Klimahaus® Bremerhaven 8° Ost Interactive Exhibition Bremerhaven, Germany Client: BEAN, Bremerhaven Operator: Klimahaus® Betriebsgesellschaft Project Management: StäWoG Architect: Klumpp Architekten, agn, Niederberghaus & Partner Structural: ARGE Prof. Bellmer Ingenieurgruppe © Jan Rathke / Klimahaus® Bremerhaven 8° Ost Mechanical: (LP 39) Schmidt Reuter Completion: 2009 GFA: 20,000 m2 The architectural design for the visitor´s attraction is a transparent, sculptural glass envelope wrapped around the internal concrete structure. The houseinhouse concept hosts approx. 15,000 m2 of exhibition area and handson experimental spaces. "The Journey" takes the visitor on a trip around the globe, exhibiting him to the specific conditions of Climate zone Antarctic distinctive climatic zones of the world as extreme as arctic polar, tropical humid and hot dry desert climates. These conditions are realistically reproduced on approx. 5,000 m2 of successive rooms and spaces. A climate and energy concept around the exhibition and experimental areas such as "Elements", "Perspectives", "Opportunities" and the foyer as well as the aquariums has been developed and implemented in an integral planning process. In this process the entire design team from architect and exhibition and media designers to MEP planners, structural Climate zone Niger engineers and building operation managers were to be integrated to coordinate a wide range of individual requirements and advance from compromise to synergy. That way a fully natural strategy for cooling and ventilation based on local climatic potentials, including geothermal energy, could be implemented for the majority of the spaces. A building integrated Photovoltaic system was desgined to provide both shading and renewable electricity production of the glazed central arrival hub. Climate zone atmosphere The developed climate and energy concept emphasizes the aims and motivations of the project which are to promote responsible behavior towards the environment in addition to serving educational purposes. Climate concept © TRANSSOLAR - www.transsolar.com Cloudscapes Karlsruhe, Germany Architect: Tetsuo Kondo Architects Mechanical: TRANSPLAN GFA: 7,000 m2 Peter Weibel, director of ZKM in Karlsruhe and curator of the exhibition "GLOBAL DIGITAL", sees a manmade cloud in an enclosed space as an example of the exoevolution, meaning of the manmade evolution. Cloudscapes created by Transsolar and Tetsuo Kondo, is therefore one of the two openingexhibits, a 300day exhibition for the 300year anniversary of the city of Karlsruhe. In two connected atriums covering a space of 7000 m2 the moving clouds and sea of clouds communicate with the historic structure of the Center for Art and Media (ZKM) Karlsruhe. The clouds and the climatic conditions for artificially generated clouds can be perceived by using a ramp and a tower construction that lead into the clouds, on the second building level the visitor can be "above the clouds". Creating indoor clouds causes high energy demands relating © © www.fotografieboese.de to the energy that drives the forces of our atmosphere. Initially inconspicuous changes in temperature, humidity level, or air movement have huge impact on the appearance of the man made cloud in the museum. This symbolizes what influence current environmental interventions must have only on a larger scale and how we treat our sensitive planet. © © www.fotografieboese.de © © www.fotografieboese.de © TRANSSOLAR - www.transsolar.com Cloudscapes Architecture Biennale 2010 Transsolar KlimaEngineering + Tetsuo Kondo Venice, Italy Client: La Biennale di Venezia Completion: 201008 GFA: 800 m2 Transsolar installation “cloudscapes“ designed in cooperation with Tetsuo Kondo was a walkable cloud visualizing climate engineering. A floating cloud inside an enclosed environment can be accomplished by creating positive temperature stratification, where the air temperature significantly increases with height. Vapor and water drops are released into a layer of air in the middle of the space until it is saturated beyond the point of condensation, and the cloud begins to ‘materialize’. Contrary to intuitive perception, humid air is lighter than dry air, so the cloud will not fall to the ground. On the other hand, the air above the cloud is even lighter due to its high temperature, keeping the cloud stable, floating between two pillows of air of different densities. Creating a cloud under laboratory conditions is one thing to do the same in the historic, seven hundred year old Corderie del Arsenale, is quite another. The 900 m2 installation space needed to be isolated from the remaining exhibition and the outside to maintain stable microclimatic conditions. Air tightness turned out to be key and aerodynamic turbulence around the columns a phenomenon to be controlled. A set of heat pumps and fans driving 30.000 m3 of air per hour connected with flexible ducts were hidden behind a false wall. Thermal energy was extracted from the air, cooling the lowest air layer, and transferred to warm air that was then introduced into the top layer. The conditioned air was equally distributed throughout the entire space without creating turbulence. A railroad track running through the Corderie was used as an underfloor plenum supplying cold air into the lower space, slender textile tubes above the cloud distributed warm air along the entire ceiling, providing energy to the air pillow above the cloud without disturbing the temperature layers. Parallel to the textiles moisture was fed into the cloud by providing hot vapor via small openings in copper pipes. Condensation seeds locally placed amplified the cloud formation, allowing for dynamic and tighter control of the visual appearance.

