After more than 40 years of operation in Friedrich-Hillegeist-Straße in Vienna, Austria’s second district, the central and regional Viennese offices of the Austrian Pension Fund and the Centre for Outpatient Rehabilitation are undergoing extensive renovation due to signs of aging, such as leaking ceilings or poor thermal insulation. The technical services will be brought up to date and the building will be given an insulation retrofit, with particular attention paid to establishing an ecologically sustainable energy supply.
PVA decided not to demolish the building and construct a new one, but to build on the existing structures as much as possible. The existing structural frame will therefore remain completely intact and, apart from repair work, no new steel or concrete will be used. Building on existing structures, in the form of reconstruction, conversion and refurbishment, is an important contribution to a sustainable future.
A particular challenge will be the new envelope of the building consisting of an aluminum-glass façade being realized by STRABAG subsidiary Metallica. All materials were carefully selected with a focus on their subsequent recyclability.
Bringing the existing building up to the latest standard also requires the modernization of the building services equipment, as well as the renovation of the roof and all rooftop structures.
Following the complete gutting of the building, the full spectrum of building services equipment will be brought up to date. This includes utilities lines, the power supply, as well as the heating and cooling systems. A green roof with shaded areas, together with a special landscaping concept, will help to positively influence the urban microclimate, enhance the common areas and provide additional protection against overheating in summer.
Completion is scheduled for 2027.
