The given diagrams outline contrasting approaches and thermal regulation from different residential architecture drafts tailored to hot and cold climates.
Overall, it is apparent that the primary distinction lies in their different thermal objectives. Dwellings in cold regions are designed to retain heat. Meanwhile, others, in hot climates, focus on heat absorption and promoting dissipation
In cold areas, residential houses are equipped with various systems to optimize solar energy gain and minimize heat loss. First of all, steeply angled roofs are equipped to increase exposure to sunlight, leading to the effective storage of heat. Beneath roofs, thermal building materials are used to retain heat. Furthermore, homes are designed to have thick wall insulation to prevent heat dissipation during the day and night. Additionally, windows are strategically positioned directly to the sun so as to capture natural light and its warmth before it sets.
Conversely, external insulation and heat reflection can often be seen in houses located in hot regions to reduce temperature. During daylight hours, dwellings’ roofs are covered with reflective materials and thin insulation walls to reduce heat absorption. In comparison, a contrast structure (compared to house structures in cold weather) is that these houses might have roof overhangs or extended eaves to provide more shade. Notably, windows are closed in the daytime to block the UV light from the sun; however, these can be opened at night to facilitate cross-ventilation and allow heat to escape as well.
