commissioning

This paper after its first chapter about commissioning, presents the methodology used in the first re-commissioning phase of the CAMET HVAC system, with its principles and facts.Commissioning is a unique opportunity, for all partners concerned, to learn a lot about the realbehavior of a HVAC system and to restore people's confidence in air conditioning.

This paper is a presentation of a concept for a new automated tool that uses the capabilities of Building Energy Management Systems (BEMS). Some parts of the commissioning process can be automatized and can generate benefits over the whole life of a building.

A satisfying building commissioning depends on both using right models and using models right. Through 3 case studies, this paper shows how to use simulation models correctly, to commission HVAC systems.

This paper presents a tool for manual commissioning of air handling units with the idea to combine the measurements with simulations. Thus the value of the measurements will increase.

This paper points out the importance of control system in the overall operation of buildings and gives a description of practical issues in association with modern IT-oriented control systems.

Air conditioning equipment commissioning adjusts the variables of air diffusion, induction ratio and Coanda effect to optimise comfort. Outlines the author's views on employing suitably qualified persons for commissioning, and in the case of larger projects, a commissioning manager. Recommends the use of a hood factor for air balance and system leakage diagnosis. Lists methods available for balancing water based systems, with index balancing being the most cost effective. Recommends also conducting pre-commissioning checks.

Describes the post-construction HVAC system commissioning process done at a new historical museum and archival storage facility. Improper functioning of HVAC was discovered. The building was commissioned after occupation. The paper describes the process of rectifying the problems, and emphasises the importance of employing a commissioning agent throughout the design and construction process.
