This 200-level seminar will discuss opportunities for integrating solar and wind energy into commercial construction projects. In this presentation, we will examine how to: 1. -Create and present a best option plan for owners or managers wishing to integrate renewable energy installations (ie Photovoltaics, Solar Thermal and Wind). The integration will include review of the renewable energy application in partnership with varied heating solutions (conventional, radiant, geothermal); 2. -Identify and calculate current local rebates and tax incentives for various renewable energy options, enabling delivery of rough costs associated with a renewable option; and 3. -Integrate various requirements for renewable in building design and planning processes. The two hour presentation will consist of Powerpoint with an encouraged Q&A exchange. 2 AIA Sustainable Design HSW/CEU will be offered for attending this seminar. Liz Argo, Director of Outreach and Media Development at Alteris Renewables Inc, will be delivering this seminar.

6. Gull’s Nest Condominiums 12 Affordable Homes Units Cape Light Compact’s “Green Affordable Homes”

7. Gull’s Nest Condominiums Built using: Energy Star and LEED guidelines Renewable Energy: Best option - PV, Wind or Solar Thermal

9. Great Wind Resource

10. Residential Scale Wind Turbine on a 60’ Monopole

11. 10 kW Residential Scale Wind Turbine on a 100’ Self Supporting Lattice Tower

12. NorthWind 100 Wind Turbine on a 120’ Tower

14. Vertical Axis Turbine Technology

21. How much does Wind cost? Does not include Annual Maintenance Variables which will affect cost: - Height & Type of tower (tilt up, lattice, monopole) - Soil conditions for tower installation - Length of run from install site to power tie-in Size - Approximate Costs - 2.5kW (in 12mph wind may provide 5,000kWh) $38,000.00 10kW (in 12mph wind may provide 15,000kWh) $80,000.00 100kW (in 12mph wind may provide 170,000kWh) Will require three phase power available $500,000.00

27. Solar Energy PV & Thermal Silent Requires no fuel Emission free Pollution free No moving parts Inexhaustible Resource

28. Household Energy Use as % of total household consumption

29. Household Energy Use as % of total household consumption

31. Solar Domestic Hot Water System How does it work? Household Hot Water Tank Hot Water to House

32. Solar Domestic Hot Water System How does it work? About 1 collector per person Household Hot Water Tank Hot Water to House

33. Main Home Tank with Solar Supplement Storage Tank feed

34. Domestic Hot Water Closed-loop vs. Drainback Systems Circulates Glycol mixture in a closed loop Circulates water (or glycol mixture) - Liquid drains into holding tank when not “called on” Disadvantage: Glycol can overheat when underutilized Disadvantage: Collectors sit up at a slight angle off the roof and concern over freezing

35. Solar Drainback Hot Water Heater Note slight tilt of collectors

36. VELUX Solar Domestic Hot Water System Flashed to roof just like a skylight Closed-loop

37. Household Energy Use as % of total household consumption

41. Evacuated Tubes Evacuated Tube units are useful for higher temperature applications such as radiant floor heating and low heat exchanger loops

42. Commercial Hot Water Systems Flat Plate design is best for SHW and process heat – lowest cost – most reliable

45. Multi-Family Housing SHW System High conversion efficiency – 40% Low maintenance Reduces annual hot water bills by 60% Economies of scale for larger commercial systems

46. No Basement Tight Quarters!
