1. SOLAR INSULATION PRINCIPLES KATHLEEN MAYBERRY Objective: To explore insulation for houses, and additional techniques to conserve energy in order to take advantage of solar energy

2. BACKROUND INFORMATION Different types of insulation depending on needs and climate. Different types of insulation depending on needs and climate. R-Value: measurement of how well a material resists the flow of heat R-Value: measurement of how well a material resists the flow of heat Greater R-Value → Greater resistance Greater R-Value → Greater resistance

3. BACKGROUND INFORMATION Types of Insulation: Types of Insulation: Batts Batts Blankets Blankets Loose-Fill (most common) Loose-Fill (most common) Foam Foam Rigid Rigid

4. ROOF/CEILING One of the main causes for energy loss One of the main causes for energy loss Normally, uses higher R-Value than other areas of a house Normally, uses higher R-Value than other areas of a house If the house has an attic, the floor of attic should be insulated as well If the house has an attic, the floor of attic should be insulated as well

5. WINDOWS/SKYLIGHTS Solar houses have many windows and skylights (Passive Solar Heating) Solar houses have many windows and skylights (Passive Solar Heating) In winter, skylight allows solar energy inside. However, during overcast days, and nighttime they let a considerable amount of heat outside. In winter, skylight allows solar energy inside. However, during overcast days, and nighttime they let a considerable amount of heat outside. In summer, a great deal of heat enters through windows, especially skylights In summer, a great deal of heat enters through windows, especially skylights

6. WINDOWS/SKYLIGHTS Solution: Movable Insulation Movable Insulation Types: Types: Sliding Panel Sliding Panel Shutters Shutters Window Mats Window Mats Allows solar heat to enter when it is needed, and block solar heat when it is not needed Allows solar heat to enter when it is needed, and block solar heat when it is not needed Ex. Unwanted solar heat in daytime during summer Ex. Unwanted solar heat in daytime during summer

7. WINDOWS/SKYLIGHTS Prevents heat escaping during the nighttime, and non-sunny days Prevents heat escaping during the nighttime, and non-sunny days Inexpensive compared to other ways on insulating windows Inexpensive compared to other ways on insulating windows Other ways to insulate: Other ways to insulate: Double pane windows Double pane windows Insulated glazing windows, especially south-facing windows Insulated glazing windows, especially south-facing windows

8. OTHER INSULATION Doors should have fiber glass insulation with a R-value of R5-9 Doors should have fiber glass insulation with a R-value of R5-9 Heat storage vaults and heat transport tubes should be insulated Heat storage vaults and heat transport tubes should be insulated Insulation in floors above unheated areas Insulation in floors above unheated areas

9. CONCLUSION In order to take advantage of the sun for solar energy, a house must be properly insulated to conserve the energy In order to take advantage of the sun for solar energy, a house must be properly insulated to conserve the energy
