for the building, it will operate unnoticed, and be energy efficient. Unfortunately, many HVAC systems fail to achieve these very basic objectives.
