Home Heat Loss

Home Heat Loss

• 10% lost through floor • 20% through windows and doors• 25% lost through walls• 35% lost through ceilings• 10% lost through drafts

Reducing Heat Loss From The Home

• Insulate (conduction)– Attic and wall Insulation – Double pane windows, – Building materials

• Seal (convection)– Caulk– Weather-strip

• Radiation– Orientation– Color

Window Heat Loss

• About 10%-15% of a homes total energy is lost through windows– Install fewer windows– Use multiple panes

• Radiation– Orientation– Color

Window Heat Loss• Cold air coming through cracks and gaps

sinks and is warmed by the air in the room setting up a convection current.
