“…To this end, there are energy simulation models that aim to improve the energy efficiency of swimming pools [28,[82][83][84]. Specifically, energy stress drives efficient optimization studies through the prediction of energy consumption and savings, as well as the improvement of the energy cycle of swimming pools [85][86][87][88][89][90]. Regarding the use of renewable energy, such as solar energy, for heating swimming pools, there are studies that seek to achieve an energy balance between all the alternatives [35,36,43,78,85,[91][92][93][94].…”

The aim of this research is to propose a more sustainable swimming pool, in terms of water and energy, in the Costa Brava area. The methodology is focused on the creation of a descriptive water and energy model for swimming pools and their monitoring, to propose the transition to a more sustainable swimming pool, in the context of climate change. The research is characterized by an exploratory, descriptive, and simulation approach to adapt swimming pools to the new requirements. Two significant impacts are highlighted from the perspective of water and energy stress—the carbon footprint, related to environmental impact and climate change, and the new business models of the sector, for a more sustainable tourism, with more sustainable pools. In terms of water balance, evaporation is an important variable and there are technical solutions on the market to control it, such as the use of covers. Furthermore, the modeling and simulation carried out helps to calculate the variable as a tool for improvement. For energy balance, in outdoor pools, pumping is an important variable and there are technologies, such as speed variation, that make it possible to reduce this. Furthermore, it should be noted that this research represents an important tool for the improvement of sustainability and operability for the various stakeholders, especially owners and governments, to face climate change, which is becoming increasingly critical for many regions.

For a country with a tropical climate, such as Indonesia, heat pump technologies are usually necessary in high-altitude regions, where the temperatures tend to be cooler, such as a pool heater for an artificial hot spring swimming pool. A vapor compression heat pump’s optimal performance relies on its working fluid’s characteristics. This paper aimed to assess the performance and compare the time required to heat a hot spring pool using heat pumps with two different refrigerants: R32 and R134a. A thermodynamic modeling approach was employed to determine the better refrigerant choice between R32 and R134a for the heat pump, aside from other important factors that are considered when selecting the refrigerant, such as safety and environmental impacts. Comparing the results of R134a and R32 refrigerants, R134a has a higher GWP value than R32, indicating that R32 is more environmentally friendly. Regarding safety, R134a has low toxicity and flammability, while R32 exhibits low toxicity and mild flammability. Thus, R134a is considered safer than R32. Furthermore, the COP value of R134a was found to be higher than that of R32, indicating that R134a offers greater efficiency for the heat pump compared to R32.

The aim of this research is to critically evaluate the environmental implications of public pools in Costa Brava hotels, with a focus on their impact in terms of energy, water, and carbon footprint. The methodology employed hinges on the characterization of the stock of pools installed in the hotels of the region. Following this characterization, calculations were undertaken regarding water and energy consumption, in addition to the computation of the equivalent carbon footprint for the entirety of the pools combined. The findings of the study reveal an annual energy consumption of 1,850.2 MWh/year and an annual water evaporation consumption of 50,105 m3/year. As a result, the carbon footprint corresponding to these consumptions is 481.8 tCO2 eq./year. Identified areas of improvement within the facilities encompassed the modernization of equipment towards more contemporary models with higher efficiencies, the adoption of holistic management approaches for pools, and the utilization of emerging modelling trends to enhance facility efficiency. Conclusions drawn from the research suggest that enhancing the sustainability of pools within the Costa Brava hospitality sector holds significant societal relevance, especially when considering the heightened water stress in Mediterranean climate zones during the peak tourist season. Improving the energy efficiency of these facilities not only contributes to environmental sustainability, but also cuts operational costs, allowing establishments to have more room to channel more resources towards their main hospitality tasks. Highlights Tourism is vital in global, Spanish, Catalan GDP and an environmental impact key. Costa Brava hotel pools use 1,850 MWh/year, 50,105 m3 water/year, emit 482 tCO2/year. Modern equipment, management, and modelling trends enhance pool sustainability. Efficient pools cut costs, aid environment, free resources for hospitality. Tourism's future relies on holistic sustainability; efforts and policies are vital.
