Welios
The Welios is a permanent exhibition on the subject of renewable energies and corresponds to the concept of a science center . The building is located near the city center of the Upper Austrian city of Wels , the opening took place on April 16, 2011.
The name "Welios" is made up of the city name and the sun god Helios .
Exhibition and content
The permanent exhibition covers the topics of energy efficiency , energy saving and especially renewable energies on 2,500 m² . In various indoor and outdoor areas, visitors are brought closer to the areas of water and hydropower , biomass , solar energy and wind power as well as geothermal energy in a playful way. According to the operator, the independent and playful experimentation of visitors with the approx. 150 exhibits is in the foreground.
In the special exhibition area, further subject areas are implemented in so-called hands -on exhibitions on 550 m² in a changing rhythm . There are special programs and workshops for school classes.
Buildings and Architecture
The building was designed by the architects from Linz, archinauten , and built using the lowest-energy method . The builders are the city of Wels and the state of Upper Austria, who have transferred their competencies to the Upper Austrian Science Center Wels Errichtungs-GmbH. Welios Betriebs-GmbH will run the business at its own risk.
Lowest energy construction
The Welios is the first building of this size to be built using the lowest-energy method. This was only possible through a sophisticated energy concept, the solid construction and a highly insulated outer wall structure. In order to achieve an energetic optimization, an ongoing energy balance monitoring was carried out from the beginning of the project and especially during the implementation planning .
Lighting concept
The architecture, with its visually blown-open facade, made optimal use of daylight for the building. As a positive side effect of this unusual construction, the opposing glass facades provided mutual shading of the interior. The energy-saving lighting is controlled by daylight-dependent brightness sensors.
Comfort concept
The thermal comfort and a comprehensive sense of wellbeing for visitors and employees were the focus of the technical planning from the start. On the upper floors, component-integrated climate areas were used for a pleasant radiant climate. In areas with higher loads (entrance area, catering, ...), highly efficient and quickly reactive air conditioning elements were installed behind acoustic drywall panels. In addition to the ceiling and floor activation, modern low-temperature underfloor heating was installed on the ground floor . The exhibition building, which can hold up to 1000 people, is ventilated via a sensor-controlled ventilation system with highly efficient heat recovery . As a result, the amount of air can be adjusted exactly as required. Due to the optimal temperature level of the groundwater used, all air conditioning surfaces and cooling registers in the building can be supplied with it. As a result of the efficient heat recovery, only a small amount of reheating is required through the solar district heating. This is produced by means of vacuum tube collectors on the exhibition roof about 100 m away.
Drinking water management
In order to ensure that the drinking water is used in a way that conserves resources, all sanitary facilities are supplied by a utility water system from the "Welser Heide". The 20 m² solar thermal system installed on the roof was equipped with a high-performance hygienic storage tank for hot water preparation.
Power generation
Electricity is generated via building-integrated photovoltaics in different usage variants. On the one hand, this was integrated in the glass roof of the entrance area. The special feature of this design is the geometry - none of the 25 modules are the same as the other. With a cell spacing of 40 - 50 mm, an additional 50 percent shading of the interior could be achieved. This resulted in a reduction in the cooling load. The total output of the installed polycrystalline solar cells in the glass roof of 5.1 kWp is 4500 kWh annually. On the other hand, there are the so-called "lines of force" integrated into the facade and equipped with solar cells - the architectural highlight of the building. With these ribbons spanning the building, the Science Center got its unmistakable appearance. The 109 monocrystalline cells used achieve a total output of 3.7 kWp with an annual yield of approx. 2200 kWh. Thanks to the backlighting with energy-saving LED light strips and the associated display options for the facade, the building receives the necessary presence and attention even in the dark.
history
The foundation stone of the Welios was laid in the 1990s by the Austrian Federation of Industrialists . In Upper Austria, a science center with a distinct experience should be created. The project development for the project took place in the Energyland project group, which developed the idea of a science center on the subject of renewable energies in cooperation with the city of Wels, the state of Upper Austria and partners from business and education. The Welio opened on April 16, 2011. In February 2011, construction work was interrupted by a fire.
