Financial viability and environmental aspects in the selection of energy sources for sanitary hot water (SHW) and heated swimming pools

Abstract

Sustainability and energy efficiency are topics of great interest, especially in the sports facilities management sector due to the high energy costs. One of the MOST Relevant costs is derived from the consumption of domestic hot water (DHW) and swimming pool. The objective of This work is to study new ways to manage and reduce costs through the These valuation of the use of traditional and renewable energy sources and the Necessary investment to Contribute to the promotion of a more sustainable vision of business management. Four alternative energy installations (Natural Gas, Biomass, Solar Thermal Combined With Natural Gas or Biomass) are Proposed, it is verified Which is more suitable in terms of financial viability and one of them is selected. For This purpose, we start from a hypothetical companycase and a 20-year forecast of the energy consumption, the costs and initial investment of each alternative is made; viability analysis are performed With the Net Present Value (NPV) and the results are Obtained Compared. The Conclusion Is That The most Appropriate solution, from a financial point of view, for sports centers similar to the company-case and With the Considered Circumstances, is the installation of Biomass, an option That, in Addition, can be Considered respectful With the environment.
