Building  Commissioning is a systematic methodology that documents the entire  building process from the owner’s inception and design to construction  and occupancy. It is a quality-oriented process for achieving,  verifying, and documenting that the performance of facilities, systems,  and assemblies meets defined objectives and criteria. Tests are  performed on the mechanical systems to measure their energy output and  efficiency. HMC can perform these tests and verify that clients are in  compliance with required building system standards.
