Green building techniques focus on creating structures that are environmentally responsible and resource-efficient throughout their life cycle. This includes using sustainable materials, optimizing energy efficiency, and minimizing waste. Techniques may involve the use of solar panels, rainwater harvesting, and recycled materials to reduce the building's carbon footprint. Additionally, green buildings often incorporate natural lighting and ventilation to enhance indoor air quality and reduce reliance on artificial heating and cooling. These practices not only benefit the environment but can also lead to cost savings for homeowners and businesses through lower energy bills and reduced maintenance costs.
