Echo: TU Delft’s Energy-Positive Interfaculty Teaching Building by UNStudio

Echo, designed by UNStudio in collaboration with Arup and BBN, is an innovative, energy-generating interfaculty teaching building at TU Delft, Netherlands. Completed in 2022, this 8,844 m² facility exemplifies sustainable architecture and flexible learning environments, aligning with TU Delft's goal of a fully sustainable campus by 2030.

Sustainable Design and Energy Efficiency

Echo is TU Delft’s most sustainable building, generating more energy than it consumes. Equipped with 1,200 solar panels, smart installations, robust insulation, and a heat and cold storage system, it supplies energy for daily operations, including electricity for laptops, lighting, and catering. Approximately 90% of the building's furniture is reused, emphasizing circular design principles. 

Flexible and Adaptive Learning Spaces

The building houses seven teaching rooms with adaptable layouts to support diverse educational methods. The largest lecture hall accommodates 700 people and can be divided into three separate rooms within 15 minutes. Over 300 study spaces are available for group work and self-study, catering to around 1,700 students. 

Health and Wellbeing Focus

Echo's design promotes user wellbeing through ample natural daylight, reducing the need for artificial lighting and creating a connection with the surrounding campus and nature. A plenum floor system ensures clean air by pumping fresh air from the floor upwards, avoiding circulation around the room.

Architectural Features and Materials

The building features bamboo ribs extending along the ceiling and central staircase, creating a warm and inviting interior. Deep horizontal aluminum awnings and climbing plants on the façade filter daylight and prevent overheating. Structural elements like steel trusses and hollow-core slabs are designed for disassembly and reuse, supporting future adaptability. 

Integration with Campus and Community

Echo serves as a public connector within the campus, with its transparent ground floor acting as a covered public square. Two sculptural volumes—a large lecture hall and a debate space—guide the flow of people across this area, enhancing interaction and collaboration among students and faculty. Echo stands as a benchmark for sustainable and flexible educational architecture, embodying TU Delft's commitment to innovation, sustainability, and interdisciplinary collaboration.
