The comfort building is the building with wind flow or ventilation including reduce the heat from roof and wall because the building gets the sunlight almost all day. Thailand is a tropical moist climate located on the equator which is hot and humid, daytime average temperature is 30-40 degrees Celsius. The roof will be the first and the top part of the building get hot from the sun
Heat is absorbed from roofing on one side by reflection, convection which some heat will be blown out by air or wind, and some of that absorbed heat into building by conduction. The amount of heat getting through the building depends on various factors.
The factors in controlling heat:
- Roofing material – the surface gloss of steel roof can reflect the heat better than the tile roof
- Roofing color – the pale or light color can reflect the heat better than the darken color
- Roofing shape – for steel roof in the Monopitch Roof Shape with lower than 5 degrees to compare with Curved Roof Shape, the heat value will be a little bit different
- Opening or Air ventilation including KS Louvre, KS Ventflow - Roof ventilation, or window can reduce heat inside the building
- Thermal insulation is heat and noise reduction. There are available in the insulation panel from the factory and the separate insulation sheet installing at the construction site. The insulation will be low thermal conductivity to make loss of heat into the building. (Cool condition)
Roof and Thermal Insulation
Roof Insulated System can reduce heat inside the building and also do the noise reduction. According to the chart, Roof Insulated System can reduce the temperature to 31 Degrees Celsius which can reduce of a lot of heat.
From the above article, it showed that there are many factors in controlling heat, starting from the good roofing material, roof color and surface, and roof shape, so it can be heat reflection and wind convection which effect heat into the building. The installation of air ventilation and thermal insulation in addition will also help reducing the heat transmitted into the building.
