The process of developing environmentally friendly and sustainable building structures is an interdisciplinary task. Only with a close teamwork of people from different building related disciplines, is it possible to face the challenge of solving the real life problems involved in an integral planning process. The construction of the ZUB is an example of what today's state of the art of technology for low energy demand and sustainable building can look like. Planned as an example of a low energy building, the new office of about 1300 m2 is attached to an existing preserved building and consists of three different main parts: one for exhibitions and events, one for offices, and an experimental part for different kinds of research in innovative building techniques and building services. A special focus was given to the realisation of a sustainable cooling concept, using a renewable energy source: the coolness of the ground underneath the building. During the first two and a half year long intense monitoring period, about 1300 points of data were recorded in the entire building, the achievements have been proven and optimisations based on the measurements have been made. Results and findings from the intense measurements and from an additional three year long measurement period have also been collected. The project offers an opportunity to obtain actual proof and quantify the achievements of a good sustainable building. In addition, it highlights today's possibilities in the field of energy conservation design.
