Commissioning of a Building

When a building or refurbishment project is closed, planners, building engineers, architects and craftsmen often leave the construction site. They hand the building over to a facility management and users who have not been involved in the prior planning and construction process at all. Therefore, they extensively have to be informed about how to use the building adequately. If the handover and commission process does not run smoothly, a low satisfaction level of the users is bound to occur. This leads to a decreasing general acceptance of sustainable building and refurbishment. The commission process can last more than a year, also due to challenges that change with the seasons. The requirements for winter operation are totally different from the tasks facility managers have in summer. During this process, the facility management has to be introduced in the correct operation of the facilities. Within that stage, measurements on the achievement of goals are also conducted (e.g. air quality measurements). The building users need instructions, too, and if comfort losses occur, they need contact persons. The facilities should match the needs of the users and an individual adjustment should be possible.

A successful commissioning can lower operational costs by 20% and increase user comfort – and therefore their quality of life – significantly. This has a positive effect on the acceptance and image of sustainable buildings in general.

The following movie shows, using the example of buildings in Vorarlberg, how the CESBA tool has been implemented:
