Pich-Aguilera Architects | The symbol of the International Horticultural Exposition in Qingdao

Architecture IMG_0619

The proposed pavilion has to be the symbol of the International Horticultural Exposition to be held in Qingdao in 2014 and convey the meaning and values of the event itself. The flower has always been a reference in Chinese culture since ancient times and its representation a source of inspiration.

We propose a textile facade that captures a natural space inside, where the most significant plant species from different latitudes are grown. The architecture lives in nature and technology and it is treated as a model of germination; both of them have to pedagogically evoke another way to build and inhabit. The appearance refers to a flower, but the reference is a system that is located beyond the flower itself, “How to explain a flower with a flower?”

BIOCLIMATIC DESIGN

The pavilion is designed to work, as much as possible, with natural resources, tending to be a self-sufficient system. Almost all the energy that it needs will be provided by the ground and the sun. The mountain energy is captured by underground wells and is brought to the top of the flower to acclimatize the upper space. Solar panels will provide the electricity needed for lifts and lighting. Water will be collected by the pedestrian platform, accumulate in the lake a behind the pavilion and used to water the plants and improve the summer microclimate of the interior through evapotranspiration.

HIGH-TECH TEXTILE SKIN

The exterior skin is made of a technological textile tensed surface. The properties of the membrane, its red color and transparency, will provide a warm light to the inner ramp during the day and will project an intense light at night, being a visible landmark of the region.

INTERNAL MICROCLIMATE

Thanks to the combination of the inner surface made of bamboo, the presence of abundant vegetation and the use of an evapotranspiration system, the interior of the pavilion enjoys a special microclimate, interacting with each season’s weather conditions. The climate is controlled not only by the exterior skin, but also by computer controlled systems as a natural lighting control system and a water nebulizer system, which allow the best conditions for the growth of different kinds of plants on its interior. The contribution of the geothermal air coming from the ground, will help to temper the internal environment.

WATER NEBULIZER SYSTEM

This climate control system produces a fine mist by forcing water through small spray nozzles. The water droplets produced are so small that they evaporate instantly. This evaporation cools the surrounding air, lowering it by as much as 11 degrees in seconds. By increasing the humidity to 95% and lowering the temperature it is possible to create a microclimate in some areas of the building to grow plants that require special conditions. The curtains or clusters of mist are also a landscape interesting element. With an additional installation of LED light can add a dramatic effect in the evening.

GEOTHERMAL AIR THROUGH BURIED PIPES

This energy saving system provides comfortable air conditions for the inside through an energy exchange between exterior air and the ground temperature. The ground has all year long about the same temperature, and in the winter turns the air hotter and in the summer cools the air. This ground tempered air energy will be use for the exhibition hall spaces. It is an all year long saving system with no maintenance costs.

NATURAL LIGHTING SYSTEMS

Solar tubes allow sunlight to reach dark spaces, reducing artificial lighting energy needed and providing increased welfare in spaces through the presence of the dynamic exterior light.

GREEN ROOFS WITH RAIN WATER TANKS

Water will be collected by the pedestrian platform, accumulated in the lake behind the pavilion and used to water the plants and improve the summer microclimate of the interior through evapotranspiration. The water from the northern lake will be purified with special plants and pumped when required.

SOLAR CELLS AND EFFICIENT ARTIFICIAL LIGHTING

Solar cells will provide electrical energy for lamps, lifts and other electrical devices. Those high technology elements will be perfectly integrated on the platform pavement. Low energy consumption LED lamps will be installed behind the external textile skin.
