Jury evaluation
"This compact structure which houses the diverse usages typical of a modern leisure pool facility has more than 13,000 m² of NFA and represents an important contribution to energy-efficient construction for a type of building that is normally very energy-intensive. One of the challenges is to apply the passive-house standard to a leisure baths facility. Systematic efforts were made to reduce energy losses without compromising the functional features required, including details such as the flexible covers for overflow gutters and the outdoor facilities. Alongside well-designed heat recovery, a CHP plant is also at the heart of favourable energy provision."

Project characterisation
Building concept
The indoor pool building is planned as a leisure bath facility with a sports area to be used by schools and clubs, and large sauna facilities.
This new building sets itself apart from all other public baths in Germany with its energy-saving passive-house design. This is achieved thanks to the high-standard building envelope and the highly efficient building services equipment which is advantageous in terms of primary energy.
The overall structure of the newly built baths is intended to showcase them as an independent construction situated beside the existing outdoor baths.
The changing rooms, administration area, gastronomy facilities and the health spa area are housed on two storeys. The other areas – mainly consisting of swimming pool areas – occupy a space which is the height of two storeys.
A special feature is the warm outdoor pool on the roof terrace.
Energy concept
All ventilation systems with the exception of fume extraction in the gastronomy facilities are fitted with heat recovery that has a heat recovery efficiency of over 70%. Contrary to the standard generally in place elsewhere, only motors of efficiency grade 1 will be used as drive motors for the fans in ventilation equipment here. The high-temperature air from the saunas will be fed through the ventilation system in order to recover waste heat.
