Following is an outline that highlights some of the key features of Keystone Development’s Green Building Program. Simply put, building Green, is building better. Green building practices focus on construction techniques and materials that create homes that are more energy efficient, are healthier and more comfortable to live in and help to protect the Earth’s environment. All homes are built to National Energy Star standards. In addition, Keystone Development incorporates many elements of the National Association of Home Builders’ Green Home Building Guidelines in the design and construction of their homes. Keystone Development is actively involved in establishing a standardized Green Building Program in the State of Massachusetts that will allow homes to be certified as meeting a stringent level of Green construction criteria.
