How a structured RCx process uncovers hidden issues, improves comfort, and delivers measurable energy savings.
What Is Retro-Commissioning (RCx)? Retro-commissioning (RCx) is the systematic process of evaluating and optimizing the performance of an existing building’s systems—HVAC, controls, air distribution, hydronic systems, and supporting equipment. Unlike major capital upgrades, RCx focuses on improving what you already have. Over years of operation, buildings drift: schedules change, sensors lose calibration, economizers get overridden, […]
7-Step New Construction Building Commissioning Process for High-Performance Buildings.
Commissioning is a structured, quality-focused process that verifies building systems are designed, installed, tested, and operating in accordance with the Owner’s Project Requirements (OPR). When delivered successfully, commissioning reduces operational risk, improves energy performance, enhances occupant comfort, and supports long-term asset value. For owners, developers, and construction teams, commissioning is not an end of the […]
Existing Building Commissioning (EBCx): Retro- and Re-Commissioning Explained
Commissioning is often associated with new construction, yet many of the greatest performance improvement opportunities exist in occupied, existing buildings. As facilities age, equipment performance degrades, control strategies are overridden, and system operation gradually drifts from original intent. Existing Building Commissioning (EBCx) provides a structured, engineering-led approach to understanding how building systems operate today, and […]
Why Building Commissioning Standards Matter for Facilities
Imagine a baseball game being played in which no one kept score. Not only would it be difficult to tell who won at the end of nine innings, but chances are each team would have a different assessment of what happened. Being able to measure your performance against a documented set of standards is essential […]
