The traditional planning process is still based on the concept of static building, where the completion of the building represents the last horizon. At that point however, the final energy, mass and monetary assets as well as output of emissions cannot be established. These assets progress constantly throughout building´s lifecycle and are caused by its multiple changes and mutations. The ratio between the consumption of resources and the output of emissions in the manufacturing phase and the latter phases such as use and re-use is 20%:80%. This ratio implies that the early planning phases such as pre-design and design phase are of crucial importance. These phases are of short duration (few months), but determine the future performance of the building throughout the long phase of utilisation (up to 80 years). Moreover, in these phases the change potential is still almost indefinite, while the changes in the latter planning phases are related to the significant increase of the construction cost and due to this fact often impossible.
However, buildings must not only fulfil the ecological premises; their original function is the one of the shelter; further on the container for certain social use (school, housing, etc.) as well as the cultural expression of the society.
This paper presents the strategy and the evaluation tool for designing, planning and management of flexible, dynamical buildings, which are capable of absorbing different changes in terms of sustainable development, guaranteeing social, economical and ecological optimum throughout their life cycle.
