• Walk Around the Building - Check!
• Chris Williams - Voltaic Solaire
• Dylan Latimar - Build it Green! NYC
• Max Joel - Solar One
• Questions and Answers

3. Goal of the Building
• Simplicity
• Low Operating Costs

4. Baseline Building Annual
Operating Costs

6. Solar PV

7. Best Places
• Clear Roof
• Long Term Living
• New Roof

8. Economics
• Average System Size • Energy Production ~
7,200 kWh
- 5kW
• Gross Installed Cost • Value of Production
= $1,727
- $35,000
• Incentives - $23,000 • Electric Inflation
Rates = ~3%
• Net Installed Costs -
• IRR Return Over
$12,000
20 Years = 15%

9. Riskless Investment

10. Solar Thermal

11. Best Places
• Use Expensive Fuel Source - Oil, Propane,
Electric
• High Water Use Facility
• Clear Roof

12. Solar Thermal
Economics
• Standard Family - 3 to 4 people
• Gross Installed Costs - $10,000
• Net Installed Costs - $4,500
• Energy Produced ~120 Therms
• Value of Energy Offset Energy
• Oil = $428
• Electric = $844
• IRR Over 20 Years
• Oil (5% Inflation Rate) = 10.7%
• Electric (3% Inflation Rate) = 22%
