Fully modernised prefabricated building uses solar power with an innovative storage system

Partial dismantling of entire rows of prefabricated buildings, demolition of individual building sections, reduction of the number of storeys, revitalisation of the remaining buildings, and the creation of attractive, modern living space – the construction project in Aschersleben was ambitious from the outset. The same could be said of the energy concept, which aimed for a high level of energy autonomy and energy standards that the federal government doesn’t envisage achieving until 2045. Luckily, the structural fabric was in good enough condition that it didn’t require a complete teardown – and modernisation work could begin. The developer undertook extensive insulation work, and fitted all suitable roofs and façades with photovoltaic installations. 114 kilowatt peak capacity were installed on the roofs in addition to modules with 71 kilowatt peak capacity on all façades except the north sides. The modern
apartments are heated by current-operated infrared heating, and hot water is supplied by self-sufficient boilers that make use of surplus solar power. In the future, four charging points will feed the solar power to electric vehicles – both private vehicles and a planned car-sharing project. A key component of the energy concept is the high-performance battery storage systems from TESVOLT, which ensure that the power supply works even when the sun isn’t shining.
