Introduction In many modern cities designed public spaces impress with their appearance but not their functionality. The project Nowy Targ Square in Wroclaw is an example of architecture that certainly delights with its modern appearance, winning many awards. However, residents do not share in the admiration of this place. The emptiness of this sea of concrete makes Nowy Targ Square unfriendly for social interactions. The main problem is the lack of shade during
summer heat. Our idea as architects was to design an interesting space in the urban fabric, that encourages human interactions in public spaces, by providing better infrastructure, shading and an improved microclimate.
CHAPTER XX
To resolve problems in empty concrete squares such as no shading, summer heat, unfriendly space for social interactions, we would like to design adaptative architecture. Wrocław is located in south-western part of Polnad. It’s the hottest city in country, with the longest growing season. Temperatures in the summer reaches over 30 degrees, which makes being on the square unpleasant. FIGURE 2: Location

Shape Memory Alloys Shape Memory Alloys is an alloy that “remembers” its original shape and that when deformed returns to its pre-deformed shape when heated. SMAs have found applications in many areas due to their high power density, solid state actuation, high damping capacity, durability and fatigue resistance. When integrated with civil structures, SMAs can be passive, semi-active, or active components of constructions. Though most of the research activities of SMAs’ applications
in civil structures are still in laboratory stage, a few have been implemented for field applications and found effective. Most obvious application of the material is a sun-shading system, that controlls the ammount of sun passing through depending on temperature. By heating the metal during the assembly, it’s possible to pre-tension it, resulting in extremely strong

Doris Sung’s projects became inspirations for the pavilion. Currently, she is working on developing smart thermobimetals and other shape-memory alloys, unfamiliar materials to architecture, as new materials for the “third” skin (the first is human flesh, the second clothing and the third architecture). Its ability to curl when heated allows the building skin to respond for purposes of sun-shading,self-ventilating, shape-changing and structure-prestressing.

Urban Urchin Urban Urchin is a project that proposes a new outdoor culture for Holon and for Holon residents. The geometry is determined by the performance of the thermobimetal attached to its underbelly, relative to the moving sun over the course of a summer day. Curling when heated, the thermobimetal canopy is designed to perform differently depending on its location on the surface. Near outer edges, the thermobimetal tiles filters the sun to filter the amount of light that reaches the areas below; In the middle area, the tiles perform as solar reflectors to aim the sun towards the center of the structure; And, in the central area underneath the structure, the bimetal, sandwiched with an insulating material, acts as a valve to allow hot air to escape. Upon entering the cavity below, the visitor can enjoy the spectacle of being inside a shiny, tessellated cave away from the sun while sitting on concrete pool benches. Added evaporative cooling (light breeze) is provided by the three fans located at the edge of the three pools of water. These fans are operated by the large turbine above, which spins as the hot air escapes through the solar chimney. No electricity is needed in this system.

Second idea was a shell, whose construction of is made of aluminium strips ‘reinforced’ by thermobimetal bows, the suares would create a shell. Empty inner part is filled by moveable pieces of thermobimetal.

When researched that heated thermobimetal stripes when putted on fabric and cooled down they cause tensed fabric, it designed the third initial idea. Pavilion consists of modules, where each module is one aluminium arch with connected thermobimetal stripes. Then the stripes are heated and a membrane is putted on a construction.

Idea - Deployable structure The system consist of thermobimetal stipes that are heated. Under influence of high temperature change shape, material held into position until it cools. As the piece cools and returns to its flattened state. it is prematurely locked into place, forming a pre-tensioned bowbeam. The result is an extremely strong and lightweight shell. The inspiration of this mechanism was the project Doris Sung Exo Structural Tower

Idea - Adaptive roof The idea was to create moveable roof component. Throught connection construction elements bimetal strips, which under influence of temperature change shape, was possible to design moveable roof system. The result is simple passive system depends on the temperature. Different part of the roof opend and close during the whole day. The mainor benefit of the system is that no compicated mechanical system is required.

Initial concept
The system depends on the range of temperature. When heated it straighten and gives a shaded space. By managing the alloys of metals, colour of the membrane and thermobimetal stripes and world orientation we make the system suitable for definied place and its conditions. The intention is to design system that will be simultaneously passive and active.
It will react with temperature – when it is hot outside the pavilion closes and gives a shading and when it is cold thermobimetal stripes go back to initial shape. To improve the principles of mechanism by means of electricity – for instance when it is raining and cold outside the pavilion will close and give people a shelter, which might be very useful during some events.
