1. Introduction
Zam Green (“we,” “us,” or “our”) respects your privacy. This Privacy Policy explains what information we collect when you use our website and tools, how we use it, and your choices. By using Zam Green, you agree to this policy.
1.1. Calculation methodology and data sources
Our rebate and savings estimates are produced using a defined methodology: we combine federal IRA (Section 25C) and HEEHRA parameters with state and utility program data where available, and we model energy savings using published efficiency assumptions (e.g., heat pump COP, fuel rates). We rely on official or authoritative sources (e.g., IRS.gov, Rewiring America, state energy offices, utilities). We do not sell or monetize the calculation logic. For a full description of our methodology and commitment to 2026 IRA accuracy, see our About page. Every calculator and rebate page includes visible links to Data Sources (e.g., .gov and .org) so you can verify program details.
