Abstract
Residential buildings remain the largest energy and water consumer, the need to increase efficiency of buildings was a contributing factor for the formulation of several green building rating systems. New York City has displayed its commitment towards achieving higher standards of energy efficiency through its Local Law 84 (Benchmarking Law). Local Law 84 (LL84) requires private buildings larger than 25,000 ft2 and public buildings over 10,000 ft2 to record and share their annual energy and water consumption data with the city. Data sharing helps building owners and facility managers to set annual performance improvement targets. However, the data collected does not clearly indicate how the environmental performance of the buildings has changed over the years. To address this gap, this research leverages the publicly available data collected through LL84 to demonstrate how the energy use intensities (EUIs), water use intensities (WUIs), and Greenhouse Gas (GHG) emissions of residential buildings has changed over seven years from 2011 till 2017. The research also compares the performance of older buildings with new buildings. The data was analyzed using both descriptive and inferential statistics to determine how adoption and implementation of sustainability laws into design and construction practices have influenced the EUI, WUI and GHG rates of residential buildings in the borough of Manhattan in NYC. This method can be used as a model by all major US cities for assessing the viability of formulating and implementing the benchmarking laws similar to NYC for improving the performance of their existing residential building stock.
