Front 24

Enhanced commissioning

Back 24

a set of best practices that go beyond fundamental commissioning to ensure that building systems perform as intended by the owner. These practices include designating a commissioning authority prior to the construction documents phase, conducting commissioning design reviews, reviewing contractor submittals, developing a systems manual, verifying operator training, and performing a post-occupancy operation review

Front 25

Fundamental commissioning

Back 25

a set of essential best practices used to ensure that building performance requirements have been identified early in the project's development and to verify that the designated systems have been installed in compliance with those requirements. These practices include designating a commissioning authority, documenting the owner's project requirements and basis of design, incorporating commissioning requirements and basis of design, incorporating commissioning requirements into the CDs establishing a commissioning plan, verifying the installation and performance of specified building systems and completing a summary commissioning report
