Efficiency and Solar �for Homes and Churches

2 of 24

Welcome

Since 2006, Viridiant, a 501(c)3 non-profit, has promoted sustainable construction across Virginia, providing technical expertise and verification for more than 30,000 green-built homes.

Our Community Energy Services division was launched in 2020 to provide public education and resources regarding home energy audits, rooftop solar, energy efficient mortgages, and more – especially for folks in the Richmond region

Clean Energy in Virginia

Utility-scale wind and solar:

  • Lowest-cost power source
  • Thriving due to high profit margins

Clean Energy in Virginia

Distributed “rooftop” solar:

  • On-site solar
    • Uneven price/quality
    • Need financing
    • Customers ignoring efficiency
  • “Community” solar: crippled by utilities’ minimum fees (other than low-income)

Clean Energy Deployment in Virginia

  • Efficiency works – but is VASTLY under-deployed.
    • Consumers don’t understand technology or its potential
    • Need easy, affordable financing
    • Construction industry/trades not trained or oriented towards best ROI
    • Multi-family: owners lack incentive to reduce residents’ utility costs
    • Churches…

Millions of homes under-insulated.

Severe duct leakage is endemic.

Incredibly high usage persists

Needed: Deep Energy Retrofits – at Scale!

Virginia has more than 3.5M housing units as of 2022.

To achieve equity, economic, and climate goals, we must get all of those as close to net-zero as possible in less than 30 years.

That requires more than 100K “deep energy retrofits” per year – starting now.

Current Support for Energy Efficiency Upgrades

  • Existing Virginia programs are meaningful
    • Federal low-income Weatherization Program
    • Utility rate-payer funded programs
    • RGGI funds
    • Federal funds via state/local housing agencies

  • 2021 Infrastructure Act and 2022 Inflation Reduction Act added 100s of millions more
    • Tax credits available now
    • Rebates coming by 2024
    • Other funds for states/localities starting to flow

Solar Economics

  • Size of array not important.
  • Installation price and productivity are
  • Most roofs not big enough for array that will meet entire annual demand.
    • That’s fine, can still be economic
    • Any offset of grid power is great!

Smart Savings

Home energy saving tips:

Cheap, easy DIY:

    • LEDs for everything
    • Insulate hot water pipes
    • Re-insulate line-set pipe to compressor
    • Address phantom load loss
    • Seal/insulate attic access doors
    • Get a home energy audit
    • Stop drafts
    • Address duct leaks

Bigger jobs:

    • Correct insulation
    • Improve HVAC design and equipment
    • Replace very old appliances with high-performance models
    • Go solar if you have a good site
    • Replace single-pane windows with high-performance models

Air Leaks in Homes = 15-30% of Heating and Cooling Costs
