Figure 16: Electrical Load Profile and Inside and Outside House Temperatures after the<br />
house was a subject of a sustainable “ makeover” where all major electrical appliances<br />
were replaced by sustainable alternatives. Source [11].<br />
From Figure 16 is evident that the electrical energy consumption for this particular house<br />
was reduced and the electricity is used for refrigeration, lighting and entertaining purposes<br />
only.<br />
Another study [10] investigated the Electrical energy consumption in a typical low-cost<br />
house and the results are shown in Table 5.<br />
