Saving Resources
In fact, Sascha Arnold planned his AZ house on Lake Ammersee not only as a centre of life for himself and his family: "We wanted to maximise sustainability in terms of construction, not only for ourselves, but also for our customers, who we wanted to show what is possible today using our house as an example," he says. Architecturally, the 200 square metre home is inspired by Kenzō Tange's buildings from the 1950s. A photovoltaic system on the guest house supplies electricity and was able to cover 45 per cent of the energy requirements in April of this year. The "flow" energy management system from Hager ensures that solar energy is distributed and utilised efficiently at Haus AZ: the complete solution makes it much easier to plan and operate properties that are as climate friendly as possible. As an all-in-one system, "flow" combines energy management, energy storage and charging station in one technological solution. "This means we save energy twice over: once in later operation – and today in terms of planning and installation costs," summarises Arnold.
The "flow app" tells the client that the system provides 2.1 kWh of power even on a rainy morning. The self-generated solar energy is used, among other things, to charge electric vehicles via the "witty solar" charging station, a phase switching system that automatically adapts to the output of the photovoltaic system. Solar power that is not currently required is stored in a 9.75 kWh battery storage unit for later use.
When it comes to sustainability, the architect and owner has already laid important foundations through the choice of materials and the design of the building. For the interior fittings, Arnold opted for tried-and-tested solutions from Hager: for sockets and switches, he chose the "Berker R.1" series, which was manufactured in warm grey at Hager's own manufactory. As energy distribution, energy management, charging infrastructure and door communication also come from the Saarland-based company, all the components in the AZ house can work together perfectly and ensure the best possible use of resources from the moment they move in. "We want to help architects to reduce complexity and build in a more climate-friendly and future-oriented way without a great deal of effort," says Stefanie Wahl, responsible for communication with architects, emphasising the aim of Hager's product range.
