摘要
Improvement of living standards and increased demand for consumer goods have as consequence the increase of energy and water consumption. At the same time, increasing awareness of the respective environmental impact has prompted the European Union (E.U.) to issue a list of Directives for the Member States that promote conservation of natural resources. Moreover, this environment-friendly attitude may alleviate the impact of the economic crisis, since energy and water savings result in saving money. In the present paper, some ways toimprove sustainability of swimming pools through reducing energy and water consumption, are analyzed and compared.An open municipal swimming pool in Thessaloniki, Greece, is used as case study. Research is focused on heating energy, where more savings can be achieved. Especially, installation of solar thermal collectors, geothermal heat pumps, or photovoltaic panels and construction of a light roof are analyzed. Moreover, some recommendations are made, concerning the general improvement of a swimming pool and its surroundings. The goal is to reduce the operation expensesof the pool and, if possible, to increase the income, so that it can be economically viable throughout the year. Finally, several suggestions are evaluated by means of the RETScreen software, in order to find out which investments are reasonable. For the evaluation a Cost – Benefit Analysis has been carried out, using the Net Present Value criterion, the Internal Rate of Return criterion and the Benefit – Cost ratio. Finally, a SWOT analysis is performed and a policy is suggested, which should be followed by the administration of the swimming pool.
