Annual Ventilation Cost Range

Low-end Estimate ${{(ctrl.annualVentCosts.exist | number:0) || '???'}}

• Older home
• Leaky ({{(ctrl.iCV.cfm50.exist / ctrl.inputs.livingArea / 8 * 60 | number:0) || '??'}} ACH₅₀)
• 15 CFM ventilation required

High-end Estimate ${{(ctrl.annualVentCosts.nu | number:0) || '???'}}

• Newer home
• Built to IECC-2012 or IECC-2015
• Air tight ({{(ctrl.iCV.cfm50.nu / ctrl.inputs.livingArea / 8 * 60 | number:0) || '??'}} ACH₅₀)
• {{(ctrl.iCV.ventCFM.nu | number:0) || '??'}} CFM ventilation required
