The first Plus Energy House in Ronneby, Sweden

The first Plus Energy House in Ronneby, Sweden was built in 2010. It has an ECOScience System Tank 6500i and an ECOScience Buffer Tank 6500Bt connected to highly efficient vacuum tube solar panels. In this installation there is an ECOScience PLC based control system that is connected to the KNX data bus system of the house. The system tank is connected to an air-to-water heat recuperation system. The air ventilation speed is controlled based on CO₂ concentration in the room. Additionally, there is an ECOScience prototype insulated stainless steel waste water heat recuperation tank installed underneath the garage, which recuperates 30% of the heat in the waste water from the bathtub, shower, dish washer and laundry machine. The house is open for public test living. The grand opening ceremony took place in Ronneby on the 25^th of February 2010. 360° panoramaview More information at Energibo
