Sustainability Challenge Produces Savings

THE initial results have been published from the pilot energy efficiency projects as part of Sustainable Stamford’s Corporate Sustainability Challenge, in the City of Stamford, Connecticut, U.S.A.

The city is the first municipality to take part in the Challenge, launched by Sustainable Stamford, the city’s volunteer environmental task force, and the Southern Connecticut chapter of the Building Owners and Managers Association.

Over the past year, three commercial properties, as a part of the Challenge, analysed energy and water use in their facilities, developed strategies for improvements and implemented policies to meet their individual needs and budgets.

Amongst the projects was First Stamford Place, a three-building, 810,000-square-foot multi-tenanted office complex, owned by Malkin Properties.

Malkin Properties Gerrit Blauvelt, Head of Property Operations, said: “The work we are doing within our suburban portfolio replicates the groundbreaking energy efficiency retrofit program underway at the Empire State Building, a property supervised by Malkin Properties’ affiliate Malkin Holdings. Our goal was to create a package of energy efficiency measures that not only save energy and reduces water usage, but create healthier work environments and reduced operating costs, without compromise.”

As part of the Sustainability Challenge, the projects completed at First Stamford Place include the replacement of low-efficiency electric motors; the installation of variable frequency drives (VFDs) on the property’s chiller plants; the installation of occupancy sensors in all new tenant spaces; the replacement of lighting within the complex’s common areas, mechanical rooms, and garages, and the installation of water saving technologies.

By implementing these energy efficiency measures, Malkin Properties anticipates saving up to 15 percent on energy costs.

Albert B. Ashforth, Inc. revealed what they had achieved at its 74,000-square-foot office facility. To reduce energy use in the building, they installed a new high-efficiency cooling tower and an automated temperature control system. The construction of the building’s new tenant space included energy-efficient lighting operated by motion sensors and LED lights in all of the stairwells.

Greenwich Hospital, which has a 30,000-square-foot location in Stamford, also published their results.

Tom Lazzaro, Greenwich Hospital Director, Facilities Management, said: “In keeping with patient wellness, Greenwich Hospital has fully embraced the opportunity to make the building as sustainable as possible, likening sustainability to the overall long-term health of the planet.”

A committee-driven approach helped the Hospital team implement a number of changes at the facility, including several energy reduction and conservation strategies. The building is currently undergoing a lighting retrofit and HVAC system upgrade, which is expected to reduce energy consumption by about 110,000 kilowatt hours per year. These initiatives are subsidised by funding from the local utility company and will reduce electricity cost by over $15,000 a year and significantly reduce the building’s carbon footprint.

“The Corporate Challenge pilot has been a great success,” says Kristine D’Elisa, Director of the Corporate Sustainability Challenge for Sustainable Stamford. “We are thrilled to extend the Challenge to all [commercial] building owners and managers throughout Stamford this fall. From building owners, to tenants, to the local community, everyone benefits from the changes inspired by the Challenge.”
