The study looked at ways to make tall apartment buildings more energy-efficient. They analyzed how to save energy and make people more comfortable. The researchers studied a high-rise building to see how good it was at using energy. They found that the building lost heat because of outside air coming in through windows and doors. By fixing these leaks, the building can use less energy. They also looked at how much energy is used for heating, ventilation, hot water, and electricity. This helps figure out where energy is being wasted. Overall, making these changes can help save energy and improve people's lives in the building.
