Blower Door

• 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

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).

Economic Analysis (LED Lights)

Would you give me $100 today, if I offered to pay you $10/month for the next ten years?

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%


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)

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


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

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%

Nevada Energy Consumption & Costs

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


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


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


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


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


Next Steps

• NSHE Endowment: Divest from Fossil Fuels• 2017 Legislature:

o Set Statewide Goal (100% renewables by 2040)

o Green Bank to finance projectso PERS: Divest/reinvest ~$2-$3 Billion


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!
