SOLAR INSULATION PRINCIPLES

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.
• R-Value measurement of how well a material
  resists the flow of heat
• Greater R-Value ? Greater resistance

3
BACKGROUND INFORMATION

• Types of Insulation
• Batts
• Blankets
• Loose-Fill (most common)
• Foam
• Rigid

4
ROOF/CEILING

• One of the main causes for energy loss
• 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

5
WINDOWS/SKYLIGHTS

• 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 summer, a great deal of heat enters through
  windows, especially skylights

6
WINDOWS/SKYLIGHTS

• Solution
• Movable Insulation
• Types
• Sliding Panel
• Shutters
• Window Mats
• 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

7
WINDOWS/SKYLIGHTS

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

8
OTHER INSULATION

• Doors should have fiber glass insulation with a
  R-value of R5-9
• Heat storage vaults and heat transport tubes
  should be insulated
• 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
