Renewable, recycled, recyclable and innovative materials

Rainwater collection, solar energy with integrated PV modules, wind turbine, island mode electricity supply, ground source heat pump, triple glazing, passive house level insulation, coldbridge free construction, usable flat roof, (U walls: 0,148 W/m2K, U roof: 0,086 W/m2K). Buffer zone floor plan, heat recovery ventilation, automated solar control with louvres. Graphite insulation, YTONG walls, Internorm windows.

Key Sustainability aspects
solar building integration, accessability for disabled, recycling and reuse, innovative bulding materials, integrated planning process, participation of users in planning process, use of innovative design tools, zero energy design
Social and ethical responsibility

Excellent indoor  air quality, acoustical and thermal comfort. Accesible for disabled persons. Workplace creation in the rural area.

Ressource efficiency and environmental impact

Minimised environmental impact, ultra low energy design, passive house standard construction, extensive use of renewable energy. No chimney, no emission, zeroCO2 and netzero energy project. The north facade is almost completely closed, the walls are curved to reduce geometrical coldbridge and wind turbulence.

Economic lifecycle perfomance

No need to use gas, no need to invest in gas pipes. Only electricity is used, partly generated on site. The building is partly self sufficient, capable of limited autonomous operation. Only long life good quality materials used. Good payback period thanks to the minimised public utilities cost.

Contextual performance and impact

The project is built in the countryside, where there is no public utility connection. The high standard office building operates partly autonomous. Architecture fits in the high tech bridge image.

The project received the "Most sustainable project" title in 2008 in Hungary. The example resulted a 4000 sqm OMC and office development with similar quality.
