The 'Plus-Energie-Bürohochhaus' (Plus-Energy Office High-Rise Building) is the world‘s first office tower that can claim to feed more energy into the power grid than is required to operate AND use the building. All that in the heart of a large modern city!

Besides redefining the term ‚energy efficiency‘, the integral building concept demonstrates one thing in particular: that plus-energy office buildings are not only technically possible, but are also, above all, economically feasible concepts for the future of working on and in buildings.

The 'Plus-Energie-Bürohochhaus' is an unique research and construction project implemented by TU Wien in cooperation with the Federal Ministry of Science, Research and Economy (BMWFW) and the Federal Real Estate Company (BIG).

Unique example of interdisciplinary networking

It is more than just the refurbishment of an existing university building. The research project arose from several interdisciplinary projects within the TU's research focus point Energy and Environment - from the scientific planning to the implementation.

The new findings from the research project have set the standard for upcoming projects and construction activities for TU Wien and are already being applied for all 4.500 employees (e.g. through more efficient computers, shut-down of technical equipment overnight, etc.)
