Intension In this graduation project I will make a redevelopment of the Q-Port building to a Hotel and Congress Centre: On the one hand, my project focuses on the refurbishment of an office façade into an energy producing façade. This renew has an ecological, social and economic importance. These three aspects reflect my sustainable approach. On the other hand, the establishment of a new use strategy for the Q-Port building in form of a Hotel and Congress Centre plays a key role. The Q-Port building is a bad example of urban planning when an important aspect of life – work – leads to mono-functional urban sectors. Instead of thinking in certain functional categories, I want to create spaces in the urban context in which we simply enjoy living – spaces with leeway for individuality – regardless of how large the building is. KEY Feature - “Grüne Lunge” Key feature of my design is the “Grüne Lunge”, an open public way and an energy generating technology as design element of the façade to unite the urban concept and the energy concept within the façade design. The redesign of the Q-Port building is linked to the historic urban planning strategy to be a green recreational area. Urban porosity is the key intention of the new hybrid Q-Port building with the aim of pedestrian oriented urban places. The transformed Q-Port building becomes localized a `social condenser´ for new communities: The “Grüne Lunge”, an open public space spirals upwards from the street and guides the people through the building. ReDesign The redesign is not only use related but also energy efficient with the design of an energy generating façade, which makes the building to an energy production. In the focus there is an active intelligent façade, the “Grüne Lunge”, in relation to the climate of a building and the possibility for the urban context: The façade is my fascination because it shows most dominant the architectural value of a building. It is the visible statement to the world and it gives a face to the building. Façades connect the inside space and the outside city rooms and have a high potential as multifunctional construction elements. The new task of the façade in my design is, that the “Grüne Lunge”, which is an open public way, is linked to the energy concept of the whole building and is main part of the ventilation concept. The “Grüne Lunge” is an open public way, which spirals upwards, and guaranties natural ventilation in the rooms. In the summer time it transports cold air from the north side of the building into the south part. The night cooling out of the building in the summer is done by the “Grüne Lunge”. In the winter time the air is transported from the south side of the building and is preheated in the buffer zone of the “Grüne Lunge” and flows over an air guide system in the suspended floors into the rooms. Moreover, the “Grüne Lunge” acts as an interspace and a connection point for the public and private activities within the building. Benchmark The perforated glass in the building envelope is only broken by the transparent envelope of the “Grüne Lunge”. The “Grüne Lunge” in the building`s envelope can be seen from the highway or the streets and by this people get interested in the new use strategy of the Q Port building. The new Q Port building should become a highlight building in the Brettenzone like a Benchmark for the city part Brettenzone. Therefore the installation of a media façade which offers surface for commercial activities is done in addition to the BIPV modules at the closed façade parts. This is the next step into a more sustainable future: The energy concept for the Q-Port building is able to generate energy within the façade and so unifies the energy demands of the future.
