HVAC Load Calculator
Calculate heating and cooling loads for your space to determine the right HVAC system size. Ensure optimal comfort, energy efficiency, and proper system sizing for your building.
Step 1: Building Specifications
Average
Insulation Impact
Good insulation can reduce heating/cooling loads by 20-30%. Consider upgrading insulation before oversizing HVAC systems for better energy efficiency.
Step 2: Climate & Requirements
21°C
Load Calculation Factors
HVAC load depends on building envelope, insulation, windows, occupancy, equipment, and climate. Proper sizing prevents energy waste and ensures comfort.
