Highly energy-efficient indoor swimming pools - Passive house concept for indoor swimming pools: Measurements and guide-lines for planning

In recent years, the first Passive House indoor swimming pools have been intensively investigated. Already in these pilot projects, it was possible to reduce heating and electricity consumption to a considerable extent. On the basis of this experience, further potential can be exploited in future projects. It is crucial to use the possibilities of the interplay of architecture, technology and operation in order to reduce energy costs in the long-term use of the building. In the current research project investigations (theoretical and based on measured data) were carried out on evaporation rates, energy balance of the pool water, pollutant concentrations and ventilation control. The gained knowledge and planning values make it easier to identify and optimise the essential influencing factors for the planning, construction and operation of energy-efficient indoor swimming pools. Already with the design (zoning, ventilation zones, proportion of glazing, pipe lengths, height differences etc.) the course can be set for a cost-effective and at the same time highly energy-efficient pool. The published guideline with planning information and the checklists for commissioning and optimisation of operation [2] offer assistance for further indoor swimming pools (new construction and renovation).
