Fig. 2.18 - Daily electrical energy consumption for the three householdsOn the other hand, at this low level of aggregation peak demands appear not to beeffected by seasonality (although a slight time shift in the evening peak demand canbe picked up between February and August), but rather to the sum of the differentappliances which are active during any specific time. Chapter 5 further explores this.2.4.4.2 3 Household building - Current efficiency vs. high efficiency electricaldemand scenariosIn order to create the demand profiles required in the high efficiency electricalscenario, Stage 3 of the transformation process was applied to the current efficiencyelectrical scenario demand profiles of the 3 households modelled in the previoussection.Figure 2.19, Figure 2.20 and Figure 2.21 show the transformed demand profiles forhousehold 3B for the same characteristic days shown in Figure 2.12, Figure 2.13 andFigure 2.14. For comparative purposes the high efficiency electrical demand profileis superimposed on the current efficiency electrical demand profile (dotted black linein the background).Appendix ‘B’ shows similar figures for the other two households.63
