Building materials in the efficient case are as follows (IES VE 2013):
- Precast concrete walls finished with fiber-cement cladding, U-Value 0.1519 W/m2k
- Triple Glazing with argon air gap, U-Value 1.4554 W/m2k
- Precast concrete Roof system, U-Value 0.1404 W/m2k
- Insulated ground Floor, U-Value1.3479 W/m2k

Figure 21: Cooling peak loads calculations for the building in both cases (IES VE 2013)
Readings here show a reduction in the total rooms’ sensible load for 34.67%, making a good
amount of energy saving in case of changing the materials to make the best insulation.
