Because of the construction of the Water Expo 2008 in Zaragoza are implanted to the apex Rivergate northern buildings to house the facilities associated with the generation and transformation of energy with a high level of technical and urban demand. In this case the building DHC (District Heating and Cooling) is a central Trigeneració which provides heating and cooling to all new buildings as well as co-generating electricity Meander pouring to the network. This is a facility that usually place the outskirts of the city or in industrial environments and in areas such as the Barcelona Forum 2004 takes concealment strategies. In this case it is chosen as hiding and can not be buried in the ground inundabilitat you choose to express the will of visibility and urban quality.
The building is solved with concrete walls, dark gray inside and outside, with supporting skin structure 25 cm thick. The boiler room has a light roof and explode resolved by corrugated polycarbonate sheets where, in each wave, place a rail RGB LEDs individually controlled by a “lighting control” that allows to generate images. This large screen for projecting images of 20 × 20 meters is completed with another coat of soil 4 feet high and 30 meters of the same characteristics.
At night when the building was closed to the public, are light and outdoor images of polycarbonate panels that tell us what kind of energy and how hard it is generating. The system, connected to the control of the power plant means the plant operation to color and moving image, which measures and expresses the energy in production, converting the building into an indicator that depends on the weather and users.
