Content Description

Plus-Energy-Office of the Vienna University of Technology

Currently under refurbishment, the so called "Chemiehochhaus" of the Vienna University of Technology will accommodate 300 employees on 8.000m² gross floor area in autumn 2014. Due to the application of the highest standards in energy efficiency to the design of the building envelope and in the selection of the electrical equipment, along with on-site electricity generation with Austria's largest building-integrated photovoltaic system of 300kW peak capacity, the building will become a net energy producer - a Plus-Energy-Office. Thus, the 800kWh/m²a primary energy demand before renovation will be reduced to less than 100kWh/m²a, which will be fully covered by the PV system. The extremely low heating energy demand will be covered by a heat pump and district heating, while night ventilation will guarantee thermal comfort in summer. Be the first to learn more about this innovative building in the first public site visit!


The first passive office tower worldwide has been shaping the Viennese skyline since 2012 on the banks of Danube canal. Functionality, efficient resource management as well as modern, appealing architecture interact in an appealing and harmonic way. The ecological basic concept of the new office tower was to lower the demand of energy on the one hand and to benefit from the local resources in an optimal way on the other. The decisive factor for achieving the Passive House standard was the radically increased efficiency of the facade, the building component connections, the mechanical systems - and even the coffee machines. The office tower is 78 meters high and has 21 floors that offer 20 000 m² office space. Furthermore, the Raiffeisen-Tower was awarded the Austrian klima:aktiv Gold-standard with the absolute maximum of 1.000 points.
