The concept of 2226 is to provide a building with a comfortable range of interior temperatures (22oC to 26oC) without any heating, air conditioning or mechanical ventilation. The temperature range is guaranteed by a combination of thermal mass and natural ventilation, using the heat emitted from the bodies of the users and the office devices as energy sources. The concept has been applied to buildings in different locations and has since become a standalone research and development program within the Baumschlager Eberle practice, but here the focus is on the first example building of the series, built in Lustenau.

The project is an extension of a 1950s office tower in Berlin with a twofold goal: to reconnect the isolated tower with the (current and historical) city fabric and to become a prototype of exemplary energy performance for office buildings. The new connection to context is achieved through a heterogenous composition of volumes that take cues both from the baroque layer of the city (plinth) and from the late modernist layer (slab). The energy performance concept is based on a double skin concept and an aerodynamic ventilation fin at the top of the slab.

The C10 Tower was originally built in the 1960s. In 2008 Staab Architekten undertook the refurbishment and renovation of the building, with a focus on building performance.

Frederiksbjerg School in Aarhus, Denmark, aligns with the principles outlined in the 2013 Danish school reform. The school supports dynamic learning through movement and sensory exploration while emphasising openness and community spirit. The school has become a central hub for local children and youth. This deliberate design fosters individual and community wellbeing and nurtures a strong sense of togetherness among students.

The ‘Zero-carbon Cultural Centre’ in Pakistan, designed by architect Yasmeen Lari, represents an exemplary fusion of sustainability and cultural preservation. This visionary project combines traditional techniques with modern innovation, creating a carbon-neutral cultural hub. It exemplifies the harmonious blend of sustainability and cultural heritage and carries profound social impact. By revitalizing traditional craftsmanship and promoting eco-awareness, Lari’s creation fosters community engagement, empowerment, and a renewed sense of cultural pride, transcending architectural boundaries.

An outdoor market organised around an ancestral tree that has become a public space. The project design references the area’s traditional market architecture of adobe posts and reed roofs, pushing the typology forward using compressed earth bricks and metal for durability. It results in an infrastructure that is visually appealing that the users can be proud of, and that has the potential of consequently attracting more people and activities to the area. The design of the project is kept very simple, using a colourful recycled metal canopy produced through a succession of individual shading structures that compensate for the difficulty in growing trees in such an arid, desert climate.

Perched on the Rokko Mountain in Kobe, the Rokko Shidare Observatory is a unique landmark that not only takes in spectacular views, but also provides a place to experience the natural energy and beauty of the Rokko Mountain. A key visual feature of the observatory is the 16m diameter meshed dome that provides partial shelter against the weather.

The school is an impressive example of a hand-crafted endeavour, highlighting excellent principles of sustainable design and architecture that resonates with the community. By skilfully integrating tradition wisdom, easily accessible renewable resources, and innovative building methods, the project preserves its traditional identity while also welcoming contemporary elements in its appearance and function. The school (for 168 students) adopts an alternative child-directed work method over conventional frontal lessons. Mirroring this philosophy, the two-story school architecture offers diverse spaces for children’s activities, aligning design with the educational approach.

The Gando Primary School was built to expand the sparse network of schools in the province of Boulgou, in the east of Burkina Faso, and addressed two characteristic problems of many educational buildings in the area: poor lighting and ventilation. In order to achieve sustainability, the project was based on the principles of designing for climatic comfort with low-cost construction, making the most of local materials and the potential of the local community, and adapting technology from the industrialized world in a simple way. Underlying the project was a strong didactic component: it was designed as an exemplar that would raise awareness in the local community of the merits of traditional materials, updated with simple techniques that would need few new skills. The school building includes three volumes, each containing a classroom measuring 7 x 9 metres, connected by a single roof make up the basic structure of the building, and each one of them accommodates one classroom for fifty students.
