ScanPlan: HVAC Load & Ducts

This update adds two new planning tools and real accuracy improvements across your load calculations: Dehumidifiers — Size a whole-home or room dehumidifier from area and dampness level. The moisture and heat load automatically splits across the rooms it serves and flows into your cooling calculations and report. Geothermal Sizer — Size and compare GeoStar water-to-water geothermal systems against your existing heating fuel, with a shareable operating-cost comparison report. Energy Savings Lab — Try what-if upgrades — insulation, air sealing, new equipment — in an isolated sandbox that never touches your saved project. See projected annual savings before committing to a scope. More Accurate Infiltration — Blower-door test results (CFM50) now drive a validated infiltration model for more accurate heating and cooling loads on tested homes. Smarter Design Conditions — Outdoor design temperatures now pull automatically from local weather data for your project's exact address. Your county's climate zone is shown separately, clearly labeled as an estimate rather than mixed in as site data. Existing Cooling Accuracy — Tell us what cooling equipment, if any, is already installed so energy estimates reflect the real system instead of assuming central air everywhere. Also includes floor-plan door/window placement refinements, updated legal disclosures on generated reports, and other fixes.
