HGTV is building its first "Green Home" near Hilton Head Island, S.C., for a nationwide giveaway.

The Jasper House -- a three-bedroom, two-bathroom home being built to stringent environmental standards -- is in Tradition Hilton Head, a 5,300-acre, 9,500-home development in Hardeeville, S.C.

Builders of the house are following LEED standards, which stands for Leadership in Energy and Environmental Design. Developed by the nonprofit U.S. Green Building Council, the LEED Green Building Rating System is one of the leading national benchmarks for green building.

The $850,000 home will be featured on the HGTV Green Home 2008 special at 9 p.m. March 23. The giveaway will be March 21 through May 9. In the spring, the home will open for public tours.
