1. Simple Deep Well Geothermal only = best first payback, system variations will likely save between 40% and 60% over fuel oil. Medium Carbon footprint.

2. Adding solar supplement can reduce geothermal electrical use, payback extends a few years, higher 30 year lifetime savings. Small Carbon footprint.

3. Adding solar thermal storage and employing the TBS E-Max system can halve electrical demand over simple geothermal only, payback extends further, still higher 30 year savings. Ultra Low Carbon footprint.

4. Adding grid tie solar photo-voltaic panels = Very long payback but achieves “Net Zero” energy. Carbon neutral footprint.

NEXT GENERATION - SOLAR / GEOTHERMAL Turner Building Science & Design, LLC. has taken a new approach to geothermal heating in New England by coupling highly efficient, total enthalpy type, plate heat exchanger heat recovery ventilation systems with a new patent pending, ultra high efficiency, solar / geothermal energy source to yield a new standard in geothermal operating efficiency. An added benefit of the new configuration which improves long term maintenance savings, is the use of fewer and larger compressors which do not work nearly as hard, thereby increasing their useful life. Actual net energy cost reductions of up to 75% can be accomplished with the “E-Max” technology, along with a total net 68% reduction in CO₂ emissions. This combination of technologies can provide a significant reduction of both fossil fuel usage and electrical consumption in New England, and have the potential to contribute significantly toward making New England energy independent, as well as greenhouse gas friendly. The patent pending “E-Max” solar / geothermal concept developed by Turner Building Science & Design, LLC. incorporates 500 To 1500 foot deep borehole heat exchangers with closed loop piping which are more environmentally friendly than the large open systems being designed and installed by others.

Using our patent pending “E-Max” solar / geothermal system, our design approach provides the following principle advantages:

Closed loop geothermal, no impact on aquifers or surface drainage.

Utilizes both high and low grade solar energy.

De-couples up to 80% of energy consumption from erratic market forces.

Potentially reduces total net CO₂ emissions by 68%.

Potentially reduces overall operating energy costs by 75%.
