The headquarters for Spanish energy utility provider Endesa fuses innovative workplace design with a progressive environmental program.

The design transforms the Spanish building tradition of large, internal courtyards into a modern, climate-controlled solution for Madrid’s harsh winters. A 33,000 square foot atrium plays a central role, acting as the “lungs” of the building. Through an innovative design and operable windows the building is ventilated naturally, requiring no conventional air-conditioning.

The atrium also acts as the main circulation space, welcoming visitors and employees alike. Work spaces are arranged around the atrium and are flexible, adaptable to the company’s needs over time.
