Passive House swimming pools
Swimming pools are typically very energy intensive, which in turn also implies a high potential for operational energy savings. These savings can be tapped by implementing various efficiency measures during design and construction, as well as fine tuning operation once the building is in use. The Passive House appraoch provides an opportunity and pathway for combining high thermal comfort, energy efficiency and ultimately also reduced operating costs. A baseline study was carried out in 2009 to assess the energy saving potentials of applying the Passive House concept to this building typology. Two pilot projects that were built in Germany in 2011 and that were closely monitored for 2 years of operation, have provided proof of concept. A link to the corresponding research and monitoring reports (in German) is listed in the literature section below. Further projects have followed since, including leisure centres and schools with pool facilities.
Swimming pools and leisure centres vary significantly in terms of their energy consumption which is largely due to different usage patterns and available facilities (sauna, spa, water features, additional gym and sports facilities, catering services etc.). It is therefore very difficult to compare and benchmark the energy performance of different pool projects. Comparative data is limited and often misleading. The Passive House approach for swimming pools is a holistic approach, aiming for high efficiency with regard to all aspects and facilities included in the project. Standardised and generally applicable energy targets for Passive House certification are not (yet) available and are instead defined on a bespoke basis for each project.

Energy efficiency concept and measures
The following article is a summary of different publications from the early research carried out by the Passive House Intitute regarding basic principles of applying the Passive House concept for the building typology public indoor swimming pools.
Based on its research work, as well as practical experience from the first pilot projects and in-use performance monitoring, the Passive House Institute has published a comprehensive guide that outline the general concept and energy efficiency strategies for Passive House indoor swimming pools. In addition to specific
The indoor swimming pool Lippe Bad in Lünen, Germany was one of two first pilot projects to be built based on the energy efficiency concepts developed in the baseline study carried out by the Passive House Institute. In order to verify that the concept and approaches in the afore mentioned baseline study worked (proof on concept) and in order to identify further energy saving potentials, the in-use energy performance of the pool was monitored in detail during the first 1.5 years of operation. The following article from the 17th International Passive House Conference (2013), summarises the main findings from this monitoring.
The second pilot project, the Bambados in Bamberg, Germany, also opened its doors to the public in 2011. Similarly to the Lippe Bad the in-use performance was monitored in detail for the first two years of operation.

St. Sidwell's Point in Exter, UK is the first Passive House leisure centre in England. It opened in 2022 and is currently in final stages of Passive House certification.
