Q2 As a building engineer, you are required to design of building's wall to be comply with a recommended thermal transmittance value (U-value) between 2.5 to 2.6 W/m²K. The wall's construction consists of brick with plaster on both sides. Table 2 shows the material's thermal conductivity and the surface resistance of the wall. (i) Based on the information given, propose the required thickness of the wall layers to achieve the recommended requirements. (8 marks)
