IKEA, an international home furnishings retailer, broke ground on its future Denver-area store in Centennial, Colorado. The 415,000-square-foot building is scheduled to open in autumn 2011 as the first of its U.S. stores to incorporate a geothermal component as part of its heating/cooling system.
The retailer is having 130 bore holes, up to 500 feet deep, drilled under what will be the parking garage. A fluid will be circulated through pipes in the bore holes by a heat pump. The pump carries up the constant underground 55-degree temperatures to cool the facility in the summer and cut heating costs in the winter.
According to the National Renewable Energy Laboratory (NREL), geothermal systems can cut electricity bills 25 percent to 50 percent. In addition, IKEA has agreed to let NREL monitor the performance of its system as part of an effort to develop a database that will contain cost and performance data for multiple geothermal projects.
