Energy-efficient design focuses on creating buildings and structures that minimize energy consumption. By utilizing advanced technologies and sustainable practices, such designs reduce the overall environmental impact. Strategies like proper insulation, high-performance windows, and efficient lighting systems help conserve energy. Additionally, renewable energy sources such as solar panels and wind turbines can be integrated into the design to generate clean energy. This approach not only reduces electricity bills but also contributes to a greener future. With energy-efficient design, buildings become more comfortable, with optimal temperature and ventilation. It is a cost-effective and responsible way to address the global energy crisis and create a sustainable future for generations to come.
