The H L Turner Group Inc Awarded US Patent for Its High Efficiency "E-Max Hybrid™" Solar-geothermal Heating and Cooling System Design System used in the award winning ROSE Cottage Project, a zero-net-energy home featured on

CONCORD, N.H., July 22, 2014 /PRNewswire/ -- The H L Turner Group Inc. has been awarded US Patent No. 8,733,429 for its high efficiency "E-Max Hybrid™" solar-geothermal heating and/or cooling system design.   The hybrid design can yield geothermal system performances upwards of a 7.5 effective COP (Coefficient of Performance), about twice that of conventional geothermal applications.   Actual net energy cost reductions of up to 75% can be accomplished with the E-Max Hybrid™ design, along with total net reduction in CO2 emissions of nearly 70%.  A ground loop geothermal version of the hybrid system was recently incorporated into the award winning zero- net-energy residence known as the ROSE Cottage Project, which was designed by The H L Turner Group Inc. using Bosch-Buderus heat pump and solar equipment. The project is featured on the website.

The ROSE Cottage Project was the first single family home built as part of the private educational website initiative to promote the use of the zero-net construction through web-based contact with consumers, builders, and developers, along with its free electronic newsletter  "The Zero Net".  Hybrid solar-geothermal heating and cooling systems are also applicable to commercial, industrial and institutional projects where the larger economy of scale helps to further decrease the additional cost/sf of the renewable energy features required to balance the total energy use equation.

William A. Turner, PE, President & CEO of Turner Building Science & Design, LLC, is a co-inventor of the hybrid heating and/or cooling system: "We are excited to bring our hybrid designs to the marketplace. Our next step will be to partner with a multi-national equipment manufacturer or large engineering consultant to bring the use of this technology into practice at a much larger scale, and at a much faster pace, than we can accomplish alone."

Harold Turner, Jr., PE, President & CEO of the Turner Group, commented: "After an eight year application process, we are very pleased to have successfully completed our US patent award.  This kind of energy efficiency technology is but one example of what the private sector is already accomplishing towards the greater goal of CO2 reduction, national energy independence, and enhanced national security.  The Turner Group remains committed to exploring new approaches that will allow us to do more with less in the built environment, while also contributing back to our profession and our communities."
