Efficient use of energy and light for administration buildings: the new Energie AG corporate headquarters, with large-scale facade photovoltaics, energy-optimised heating and air-conditioning, intelligent energy management and innovative lighting from Siteco.
In Linz, the Upper Austrian power authority Energie AG eminently demonstrates the innovative use of its very own product, electricity, with the implementation of complex technology. As a result the world's first office tower has been constructed with a passive energy character. The so-called Power Tower is exemplary for the sparing, cost-effective use of all important building resources: thermal and electric energy, water, air and light.
The new, 19-storey administration building has Austria's largest façade photovoltaics system with a capacity of 42,000 kWh. Heating for drinking and service water is carried out without use of fossil energy sources via heat pumps. Special blinds installed in the window areas ensure very good cooling and ventilation even during the warm months of the year. A similarly energy-optimised and ergonomically efficient lighting system ensures outstanding lighting conditions, with daylight-dependent lighting control according to requirements and in excess of 3,300 Siteco luminaires.
The Siteco systems have been implemented for underground parking, outdoor lighting, the executive storeys and elsewhere. As well as a host of tried-and-tested luminaires such as square recessed luminaires, recessed light channels and rail systems, all of which feature energy-saving lamps and ballasts, the office workstations are illuminated with around 1,500 Novaluna S suspended luminaires.
What is special with these luminaires is not only that they were awarded the coveted "Lighting Design Award 2007" for their transparent, floating appearance, but that the Novaluna S is equipped with the patented ELDACON® light control system. Here the light is directed via highly precise microprismatic structures without glare and with a high level of uniformity onto the working plane. With especially high light output ratios of up to 97%, the luminaires with microprismatic technology are highly efficient in terms of energy.
