(b) A cubical building (10 mx 10m x 10 m) with glass window on every side of the wall is shown Figure 03 (b). The opaque wall is made by various materials with properties as in Table 03 (b, i) while the solar orientation factor is in Table 03 (b, ii). If the solar absorptivity, a of the opaque wall is 0.5 and the thermal transmittance value and shading co-efficient (SC) are 2.1 W/mK and 0.4 respectively, determine the building's Overall Themal Transfer Value (OTTV); and evaluate the compliance with the value suggested in MS1525:2014 standard.
