Residential buildings are turning from energy consumers to prosumers using PV. The building as a system combines two or more of the following branches: energy efficiency, clever PV production, thermal energy management and electric mobility. Using a smart energy- and load management as a conductor or mastermind within the building allows controlling and optimizing power consumption according to PV production. Managing existing loads can help reduce the need for additional storage in form of batteries while optimizing self-consumption and grid-services. 2016 an existing building with PV and electric mobility was equipped with new heating technology (heat-pump), additional PV and the conductor/mastermind system and is since in operation. Production and consumption is monitored and evaluated. As of September 2017 a full heating-season as well as the intermediate seasons are measured, analysed and evaluated. First findings include: increased PV self-consumption, higher economic efficiency of the PV plant for post-FiT, individual mobility with PV (solar gas station), reduction of energy consumption for heat and general electricity with higher efficiency, lower energy costs, impact on CO2 balance of buildings (decarbonisation) as well as monitoring of power production and energy consumption for inhabitants.
