The collection and availability of environmental datasets are essential for making accurate choices regarding environmental management, sustainability, and public health. Research has indicated that open environmental datasets can substantially benefit research, policymakers, and decision-making processes [12]. Notwithstanding, challenges exist in enhancing the accessibility of environmental data sets, such as concerns regarding data quality, privacy, and ownership. Effective management of big data for environmental sustainability requires adopting data integration, standardization, and quality control strategies, as [PERSON] and [PERSON] [13] highlighted. Implementing environmentally sustainable practices heavily relies on data-driven decision-making, which involves systematically collecting, analyzing, and visualizing data to inform policies and interventions to foster environmental sustainability [14; 15]. Understanding the availability and accessibility of environmental data is crucial for proficient environmental governance. [PERSON]. [15; 16] conducted a study on the availability of environmental data in the United States. The study revealed that despite the abundance of environmental data sources, limited access to data remains, with certain data remaining inaccessible to the public. Furthermore, collecting indoor environmental parameters is crucial for maintaining a healthy and comfortable indoor environment. The indoor environmental parameters involve various factors such as temperature, humidity, air quality, lighting, and noise levels. The parameters above have the potential to influence indoor air quality, thereby leading to consequential negative health effects, especially for vulnerable populations such as children and elderly people. Collecting and monitoring indoor environmental parameters can aid in identifying potential sources of indoor air pollution and promote effective interventions to improve indoor air quality. Collecting indoor environmental parameters is crucial for optimizing energy efficiency and enhancing building performance. Through monitoring and controlling indoor environmental factors, facility managers and residents can enhance energy efficiency and reduce energy consumption. Modifying the temperature and lighting parameters per occupancy patterns can yield considerable conservation of energy benefits while maintaining optimal indoor comfort levels. In addition, collecting indoor environmental parameters is essential for implementing intelligent buildings and integrating the Internet of Things (IoT). Sensors and monitoring devices that rely on the Internet of Things (IoT) can gather runtime data on indoor environmental parameters and communicate this information to a central control system. Subsequently, the control system can examine the data and regulate the building systems correspondingly, aiming to enhance energy efficiency and improve indoor comfort. The implementation of this approach has the potential to mitigate energy expenses, optimize building functionality, and boost occupant satisfaction. Many academic studies have highlighted the significance of collecting indoor environmental parameters. Figure 1 shows the number of publications related to indoor environments in a 10-year range. As can be seen from the figure, the number of publications increased drastically in 2021, where the smart cities trend has been a hot topic. However, we believe that due to the lack of datasets, the number of publications has been reduced. Table 1 also shows some of the research done in the environment based on the country and the collected parameters. The collection of accurate indoor environmental parameters requires the utilization of suitable monitoring equipment and data analysis software. Sophisticated monitoring equipment, such as sensors and data loggers, can facilitate the collection of precise and up-to-date indoor environmental data.
