Building Commissioning

Peace of Mind & Total Assurance

Building commissioning involves the systematic verification that your building’s systems have been designed, installed, thoroughly tested, and will perform as intended. A commissioned building offers optimal energy efficiency, indoor air quality and occupant comfort, while assuring that ongoing operating and maintenance costs are minimal.

Too often, systems that were designed and built to high standards fall into a state of neglect. System setpoints drift due to human error or faulty sensor calibration; pump pressures and flow rates change; air volumes drift out of spec and/or fail to align with changes in facility requirements. These all equate to poor performance that impacts indoor comfort, equipment performance, energy cost and equipment life.

Building commissioning for new projects is a process often written to project specifications. This process provides written documentation that building systems are installed and perform in accordance with project design specification. Commissioning for existing systems is a bit more complicated, but often even more critical.

Commissioning for existing buildings (sometimes referred to as retro-commissioning) is a systematic process for investigating, analyzing, and optimizing the performance of building systems by improving their operation and maintenance to ensure their continued performance over time. This process helps make the building systems perform interactively to meet the owner’s current facility requirements. Retro-commissioning also can identify adjustments to systems that may be required due to changes in facility operations and/or other energy-related improvements. One common example is re-evaluating the system after a lighting upgrade. Lighting upgrades can significantly reduce cooling loads. System control setpoints and control strategies, therefore, need to be revisited.
