Intelligent Weatherization

Whole House Heat Load Calculations

This one day course covers the methods, skills and inspection techniques Building Analysts need to calculate whole house heat load. This course will follow the ACCA Manual J heat loss procedure, utilize Blower Door air leakage information to determine heat loss associated with infiltration, and account for heat loss associated with air-sealed duct systems. Detailed building information of post-weatherization conditions are input into an Excel spreadsheet to determine a realistic post-weatherization heating load on the building. This heating load is then used to help select the most appropriate size of replacement furnace. Building Analyst & Heating Technicians Modules
