Echo | Technical University Delft

NetherlandsNetherlandsCompany Name: B&O Projectafbouw B.V.

Project description

Echo is the new interfaculty building for Technical University Delft, designed to meet this leading university’s need for flexible extra teaching space – now and in the future. It was established in light of the ever-increasing student numbers and the need to support different educational typologies and teaching methods. It is a sustainable building in which the wellbeing of the user is central.

This energy-generating building offers a variety of teaching rooms to cater for the diversity of teaching methods and study styles. As the most sustainable building at the TU Delft, this campus building is contributing to the university’s ambition to operate a fully sustainable campus by 2030. Echo is energy-generating, including user-oriented energy for laptops or illumination. Solar panels, insulation and heat/cold storage have been applied.

The interfaculty building offers 1.700 teaching places in seven teaching areas with capacities varying from 64 to 700 persons. Some rooms are flexible and adjustable, like the main auditorium that can be split into three separate education rooms. Echo also offers multiple pleasant areas to meet or eat.

Echo is characteristic for its special shapes and heights, which, combined with the high demands on sound insulation and fire safety, created interesting challenges for contractor B&O. They required extensive preparation and engineering to meet all the high demands and specifications with creative solutions.
