What is the Home Upgrade Prioritizer?
The Home Upgrade Prioritizer ranks clean energy and efficiency retrofits—including attic air sealing, smart thermostats, LED retrofits, heat pump water heaters, heat pumps, and rooftop solar—by Return on Investment (ROI), payback speed, and carbon reduction.
In building science, 'efficiency before generation' is the golden rule: tightening the building envelope and reducing base loads first allows you to purchase a smaller, less expensive heat pump and solar array later.

Core Engineering Formula & Industry Benchmarks
Uses ASHRAE / AHRI seasonal efficiency metrics (SEER2, HSPF2, UEF, AFUE) and building-envelope conductive heat transfer (Q = U × A × ΔT) across heating and cooling degree days.

How to Use the Home Upgrade Prioritizer
Gather your baseline utility bills or project specs and enter your values for available retrofit budget, current home systems, and local energy prices.
Adjust the interactive sliders or numeric inputs to match your local utility tariff, climate zone, and system size.
Review the real-time calculated metrics—specifically projects ranked by ROI (insulation, heat pump, HPWH, solar, windows) and cumulative payback.
Toggle available incentives (such as the 30% Federal Clean Energy Credit or local utility rebates) to compare gross vs. net payback.
Run a sensitivity check by testing conservative, expected, and high-inflation utility rate assumptions.
Worked Example: Home Upgrade Prioritizer
Real-World Engineering Scenario: Home Upgrade Prioritizer
Start by entering your current baseline values for available retrofit budget, current home systems, and local energy prices based on your utility bills and property layout.
The simulator immediately calculates projects ranked by ROI (insulation, heat pump, HPWH, solar, windows) and cumulative payback, allowing you to compare your baseline cost against high-efficiency clean energy alternatives.
Adjusting one variable at a time—such as local tariff rates, system capacity, or available incentives—reveals the highest-ROI configuration before you commit capital.
Key Engineering & Financial Insights
Seal and Insulate Before Sizing HVAC
Upgrading attic insulation to R-49+ and air-sealing rim joists reduces peak Manual J heating/cooling load by 20%–30%, allowing you to buy a smaller, quieter, cheaper heat pump.
Heat Pumps Transfer Heat (300%+ Efficiency)
Even the best condensing gas furnace is capped at 96%–98% AFUE, whereas an inverter heat pump moves 3 to 4 units of ambient outdoor heat for every 1 unit of electrical energy.
Heat Pump Water Heaters Are Fast Payback
Replacing a standard 4,500W electric resistance water heater with a hybrid heat pump water heater saves ~2,500 kWh/year ($400–$600/yr) and dehumidifies basements for free.
Dual-Fuel Balance Point Optimization
If you have a hybrid heat pump + gas furnace system, setting your thermostat switchover to the exact economic balance point temperature prevents burning expensive gas in mild weather.
