Innovative bioclimatic architecture in Germany is typically used by the private, business-driven economy, which is where this conviction arises. As a society, whose buildings as a whole are concerned, it is taxpayers' money and its prudent use which always poses limits to production costs when compared with the observance of long-term operating and maintenance costs. Major buildings, an exception here, are created by public builders for which limited resources and relative virtue allow for creative innovation.
In the case of the school diner in Ilsede, Germany, it is of the utmost importance to serve as a didactic example for the growing post-fossil generation, and as challenge to enhance their forthcoming post-fossil future. The completion of the Ilsede school diner projects itself as mediating a final element of the last century’s conglomeration. Volumetric slices from the developed concrete whole are rhythmically placed to harmonize with the surroundings: low towards the residential neighborhood and high towards the school campus.
As the building fits this typology, the restriction on passive measures presents itself within its completion as the opening to the southern park: capturing the southern sun for the primary means of thermal conditioning, and the optimized capture of cost-saving daylight.
Archi-tectonic practices remove the project innovation from the tradition of the construction phase of its ancestors. Components form a building complexity within the means of simplicity: fairness and modernity create a light enriched culinary hospitality. A limited, precise material palette requires a precise mode of construction. The use of metal, wood and acoustic materials create a thermally sound concrete outer shell, which shapes the interior. With concrete in a sustainable, simple and more efficient and holistic prefabricated application, the sophisticated thermal performance expectations increase. The central mediating form functions as follows: it bears, wraps, and transports light and thermal stores, as well as opens and closes infinitely, allowing view relations which invite one to linger. The concept of a warm thermal core enclosed within a porous shell creates the framework of a multifunctional cafeteria / classroom / meeting room within the school and beyond for the community and society.
