The study looked at how the design of the outer walls of tall apartment buildings affects how much energy is used inside. They focused on Turkey's tallest residential building between 2010 and 2017. By using a computer program called DesignBuilder, they found that having a special design with a double-layered air corridor in the walls can make residents feel more comfortable and reduce energy use by 30%. This design cuts down on the energy needed for heating and cooling compared to regular buildings, showing that smart wall design can help save energy and make people living in tall buildings feel cozy.
