Investigating the effectiveness of insulation for walls of buildings in Vietnamese climatic condition

Buildings are large heat consumers in all countries. In regions like Vietnam's climatic conditions, air temperature, and solar radiation, there is a complex relationship with the energy required for cooling in the summer and heating in the winter of residential buildings. Especially, the air temperature is always changing seasonally and affecting the living space temperature in buildings through the process of heat transfer through walls, roofs, ceilings, etc. This paper presents some common insulation materials and evaluates the effectiveness of using insulation for walls of buildings. The calculations are performed on the brick wall covered with insulating layer thickness varies in the range of from 0 cm to 10 cm. The results obtained are the basis for the design of the wall using insulation and the choice of cooling or heating equipment reasonably.
