About the team
RoofKIT is an interdisciplinary team of architects, designers and engineers. It’s a collaborative think tank that will grow over time and include more individuals and organizations along the way. An intensive collaboration between student team members, professors and supporting firms enriches our competition entry. A student core team is responsible for the project management and the coordination of different professions.
As the building sector has 50 % of the primary energy consumption worldwide and uses 50 % of the primary raw materials, there is no possibility to go on as always. Something has to change, and team RoofKIT will make proposals how to shift towards a sustainable building sector.
Due to the climate change, we need to rethink architectural approaches, question our actions and ultimately build differently! As the building sector claims 50 % of the primary energy consumption worldwide and uses 50 % of the primary raw materials, there is no possibility to go on as always. Something must change, and team RoofKIT will make proposals how to shift towards a sustainable building sector. Therefore, one main aspect is the conversion of the common linear to a new circular economy. Developing innovative constructions and rethinking the usage of materials dominate our working process. These aspects are not confined to new buildings, but also include dealing with existing structures, which leads to an improvement in terms of energy consumption and urban integration and thereby enhances longevity. Creating sustainable and renewable buildings is our passion, because: We want to change the world! To put it roughly…
Urbanisation in Europe reached approximately 75%, and the tendency is growing; thus, European cities face several urgent problems, which should be solved to comply with the EU targets to fight climate change. Due to the current living space shortage in Germany, the rising emissions, the resource scarcity, and the huge waste generation, RoofKIT intends to tackle these problems in a holistic manner using rooftops which represent a remarkable share of the unused area in cities.
RoofKIT does not only create new living space by topping up the existing structure of Café ADA, instead, the historic building becomes an integral part of the design concept. Roof-KIT‘s goal here is to take up the local potentials of the site and neighbourhood and improve it together with the building design by creating synergies. The current utilisation as café, ballroom and accommodation will be strengthened by giving them additional spaces. The ball room is shifted one floor upwards to the newly created urban gap, which forms a transition between the existing structure and the extension.
Due to the visible structure and a glass facade, the ball room is now connected to the urban context. The space thus gained on the second floor is used to establish accommodation for international artists and visitors. Built-in windows will be energetically improved by a second layer of windows from the urban mine. Crossed wooden trusses span the entire length of the building and rest on an outer circumferential truss in the urban gap. Prefabricated wooden modules are assembled on the Urban Gap and allow a quick and simplified assembly on the construction site.
In Germany, the average number of persons per household is dropping constantly, resulting in an increasing consumption of average living space, which inevitably leads to a higher waste of resources. To counteract this effect, the extension applies a concept of shared spaces to reduce the provided individual space, while still maintaining a high comfort. The private living units are arranged around an atrium in joint use. Between the apartment modules, there are commonly used rooms as laundry, storage and reading rooms. The modular living units address the different needs of residents in a variety of living situations, including students, families and seniors living together in social mix.
A compact house demonstration unit developed from the south-western part of the top floor shows outstanding sustainable design solutions, especially in terms of space efficiency. The unit consists of three modules with a central core, which bundles all technical installation, as well as the kitchen and the bathroom. Besides, a functional wall is added as an additional layer to the wall. Thus, the freely usable space of the unit remains nearly the whole net floor area.
