Not only is it green but it’s easy on the eyes. That’s what state officials are saying about a new geothermal temperature control system planned for Lincoln Tomb State Historic Site in Oak Ridge Cemetery.

Contractors are expected to begin installation later this month. By next spring, the system’s 300-foot deep pipes, filled with antifreeze liquid, will be ready for use. In the summer, the system will send heat from the building underground, where the year-round temperature is about 55 degrees, and in the winter send heat from the ground into the building.

The geothermal system will replace the current 20-year-old heating and air conditioning system, part of which is located inside a fenced area just northwest of the tomb. That visual obstruction will be removed when the new system is in place. Once the new pipes are underground, they’ll be covered with grass.

The project, funded by the 2009 capital bill and an Illinois Clean Energy Community Foundation grant, will cost about $376,000. Officials don’t know yet how much energy the new system will save.
