The technology often employed for energy-efficient buildings includes Building Management Systems (BMS) and various smart technologies. BMS integrate various building operations, such as heating, ventilation, lighting, and security, to optimize energy usage. Smart technologies may include energy-efficient appliances, IoT sensors, and automation systems that monitor conditions and make real-time adjustments to minimize energy waste. By leveraging these technologies, buildings can significantly reduce their carbon footprint, lower operational costs, and enhance occupant comfort while promoting sustainability in urban design.
