Analysis 1.1 SURROUNDINGS The pathé Schouwburgplein cinema is positioned in the North-West corner of a large square in Rotterdam, possessing a predominant role in the layout of the public space. 1.2 CURENT MATERIALS Polycabonate is used as the main material of the cladding. It does not transmit natural light due to its semi-translucent features, therefore, it also breaks the visual connection between the square and indoor environment. 1.3 LIGHT Because of the little amount of natural light coming into he foyer, there is a constant need for artificial illumination. This occurs as a result of inappropriate material choice and execution, that leads to misuse of energy. 1.4 WEAK INSULATION Also the low insulation properties of the façade cause over-heating of the interior spaces during summer and a high heat dissipation during winter.
Object The main goal of the re-design of the Pathé Cinema is to create a building that is 2030-proof. Making use of the orientation, of its façade surface and natural resources, the building will not only save energy and produce it, but also improve its relation with the surroundings The strategy is so to enclose the cinema halls in a bigger “shell” both to encrease the extension of the façade, and to slightly improve the insulation properties. 1.5 ORIENTATION The orientation of the cinema permits to make use of a huge part of the façade to produce energy. East and south sides will then host more panels to collect heat.

1.6 STRUCTURE The current building is basically composed by a group of boxes (cinema halls) partly wrapped by a light façade. The new Pathé will make use of the existing trusses in the cinema halls and extend them to the outward perimeter. Since pillars will bear more weight due to the double skin façade, they will be placed at 7.5 m distance one from each other.

MATERIALS Thermal bimetal
TO SAVE ENERGY
this ‘smart material’, developed by Prf. Doris Kim Sung, has never been used for architecture before. However, its qualities would be perfect to build a self-managing system of shading without using energy. A skin composed by scales made of this material can change its configuration, reacting to temperature, at different times of the day to prevent overheating. The key to this behavior is a curling process created by combining two different metals in one sheet.
straight at a reference temperature. Metal 1 and 2 have the same lenght
TO COLLECT ENERGY
Hotter than a reference temperature, metal 1 expands and its greater lenght puts it outside of the curve.
colder than a reference temperature metal 1 contracts and its shorter lenght puts it on the inside of the curve.
Energy collector Cor-Ten panels Since not all the surface of the façade has to be transparent to enlight the interior, opaque panels prevent heat to go inside and collect it. Especially during summer, pipes, placed right under the Cor-Ten surface, will gather heat utilizig water as medium. Water can be used immediately for radiators or to store heat underground for the cold season.
ENERGETIC SYSTEM SUMMER
WINTER
Air warmed by the sun is released to the environment to prevent over-heating.
Preheated air in the double skin facade is ducted to the heat exchanger in order to consume less energy.
Sun heats water contained in the pipes which duct it underground tobe stored.
The thermal bimetal shading system helps keeping the interior cool without using energy.

Pre-heated air HEAT EXCHANGER
Heat stored during summer is now used for the wall radiator system in the cinema halls.
