Overview

Facility Strategies Group (FSG) collaborated with Park City Communities (PCC) and PBB Architects on the Connecticut Housing Finance Authority (CHFA) application for the Harborview project in Bridgeport, CT, a 13-floor building with 240 dwelling units that will be undergoing a gut rehab project modernize the building and improve energy efficiency.

The new design featured several energy efficiency upgrades, including a fuel cell for electricity production with the waste heat being captured for domestic hot water (DHW) production. Electric energy from the fuel cell will be purchased via a Power Purchase Agreement (PPA) with the fuel cell manufacturer that would own and operate the fuel cell system.

Analysis

FSG analyzed the electric and DHW loads for the building and modelled the fuel cell out to assist with the sizing the fuel cell system. Several options for the fuel cell included oversizing for the building’s electric load to be able to allocate excess energy production credits to other PCC accounts. FSG analyzed the excess power production and developed financial analyses to assist with identifying the preferred system size and whether oversizing was financially advantageous.

FSG also reviewed the terms of the proposed PPA contract and assisted the client with understanding their risks under the agreement.
