LEED simulations for a whole campus

Austria Campus

Extensive Building & HVAC Simulations

The Austria Campus is one of the biggest office project developments in Europe with a total floor area of 303.000 m².

Most of the energy demand is supplied with renewable energies through near-surface geothermal energy and photovoltaic on the roof. The on-site generated energy is used for heating and cooling through its own district network.

Our Team was responsible for running the thermal simulations for the five building blocks and the complex HVAC system to achieve the LEED certification.

Realisation 2015-2019

Contractor: Signa Real Estate

Architects: Boris Podrecca Architekten, HD Architekten ZT GmbH– Maurer & Partner ZT GmbH, Soyka Silber Soyka Architekten

Site area: 50.000 m², total floor area: 303.000 m²
