Energy Concept

Efficient energy management on a tight budget was central to the development of the design. Inspiration for the arcade came from nineteenth-century garden architecture and the big spaces of industrial buildings. The 10-metre wide internal boulevard acts as a buffer to the building behind. 

The facade is glazed with Thermo plus heat-insulating glass and can be adapted to seasonal changes. In the winter the lower panels are closed, but in summer they slide upwards, like large sash windows, for ventilation and access to the lake. In summer the under floor heating system is used to cool the interior, and use is made of the water that is warmed in the process. There is also an external awning to protect the floor of the arcade from overheating in summer.
The facades of the pavilions are constructed of simple wood and aluminum elements with heat-insulating glass and French windows. They incorporate ventilation panels for night cooling the concrete floor slabs which, accordingly, act as a thermal flywheel. The facades are fitted with automatically controlled external fabric blinds.


Building Energy Features:

Orientation of main facades West
Natural ventilation: App. % of gross floor naturally ventilated 90%
Night-time venilation provision Natural
Thermal transmission of building envelope 0.81W/m2K
Utilization of building mass thermal storage as part of energy strategy Concrete floor slabs
Solar control sysems External shading
Daylighting app. % of net floor area needing arifical lighting during daylight hours 5%
Energy-saving controls for artifical lighting? Instabus
Other Roof-mounted PV installation
The building's performance is controlled by its energy management system. Lighting is automatically adjusted in accordance with external light levels, and heating switches off when the ventilation panels are opened.With one of the worldwide largest rooftop solar power plants constructed, the Science Park demonstrates that the use of solar energy is also viable in metropolitan areas of the northern hemisphere. An investment of 6 Mio. DM was required for the construction of the plant which was provided by the European Union Funds, the State of Northrhine-Westphalia and RWE Energie AG. The equivalent of its electricity output covers the energy demand of 40 four-person households and will save an estimated 4.500 tons of environmentally harmful CO2 over the course of its service life. More important than the physical output of the solar power plant is – of course – the effect in terms of publicity for solar technology that was generated by this installation. As as study of the European Union showed in 1999, the Science Park owns the most prominent solar power plant in Europe. It was here that lots of visitors from abroad got the idea in mind of how to use this technology in large scale applications.
