  5. climate – even in extreme alpine conditions

  6. Example energy base Some details from an innovative passive office building

  7. ENERGY base South facade Main issues Energy efficiency Passivhousestandard User‘s comfort thermal, hygric, visual comfort Use of renewable energy Solarenergy and geothermal energy ecology Light weight wooden exterior wall, use of ground water for toilets Passiv-office building 7.500 m² usable floor area For offices, research and educational institutions dealing with renewable energy www.energybase.at ENERGY base Giefinggasse 6, 1210 Wien

  8. Cell offices, north Openaisle Archive and auxiliary space, variable width, depending on site botanical buffer Open office space, south 3 storey void space Solution plan – floor plan, zoning section

  9. Energy efficiency: Passivhousestandard, retaining of heat Passivhousestandard: 1.Retaining of thermal energy, minimizing the losses 26 cm thermal insulation,triple glazing Ventilation system with 75% heatrecovery Airtight envelope/no unrwanted infiltration of air Avoiding thermal bridges 2. Solar gain Lüftung mit Wärmerückgewinnung 75% 25% 30 m³/pers. Necessary ventilation rate

  13. Better architecture for better comfort year:I-office2 year:I-south2 Outside temperature Outside temperature Operative Temperaturen der Zellenbüros Nord in Abhängigkeit von der Außenlufttemperatur - operative temperatures of cell offices north in reference to the exterior temperature Operative Temperaturen der Bürozone Süd in Abhängigkeit von der Außenlufttemperatur - operative temperatures of south office area in reference to the exterior temperature Operative inside temperatures

  15. uncomfortable - Air humidity Sunny research Behaglich noch behaglich – still comfortable uncomfortably dry Standard building - Air temperature Eco-humidity by plant generator

  17. Cross border cooperation?

  18. Cross border cooperation Can be that Slovakian Investors look for Austrian consultants for green-building-design and project controlling. Slovakian Planners look for Austrian partners as consultants for eco design Austrian architects look for slovakian partners To run high quality planning for projects in South-East-Europe Austrian Architects look for high quality and affordable price building components and services

  19. So let´s start building cooperations Construction site energy base Vienna, Arch. pos architekten
