Potentials for optimizing the quality assurance of air conditioning systems from the planning process to commissioning

Potentials for optimizing Copyright: EBC Comparison of the idealized and traditional building process

The context of this thesis is to investigate the current planning process of air conditioning systems (HVAC) by evaluating the existing process from the determination of basics to the commissioning. The traditional planning process will be explained and evaluated to help form a new more idealized process.

Based on a review of current research, literature and through analysis of interviews with different project participants the weak points and failures of the current planning process are identified. For the weak points mentioned, possibilities for improvement are described, which are finally summarized in an idealized planning process.

The investigation showed that most problems occurred in the planning phase and that the evaluations of employer’s requirements were not sufficient. One of the fundamental failures of the current process is that demands of the client are not thoroughly investigated leading to belated and costly changes in strategy and execution.

Additional errors caused by interface problems impede the planning process and effect the execution phase. The required strategy and process needed to implement air conditioning plants correctly is dependent on various systems of building services (BS). Often failures in communication between members of the project result in information loss in meaningful planning documents.

Successful use of commissioning management and building information modelling (BIM) result in significant reduction in planning process failures and help to form a more idealized planning process.