Euro The pavilion represents a beautiful integration of nature and architecture: A wooden building rests on a long, slender concrete plinth and contains a piece of dense Austrian forest. The idea to produce good air quality came from Team.Breathe.Austria and the climate engineering experts Transsolar. The forest project for the Expo pavilion demonstrates a selection of outdoor comfort design strategies by transporting the visitor from hot, urban Milan to a cool Austrian forest within a matter of steps. A visitor exits the hot, crowded roadway and gently ascends into the lush vegetation in the pavilion. The air is noticeably cooler due to the shaded environment. The deeper the visitor penetrates into the pavilion, the more intensely this cooling effect will be felt. To reproduce the sensation of being in a forest, an active evaporative cooling system with complementary forced air is used. Sensors embedded amongst the vegetation allow precise control of highpressure nozzles and fans which allow the production of fine ground level mist or cool air curtains. The fans are juxtaposed with the trees, deliberately exposed to the visitors. These active strategies were designed with the support of a Transsolar thermal simulation tool. This tool allowed the Austria pavilion team to predict outcomes of various climateconditioning measures and refine their design and implementation. Although Transsolar mainly applied active measures for this pavilion, the project is sustainable and energyefficient: The total energy demand of the pavilion, including electricity requirements for artificial lighting, a cafeteria, highpressure nozzle systems and fans, is generated by a roofintegrated photovoltaic system (41 kW) and a Grätzel cell (flexible PV) sculpture with (1.6 kW) on the roof. Of course, the trees play a role in sustainability too: The project initiators calculated they produce 62.5 kg of oxygen per hour which is the oxygen requirements for 1800 visitors breathing for one hour. © TRANSSOLAR - www.transsolar.com Theatrical complex “Theaterhaus” Stuttgart, Germany Client: Theaterhaus e.V.

Adrian Pcanschi Mechanical: piv.Planungsingenieure Completion: 2003 GFA: 12,200 m2 Costs: 17,9 Mio. € A main aim of this project was to create optimal areas for artists. Apart from energetic and ecological criteria any impairment of the artists by noise or air draft due to air conditioning systems was to be avoided. In view of the close budget and the boundary conditions determined by the monument protection and the idea of the naturally ventilated © Dietmar Strauß theatre was born. During the long development process of the project the concept had to be adapted due to changed boundary conditions, but still exists in its central components. The fresh air flows under the building in channels to the different halls. The channels have no insulation to the adjacent soil and work heat exchange compensatorily on the supply air temperature, in the summer the air is precooled, in the winter preheated. Air pours with low speed into the halls, collects itself on the ground and rises up slowly as soon as it warms up. Under the hall roof the air flows over channels into the high rising exhaust air stack outwards, by stack effect, which is © Dietmar Strauß caused by the temperature difference between inside and outside. In wintertime a part of the heat which is contained in
