In Zaragoza, the DHC (District Heating and Cooling) building is a Trigeneration plant that provides heating and cooling to all new buildings in the Meander in addition to co-generating electricity for the urban network.

This is a facility that would normally be located on the outskirts of the city or in industrial areas, and which would typically adopt concealment strategies. In this case, concealment is not an option and the building cannot be buried due to the flooding of the area. Instead, the project is designed for visibility and urban quality.

Exposed concrete walls with a supporting structure 25 centimeters thick enclose the boiler room with a corrugated polycarbonate roof where, under each wave, a line of RGB LED lights is controlled individually by a lighting control system. At night, light and images on the polycarbonate panels indicate the type of energy being generated and its intensity.


The system, connected to the energy central control, translates the operation of the plant into color and moving image, which measures and expresses the energy being produced, turning the building into an indicator that depends on the weather and its users.
