MassMutual Completes Rooftop Solar Project

Company launches renewable energy initiative with more than 600 solar panels; underscores commitment to “green” practices

(Springfield, MA) - Massachusetts Mutual Life Insurance Co. (MassMutual) announced today the completion of a $2.4 million solar construction project at its headquarters in Springfield, Mass., reaffirming its commitment to increasing earth-friendly “green” standards in its operations by reducing its environmental impact and improving sustainability.

“By installing more than 600 solar panels on the roof of our headquarters, MassMutual has made great strides at adopting earth-friendly operations, reducing our carbon footprint, and providing a sustainable and renewable source of energy for our campus,” said Roger Crandall, President and CEO, MassMutual. “We are very pleased and excited about our renewable energy initiative.”

The entire system, which includes 528 photovoltaic and 96 thermal solar panels, was installed on a 40,000 square foot parcel of MassMutual’s 9.6 acres of roof on its main campus and has a life expectancy of more than 20 years. The thermal panels will provide 50 percent of campus hot water needs while the photovoltaic system will provide 111 kilowatt hours (kwh) of electricity, enough to power 22 average Massachusetts homes annually. The panels will also cut MassMutual’s carbon emissions by 1,830 metric tons of CO2 over the life of the system.

The overall project took nearly five months to complete. Various state-of-the-art technologies were used in the project including a white polyvinylchloride (PVC) roof, which is a proven tool for reducing roof temperatures and internal air conditioning expenses, while also increasing the operating efficiency of the solar panels.

“Not only will this solar system reduce our operating costs and fuel consumption, it will also provide an opportunity for other area businesses and organizations to learn about renewable energy technology,” said Mr. Crandall.

The project also provided the opportunity to recycle and donate materials that would otherwise go unused. More than 2,000 boards of foam insulation removed from the company’s roof were donated to the ReStore, a non-profit home improvement center that sells leftover or unwanted building materials from construction projects at a discounted price. In addition, more than 250 tons of stone ballast were removed from MassMutual’s roof prior to the start of the project and will be reused around the company’s main campus for drainage and landscaping.
