At the baseline scenario, the EUI is 53.9
By applying the envelope method the EUI had dropped to 50.5.
The detailed adjustment is changing the wall into 14-inch ICF
By the lighting method, the EUI had dropped to 45.6.
The detailed adjustments are that: 1. Lower the lighting efficiency to 0.3 E/sf. 2. Lower the plug load efficiency to 0.6 W/sf.
After applying the PV method, the EUI had dropped dramatically to 12.3.
The detailed adjustment are: 1. Increase the panel efficiency to 20.4%. 2. Increase the payback limit to 20 years. 3. Increase the surface coverage of PV panels to 90%.
As a result, adding PV panels can be the most efficient way to help us build a more sustainable building, the comparison among methods are below:
