Common Misconceptions
• “My home is weatherized”• “I’ll replace my heating
system first”• “I need new windows”• “I’m installing solar
panels”
![Page 10: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/10.jpg)
Path to Home Energy Savings
![Page 11: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/11.jpg)
Step 1: No Cost / Low Cost
• Replace incandescent with compact-fluorescent light bulbs (CFLs) or LEDs
• Weather-strip doors and caulk windows
• Install storm windows or plastic sheeting
![Page 12: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/12.jpg)
• Reduce your hot water use:– Reduce hot water temperature to 120
degrees– Wash clothes in cold water and line dry– Install low flow shower heads and faucet
aerators
• Turn off and unplug computers, TVs, and other electronics. Stop Vampire power / phantom load!
Step 1: No Cost / Low Cost
![Page 13: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/13.jpg)

Step 2: Tune Up Energy Users
• Turn down the temperature. Install and use a programmable thermostat
• Insulate hot water pipes• Seal leaks on heating system ductwork and
around furnace filter cavity• Keep your heating system and appliances
operating efficiently:– Change furnace filter twice a year– Clean filters and coils of refrigerator, air
conditioner, and furnace– Regular tune-ups of furnace and boiler (by
professional)

Path to Home Energy Savings
![Page 16: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/16.jpg)
A Building Performance Institute (BPI)-
accredited contractor will look at your house as
a whole and assess air leakage, insulation,
appliances, and lighting. The contractor will
make recommendations to help you decide how
to upgrade your house in the most cost effective
way.
A. Energy Assessments
![Page 17: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/17.jpg)
• Blower Door Test– Fan that sucks air out
of your house drawing in air through any gaps and cracks
– Measures air leakage– Simulates a 30mph
wind on a winter day
A. Energy Assessments

A. Energy Assessments: Thermal Imaging Camera

and gaps in insulation

A. Energy Assessments
• Combustion and Distribution Efficiency Test– Measures efficiency of heating system– Identifies indoor air pollutants and improperly
vented appliances• Scheduling an assessment
– Typically takes 3-4 hours– Green Jobs Green NY provides free or reduced
cost assessments• After the assessment
– Modeling– Report of recommended measures, cost, energy
savings, payback
![Page 20: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/20.jpg)
Step 3: Whole-House Energy Assessment and Upgrade
A. Comprehensive energy assessment by Building Performance Institute (BPI) accredited contractor
B. Air sealing by BPI contractorC. Insulation installation by BPI contractorD. Furnace or boiler replacement with
high-efficiency model by BPI-contractor
![Page 21: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/21.jpg)
B. Air Leakage
• Our homes are full of holes and cracks that leak heated air out of the house and suck cold outdoor air into the house
![Page 22: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/22.jpg)
Infiltration & Exfiltration

Air out at upper levels= Air in at lower levels
The Stack Effect
![Page 23: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/23.jpg)
B. Air Leakage
• Because of the stack effect, priority spots to air seal and insulate are the attic floor, basement ceiling or walls, and where the house meets the foundation
• Can use caulk, weatherstripping, spray foam insulation to seal air leaks
• Best to hire a professional to use a blower door otherwise you will miss significant leaks
• Most insulation products don’t block air flow! You should always air seal first then insulate
• Many Home Improvement contractors are not aware of the above information.
![Page 24: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/24.jpg)
C. Insulation
• R- Values • Types of insulation
– Loose Fill– Blankets and Batts– Rigid Boards– Foam
![Page 25: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/25.jpg)
Increase Thermal Insulation Levels
Only 20% of homes built before 1980 are well insulated
Recommended Levels– Attics R-40 - 60– Walls R-20 - 30– Floor over non-htd space R-20 - 30– Basement walls R-11 - 19
![Page 26: PATH TO HOME ENERGY SAVINGS](https://reader035.vdocuments.net/reader035/viewer/2022062323/56815980550346895dc6bea1/html5/thumbnails/26.jpg)
D. Upgrade heating system
• Do this after air sealing and insulation. Size matters.
• Newest models are 80-95% efficient• A model with a 60% efficiency is
wasting $.40 of every dollar

Step 4: Upgrade Appliances
• Replace refrigerator and freezer (with Energy Star models)
• Always buy energy star appliances!• When buying new appliances buy the
most efficient model you can afford.

NYSERDA’s Green Jobs Green NY program offers free and reduced-cost residential energy assessments. Here’s how it works:
1.See if you are eligible: – Own 1-4 unit residential building– Household income under 200% median income
($147,600) for free audit, under 400% median for reduced-cost audit ($295,200)
2.Complete a program application. Must include 1 year summary of previous energy usage
3.Schedule an assessment with a BPI contractor

Choosing a Contractor
• Look for Building Performance Institute (BPI) accredited Contractors
• Ask lots of questions– What’s included in the assessment?– Credentials, certifications, references?– What incentives do I qualify for?
• Avoid single technology vendors

• Made up of 3-5 work-study students, mainly from Cornell. • Over the summer, main focus was outreach for NYSERDA’s Green
Jobs Green NY home energy audit program. Ran a table at a variety of events throughout Ithaca and Tompkins County (Green Gorges Expo, Juneteenth Festival, Cornell Staff Development Day, Grassroots!, to name a few)
• Followed up with “leads” gained at these events to maintain interest, also held a weekly energy raffle.

Other Projects..To Name a Few
• Worked with Tompkins County Planners to write a grant for New York’s Cleaner, Greener Communities Program, goal is to mandate home energy audits for homes that are listed for sale and create a market for energy efficient housing in Tompkins County.
• Currently working with Off-Campus Housing on creating a survey to gain data on student interest in energy efficient housing, hope is to address the split-incentive barrier in rental housing.
• Wrote DIY guides for home energy efficiency projects, working on incorporating these with home energy workshops.
