Official applause for Lower Falls center

Local and state dignitaries officially celebrated the reopening of a more energy-efficient Lower Falls Community Center last week. Using state and city money, Newton officials spent more than $819,000 to renovate the 1950s-era building, with the improvements including a new roof, replacement windows, skylights, insulation, and a new boiler. As a result of the upgrades, the building at 525 Grove St. is expected to consume about 70 percent less energy, city officials said. While the facility has been in use for months, with the work finished in August, the grand reopening ceremony Tuesday drew area residents, aldermen, Mayor Setti Warren, state Representative Kay Khan, and state Energy and Environmental Affairs Secretary Richard Sullivan.  “We're proud of the partnerships,” Warren said. “This is a model we can use for other buildings.”
