Huge Energy Savings in 55 Wall Street Building
Gross Floor Area
Number of Units
55 Wall Street, constructed in 1836-1841 is a 9 stories 188,278 sq.ft. restaurant, commercial, retail and residential building located in downtown, New York. The building is owned by Cipriani Club Residence and operated and managed by FS Residential runs 24/7. This residential portion was converted in 2005. Before those floors were used as hotel. In 1998 it was completely rebuilt as The Regent Wall Street Hotel. The residential portion includes 107 units that are mostly occupied. The exterior of this building was designated a New York City Landmark in 1965. The building was named a National Historic Landmark in 1978. 55 Wall Street took advantage of New York State Energy Research and Development Authority’s (NYSERDA’s) FlexTech Program, and with assistance from Geo-Tech and NY Building Systems Consultant Inc (NYBSC), developed new strategies to reduce energy and operating costs and improve energy efficiency.
An energy audit ASHRAE level II and Retro-Commissioning (RCx) study was conducted, co-funded by NYSERDA, focusing on potential opportunities for energy savings and operational improvements at 55 Wall Street. The Study recommended that upgrade the lighting to LED, replace the existing both old life expired absorption chillers to high efficiency absorption hot water and gas fired chillers, high expensive ConEd steam to gas fired condensing and steam boilers, Variable Frequency Drives (VFD) on thirteen (13) AC and pumps motors, upgrade the outdated existing Building Management System (BMS), two passengers Elevators modernization, and install Cogeneration. Also sixteen RCx measures including pipe insulation, control valve fix, replace steam traps, fix or replace the malfunction sensors and fix water side economizer control were recommended to improve existing equipment performance and reduce energy cost.
Results and Incentives
55 Wall Street will receive $19,962.50 in funding through the NYSERDA FlexTech Program for this energy study. NYBSC’s energy efficiency audit and commissioning evaluation identified a total of Twenty Three (23) energy conservation measures (ECMs) and RCx findings with an annualized cost savings $967,153 and a capital cost of $7,369,894, resulting in a return on investment of 7.62 years. Possible incentives are more than $1.6 million for capital construction.
The New York City Energy Efficiency Corporation (NYCEEC) is a non-profit energy finance company who is interested the landing the entire capital cost without the building owners paid no upfront costs and will be repaying through energy savings. This report and funding opportunity that the board has initiated is timely and strategic due to the buildings cooling system i.e. the chiller recently breaking down and no longer being able to supply adequate air conditioning to the residences and event space.
