The Best Bang for your Buck modifications list in this project is based off House type 1 at 90o  orientation in the NatHERS software HERO. The existing base house was modeled and then the cooling priorities were added iteratively to the base model and the impacts on the heating and cooling load documented. This list was then ordered from biggest impact on cooling load to least impact on cooling load. From the change in KWh, a standard figure for the supply of electricity  was equated to give cost savings benefits. 

This project sets up the structure, where moving forward this would not be a manual process, but a developed database would produce the correct modifications list from the survey information.
