Energy retrofit saves thousands and improves comfort for Hunter College

Mike Kingsley PhD, PE, CPMP, LEED AP

OBG, as part of a joint venture with Dewberry under contract with DASNY (Dormitory Authority of the State of New York), recently completed a major HVAC system upgrade project that saved significant energy and improved comfort for Hunter College’s Wexler Library.

The existing air handling units at Wexler Library were beyond their useful life, adversely affecting occupant comfort and energy use. This major renovation project solved the client's comfort challenges, while delivering over 630,000 kWh (kilowatt hour) and $90,000 in annual energy savings. The project replaced existing air handling systems and terminal units with new high performance systems, including direct digital control and building automation system functions. Post-retrofit measurement and verification (M&V) was conducted to prove the energy savings as part of an energy savings guarantee.

OBG also conducted ongoing commissioning of the systems to verify longer term performance—especially focusing on comfort conditions. Hourly interval data of space conditions and system points were collected and analyzed to evaluate performance and identify and address any issues. This ongoing commissioning work served as the basis for new program offerings as a NYSERDA-Qualified Real Time Energy Management (RTEM) Service Vendor.

Find out how OBG can help you achieve ongoing energy savings while leveraging NYSERDA funding assistance.

In HVAC Renovation Measurement & Verification and Ongoing Commissioning [PDF], Mike Kingsley PhD, PE, CPMP, LEED AP, an OBG thought leader in building energy efficiency, highlights the M&V methods and results used to prove energy savings, as well as ongoing commissioning of system performance. 

The project achieved fan energy savings of more than 66%, winning the 2018 Silver Award for Energy from the American Council of Engineering Companies (ACEC) of New York.

The presentation was given during the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Twin Tiers Chapter Annual Spring Symposium and Professional Development Seminar on April 17, 2018 in Binghamton, New York.
