Ensuring the preservation of works of art and setting new standards in terms of energy efficiency and sustainability
Kunstmuseum Ravensburg
The world's first certified museum in passive house construction, opened in Ravensburg in 2013, impresses not only with its architectural beauty, but also with pioneering solutions in ventilation and air-conditioning technology.
The ventilation has heat recovery with an efficiency of around 90 % and moisture recovery with an efficiency of 60 %.
A Resolair system was installed. The maximum air volume flow is 6,500 m3/h with a maximum fresh air proportion of 3,500 m3/h - controlled via air quality sensors.
Constant room temperatures of 22 °C and a relative humidity of 50 % are essential to preserve the works of art. The planning office Vogt + Feist overcame these challenges with an intelligent solution that not only ensures maximum energy efficiency but also protects the works of art.
The city of Ravensburg, as the tenant of the building, was in favour of the passive house construction method from the very beginning. Particularly because of the significantly lower operating costs that the city has to bear as a result.
The museum, designed by a renowned Stuttgart architectural firm, was not only built according to the strict specifications of the Passive House Directive, but also had to meet specific requirements for the protection of the exhibited works of art.
The Passive House Museum in Ravensburg presented us with a special challenge. With a minimum of windows to provide optimal lighting for the artworks, we had to find innovative solutions. The natural incidence of light, which is so important for a passive house, was compensated for by installing thermal bridges and a 24-centimetre-thick insulation between the concrete and the outer wall. This double-shell construction made of old, recycled bricks required thoughtful planning and precision.
Our technology not only exceeded the strict requirements of the Passive House Directive, but set new standards. The heating requirement of 15 kWh/m2 per year was not exceeded and we achieved impressive heat recovery rates of over 75 %. These top technical achievements made it possible to optimally protect the works of art while creating a sustainable, energy-efficient museum.
To ensure air quality and comfort in the museum, the planning office opted for Menerga's advanced ventilation and air conditioning systems. The Resolair system with highly efficient regenerative heat storage packages was chosen. This system achieves an efficiency of around 90 % and a moisture recovery of 60 %.
The integration of advanced ventilation and air conditioning technology from Menerga in the Ravensburg Passive House Museum not only sets standards in energy efficiency, but also demonstrates our commitment to innovative solutions. Our technology not only creates an ideal indoor climate for the works of art, but also establishes the museum as a showcase project for sustainable building.
In order to avoid excessive air velocities, the city of Ravensburg has opted for displacement ventilation. This avoids unnecessary dust circulation in the installation rooms and thus on the pictures.
In November, the Ravensburg Passive House Museum was awarded the special "Sustainable Building" prize by the German Sustainability Award Foundation and the German Sustainable Building Council (DGNB). This recognition acknowledges not only the architectural innovation, but also the commitment to environmentally conscious and sustainable building. The museum serves not only as an art venue, but also as a model for future sustainable building projects.
