A ground-source heat pump will be required in every unit.
Construction has started on an 1,800-home community in Louisville, Ky., that the developer says will be the largest in the U.S. to equip every dwelling with a geothermal heating and cooling system.
The system will cost $18,000 per home in Louisville’s Norton Commons community. Homeowners could be eligible for tax credits of up to 30% on the price of the geothermal systems.
The systems negate the need for outdoor air conditioning units, which the developer says will reduce noise and free up yard space. They can save a homeowner up to 70% on heating and cooling bills.
