The diagrams compare the features in house designs of cool climate and warm climate
Overall, due to different climatic conditions, each house design is optimized with specific features that deal with the distinct weather pattern of each zone. While the house layout in cool climatic zones is designed to retain as much heat as possible, its counterpart in warm areas contradictorily has a design that prevents heat from lingering in the building.
Regarding residential buildings in cool climate, in order to fight against the chilly weather, houses are constructed with a structure serving the purpose of heat storage. In terms of external design, the structure features a high-angled roof which is aligned with the direction of sunlight to maximize the amount of sunlight coming into the house. Under the rooftop, the rest of the building is engulfed in a layer of external insulation. This insulation layer acts as the outermost fence preventing heat from escaping the structure. Inside the house, thermal building material is employed to construct the internal wall of the structure. The utilization of thermal building material will optimize the capacity of retaining heat of the house.
Considering the house structure in warm climate, contradicting its cool climate counterpart, the design of houses in warm regions aims at heat reduction. Due to the heat-up effect of sunlight, warm climate houses incorporate reflective overhanging roof in order to create shade and fight against the blazing sun in daytime. There is also a layer of insulation under the rooftop, which prevents the heat from the sunlight seeping into the house. In addition, in the day, all windows and shut and covered to ward off sunlight so that the internal space will stay at a moderate temperature. Contradictorily, when the night falls, the windows are opened to let out the stored heat from daytime.
