The aim of this research is to study the possibilities of adaptation in a façade in order to be able to design an adaptive façade for the future faculty of Architecture at TU Delft. In general, an adaptive façade has the ability to change, responding to changing internal and/or external climatic conditions influencing room comfort. It was evident from the beginning of the research that an adaptive façade can have a positive effect on a building’s energy consumption and comfort. The idea that an adaptive façade can contribute to a flexible building and usage of space as well, is quite new; it assumes that this type of façade is necessary to fulfill the different requirements per room type placed on the internal climate. To verify this, three room typologies – a design studio, an office and a meeting room – have been researched on their user and climate requirements. An understanding of the difference in use of both the room and its façade (for instance practicability of the façade), and the related comfort requirements per room typology is necessary to comprehend the effects on the façade. The study on comfort shows that light and ventilation need to be adaptive because every room type has different comfort requirements. The usable floor area per person is different per room type and the reverberation time varies as well, but this difference is solved cleverly by using materials with different absorption qualities in the room itself. A difference in temperature, light, ventilation and sound all have influence on the design of the façade and the internal climate. The relevant internal factors influencing room comfort are people, electrical devices and lighting. Their effect on the internal climate differs per room typology since the amount of people and the surface area vary. The external conditions – solar radiation, outside air temperature, humidity, precipitation and wind – are dependent on location and orientation and cannot be influenced by design; however, an adaptable façade must make best use of these conditions. The amount of adaptation needed in a façade is analyzed in the adaptivity analysis. The analysis takes into account the different functions, day and night differences, the seasons and the façade’s orientation. Different profiles have been defined to study the effects of the different adaptive functions in relation to each other. Furthermore, different levels of adaptivity have been quantified to research what function needs what amount of adaptation, the levels being: minute-to-minute, day and night, season and years. These levels are necessary to limit down the choice for certain components even more. To be able to actually design a façade with adaptive components, one needs to know what is there and what is not. An overview has been made for façade components that can adapt manually, mechanically and on a material level – so-called ‘smart’ materials. Of course, this overview is not complete and probably never will be, but within the timeframe of this research, it does tell what the potential of the component is and its advantages and disadvantages. The components have been organized per function into a diagram. In combination with the defined profiles for designers it’s a useful tool to create new façade concepts. Three different concepts have been worked out with the help of the profiles and the diagram with adaptive components. These adaptive concepts show the possibilities, effects and restraints for the future façade with adaptive components. The last chapter shows the result for an adaptive façade design as a result of the graduation assignment in both architecture and building technology. In conclusion, adaptivity in a façade is dependent on a lot of different factors: the user profile and practicability of the façade; its effectiveness in time, meaning the different levels of adaptivity; its climate profile; its costs and architectural choices. It is also a direct outcome of what components are available at the time of making the concept and design. The future façade will potentially take in more and more functionality, with a better integration of building services and integration with a building’s structure.
