The desire for environmentally compatible, energysaving buildings where users feel comfortable requires new approaches to climatisation concepts.

In line with the motto "less often is more", the objective pursued is to achieve more functionality using less technology. This is done by regarding the building as a total system that interacts with its environment. For example the facade, the structure of the building and the technical plants of the building interact with each other.

Within the context of the building climatology approach, the objective is to exploit available natural resources and to match the facade, the building structure and the technical plants of the building optimally to each other.

Here the primary emphasis is on optimisation of the facade´s energetic properties, activation of the building´s storage masses and maximum use of natural lighting and natural ventilation of the building´s rooms.

Building simulation is an important tool for the development of innovative climatisation concepts. It enables to predict the influence of the complex interactions between the building and it´s environment, in order to develop an optimal solution which fulfills the requirements of investor and user. Various potential solutions can be evaluated, compared and analysed in terms of their cost effectiveness. Furthermore innovative solutions and the utilisation of regenerative sources of energy can be investigated with regard to their functionality and cost effectiveness under the prevailing general conditions and constraints.
