A Maryland builder entering the metro Charleston market says its houses meld the best of “net-zero energy achievable technologies under one roof.”

As a result, homeowners should see a net benefit in much lower power bills, according to Nexus EnergyHomes.

The company is launching two of what it calls “GeoSolar communities” at The Sundial at River Birch in Summerville and Sunchaser at Bridlewood Farms in Ridgeville totaling at least 47 homes and lots. They would be Nexus EnergyHomes' first neighborhoods in the state.

“Our desire to 'make America energy independent one home at a time' has been met with great enthusiasm by local South Carolina officials, developers and Realtors,” says Ann Ashley, senior vice president of Stevensville, Md.-based Nexus EnergyHomes.

“It's encouraging that the people of South Carolina share our passion and vision, and we can plan to achieve this goal together,” she says.

Nexus EnergyHomes has scheduled a groundbreaking ceremony at River Birch off Dorchester Road on Thursday, Sept. 20. The 5-6:30 p.m. event will take place at the River Birch Clubhouse, 1054 Blockade Runner Parkway.

The company says it has designed eight neighborhoods, groups of houses or individual residences in Maryland towns and counties as well as one small development in Philadelphia, the upcoming South Carolina properties and “numerous” custom homes along the East Coast.

Its communities include North Pointe, a 55-lot development in historic Frederick, Md., and Foundry Court, five luxury-custom urban townhomes in the museum district of Philadelphia.

Nexus EnergyHomes lists a half-dozen or more awards its has won, primarily among builder and clean energy associations in the Mid-Atlantic.

The Sundial GeoSolar Community of River Birch will consist of 12 lots in the neighborhood's final phase. Homes are designed to produce as much energy as they use, saving homeowners thousands of dollars in utility bills, according to Nexus EnergyHomes. The three- to five-bedroom floor plans include the Ashley model home and the Providence and Savannah designs, ranging in size from 2,500- to 3,450-square-feet. Prices will start in the mid-$300,000s. Also being offered are five lots on the Ashley River with “high-performance” building technologies, the company says.

Sunchaser is a new section of Bridlewood Farms off S.C Highway 27 to consist of a 30-lot geosolar community with three- to five-bedroom plans, including the Edisto model home and the Middleton and Grayson designs. Homes range from 1,900- to 3,100-square-feet and are priced from the $250,000s.

Features of the geosolar community houses, Nexus EnergyHomes says, are geothermal (ground sourced) heat pumps, photovoltaic solar panels, super-insulated building shells, state-of-the-art electronic and web-based controls and monitoring systems and Energy-Star rated appliances.

The company says it has conducted testing and research with the National Association of Home Builders to develop pre-designed and custom single family houses, townhomes and duplexes with net-zero energy capabilities, health and wellness benefits and its NexusVision smart communication system.

Net-Zero design features include photovoltaic solar array, geothermal heating and cooling, energy recovery ventilation, LED and CFL lights, Energy Star appliances, windows with high-performance low-E glass and structurally insulated panels. The company claims it keeps costs comparatively low for the net-zero design features.
