TECLOG4

TECLOG4 by The Energy Conservatory is professional data acquisition and test-control software for building performance work. It connects to TEC instruments—such as the DG-1000 gauge and Minneapolis Blower Door fans—to capture, display, and manage multi-channel measurements in real time. Designed for energy auditors, commissioning providers, weatherization teams, and building scientists, TECLOG4 streamlines blower door, duct leakage, and zonal pressure diagnostics while improving accuracy and documentation.

Key capabilities:

• Real-time logging and graphing of pressures, flows, and related channels across multiple devices
• Automated test control with stable setpoint (cruise) and step-based sequences for blower door and duct tests
• Synchronized multi-gauge, multi-fan operation for single-family, multifamily, and large-building projects
• On-screen dashboards with live calculations and user-defined annotations for clear test documentation
• Built-in calculations for common leakage and pressure metrics, with trend visualization
• Data export to common formats (e.g., CSV) and quick sharing of test files for review and reporting
• Windows-based application with USB/Ethernet connectivity and offline playback for post-processing

TECLOG4 helps you run tests consistently, see issues as they happen, and leave each job with reliable, well-organized data.
