2226 Building

The 2226 concept is a pioneering contribution to the architectural questions of our time. Challenging the prevailing dictum that energy efficiency is only possible with highly complex building technology, it does without these systems entirely by relying on the basic means of architecture instead.

That promise is delivered exclusively with basic building physics: solid walls and ceilings that serve as insulating and storage masses; a balanced interplay of façade and window surfaces, proportions, materials and light. Another key component is the building control system, which intelligently monitors indoor and outdoor conditions and regulates the temperature accordingly.

A 2226 building makes without heating, ventilation and air conditioning. It is heated with the warmth generated by the people in its rooms, its technical equipment and lighting. Sensor-controlled ventilation panels adjust temperature and CO2 levels as needed, ensuring a pleasant indoor environment in any season.

Another stand-out feature of this concept is its excellent return on value and reduced construction costs, energy efficiency and life cycle costs: doing away with conventional building technology eliminates the need for planning, procurement and maintenance while ensuring that operating costs are kept extremely low.

2226 buildings also benefit from a timeless aesthetic, high-quality materials and usage-neutral surfaces, all additional factors contributing to their sustainability.

The 2226 building itself – clever architecture with a solid structure and the high thermal storage capacity that goes with it, coupled with temperature-compensating materials and surfaces

The 2226 building use – the people for whose well-being the building was designed and who, together with electrical devices and lighting, also serve as a source of heat

The 2226 Operating System – the intelligent building control system automatically regulates building temperature, CO2 content and air humidity via ventilation panels

The 2226 Lustenau, an office building completed in 2013 – quantifies the concept’s efficiency benefits in concrete terms. 2226 Lustenau is highly energy efficient, but it also sets new standards in cost- and space efficiency as compared to a standard building.

With 45 kWh/m2, its annual energy consumption is reduced to one-third.

Further criteria for a stable, sustainable investment include more than just traditional construction methods and materials that have been tried and tested for generations; a building also needs a certain neutrality of use. Open floor plans between the façade and the service core at the structure’s centre enable easy adaptation for any number of scenarios.

Life Cycle Costs (50 years) of a 2226 building are half those of a standard building.
