SST Solar

The new building with a total usable area of 1,500 m² was erected in steel and reinforced concrete construction with industrially prefabricated building elements. For the company, as a solar collector manufacturer, it was a matter of course to generate as much solar energy as possible on the building itself. 192 m² of solar thermal collectors on the southwest facade and 93 m² on the southeast facade cover up to 90% of the demand for space heating and hot water. If the solar system still does not generate enough heat, an additional wood boiler with 60 kW output can be put into operation. The heating heat is distributed in the building via two separate heating circuits. The first heating circuit consists of underfloor heating in the office area. A thermal concrete core activation system in the floor of the production hall forms the second heating circuit. The concrete core, which measures around 1,200 m² and is 25 centimeters thick, serves both as floor heating and as long-term storage for the heat generated. If the flow temperature of the solar collectors is rather low, at 25°C for example, the heat is fed directly into the concrete core. In this way, even low temperatures with diffuse solar radiation can be used for heating. Ventilation takes place naturally via openable window sashes or mechanically in the interior rooms.
