This paper explores how to make buildings more eco-friendly by using renewable energy like solar and wind power. Buildings contribute a lot to global warming, so making them energy-efficient can help to reduce greenhouse gas emissions. The authors suggest that by combining energy-saving techniques with renewable energy sources, we can create buildings that produce as much energy as they use, or even more. Different ways to design these super-efficient buildings were discussed, taking into account factors like cost and environmental impact. Using renewable energy can play a big role in this green building movement, with methods like solar panels and heat pumps helping to cut down on traditional energy use. By carefully planning and designing buildings this way, we can make a positive impact on the environment and fight climate change.
