The researchers wanted to understand how an existing building in Morocco uses energy for heating and cooling. They checked the building's insulation quality by using a special camera that can "see" heat. Then they created computer models to predict how much energy the building would need based on its structure and materials. Comparing different scenarios, they found that if the building had a reinforced concrete frame, it would need more energy for cooling and heating compared to not having the frame. In some cases, the need for cooling energy was up to 48% higher with the concrete frame, and heating energy needs were up to 44% higher. This research shows that the way a building is built can affect how much energy it uses for keeping warm or cool.
