+ | The possibility of reliably predicting the energy demand of a building during the planning stage is a basic prerequisite for achieving a high level of energy efficiency as this allows optimisation of individual components and of the overall building concept. The energy flows in an indoor swimming pool are extremely complex and difficult to comprehend on account of the many interactions and control systems. The multi-zone PHPP mentioned previously was developed for this reason. This tool was during the planning stage for the specific project requirements and is still being further developed. | ||

- | Apart from pool water heating, the other major applications (space heating, hot water generation and electricity) were already correctly represented in the energy balance during the planning phase. With adjusted boundary conditions, correlation of the measured data with the calculations is excellent (keeping in mind unavoidable uncertainties), | ||

- | More accurate correlation of the calculation with the measured data is not to be expected solely \\ on account of discontinuous operation and remaining uncertainties relating to some of the \\ assumptions. The magnitudes are correctly calculated. | ||

- | Heating the required hot water accounts for the biggest share of the overall final energy consumption (pool water and hot water for other uses), followed by the total for the electrical applications. Some of the findings obtained so far from the data evaluation of the Lippe swimming pool and their effect on the energy balance calculation are described below. \\ | ||
