Illinois Home Weatherization Assistance Program (IHWAP) Diagnostics application for the University of Illinois. This app is the product of a collaboration between the Indoor Climate Research & Training Center’s Senior Weatherization Trainer, Nate Price, and me. The Zone Pressure Diagnostics (ZPD) function will quantify the connection between the house and a zone and between that zone and the outdoors. It will also estimate the total leakage reduction potential in the zone, which should assist with prioritizing air sealing measures. The Total External Static Pressure (TESP) function will calculate total pressure and the pressure caused by the various components of a duct system and compare them to Illinois Home Weatherization Assistance Program (IHWAP) standards for recommended replacement options. The American Society of Heating and Air-Conditioning Engineers (ASHRAE) function will calculate home ventilation requirements ensuring proper pollutant control and ENERGY STAR compliance.
