- Make a luxury shopping center and a center for sustainable business
- Create an open constructed urban cool, shaded and lit naturally
- Perform a set of commercial and office buildings that stay cool in summer without air conditioning, despite the high temperatures reached in summer in Seville.
2. Architectural Solution
To an ambitious urban renewal project in the city of Seville has chosen a privileged suburban area for the large-scale architectural 4, signed by 4 international studies in architecture: Arata Isozaki, Jean Nouvel, Norman Foster and ... ... .... The goal is classic: make a great performance architecture with a strong visual impression, in order to encourage private investment in an area.
Well, on a plot bordering the area of operation mentioned a local developer wants to make a large shopping and business center, following the same guidelines as public investment. That is, create a building model with a high architectural quality, which can act as social demand, which can become a symbol of Seville and serve as a reference to the architecture of the future.
The architectural ensemble on the ground floor includes a collection of small luxury shops (reserved for large international companies), along with cafes, restaurants and meeting facilities (including a large interior plaza deck). The different floors houses a small set of smart offices, equipped with the latest technology. Finally, the plant houses covering a diverse set of gardens, restaurants and cafes.
The aim of the architectural ensemble is to offer an attractive environment that provides comfort to its occupants, visitors or potential customers. Thus, given that the biggest environmental problem of Seville are the high temperatures of summer (along with its high humidity) the first priority is to make a complex of buildings that provide shade and cool. This was taken as a formal reference to the forest: provides light, natural ventilation and protection.
On the other hand, given that it is a mall of luxury goods and high-level offices, has been chosen as inspiration formal diamond. The brightness, transparency, subtle changes in tone and color, and triangular and diamond are both formal architectural complex invariants.
So arguably the formal reference is to realize it would be "a forest of diamonds."
The mall has 4-based composite triangular building volumes interconnected with each other, so that the center forms a large square, shaded deck, where there are cafes and meeting centers. The internal streets are arranged together so that between the maximum intensity of natural lighting to all rooms of the buildings, but without being heated by solar radiation. As a result, the whole is shaded, cool and bright. An ideal environment that encourages walking, social interaction and human welfare.
3. Bioclimatic Characteristics
1.1. Heat Generation Systems
The building is heated by itself, in two ways: 1. Avoiding cool: Due to its high thermal insulation, and having large glass surfaces just to the south. 2. Due to its careful and special bioclimatic design, and perfect NS orientation, the building is heated by the greenhouse effect and direct sunlight, and remains hot for a long time, due to its high thermal inertia. 3. Architectural geothermal system to heat the air passing through a series of underground tunnels located in the basement of the building.
Winter in Seville is very smooth, and the mechanisms described are enough to ensure the welfare of the occupants of the building and public areas inside.
1.2. Fresh Generation Systems
The building cools itself in three ways: 1. Avoiding heat, providing most of the glass surface just to the south and east, providing sun protection for the direct and indirect solar radiation (a type of protection different for each of the holes with different orientation), and providing isolation appropriate. The central square is completely shaded, so it stays fresh air bag on a permanent basis throughout the summer. 2. Cooling through a cooling system architecture of air through underground galleries. On the other hand, due to high thermal inertia of the building, the accumulated fresh overnight stays for nearly all the next day. 3. Evacuating the hot air outside the building, through the upper windows of each floor and through the solar chimney.
3. Storage systems (heat or cool)
The heat generated during the day in winter accumulates on the floor slab and the concrete load-bearing walls, keeping the building warm during the night. Similarly, generated during the cool summer night up in the floor slab and the load-bearing walls, keeping the building cool during the day. The roof garden high thermal inertia, reinforces this process.
4. Transfer systems (heat or cool).
The heat generated by natural radiation emissions and is distributed in the form of hot air throughout the building through the main square and the inner courtyards of the building. Similarly, the heat stored in the load-bearing walls is transmitted to the radiation side rooms.
On the other hand, the cool air generated in the underground galleries of the building is spread through the courtyards, and through a set of grids spread over the floors. This air flow cools every room of the building.
5. Natural ventilation
The ventilation of the building is continuously and naturally through the very walls of enclosures, allowing adequate ventilation without energy loss. This type of ventilation is possible because all materials are breathable (ceramic, natural insulation, concrete panels, wood-cement panels, eco-friendly paints).
4. Most important innovations
Infinite life cycle
All components of the shopping center "La Milla de Oro" are designed to be mounted in dry base screws, nails and pressure. This can be easily recovered from the building to be repaired, reused or returned. Thus, the building can last indefinitely, with very low power consumption.
Portability. On separate pieces
All items in the shopping center "La Milla de Oro" are designed so they can be assembled and disassembled easily and indefinitely. For this reason, these elements can be transported anywhere, to be easily mounted (or dismounted) as many times as necessary.
All building components have been individually designed, and performed at the factory.
The building has very low power consumption due to its exceptional design. On the other hand, the building itself generates all the energy you need.
