2 Transsolar Energietechnik GmbH Technologies for energy efficient design and thermal comfort in buildings Foundation of the Company: 1992 Employees: 30 Offices: Stuttgart - Munich - New York Stuttgart 20 engineers New York 2 engineers Munich 6 engineers # 2

3 Taking advantage of natural sources, like Daylight Cooling potential of the cold air at nighttime Cooling potential of the ground Energy potential of solar radiation Taking advantage of physical effects, like Wind / Chimney effect to provide natural ventilation Radiation to create thermal comfort Stratification and thermal zoning Integrative solutions to get synergy effects and economical solutions, like using building construction for climate purposes using atrium, columns,... for air distribution Climate Engineering High comfort - Low Impact Basic Approach # 4
