Warm air rises, so ceiling insulation is designed to have a higher r-value and the insulation is often installed between the ceiling joists or rafters. A properly insulated and ventilated roof is called a cold roof. A warm roof is a roof that is not ventilated, [9] where the insulation is placed in line with the roof pitch. [10]
In a stratified building, temperature differentials of up to 1.5°C per vertical foot is common, and the higher a building's ceiling, the more extreme this temperature differential can be. [2] In extreme cases, temperature differentials of 10°C have been found over a height of 1 meter.
The building in Australia applies insulation in roofs, ceilings, external walls, and various components of the building (such as Veranda roofs in the hot climate, Bulkhead, Floors). [23] Bulkheads (wall section between ceilings which are in different heights) should have the same insulated level as the ceilings since they suffer the same ...
Cool roofs offer both immediate and long-term savings in building energy costs. Inherently cool roofs, coated roofs and planted or green roofs can: Reduce building heat-gain, as a white or reflective roof typically increases only 5–14 °C (9–25 °F) above ambient temperature during the day; Enhance the life expectancy of both the roof ...
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
Thatch is also a natural insulator, and air pockets within straw thatch insulate a building in both warm and cold weather. A thatched roof ensures that a building is cool in summer and warm in winter. Thatch also has very good resistance to wind damage when applied correctly. Thatching materials range from plains grasses to waterproof leaves ...

The chimney has to be higher than the roof level, and has to be constructed on the wall facing the direction of the Sun. Absorption of heat from the Sun can be increased by using a glazed surface on the side facing the Sun. Heat absorbing material can be used on the opposing side. The size of the heat-absorbing surface is more important than ...
