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

Attic & Wall Insulation
Window Heat Loss
• About 10%-15% of a homes total energy is lost through windows– Install fewer windows– Use multiple panes

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• Cold air coming through cracks and gaps
sinks and is warmed by the air in the room setting up a convection current.
