For Planning & Professional Review: Green Home Predictor provides planning guidance based on available home information. It does not replace on-site inspection, official Home Energy Score or HERS procedures, blower-door testing, Manual J heat load calculations, licensed design, contractor judgment, or code compliance. Critical facts, final scopes, and installation requirements should be confirmed by a qualified professional before work begins.

Planning Better Retrofits Together

Successful home upgrades depend on clear facts, sensible project sequencing, and realistic expectations. Our 3-step retrofit process helps homeowners and contractors align on what to do first, how to budget, and how to deliver lasting comfort and efficiency.

  • 1. Score the Home: Establish a clear baseline of home facts, energy performance, and comfort issues before committing to major contractor bids.
  • 2. Explore Options: Identify priority upgrades, estimate potential savings, and map out available rebates, incentives, and financing pathways.
  • 3. Renew the Core: Sequence work logically—air sealing leaks and upgrading insulation first, then right-sizing heating and cooling systems for maximum performance.
  • Clear Communication & Execution: Homeowners get predictable results without unexpected costs, while contractors work from better-defined project scopes.
