Retrocommissioning
Building ReCx
Finding and correcting building systems deficiencies can be like searching for needles in a haystack. That’s where retrocommissioning (ReCx) comes to the rescue. ReCx is a systematic evaluation that unearths MEP systems issues that, remaining undetected, would result in higher operation and maintenance costs and increased comfort issues. (ReCx can also be included as part of an ASHRAE Level I, II, or III Energy Audit.)
During retrocommissioning, our project performance team conducts a detailed site assessment. We then perform operational testing, sensor calibration, and short-term diagnostic monitoring to uncover opportunities to correct and enhance equipment functionality, indoor air quality, and system longevity.
ReCx diagnostics may include:
HVAC System performance testing, including control sequences
Lighting level assessment (foot candles and lighting power density)
Duct leakage testing
Airflow (TAB) and temperature measurements
Water flow (TAB) and temperature measurements
Infrared thermography
Solar shading analysis
Relative humidity and indoor air quality testing
