CA Immo lets 21,500 sqm of Silbermöwe office building to Bosch   

Robert Bosch AG is letting the entire floor space of CA Immo's Silbermöwe office building on the Lände 3 site for a period of at least 10 years, CA Immo said in a press release on Friday. The volume of 21,500 sqm makes this the largest new letting on the Vienna office market for 2012 so far. According to Bruno Ettenauer, Chief Executive Officer of CA Immo, “Attracting a high quality tenant such as Bosch amounts to another major boost for the Lände 3 site. We leased around 30,000 sqm to Österreichische Post AG at the end of 2010, and this new agreement represents the biggest new letting for this year in the urban district Lände 3 so far. Overall, the project has shown how an intelligent and properly thought out programme of refurbishment can create modern premises from existing buildings. Inner city sites are upgraded and revitalised as a result.”

The building is a ten-storey high-rise that will be enclosed by a seven-level U-shaped structure; in addition to full renovation of the interior, the facades of both structures were completely refurbished. Various construction measures have cut the energy requirement of the fully renovated building by 50-60 % and reduced carbon emissions by 280 tons per year. A solar power installation on the roof, for example, will supply most of the power required by the building equipment; meanwhile an energy-efficient aluminium and glass facade and a chilled ceiling system combined with radiators will maximise energy efficiency.
