ART Architects designed a 4,525-square-foot Greek revival home west of Boston that achieves net-zero energy performance. The residence uses a 17-kilowatt solar array, air-source heat pump, and advanced insulation to eliminate heating and cooling costs. The house generates more energy than it consumes annually. The design integrates 19th-century aesthetics with modern building science, preserving neighborhood character while achieving ambitious environmental goals. This demonstrates that sustainability can be achieved in any architectural style.
