When designing the overall HVAC system, there are several important factors to consider: • Load Calculation: Determining the heating and cooling load requirements of the building based on factors such as size, orientation, insulation, and occupancy. • Energy Efficiency: Selecting equipment and components with high energy efficiency ratings to minimize energy consumption and operating costs. • Air Distribution: Designing an effective system for distributing conditioned air throughout the building, considering factors such as airflow, duct design, and zoning. • Indoor Air Quality: Incorporating measures to ensure adequate ventilation, filtration, and humidity control to maintain a healthy and comfortable indoor environment.
