If you want to explore different types of building materials, we have summarized below the rating of building materials according to their degree of energy efficiency.
5. Reinforced concrete – Specialists prefer this building material due to its strength and durability. It is known for its high thermal conductivity of 1.7 W/mK, which suggests that buildings constructed using reinforced concrete should be covered with energy efficient materials to achieve efficient heating and maintain temperature.
4. Brick – Recently there has been a growing interest in brick houses. The brick is fireproof and moisture resistant, but it has a fairly high level of thermal conductivity – 015-0.67 W/mK. For the sake of fairness, it should be noted that this building material will require significantly fewer resources to provide a high level of energy. efficiency of buildings than in the case of reinforced concrete.
3. Claydite concrete – Although it is an excellent soundproof building material with high moisture resistance properties, it is rarely used in the construction of the load-bearing walls of multi-apartment buildings, because it does not have great durability. Instead, this building material is widely used for the construction of interior partitions or exterior walls of individual houses. Thermal conductivity is 0.19-0.27 W/mK
2. Wood – It is one of the most energy efficient materials – 0.15-0.4 W/mK It takes a maximum of 3 hours to heat a house to 220C. For comparison, it can take up to 8 hours to maintain the same temperature in a brick house. It should also be noted that wood also has the ability to regulate indoor air humidity and provide oxygen saturation. One of the disadvantages of this material is that it is not flame retardant and can break down quickly, without proper care.
1. Expanded polystyrene – is one of the most energy-efficient and affordable building materials. The energy loss is minimal – 0.025-04.4 W/mK, so it is an excellent energy-saving building material. In this respect, 15 cm of polystyrene is equivalent to 5.33 m of reinforced concrete. According to statistical data from the European Association for the Promotion of EPS in Construction, 8 out of 10 houses in Europe are built from this building material.
Note that W/mK is the unit of measurement for thermal conductivity, which is calculated by the following formula Watt/(meter*temperature).
