5. 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

6. Attic & Wall Insulation

7. Window Heat Loss About 10%-15% of a homes total energy is lost through windows Install fewer windows Use multiple panes

8. Building Materials MUD BRICK STRAW BALE Which material in these photos would be the best insulator and why? LOGS BRICK ROCK

10. 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.

11. Caulking a window on the inside and outside in order to make the window more “air-tight.”

12. Weather striping placed around door in order to make the door more “air-tight” when closed.
