Post am Rochus is a large multifunctional building (47300 m² gross floor area) combining office and retail space. It was designed to the Passive House Standard and was completed in 2017 for the Österreichische Post AG. A 5000 m² of retail space is located at the ground floor, first floor and lower ground floor of the building, while the upper floors house the Austrian Post headquarter offices. The building has a complex energy supply system. The project received a number of 1st Prize awards.

The aim of the building owner was to obtain a modern comfortable building with very high standards regarding sustainability and energy efficiency, not only in the operational phase but also during the execution phase and commissioning. Therefore, the goal was to shorten the commissioning phase by a very detailed study and optimization of control strategies of the HVAC systems along with the involved planning, construction, and operational project team. Within the project the building was scientifically monitored and the following technologies in the HVAC system were used:
The heating energy for concrete core activation and fan coils is supplied by the local district heating grid. Service hot water is prepared decentralised by electric heaters.
