Residential and commercial buildings account for more than half of the electricity consumption in the United States. There are numerous practical solutions to make buildings more energy efficient and sustainable. Although it is well-established that green buildings are socially, environmentally, and economically beneficial, there is still a lack of green buildings in the residential sector. The installation and upfront costs for these houses are very high. This research aims to facilitate a broader understanding of the cost benefits of energy efficient and sustainable residences. The Life cycle cost analysis (LCCA) approach and energy simulation tools have been utilized and integrated for assessing the traditional single-family residence in the United States. A comparative study has been carried out including passive and net-zero energy through energy simulation software. This analysis will benefit academic researchers and industry practitioners to analyze and evaluate challenges and opportunities in energy efficient and sustainable residences.
