Ruukki's solar thermal roof provides hot water for Earth House at Finnish Science Center

HELSINKI/FINLAND, June 27, 2013 - Ruukki Classic solar thermal roof has been installed on the roof of a prototype school building in the Science Park Galilei at Heureka. Working together with Finn Church Aid, Earth House Oy has designed a building that produces electricity without being connected to the grid.

"Ruukki Classic solar thermal roof has been designed to generate energy to heat the domestic water of a single family home, but the heat collector is also ideal for other applications, such as this prototype school building, where the aim is to be self-sufficient in energy production," explains Jouni Metsämäki, SVP, Building Components, at Ruukki.

Earth House presents its building systems for developing countries in the Science Park Galilei at Heureka, in Vantaa, Finland. Earth House buildings can be used to build entire villages, including houses and schools. The building materials can also vary depending on what is available locally. Earth House aims to provide an ecological solution, for example, for humanitarian organisations, to building in developing countries and in disaster areas after catastrophes. The materials for the prototype school building have been kindly donated.

"The building can help give the public a broad picture of renewable energy sources and also compare their output in different weather conditions. At the same time, the problems gripping the entire world are highlighted through the solutions and not just from the catastrophe aspect," explains Mikko Myllykoski, Experience Director at Heureka. "We plan to put the prototype school building to the test also in winter use. This will provide the building designers with useful experiences. Many disaster areas experience bleak, cold conditions," he adds.

Ruukki has developed a new type of product to harness solar thermal radiation, the Classic solar heat collector, which is fully integrated into the roof structure. The idea is to design single-family homes so that they use minimum energy. It is now possible to increase the ecology of buildings so that they produce some of their energy requirement by utilising solar heat.

Classic solar heat collector blends in almost invisibly with the rest of the roof structure. The heat collectors are available in sets of three sizes: four, eight and 12 square metres. The rest of the roof is ordinary steel roofing. The prototype school building in the science park at Heureka has been fitted with a four-square-metre solar heat collector, which can produce an estimated 1,400-2,200 kWh of electricity a year. In an ordinary single-family home, this is enough to heat the annual consumption of the family's domestic hot water. Ruukki has also provided the steel frame structure for the prototype building.
The prototype school building can be seen at Heureka - The Finnish Science Centre in Vantaa, where it will be officially opened on June 7th. The building's roof-integrated energy system can be seen during Heureka's opening hours. Ruukki Classic solar thermal roof will also be on show later this summer at the Housing Fair 2013 in Hyvinkää, house number 14.
