Radio Nacional de Espana’s New Headquarters Features a Smart Facade That Cuts Emissions by 50%

With a sophisticated passive solar design and an eye-catching facade, the Radio Nacional de Espana Headquarters by architects Ravetllat-Ribas brings sustainable building to the bustling city of Barcelona. The building's complex and rigorous façade is able to screen the sun on bright and hot days, but still allow for daylight to permeate through every room. The structure is situated in the historic industrial Poblenou neighborhood, which is currently undergoing revitalization as a new a tech district. While technology may be a big part of the Radio Nacional Headquarters, it’s the architect’s sensibility towards sustainable strategies that achieve much of the energy savings in the building, including a reduction of 50% in overall carbon emissions!
The extensive modular façade not only screens the sun from the building strategically, but it also provides interest and beauty. Between the vertical exterior screen and the glass facade of the building is a perforated metal footbridge  for maintenance. The footbridge also serves as a horizontal bris-soleil to shade the building on the south side. And thus this smart combination of horizontal and vertical shading protects the building from solar thermal heat gain, thereby reducing its need for air-conditioning.
Though the building is designed to mitigate solar thermal heat gain, the architects didn’t block out the sun completely. To reduce reliance on energy-consuming lighting, Ravetllat-Ribas designed each space so that it would be illuminated by natural light . Naturally day-lit interior spaces not only help reduce energy bills, but they also provide a more enjoyable experience for the building’s inhabitants.
Radio Nacional Headquarters is an excellent example of how smart passive solar design  can go a long way in reducing a building’s carbon emissions, while also achieving architectural interest and a pleasant user experience.
