“…In summary, the above studies suggest that the fundamental requirement of IGB is to reduce the load on the environment while also providing a safe, healthy and comfortable living space. It is environmentally friendly and achieves the harmonious coexistence and long-term progression of humans, architecture and the environment [89,90]. Its concept is in-line with the needs of smart city construction.…”

At present, the integration of green building, the intelligent building industry and high-quality development are facing a series of new opportunities and challenges. This review aims to analyze the digital development of smart green buildings to make it easier to create contiguous ecological development areas in green ecological cities. It sorts out the main contents of Intelligent Green Buildings (IGB) and summarizes the application and role of Digital Twins (DTs) in intelligent buildings. Firstly, the basic connotations and development direction of IGB are deeply discussed, and the current realization and applications of IGB are analyzed. Then, the advantages of DTs are further investigated in the context of IGB for DT smart cities. Finally, the development trends and challenges of IGB are analyzed. After a review and research, it is found that the realization and application of IGB have been implemented, but the application of DTs remains not quite integrated into the design of IGB. Therefore, a forward-looking design is required when designing the IGBs, such as prioritizing sustainable development, people’s livelihoods and green structures. At the same time, an IGB can only show its significance after the basic process of building the application layer is performed correctly. Therefore, this review contributes to the proper integration of IGB and urban development strategies, which are crucial to encouraging the long-term development of cities, thus providing a theoretical basis and practical experience for promoting the development of smart cities.

“…Swimming facilities are complex and energy-demanding facilities with strict requirements on the indoor environment for both air and water, as compared to other sport centers. The high energy demand is to maintain the indoor conditions and water quality while providing energy for the various systems [7]. The energy use is around seven times higher compared to other public buildings, and the energy performance of swimming facilities is relatively less studied compared to other building types [5].…”

Positive energy districts (PED) are neighborhoods with a net positive energy balance with the main goal to create sustainable districts that contribute to the energy transition. The three pillars energy efficiency, renewable energy, and energy flexibility forms the foundation of PEDs, and ‘Quality of life’ is one of the key principles. Indoor swimming facilities for recreation and sports, also called aquatic centers or swimming halls, are important for healthy lifestyles. They are highly energy-demanding facilities due to the large volumes and strict heating- and ventilation requirements to ensure the health of staff, visitors, and bathers. The large energy consumption indicates good potential to reduce their energy use. One possibility might be to include aquatic centers in PEDs: the district could support the facility with locally produced renewable energy. There are also studies that investigates innovative solutions regarding aquatic centers that might have potential to increase resilience and flexibility in the district. However, one important aspect in studies on energy use in aquatic centers that is often neglected is the presence of disinfection by-products (DBP), which are found in the air and water of chlorinated swimming pools. Several DBPs can lead to health issues, such as asthma, eye irritation, and even cancer. There are often conflicting goals in studies on swimming halls. The connection between DBP and energy is currently missing, and it could lead to projects compromising health over energy savings. Based on a literature review, this study highlights the research gap between DBPs and energy use in swimming facilities. A suggestion is also presented to integrate swimming halls into PEDs with the aim of increasing possibilities for a healthy lifestyle, supporting the aquatic center’s energy demand with renewable energy, and exploring new solutions for flexibility and resilience in the district.

“…As a result, due to these constructive and functional characteristics, very high temperatures are reached in the interior space, which do not comply with thermal comfort standards for heated swimming pools [33,34] and cause very high energy costs for cooling. These circumstances are common in many heated pools, and appropriate solutions are urgently needed [35][36][37]. This work analyses the benefits in the energy performance of retrofitting these pools by applying natural cross-ventilation and increased solar control of the enclosure.…”

This paper studies the energy behavior of several public heated swimming pools with semi-transparent covers located in southeastern Spain with high consumption of their air-conditioning installations. The scientific novelty of the work is to determine the influence of solar radiation on the energy performance of this type of building and to demonstrate that the use of passive systems such as natural ventilation and solar control enhance the energy efficiency in glazed heated swimming pools in a warm semi-arid climate. The methodology used consisted of on-site measurements of current hygrometric behaviour and a study of alternative solutions by simulation of virtual models with improved hygrothermal conditions. In the on-site measurements, thermographic images were used to analyse the thermal envelope and hot-wire probe measurements to determine the temperature distribution and air velocity inside the pool enclosure. For the study of alternative solutions, simulations were carried out, including an analysis of incident solar radiation and different natural ventilation and solar control solutions. The results obtained showed that the current hygrothermal behaviour of the interior spaces does not comply with the regulations on the thermal quality of the indoor environment. The results show that the proposed natural ventilation and solar control solutions substantially improved the hygrothermal properties and energy savings of the pools analysed. This work offers an alternative solution that avoids the implementation of costly air conditioning systems and the energy consumption of installations, promoting more sustainable renovations that contribute to improving the indoor comfort of users with interventions that are compatible with existing buildings.
