Power Tower - The New Corporate Head Office Sets Standards

The new corporate Energie AG Oberösterreich head office – the Power Tower – heralds a new era for the energy efficiency of large office buildings. Not only is the Power Tower a landmark in the cityscape of Linz, it also serves as the modern headquarters for a vigorously expanding infrastructure group. Moreover it is a unique pilot project that implements efficient and sustainable energy usage. The Power Tower is the first high-rise office building in the world that was built with passive-house characteristics. The new corporate headquarters do not need to be connected to any district-heating system, and the Power Tower manages without using any fossil energy for heating and cooling purposes.

The design model by Zurich-based Weber/Hofer won the international architectural competition. After the careful examination of several options, the decision to build a new head office proved to be the best resolution - both strategically and in terms of costs.

The overall integrated energy design of the Power Tower consists of three pillars:

• building shell/facade
• building technology
• generation of energy.
