ABSTRACT
Commissioning is a ‘support process’ to assist design, installation, start-up and maintenance processes to arrive, from the owner’s project requirements, to the desired results i.e. a well-performing, sustainable and high value building. Top-down approach consists of ‘going down’ from the ‘system’ level to the component ‘level’, passing through some sub-systems. The entire system’s functional performances are first verified and the inquiry is extended to lower levels, through analysis and synthesis of data on system parameters. The ‘bottom-up’ approach consists of starting from an installation of basic component and going up progressively to cover the entire system operation. Commissioning Provider together with the contractors executes the functional performance tests (FPT) for a system operation. Commissioning is required for all operational systems that have an impact on indoor environment conditions, user safety, energy use of building or water consumption.
