The U.S. Buildings sector is responsible for about 40% of the national energy expenditures. This is mainly due to wasteful use of resources and practices lacking energy efficiency consideration. This paper discusses the role of technology prioritization in accelerating energy efficiency transformation. A tool (P-tool) is developed to rank energy efficiency measures based on cost effectiveness and national impact. This tool accounts for deployment rate under various scenarios using Bass diffusion model. It is based on publically available energy end-use data and subdivides the market into 2,510 micro-segments to avoid double counting of energy savings. Furthermore, the P-tool is equipped with a technology staging methodology that evaluates the best combination of cost effective building energy efficiency measures. The P-tool provides higher level of details compared to recent studies. Furthermore, this paper investigates the impact of emerging technologies which have not been considered in previously. Finally, the paper discusses new energy efficiency targets for different building end-uses that may result in up to 50% energy savings by 2030. The paper concludes with a discussion on how the P-tool is being used to inform decision making in an effort to maximize the impact of federal funding on building energy savings.
