Guidelines for energy efficiency and application of Green Technologies identify building system commissioning as a fundamental requirement.

Standard design services include occasional site review during construction. Near the end of construction this work includes spot checking of equipment and system start-up. Detailed system check out responsibility remains with the contractor and operator/owner which have proven to be unsatisfactory in the past. The commissioning service verifies and records operation of all critical systems. Each control device and interface is checked for proper operating sequence and conformance with design intent.

The results of providing a commissioning service should be:

  • Building operates as intended.
  • Less maintenance and operator time, to discover, and correct malfunctioning systems.
  • Better energy efficiency.
  • Improved system performance.
  • Improved training for operator personnel.

The commissioning process provides the owner with a building and systems operating as designed with documentation and training to maintain its performance.
