Logan Walsh, CGHA — Accurate Appraisals NY
High-performance homes with Passive House envelopes, solar arrays, and geothermal HVAC systems command premium prices, but only when accurately modeled in the appraisal report.
We evaluate air-tightness, thermal resistance (R-values), triple-pane glazing, and HERS index scores to quantify mechanical operating efficiency.
Converting net-metered solar PV generation and battery storage savings into Net Present Value (NPV) added directly to the property's contributory asset value.
Generalist appraisers often default to standard comps, penalizing green homes. We isolate high-performance features via paired sales data to substantiate the green market premium.
Every green appraisal incorporates the official Appraisal Institute Energy Addendum.
