Jakarta is located in the tropics, with high temperatures and humidity throughout the year and concentrated rainfall during the rainy season. The poor air circulation and the significant temperature difference between indoors and outdoors lead to prominent energy consumption issues. The ERV ventilation system, with its core advantages of energy recovery and efficient air exchange, has high adaptability in various scenarios in the region. Firstly, in high-density residential buildings, whether it is the upscale apartments in South Jakarta, the compact residences in the central area, or the newly built residential communities in places like Ngaglik, these buildings are generally highly sealed to cope with frequent rainfall, but they are prone to causing dampness in bathrooms, the accumulation of kitchen fumes, and hotness in bedrooms. The ERV system can continuously exchange indoor and outdoor air while recovering the cooling capacity of the air conditioner, significantly reducing the energy consumption for dehumidification and cooling, and is particularly suitable for small-sized and fully-finished residences, neither occupying excessive space nor improving indoor air quality, which meets the dual needs of local residents for comfortable living and energy conservation. Secondly, in public buildings such as schools and hospitals, the classrooms and libraries of schools in Jakarta are densely populated with students, which can lead to an increase in carbon dioxide concentration and affect learning efficiency. The wards and treatment rooms of hospitals have strict requirements for air cleanliness and stability of temperature and humidity. The ERV system can reduce energy loss while ensuring continuous ventilation, avoid drastic fluctuations in indoor temperature, and filter out pollutants in the air, creating a healthy environment for teachers, students, and patients. The public nature of these places makes them urgently require cost control for operation, and the energy-saving feature of ERV can significantly reduce long-term operating expenses. Thirdly, in industrial buildings such as food processing and electronic manufacturing, Jakarta is the core of Indonesian industry. These buildings need to strictly control indoor temperature and humidity to ensure product quality. For example, food processing plants need to prevent raw materials from getting damp and deteriorating, and electronic workshops need to avoid the accumulation of heat generated by equipment operation. The ERV system can recover energy during ventilation, maintain a stable indoor temperature and humidity environment, reduce air conditioning load, and remove production odors and dust, helping enterprises meet local production hygiene standards and improving product qualification rates. There are also hotels and commercial complexes in Jakarta, which is an important tourism and business hub in Southeast Asia. Hotel guest rooms, shopping malls, and dining areas have high personnel mobility. The ERV system can quickly remove odors from guest rooms and kitchen fumes, reduce air conditioning energy consumption through energy recovery, and improve guest experience. For commercial places that pursue high-quality services and cost optimization, it is an important configuration to enhance competitiveness, especially suitable for high-end hotels and large shopping malls located in central business districts and tourist hotspots. Finally, in office buildings and multinational enterprise workplaces in the central business district and other modern office areas, these areas have dense office equipment and long-term personnel stays, with high requirements for indoor air quality and environmental stability. The ERV system can effectively replace the polluted air generated by equipment operation and personnel activities, recover energy to save office energy consumption, meet the needs of enterprises for green office, and provide a comfortable environment for employees, improving work efficiency, and adapting to modern office scenarios in the central business district, Setiabudi and other areas of Jakarta.
