Owners of older homes love the fact that they can live in living, vibrant, often historic, reminders of the past. They may not know that, with a little effort, they can bring those homes into the “green†present. Now, there is good news for those owners: The Neighborhood Association of the Back Bay (NABB) is sponsoring a special forum, offering tips and answering questions about how older homes can make the transformation to green energy conservation. The event will take place November 8, 2012 from 5 to 8 PM in the Orientation Room of the Boston Public Library’s main branch on Boylston Street in the Back Bay. Chris Skelly, director of local government programs for the Massachusetts Historical Commission, Rebecca Harris, field officer of the National Trust for Historic Preservation, and Sally Zimmerman, manager of historic preservation services for Historic New England, will provide guidelines and information about how older or historic houses can be turned green without losing their historic character. Some areas that will be covered are: how to add alternative energy systems, the value of retaining and upgrading wood windows, and ways to properly insulate an historic house. The event is free and open to the public. To reserve a place for “Greening the Older Home,†contact the Neighborhood Association of the Back Bay at 617-247-3961 or info@nabbonline.com.
