Risk management for planning and use of building service systems

The design, use and maintenance of buildings and building service systems have become more and more complex, in the sense of management of information and knowledge. The systematical risk management methods and applications are sophisticated ways to evaluate and manage the risks. This paper presents three case studies for risk management. The first case describes the management of risks and success factors in building service life-cycle project, and this is application for design phase. The second case describes the systematic approach for risk management of indoor air quality of ventilation system during the use of system. The method points out the biggest risks inside the system, which may cause problems in indoor air quality, and will help to find out the most important points in the technical system, to be checked and controlled. The third case is evaluating the risks when taking the responsibility of energy consumption of the building service system.
