„Plan, Build, Operate“ is both the principle and the unique feature of the Solar Decathlon Europe 21/22 with an urban focus.

The competition format comprises two challenges: In the Design Challenge, the teams design an architectural and energy concept for an existing building, including an addition or extension, or a new building for a gap between buildings in an urban

context and incorporate the surrounding area, including the socioeconomic issues and challenges anchored therein. The aim is to achieve redensification with living space against the backdrop of a climate-neutral building stock. In the Building Challenge, the teams build a representative section of the Design Challenge as a so-called House Demonstration Unit (HDU) on the event site

Design Challenge (DC)

in Wuppertal. The result is a fully functional exhibition building that combines attractive architecture with ecological construction and innovative building technology. The interdisciplinary team from Düsseldorf University of Applied Sciences brought together seven departments. The guiding principle is „Minimal Impact - Maximum Output“, or short ,,MIMO“. The contribution shows a

solution for holistically resource-efficient buildings in an urban context. Only what offers added value to the location and creates maximum benefit with minimum intervention should be done. In the competition, the team is refurbishing and extending an existing building in Wuppertal, the Café Ada. 2020/22

The project adheres to the principle of efficient expansion, aimed at enhancing the value of the neighborhood. It offers an alternative residential solution to the large „Gründerzeit“ flats. Through thoughtful interventions and the preservation of the external appearance, the existing qualities of Café Ada and the event center will be enhanced. The extension comprises 26 pre-

fabricated solid timber residential modules spread over three storeys, following a modular approach. This facilitates sustainable utilization and a cohesive material and design concept, made possible by digital planning and production techniques. With 15 residential units catering to individuals of all ages, various flat types accommodate up to 33 occupants. The modules are strategically

Intelligent facade design ensures natural air conditioning within the communal areas. The private living space is extended by the principle of „those who share, have more“.

Team MIMO‘s House Demonstration Unit (HDU) embodies the holistic vision of the Design Challenge within an 18 x 18-meter construction site completed in just 14 days.

The HDU comprises two compact residential modules and a BSE module arranged across two levels within a climate-controlled enclosure. These levels host minimalist living spaces and communal areas including

a kitchen, dining area, lounge, and versatile furniture with integrated storage solutions.

The entrance, situated within the communal kitchen area, features flexible partitions using curtains, adaptable to create distinct zones or maintain an open layout conducive to warmth. The spacious two-story central area fosters communal interaction,

14 / 4th master / master thesis

Once a central gathering point, the former Alt-Hürth swimming pool is being transformed into a vibrant space for the entire community, revitalizing the core area around Brabanter Platz. While the swimming basin will be removed, the building structure will remain, unlocking unused spaces for high-quality functions. The redesigned upper floor offers versatile

opportunities, with office spaces providing stable income through leases to regional businesses and service providers.

A carefully curated mix of uses on the ground and basement levels, including retail shops and a post office, ensures consistent activity and attracts visitors. Additional features like rentable rooms, work-

shops, and a café foster social interaction and strengthen community ties. Weekly events, discussions, and farmers’ markets integrate the building further into local life.

By preserving and carefully modernizing its historic character, the former swimming pool becomes a sustainable and unique focal point for the area.

kita mariposa day care centre Location Paucaparta, Bolivia Typology Education Design-build status Construction

360 sq m

The design-build project focussed on the creation of a pioneering inclusive daycare centre in Bolivia. The architecture and culture of the site were studied during an intensive two-week trip to ensure a sensitive integration of local influences.

The current intermediate status of one of the designs presents a structured

20 / 3rd master / design studio by Pablo Molestina / design build project

layout that divides the building site into five zones. Strategic projections and recesses create an architectural dynamic that is both aesthetically pleasing and functionally well thought out. The butterfly roof not only elegantly separates the interior spaces, but also symbolises integration into the landscape. The age

of reinforced concrete has begun in South America. The project deliberately uses local construction methods and materials to emphasise sustainability and ecological responsibility. The project contributes to a greener future of building traditions in South America.

wind catcher climate institute Location Düsseldorf, Germany Typology Education

The project is dedicated to the planning of a climate institute based on the innovative integration of the physical element of thermal inertia. Thermal inertia refers to the ability of an element to store absorbed heat and gradually release it into the environment. The basic idea is to create two structures - three

22 / 1st master / design studio by Philippe Rahm

wind tunnels with low thermal inertia and four functional buildings with high thermal inertia. The wind tunnels serve as access routes and meeting points, provide natural cooling in summer and generate heat in winter as part of the greenhouse effect. The functional buildings act as efficient heat stores in

winter and cold stores in summer. The concept combines different thermal properties, optimises the institute‘s energy consumption and creates a harmonious symbiosis and interpretation of the physical element.

konos stool made from wooden slats Function Stool, Table

26 / 3rd bachelor / furniture manufacturing

The Konos stool (derived from the ancient Greek κῶνος kōnos cone) is characterised by six tapered modules that are connected to each other. Each module consists of four elements that taper by a subtle value. The multiplication generates a depth that emphasises the refinement of the design. The stool can be used not only as a seat but also as

an ideal side table. The lightness of the Konos is visualised in particular by the delicately tapered diagonal supporting element. It functions as a shelf when used as a table. A functional piece of furniture for a wide range of applications.
