  5. Geothermal Energy Solutions What is geothermal energy? How does a geothermal system work? Who is using geothermal energy? Geothermal Solutions

  6. 25°C -5°C 10°C What is geothermal energy? it’s energy created by the sun and stored in the earth The temperature underground is constant between 5°C and 10°C warmerthan the air in the winter andcoolerthan the air in the summer

  7. What is geothermal energy? Geothermal energy is captured using a: Ground Source Heat Pumps Geothermal exchange Systems Geothermal Systems

  8. What is geothermal energy? The length of the loops is determined by the amount of energy needed i.e. the size of the building and its heating and cooling requirements The building envelope (air sealing, insulation and fresh air make up) is critical to sizing the system correctly water and ethanol refrigerant (grain alcohol) circulate through the loops

  9. Who’s using geothermal energy?

  10. Who’s using geothermal energy? Commercial Geothermal Market energy is becoming single largest business expense renewable technologies now offer broader and more effective choices developers see value in marketing “green” buildings with LEED Certification (Leadership in Energy & Environmental Design) Municipalities specifying geothermal for commercial projects where electricity distribution is constrained payback range 5 - 8 years

  11. Who’s using geothermal energy? University of Ontario Institute of Technology, Oshawa Canada’s largest loop installation, 8 buildings: 2000 ton system Bellwood, Ontario Residential community: 600 ton system Challenger Motor Freight, Cambridge Head office: 160 ton system New Minus School, Nova Scotia 300 tons Kimberly, British Columbia Residential subdivision: 180 ton installation Marathon Public School,Marathon 350 tons Elliot Lake Retirement Community installed during December and January: 240 tons

  12. Who’s using geothermal energy? Guelph Hydro Electric Systems Southgate Phase II • 36,426 square foot building expansion • 145 ton geothermal system • horizontal and vertical loops provide 100% geothermal heating and air conditioning • solar water heating

  13. Who’s using geothermal energy? Guelph Hydro Electric Systems Southgate Phase II Expected Energy Savings • 566,000 kWh/year (60% reduction) • approx. $50,000 a year • Incremental Capital - $230K • less than 5 year payback • Phase I and Phase II are 107,000 square feet using over 265 tons of geothermal heating and cooling

  14. 120,000 s.f. 100% geothermal heating and cooling Geo Economics $1.9 million capital Energy supply agreement set at 80% of conventional heating / cooling 25 year contract, rates increase at inflation Energy savings over 25 year period are estimated to be 75% SpringdaleProfessional Building Brampton, Ontario, Canada

  15. Why we should use geothermal energy? It’s renewable, it’s clean

  16. Why we should use geothermal energy? What do we SAVE? • A Geothermal loop would eliminate your cooling tower. • Water consumption savings. • Energy consumption savings. • Chemical cost savings. • Release of tower chemicals to the environment eliminated.

  17. Why we should use geothermal energy?What do we SAVE? • A Geothermal loop would eliminate your boiler. • No green house gases emitted to the environment. • Natural Gas costs eliminated. • Boiler loop chemical cost eliminated. • Energy consumption savings.

  18. Main Air Systems Inc. Solutions • Company Mission - A professional energy solutions team that specializes in designing and building with options of owning and operating turn-key state of the art green energy efficient systems for commercial customers. • Target customers: commercial projects – typically 100,000 + sf)

  19. Geothermal Financial Model • A financial model that focuses on both selling commercial geothermal systems as well as a long term financing option. • The financing option has a number of benefits for the building owner including: • No capital outlay required • Approximately 20% annual energy savings realized in year 1 (grows as price of electricity and gas increase)

  20. Building envelop study New building design review Thermal conductivity testing (soil) Costing Energy saving analysis (compared to existing and conventional high efficiency HVAC replacements) Proposal Next Steps
