This meeting included the First Green Commissioning Authority, the general contractor, mechanical, electrical and control contractors and owner representatives. The commissioning plan and process were reviewed, and contractor roles and responsibilities were detailed. Several other on-site meetings were conducted as construction progressed to address the commissioning process and other related topics. Functional tests are typically a step-by-step procedure of manipulating the systems and controls in order to test the operation of the equipment through each mode and how they respond to different variables within each mode. Tests were designed to prove correct equipment operation using system changes and overrides that will most closely mimic changes that an end user would do while operating the building.
