Automated Performance Testing System

The Automated Performance Testing (APT) System defines the state-of-the-art in building diagnostics by combining computerized control of the Minneapolis Blower Door system with multi-channel pressure measurement and data logging capabilities.

The APT system is operated from a user supplied laptop computer using custom software developed by The Energy Conservatory. During an automated airtightness test, the APT system adjusts the speed of the Blower Door fan while simultaneously monitoring and recording the building pressures and fan flow rates. The APT can be configured to record pressures from attached building zones (attics, garages etc.) during the Blower Door test to help diagnose complex air leakage paths. Blower Door test results are recorded, displayed on the screen and can be saved to a file.

When used with our TECLOG data logging software, the APT system becomes a powerful data logging system with up to 8 high resolution pressure channels and 8 analog voltage input channels (which can be connected to optional temperature, relative humidity and carbon monoxide sensors). The APT system allows you to simultaneously monitor and record the interaction of building pressures along with other performance variables (e.g. temperature, relative humidity) over time.
