The rCloud app runs the equipment we manufacture, over a WiFi connection or iDevice hotspot. It is used to run industry specified tests, and then saves the results of the tests locally on the device and to a backend database in the cloud via Azure. The tests are not accessible for editing by the user once they are saved (local databases are encrypted). The completed tests can be viewed immediately on the App and also on the rCloud website once they are uploaded to the backend database.
IHWAP Diagnostics
This application assists with home weatherization by quantifying air leakage, calculating ventilation needs, and assessing duct system pressure against program standards. It helps prioritize air sealing and ensures compliance with energy efficiency guidelines.
- Zone Pressure Diagnostics (ZPD)
- Total External Static Pressure (TESP) calculation
- ASHRAE ventilation requirements
- Leakage reduction potential estimation
- ENERGY STAR compliance checks

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.
