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 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 BACKGROUND INFORMATION Types of Insulation: Batts Blankets
Loose-Fill (most common) Foam Rigid 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
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 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 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 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 CONCLUSION In order to take advantage of the sun for solar energy, a house must be properly insulated to conserve the energy REFERENCES Solar Power. Wikipedia. Oct. 5, 2005

Fast twitch fibres depend on glycolysis to supply their ATP and are put to use in power activities like weight lifting and sprinting. Myoglobin in muscle cells helps extract oxygen from blood with its high affinity for oxygen. Most skeletal...
The ordinary demand equations are Income Changes and Perfectly-Complementary Preferences Quasi-linear Indifference Curves Income Effects A good for which quantity demanded rises as income increases is called normal. Therefore when a good is normal its Engel curve must be positively...
Drug Identification & Toxicology. Toxicology:. The study of poisons. Identification of drugs a person may have used . Effects of drugs on the body. Objective: SWBAT Define key vocabulary terms associated with the toxicology unit.
Costs And BenefitsThe big benefit. Automatic checking. That is, "cheap" bugs. The sooner a bug is found, the less expensive it is. Annotated code finds many more bugs (with less noise) than un-annotated code
