An Analysis of Built & Social Factors that Influence Energy Use from 2012-2017 Using LL84 Energy Disclosure Data: Buildings in NYC continue to be the largest contributor to greenhouse (GHG) emissions, accounting for 66 percent of total citywide emissions followed by transportation and waste. Over 10,500 benchmarked buildings are responsible for 30 percent of NYC’s building-related GHG emissions. Of those 10,500 buildings, residential buildings represent 48 percent of building-related GHG emissions, indicating a need for analysis of energy use and GHG emissions intensity reduction measures for residential buildings. Through our research, we seek to address what social and built variables impact the energy performance of residential buildings in NYC.
