Six tools for the Weatherized Tier. Rebate Check estimates the rebate, with and without the Wx Tier. Worksheet is the Manual J input worksheet and photo list for the Performance Pathway (upstate utilities only). Rate reference, Vintage reference and Design temperatures hold the program tables. Visit checklist lists what to have ready for each home.
An estimate from the program's published rates (Program Manual v3, effective 1 September 2026). Not a guarantee: the program pays what its review approves.
Check DAC status for the property address on NYSERDA's Disadvantaged Communities page. The zip code alone is not enough to tell.
Square footage: use the conditioned floor area, meaning the floor area inside the thermal envelope that is heated and cooled, leaving out unconditioned basements, crawl spaces and garages (Performance Pathway Input Requirements, page 6). The rate tables print the 1,000 sq ft cutoff but do not say which area counts, so confirm with your account manager if the home is close to 1,000. Equipment must also be sized to at least 100% of the heating load and serve at least 80% of the home's conditioned area (Program Manual v3, section 3.2).
What the program pays per project, by utility, DAC status, building size and category. Base is the standard rate. Wx Tier is the higher rate for homes that qualify for the Weatherized Tier.
Single-family homes under 1,000 square feet of total conditioned area are paid the apartment column at Central Hudson, National Grid, NYSEG, RG&E and Orange & Rockland. Con Edison has no size rule. Apartment amounts are per dwelling unit served, up to four units. Rebates are limited to 70% of total project cost, or 85% in a DAC or at Central Hudson. "N/A" means the program has no rate for that case. Geothermal new construction is always paid at the Wx rate where no Base rate is printed. The tables do not define which square footage the 1,000 sq ft cutoff uses; the Rebate Check tab assumes the home's total conditioned area.
What to have ready for each house so the Manual J can be run, and what to photograph if the home does not pass on program defaults. Tick items as you go.
From the program's Design Temperature Lookup Tool (zip code sheet: 2,155 zip codes, 23 ASHRAE weather stations). Use these outdoor design temperatures in the Manual J. The same zip code feeds the Worksheet tab and the CoolCalc inputs.
Rounded to whole degrees, rounding half away from zero. Accepted range is within 5°F of the program figure (Program Manual v3, section 3.2.1). Indoor design temperatures: heating 72°F or lower, cooling 75°F or higher. Outside the accepted range, the project goes to review unless AHJ or manufacturer documentation is attached.
The program's default R-value for each component, by building vintage and IECC climate zone. Stating a higher R-value than the default needs photos. The row for the vintage chosen on the Worksheet tab is highlighted. The suggested window type is Sealed's suggestion from typical windows of each era, not a program rule.
R-value applies to: "total assembly" means the whole wall, ceiling or floor assembly including framing and finishes. "Insulation only" means the insulation layer by itself, as in the program's Table 5.
The September program document printed "NYS 2002-2008 IECC" on two rows by mistake. The November update relabels the second row "NYS 2008-2009 IECC" and keeps the values. Zone 4 values come from the program's Prescriptive Incentive Calculator (v4, updated 5 October 2026). Homes built in 2016 or later are not in this table yet.
Vintage and zone pick the program's default R-values (Table 5). The zip code gives the program's design temperatures and fills in the climate zone. Year built and stories are CoolCalc inputs. For a home built in 2003 or later, photos are recommended but not required.
Photos stay in this browser tab and are not uploaded anywhere. Reloading the page clears them, so send them to the program with your documentation before closing the tab.

What to enter in CoolCalc. The values come from the inputs above, so fill those in first. Screen order follows the new CoolCalc.
Screen order follows CoolCalc's own walkthrough video of the new version ("What's new in the latest version of Cool Calc", recorded on its staging site), not the legacy version. The legacy order put HVAC systems last and had separate Dwelling info, Construction Profile and Infiltration screens. Screens may change before release, so confirm exact labels in CoolCalc.
Defaults and photo rules follow the NYS Clean Heat "Performance Pathway Detailed Manual J Input Requirements" (9/2026), Tables 2 to 6. Climate zone by zip code, the zone 4 defaults and the 2008-2009 label follow the program's Prescriptive Incentive Calculator (v4, updated 10/5/2026), Man J Input Guidance tab.
