Octagon Park Apartments CHP Demonstration(ST11185-1)

Octagon, L.P.


Octagon is a 500 unit apartment and mixed-use building, located on Roosevelt Island, which was originally built in 1841 as the New York City Pauper Lunatic Asylum. The site is a combination of certified historic rehabilitation and new construction that has been occupied in its current use since 2006. During construction/renovation, the site participated in a number of NYSERDA programs, which has resulted in it being 35% more energy efficient than New York State code. Octagon has received a LEED Silver rating. The site also claims to have the largest array of rooftop solar panels on any residential building in New York State.

Project Description

A UTC Power Pure Cell System Model 400 fuel cell will be installed. The Pure Cell unit is a pre-engineered, pre-packaged system consisting of the fuel cell, heat recovery sub-system, and associated support equipment and controls. Thermal energy recovered from the CHP system will be used for space heating and domestic hot water production.


The system will be configured to provide electric power to the site during periods of grid outage. Priority loads include emergency lighting, fire-detection and fire-suppression systems, as well as carbon monoxide detectors. The system is expected to reduce grid electric consumption by over 3,300 MWhr/yr and supply over 8,200 MMBtu/yr in space heating and domestic hot water. This project will permit a planned expansion without the need for a utility upgrade. The site has already implemented a number of energy efficiency measures. This will be the first-known installation of a fuel cell in a multifamily building. The proposed CHP system is appropriately sized for the site.
