2. Use Energy Modeling for the Most Cost-Effective Zero Energy Home
- The design should then be run through energy modeling software to ensure that the zero energy goal can be achieved with this design in a highly cost-effective manner. Based on the results of the energy modeling, the design may need to be modified to reach the net zero energy goal.
- It is most effective to conduct energy modeling on different sets of energy-saving features during the design phase in order to determine the most cost effective mix of energy saving features that you are considering and to determine the smallest solar PV system necessary to achieve net zero energy for your design.
