Have you heard about America's largest totally geothermal neighborhood in South West Kennewick, Wa?
SouthCliffe is a 400+ lot subdivision located in Kennewick’s Southridge area. Over 10 years of planning with City officials and private landowners has gone into this project, and its timing corresponds with significant other developments in Southridge.
The developers of SouthCliffe, are adding a geothermal “grid” to each lot to provide homeowners with significant energy savings. SouthCliffe’s geothermal grid will use the ground’s nearly constant temperature, in conjunction with a ground source heat pump, to heat the house in the winter and cool it in the summer. The systems also provide the majority of hot water heating for the house. While this technology dates back several decades, lower cost ultra-efficient heat pumps are making this green technology mainstream.
Depending upon climate and soil conditions, houses with geothermal heat pump systems can expect energy savings of between 50 – 70%. Kennewick, with its cool winters and hot summers, along with highly favorable soil for geothermal conductivity, is ideally suited to this technology. When complete, the subdivision will have a thermal energy capacity of over 5.5 megawatts, or the equivalent of 3.5 wind turbines as seen in neighboring Nine Canyon Wind Farm. Savings in CO2 emissions are likewise significant; upon completion, the subdivision will result in a net reduction of approximately 10,300 metric tons of annual CO2 emissions.
This is such an exciting time for Southwest Kennewick as it is rapidly growing. The new Kennewick General Hospital is nearing completion. The new 25 acre sports complex which also has the new Carousel of Dreams. New restaurants, and commercial business are quickly populating the landscape of Southwest Kennewick.
