US Rep. Peter Welch on Monday announced a $114,000 federal grant to improve the energy efficiency of the O Brien Community Center in Winooski. The funds will be used to fully insulate the community center s roof and implement other energy-saving measures. The O Brien Center spent $4,000 in heating bills last year. Once the new roof is installed, the center is expected to save 45 percent in heating costs. This grant will go a long way to improving a vital community center which provides great service to the people of Winooski, Welch said. By making the O Brien Center more energy efficient, we will help Winooski save money and do our small part to fight climate change.Welch made the announcement at the O Brien Center Monday morning alongside several Winooski residents, including Parks and Recreation Director Bob DiMasi, Mayor Mike O Brien, Acting City Manager George Cross, YMCA former board chairwoman Molly Lambert, chair of the project committee Penrose Jackson, YMCA Executive Director Mary Burns, Patricia McKitrich, Rep.
