11 SUSTAINABILITY STUDY: HVAC HEAT PUMP SOURCE: EARTH-COUPLED COP:

12 SUSTAINABILITY STUDY: HVAC DIRECT SOLAR ENERGY SOLAR COLLECTOR PANEL FLAT-PLATE COLLECTOR - Residential and Commercial - Temperature below 200 F EVACUATED-TUBE COLLECTOR - Temperature higher than 200 F

13 APPROVED SOLUTION: SOLAR GROUND SOURCE GAS BOILER DHW HEATING and COOLING SOLAR COLLECTOR PANELS HEAT PUMP - GROUND SOURCE

14 APPROVED SOLUTION: SOLAR GROUND SOURCE SOLAR COLLECTOR PANELS GEOTHERMAL FIELD

15 Smart Soutions SOLAR COLLECTOR PANELS SOLAR COLLECTOR PANELS - 42 Collector Panels - 1,700 sqft Collector Area

16 Energy Flow Diagram APPROVED SOLUTION: SOLAR GROUND SOURCE SOLAR COLLECTOR PANELS

17 Smart Soutions SOLAR COLLECTOR PANELS - 42 Collector Panels - 1,700 sqft Collector Area GEOTHERMAL FIELD GEOTHERMAL FIELD - 62 Wells ft deep

18 GEOTHERMAL FIELD - 62 Wells ft deep APPROVED SOLUTION: SOLAR GROUND SOURCE RAUGEO TM ; DOUBLE U-BEND U - Less boreholes - If one UBEND is compromised, the entire borehole is not lost - Reduces borehole resistivity - No fused joints in the borehole field

19 GEOTHERMAL FIELD - 62 Wells ft deep APPROVED SOLUTION: SOLAR GROUND SOURCE PIPE PEX PIPE PEX-a - PEX-a pipe has superior material properties vs. HDPE - resistance to crack growth - high impact load / notch resistance

20 APPROVED SOLUTION: SOLAR GROUND SOURCE

21 Energy Flow Diagram / HEATING CONVENTIONAL SOLAR GROUND SOURCE

22 Energy Flow COMPARISON INPUT CONVENTIONAL SOLAR GROUND SOURCE SAVINGS GAS 78% 12% -66% ELECTRICITY 22% 26% +4%

23 Energy Flow SUMMARY CONVENTIONAL SOLUTION: - needs 2.7 x more NON-RENEWABLE ENERGY SOLAR GROUND SOURCE - PAYBACK ~8 years (LIFETIME from WELL FIELD is 50+ years) - Life cycle COST SAVINGS $430,000 over 20 years (in PV 2008 Dollars) - Reduction of GREENHOUSE GASES 50,000 kg CO 2 per year
