US Energy Group has released data on several high-profile buildings illustrating fuel savings from its award-winning Building Energy Management System (BEMS).
The system reduces fuel, energy and water usage and can be configured to both heat and cool a building more efficiently.
At 300 East 46th Street, ES Energy Group recorded fuel usage prior to installation of the BEMS, during the 2009-2010 heating season, was 14.03 gallons per degree day. Following installation, during the 2010-2011 heating season, it decreased to 10.93 gallons per degree day.
The BEMS reduced fuel usage by 22.10%. “Based on this data, we have ordered this controller for the rest of our portfolio,” said Angelo J. Grima, director of operations, Schneider & Schneider, Inc.
The building at 40 Worth Street in Manhattan, owned by Newmark & Co., Inc. is a 702,815 s/f commercial building utilizing fuel oil and steam.
During the 2009-2010 heating season, 40 Worth used 40.08 gallons of heating oil per degree day. After installing the BEMS, the building used 30.58 gallons of heating oil per degree day. This represents a savings of 23.7% in fuel oil, or $104,935.
Another Newmark building, 1560 Broadway is 222,493 s/f. The building uses fuel oil and steam for heating. During the 2008-2009 heating season, prior to installing the BEMS, the building used 10.05 gallons per degree day.
Following installation, the building used just 7.29 gallons per degree day. This is a reduction of 27.46%.
At 230 Fifth Avenue, also owned by Newmark & Co., Inc. installation of the BEMS resulted in savings of 17.43%.
The Winter Organization conducted diagnostics on three buildings, including 730 5th venue, after installing the BEMS, finding a savings of 18-25%, with payback in about a year.
“The lion share of our savings was earned in the overnight heating cycles that prior to installation of the BEMS were difficult to control,” said Denis Muzio, director of management for The Winter Organization.
