Case Study: Gas Conversion Significantly Reduces Utility Costs and Emissions for Upper West Side Co-op


Danielle Apartment Corporation, a 79-unit cooperative located at 140 West 71st Street in Manhattan, was burning highly-polluting heating oil #4, which New York City has mandated be phased-out by 2030. To comply with the city’s order to convert to cleaner fuels, and in an effort to reduce the building’s carbon footprint, lower fuel expenses, and better control heating distribution, the board reached out to FirstService Residential for guidance on determining if these goals would be achievable by converting their boilers to natural gas.


FirstService Residential turned to its project management subsidiary, FS Project Management, and to its energy advisory subsidiary, FS Energy, to conduct a feasibility study for the project. They engaged a team of contractors, as well as the local utility, Con Edison, to develop a comprehensive analysis of the costs, timeline, process, and potential savings for the board to consider.
