USPS on way to conquering green targets
USPS is now more than two thirds of the way to achieving its goal to reduce energy use by 30% by 2015. One year after opening its first green roof in Manhattan, USPS said it is exceeding its energy savings targets.
The green roof, atop the Morgan mail processing facility, covers 109,000 square feet, or nearly 2.5 acres. During construction, approximately 90% of the original roof was recycled and reused on the new roof.
The green roof is the largest in New York City, and is one of the Postal Service’s largest environmental projects to date. It will last 50 years, twice as long as the roof it replaced, and is part of the Postal Service’s greener facilities strategy.
“A year ago, the Postal Service projected the green roof would help the Morgan facility save $30,000 in annual energy expenses,” said Tom Samra, vice president, Facilities. “We’re pleased to have surpassed that goal, saving more than $1m since the implementation of the green roof and other energy-saving measures at Morgan.”
The Postal Service also projected the green roof would help reduce polluted storm water runoff 75% in summer and 40% in winter. According to Samra, the Morgan facility is on track to meet those goals, and is taking steps to monitor additional building performance measures including water quality, bio-diversity and urban heat island effect.
Samra attributes the accelerated rate of savings to a 40% per month reduction in energy use and an average decrease in energy expenses of 15% since the green roof’s opening. The Morgan facility replaced 1600 windows, deployed other energy-saving enhancements, and is pursuing Leadership in Energy and Environmental Design (LEED) and High Performance and Sustainable Building (HPSB) certifications.
Current LEED-certified postal facilities include Post Offices in Denver, CO, and Southampton, NY; and mail processing centers in Greenville, SC, and Troy, MI. Across its 33,000 postal-owned facilities, the Postal Service is making great strides reducing energy use as it implements energy-saving projects across its inventory – impacting up to a total of 287m square feet.
In 2009, the Postal Service implemented its Enterprise Energy Management System (EEMS) which allows the Postal Service to monitor, manage and measure facility energy data and performance. Matched with a ‘culture of conservation’ among postal employees, EEMS has helped validate the Postal Service’s decrease in energy use by 10.8 trillion British thermal units (Btus) since 2005, and avoid more than $400m in energy costs since 2007.
“We’re working greener every day,” said Sam Pulcrano, vice president, Sustainability. “Our total energy use is down and to date, the Postal Service has reduced facility energy intensity by more than 21% based on a 2003 baseline, well ahead of the federal goal of 12%.”
