Although the first redesign strategy is estimated to achieve the net-zero
energy target, some of the other options are also viable. Figure 7.44 shows
the results of the redesign, considering a combination of different
energy-saving scenarios. The total energy reduction is approximately 2.8
MWh (30% on the total GHP consumption).

The following tables summarize energy results of the redesign options of the
LH. Results show that the LH redesign would achieve the net-zero energy
target (see Tables 7.11 and 7.12 ).
