The article explores ways to create super-efficient buildings that use as much energy as they generate - these are called net zero energy buildings. Buildings consume a lot of energy, about 40%, so making them more energy-efficient is crucial. The study aims to show how to design and optimize buildings to achieve this goal. By using renewable energy sources, these buildings can produce all the energy they need. The research focuses on modeling, designing, and optimizing these energy-efficient buildings, providing various strategies to achieve net zero energy status.
