Kunstmuseum Ravensburg

The facade consists of recycled bricks from a former monastery, which means that the project also focuses on reuse and sustainability in its choice of materials. Behind the simple brick shell lies a state-of-the-art passive house. The solid concrete construction with 24 cm of thermal insulation ensures an airtight envelope with minimal heat loss. The primary energy requirement is only 15 kWh/(m²·a), which is significantly below the applicable standards.

A central element of the energy concept is component activation, which contributes significantly to the climate stability and energy efficiency of the building. The ceilings and walls are activated via a heat pump with a geothermal energy source. In winter, the building is heated at low flow temperatures of 26–28 °C, and in summer it is cooled at 18–20 °C. The high storage mass of concrete and bricks compensates for temperature peaks and ensures a constant indoor climate of 21 ± 1 °C – a key requirement for museum operations. In combination with controlled ventilation and heat recovery, this creates an energy-efficient overall system that does not require conventional air conditioning.
