1. 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
    
2. 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
    
3. The 2226 Operating System –  the intelligent building control system automatically regulates building temperature, CO2 content and air humidity via ventilation panels

Temperature behaviour

Temperatures inside the building run several weeks behind those outside and fluctuate much less, even with extreme changes in outdoor temperature. This slow reaction owes to the massive structure’s high thermal storage capacity.

Temperature behaviour
​​​​​​While indoor temperatures are significantly higher – a consequence of heat generated by people, equipment and lighting – they are still periodically lower than 22ºC or higher than 26ºC.

Temperature behaviour
​​​​​​​Temperatures here are a constant 22 to 26 ºC; the 2226 operating system regulates climate and CO2 content via sensor-controlled ventilation panels. Even extreme conditions are compensated automatically: a building that is very cold or temporarily not in use will turn lights on as a back-up, while night cooling is switched on in cases of extreme heat. Excessive CO2 is expelled with automatic rapid ventilation.

The 2226 Lustenau, an officebuilding 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.

Building services require just a few square metres of space.

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.
