Life cycle models in building services technology

Customer-focused life cycle building service technologies are changing the operations and networks of companies. New requirements and value-creating mechanisms fall extensively in
the various fields of business and in different stages of projects. Effective utilization of life cycle models requires new know-how and the ability to verify the added value from both the client and provider alike. Output-based procurement methods affect the risk transfer and the combination of tasks in a new way. Competitive procurement procedures and output-based long-term contracts bring about new options. Additionally, international consideration has broadened the views on development. The five life cycle service models developed within the Life Cycle Models in Indoor Environment and Building Services project (CUBENet) are based on an options selection framework, which also provides a platform for further development of these models. Tools supporting the implementation of the models promote their usage.
