Heating, Insulation and Ventilation
Heating is the single largest use of energy in New York City buildings, with nearly 80% of all large multi- family buildings heated by steam distribution systems. Updating heating, insulation, and ventilation systems in buildings can result in huge energy savings, while reducing cost and increasing comfort. Nine out of the ten projects represented that upgraded these systems were large multifamily buildings. If all owners of large multifamily buildings in New York were to make similar upgrades as the projects submitted to Celebrate NYC, they could collectively save $145 million annually.

9 College Place, Brooklyn
A Local Law 87 audit identified inefficient systems, leading to the replacement of poorly installed heat pump controls. This improved system responsiveness and substantially reduced utility costs and energy use.
This project is on Exhibit Panel #2.
56 7th Avenue, Manhattan
The introduction of thermostatic radiator valves, steam line orifice plates, and a modern boiler control system eliminated over- and under-heating problems and banging pipes, transforming the heating system and reducing costs.
This project is on Exhibit Panel #5.
340 E 34th Street, Manhattan
Through envelope upgrades, including re-cladding and window replacement, this project improved the energy efficiency, comfort, and aesthetics of a 1962 white brick residential building.
This project is on Exhibit Panel #5.
510 West 188th Street, Manhattan
A construction loan from the Community Preservation Corporation allowed 510 West 188th Street to pursue rehabilitation and efficiency upgrades, including a complete roof replacement, envelope insulation, and a boiler replacement.
This project is on Exhibit Panel #5.
1717 East 18th Street, Brooklyn
Holistic boiler, steam distribution, and control system upgrades improved heating performance and efficiency, greatly enhancing resident comfort and significantly reducing utility costs.
This project is on Exhibit Panel #6.
3950 Bronx Boulevard, Bronx
Local Law 84 benchmarking inspired this steam balancing project, which added master vents, insulation, and modern controls to improve functionality while reducing energy use and operational costs.
This project is on Exhibit Panel #6.
Cabs Houses, 270 Pulaski Street, Brooklyn
This comprehensive retrofit of an occupied, low-income multifamily building included an exterior façade insulation system that reduced heating loads and improved the building’s visual appearance.
This project is on Exhibit Panel #6.
The Brevard, 245 East 54th Street, Manhattan
Following a detailed feasibility study, NYSERDA rebates facilitated the installation of a combined-heat-andpower system.
This project is on Exhibit Panel #6.
The Charlton House, 2 Charlton Street, Manhattan
Replacing the existing water source heat pumps with air source heat pumps reduced water waste and ensured more comfortable interior temperatures in this large multifamily building.
This project is located on Exhibit Panel #6.
Park Terrace Gardens, 72 Park Terrace, Manhattan
Holistic steam system upgrades and simple air sealing measures helped this co-op complex resolve heating imbalances and save an annual average of more than $100,000.
This project is on Exhibit Panel #5.
