Abstract
Public toilets are a vital safety feature for urban operations. Most independent public toilets currently necessitate the installation of energy, water, and sewage piping networks in order to function properly, and they frequently waste a significant amount of energy and water resources during the operation and disposal of excreta. The energy-autonomous technology (EAT) of freestanding public toilets can address the energy-balancing issue of toilet operation and excreta disposal. To assess the climate adaptability of this technology, the study employed DesignBuilder building energy simulation software to model and analyze energy use. According to the data, Nanning is the greatest choice in high-irradiance and high-temperature locations, while Xining provides the most advantage in high-irradiance and low-temperature areas. Battery management may be necessary in Lhasa, Xining, and Tianjin to balance supply and demand. Higher irradiance locations reduce emissions better, and Tianjin’s more balanced summer and winter energy usage makes it an excellent location to use EAT. The independent public toilets can be configured to meet usage demands without being limited by energy or water sources with EAT. This presents a novel idea for the promotion and use of toilets in water-scarce or underdeveloped areas where access to hygienic, sanitary toilets is limited.
