  1. 1. Certified Energy Manager LEED AP BD+C davidgibson1@gmail.com Powered by Sunshine: Net-Zero Energy Homes as a step toward 100% Renewable Energy David Gibson 1 UNR Renewable Energy Minor October 18, 2016
  2. 2. 2 UNR Renewable Energy Minor April 6, 2016
  3. 3. Blower Door 6 • Used to measure air leakage before and after sealing • Precisely calibrated • For every cubic foot pulled out through the BD, one cubic foot is leaking in • Helps identify air leak locations and magnitude
  4. 4. Economic Analysis To determine which improvements should be made, we compare the upfront cost to the savings over time: • Simple Payback – How long does it take the measure to pay for itself? Calculation: upfront cost / annual savings • Return on Investment (ROI) – Can be compared to other investments (stocks, bonds, mutual funds, etc). Calculation: annual savings / upfront cost UNR Renewable Energy Minor October 18, 2016
  5. 5. Actual Energy and Cost Savings System Before Improvements Projected Costs Actual Costs Actual Savings Percent Savings Heating $4,022 $2,686 $850 $3,172 79% Cooling $0 $0 $0 $0 --- Water Heating $549 $549 $385 $164 30% Lights and Appliances $1,138 $968 $950 $188 17% Service Charges $115 $115 $115 $0 0% Total $5,824 $4,318 $2,300 $3,524 61%
  6. 6. Economic Analysis (LED Lights) Would you give me $100 today, if I offered to pay you $10/month for the next ten years? UNR Renewable Energy Minor October 18, 2016
  7. 7. Economic Analysis (LED Lights) Would you give me $100 today, if I offered to pay you $10/month for the next ten years? $120/year x 10 = $1,200 Payback: $100/$120 = 0.833 years (10 months) ROI: $120/$100 = 120% UNR Renewable Energy Minor October 18, 2016
  8. 8. Low-Flow Showerhead • Old (standard): 2.5 gallon per minute (GPM) • New: 1.5 GPM • Savings: 1.0 Gallon per Minute • 30 min showering = 30 gallons per day • 365 days = 10,950 gallons per year $100/year savings for electricity and water (~$60/year savings for natural gas) UNR Renewable Energy Minor October 18, 2016

  11. 11. A Great Investment • Investing in home efficiency is one of the best investments you can make • Significantly reduces long-term energy costs • Guaranteed return on investment, often exceeding 10% • Makes you more comfortable while saving you money UNR Renewable Energy Minor October 18, 2016
  12. 12. 24
  13. 13. Economic Analysis • Efficiency improvements: – $7,000 cost – $3,500 annual savings – 2 year payback / 50% Return on Investment • Solar hot water: – $6,700 cost - $2,500 rebate = $4,200 out of pocket – $420 annual savings – 10 year payback / 10% Return on Investment • Home value increased by $52,000 in 2 years! – At least half attributed to energy improvements 25 UNR Renewable Energy Minor October 18, 2016

  16. 16. Net-Zero Energy • The final step to making my house Net-Zero Energy is to replace the oil furnace. • Will have a ground-source heat pump installed. • Exchanges heat with the ground to provide heating and air conditioning. • Cost: $33,000 • Federal Tax Credit: 30% UNR Renewable Energy Minor October 18, 2016

  21. 21. 33 Nevada Energy Consumption & Costs
  22. 22. Economic Development Nevada spends $8 Billion each year on imported fossil fuels. (natural gas, coal, oil) • By 2030, we could have 100% renewable electricity, and 50% reduction in oil imports • By 2040, we could have 100% renewable energy across all sectors • Retaining $7 billion would create 100,000+ jobs UNR Renewable Energy Minor October 18, 2016
  23. 23. Residential • Nevada homes spend ~$1.5 Billion out-of- state each year on fossil fuels • 500,000+ homes in Nevada need efficiency upgrades x $7,500 = $3.75 billion impact • 500,000+ homes could install renewable energy upgrades x $20,000 = $10 billion impact • Auditors, HVAC, electrical, plumbing, insulation workers, solar installers needed UNR Renewable Energy Minor October 18, 2016
  24. 24. Commercial / Industrial • Nevada businesses spend $2.0 Billion out- of-state each year on fossil fuels • Deep efficiency improvements = 30%+ savings • Rooftop solar • GSHP under parking lots • Solar shade over parking lots UNR Renewable Energy Minor October 18, 2016
  25. 25. Transportation • Nevada spends over $5 billion annually on imported oil and transportation fuels. • How can we transform the Transportation sector? • Improve Bike-ability • Electric Vehicles • Light Rail • High-Speed Rail or MagLev Trains UNR Renewable Energy Minor October 18, 2016
  26. 26. Energy/Water Nexus • Efficiency and renewables reduce water waste • Covering half of Lake Mead in solar would: • Reduce evaporation equal to Nevada’s water allocation from the Colorado River • Produce more electricity than all of NV Energy’s fleet of gas and coal plants UNR Renewable Energy Minor October 18, 2016
  27. 27. Next Steps • NSHE Endowment: Divest from Fossil Fuels • 2017 Legislature: o Set Statewide Goal (100% renewables by 2040) o Green Bank to finance projects o PERS: Divest/reinvest ~$2-$3 Billion UNR Renewable Energy Minor October 18, 2016
  28. 28. What can you do? • Change your lightbulbs to LEDs and install a high efficiency (1.5 GPM) showerhead today! • Hire a certified energy auditor to see what other improvements you can make • Talk with UNR about how they can save energy • Contact your elected officials to let them know that this is the future you want for Nevada!
