Architects and designers are finding ways to use wind energy devices on buildings to save energy and money. They created a simple method to help architects add wind devices to buildings. By looking at the building's size, location, and wind speed, they can make the devices work better and save more money. Buildings can now have special parts like solar panels and wind turbines to make clean energy. They studied how buildings with these devices work and found ways to make them work even better. They used special tests to see how wind flows around buildings and computer programs to help.
