Automated building and duct system airtightness testing app for mobile devices

TEC Auto Test is an automated building envelope and duct system airtightness testing app for mobile devices. The TEC Auto Test app allows the user to wirelessly connect with a DG-1000 or DG-700 pressure gauge to conduct an automated airtightness test of a building or duct system. The app will collect and store the required test data from the connected gauge (and flow device), and along with manually entered building and customer information, calculate and display test results in a PDF report. Project files can be geotagged using location services on your mobile device.

The app creates PDF test reports that can be viewed and exported using email or cloud sharing apps installed on your mobile device (e.g. Google Drive, Dropbox). Users can also export Project files that contain all test and building data within the Project. Exported Project files are in a XML file format. The app supports multiple airflow units including cfm, m3/h and l/s.

The new Wind Assistant feature can detect windy weather conditions and automatically make adjustments to the envelope test settings to improve test accuracy and repeatability. The Wind Assistant has multiple settings and is user configurable.

TEC Auto Test is designed to be used exclusively with testing equipment manufactured by The Energy Conservatory (TEC). The airtightness test standards supported by this version of the app includes seven building envelope standards: ASTM E779 Multi-Point standard, RESNET 380 Multi-Point standard, RESNET 380 One-Point standard, two variations of the ISO 9972 Multi-Point standard, and two variations of the CGSB 149.10 Multi-Point standard. In addition, the app includes one duct leakage test standard: RESNET 380 Total Duct Leakage standard.


• Wireless communication with a DG-1000 gauge using either Bluetooth or WiFi.
• Wireless WiFi communication with a DG-700 gauge along with a WiFi Link adapter.
• Automated fan control and data collection reduces operator error and ensures that tests are conducted the same way every time.
• Auto Test provides quality assurance by ensuring that tests are performed in accordance with test standards and that test data (i.e. pressure and flow readings) is collected directly from your TEC gauge and cannot be altered.
• The Wind Assistant™ feature can detect windy weather conditions and automatically make adjustments to the envelope test settings to improve test accuracy and repeatability.
• Project files can be geotagged and time stamped to verify when and where the test was conducted.
• Supports both building and duct system airtightness tests, and metric and non-metric units.
• Calculates and displays test results in a PDF report format that can be exported using cloud sharing apps on your mobile device.
• Complete Project files (containing all test and building data) can also be exported. Exported Project files are in an XML file format.
• Contains multiple default test protocols that define the type of tests and code compliance/test settings that the app uses when conducting a test. Protocols can be edited, deleted, and new protocols created.
• Project and test files can be easily copied to speed up data entry for large production applications.

What’s New

Version 1.9.0

Minor updates.

• Added dual test mode functionality for the ISO 9972 based test standards. ISO 9972 test files can now contain both depressurization and pressurization tests in the same file.
• Added the ability to choose the reporting pressure for the ISO 9972 based standards (50 Pa, 10 Pa or 4 Pa).
• Added alerts for fan pressure tubing connections when using Rings D, E and Ring 4.

Needs a few improvements

I am a RESNET HERS Rater who primarily specializes in multifamily housing. I use this for testing as many as 15 apartment units in a day (yes, with the help of an assistant).

Just my two cents worth on needed improvements as a HERS Rater:

1. For the iPad app, it needs to be able to work in landscape view for people who use keyboards with their iPad.

2. A duct leakage to outside test would be fantastic to have as an option.

3. On the iPhone/iPad, a way to deliver reports to iCloud would be nice.

4. This is probably a stretch, but to be able to share projects between an iPhone and iPad would be nice.

Now, my two cents worth on the good:

1. When RESNET implemented multi-point testing, I didn’t have this app or the means to connect my phone to my pressure gauges. When I was shown how to use this by my QAD provider, I ordered what I needed, downloaded this app and was off and running.

2. Love the geocoding. May not always get the address perfect, but darned close enough.

3. Report output is great. I have never had any problems.

4. The ability to create new test skeletons from existing tests.

Overall works well

Could be more interactive but gets the job done.
