Problem Description: 
Do energy star certified buildings in NYC show energy reductions compared to those non-energy star rated buildings? Looking at the 2013 and 2014 NYC energy and water disclosure benchmark data, New York City’s buildings can be evaluated based on the star grade levels they received. Energy start buildings can help reduce energy consumption and reduce environmental impact once a building meets Environmental Protection Agency regulations. According to the Department of Energy, to earn a certification, a building must earn Energy Star score of 75 or higher whereas a score 50 or above reflect the median energy performance[1]. To see whether energy star buildings make less environmental impact, this report compared buildings with the below median and those above the median.
