| Abstract |
Due to its long technical lifetime a building must be flexible in order to be able to cope with qualitative and quantitative changes in demands. The added value of flexibility is the ability to adapt the building to changing market or user demands, the reduction of the risk of future vacancy, lower adaptation costs of buildings-in-use, higher rental income, happier users, a longer lifespan and as such a more sustainable building. A potential risk is that costly provisions made for future adaptability will not actually be used in a given period. This chapter explores the concept of adaptive capacity, which can be split into three different factors: organisational flexibility, process flexibility, and product flexibility. A first version of a method to define the demand for and to assess the supply of adaptive capacity included 143 indicators. To make it more practically applicable a light version (called Flex 2.0) has been developed with the seventeen most important key performance indicators. |
