The diagrams illustrate how houses are designed for cool and warm climates.
Overall, it is clear that house design in a cool climate focuses on retaining internal heat, while the design for a warm climate aims to reflect heat during the day and allow ventilation at night.
Regarding the house for a cool climate, the design uses thermal building materials to store heat inside the building, while insulation is added on the external walls and roof to reduce heat loss. In addition, the roof has a high-angled shape, and there is a large window positioned directly facing the sun to absorb maximum sunlight and thermal energy into the interior.
In contrast, the house design for a warm climate operates differently between daytime and night. During the day, insulation is installed externally to reflect heat, complemented by a reflective roof material and roof overhangs that provide shade. Furthermore, the windows remain closed and covered to prevent warm air from entering. At night, the windows are opened to create ventilation, which allows cooler air to pass through the house so that the stored heat can be effectively removed.
