2 Passive houses Wolfurt, western Austria Architect: Gerhard Zweier Heating demand < 15 kwh/m²a 3 panes glazing, cm thermal Isolation Ventilation 80% heat recovery Solar and biomass heating system BEE Aufstockung,

3 Motivation Munich Reassurance Company Munich/Germany Architects: Baumschlager Eberle m² high level offices Refurbishmant in urban context 3 panes glazing, double facade with inbetween shading system U-Values ,25 W/m²K Floor heating + cooling system Ventilation 80% heat recovery High challenges on user comfort, ecology and image BEE Aufstockung,

4 Passive house international teachers and students home, Vienna Architects: P-ARC, Vienna 180 flats, new building in urban context 3 panes glazing, high isolated concrete facade High efficient ventilation system, preheating/-cooling via ground

5 Window and isolation, details

6 Window and isolation, construction site

7 Ventilation and heating system, plan of 2 flats

8 Ventilation and heating system, construction site

9 Eberswalde regional government center, near Berlin/Germany Architects: GAP Berlin m², mainly offices New building in urban context 3 panes glazing, leight weight wood facade Special atria as climatic buffer zones Gold for energy efficient and ecological buildings in Germany 9

10 2226, Lustenau Architects: baumschlager eberle App m², mainly offices No heating, ventilation or cooling system Natural regulation trough automated windows, cooling through nightventilation. 10

11 i + R Lauterach, administration building Architects: Dietrich Untertrifaller Architekten ZT GmbH 4400 m², mainly offices LEED Platinum certification 9 kwh/m²a for heating High usage of natural light Geothermal energy for heating and cooling 11

12 Energy demand per person worldwide [kg oil equivalent/person] Qatar United States Austria China Mongolia Eritrea Ibo Kongress

13 Increase scenario [Mt CO2] % Actual values 2011 Increase, if (only) China develops as OECD now World OECD China Others OECD = Organisation for Economic Cooperation and Development (Including 34 Countries: US, Australia,Japan, South Korea, some European Countries, ) Ibo Kongress

15 Coal power station Ulan Bator Ibo Kongress

16 Air pollution from coal firing, traffic and industry, Beijing

17 Health? Ibo Kongress

18 Eco Cities, Green Cities, how will they behave in future?

19 How to build a new building? How does the process go on? How much may the building cost? How long will it sustain? How fast must the construction go on? How much energy will it need, and how much comfort? How to export well done building systems, is that possible?
