Consider a home that uses the equivalent of 16,000 kWh per year for the following energy loads.

Domestic hot water: 3,500 kWh

Refrigeration: 1,300 kWh

Lighting: 1,500 kWh

Heating: 4,800 kWh

Cooling: 2,400 kWh

Make this house a net zero home.

to make this house net zero home

the percentage increase of each load=(16000-(3500+1300+1500+4800+2400))/(3500+1300+1500+4800+2400)*100=18.52

the domestic hot water load increased to =3500+0.1852*3500=4148.148 KWh

the refrigeration load increased to =1300+0.1852*1300=1540.76 KWh

the lighting load increased to =1500+0.1852*1500=1777.8 KWh

the heating load increased to =4800+0.1852*4800=5688.96 KWh

the cooling load increased to =2400+0.1852*2400=2844.48 KWh
