1
(Thermal Solar Heating and Cooling)
Insulation
Insulation blocks the passage of temperature from inside out and visa versa.
2
(Thermal Solar Heating and Cooling)
Dense Mass
Also known as Thermal Mass absorbs heat. Example: concrete, earth, stone, water. The more dense the mass the more temperature it will hold, hot or cold.
3
(Thermal Solar Heating and Cooling)
Alternatives for Insulation (3 points)
-cardboard
-paper
-recycled jeans insulation
4
(Thermal Solar Heating and Cooling)
R-Value
Is the measurement of resistance of heat flow through a given thickness of material. A high R-Value is more resistant.
5
(Thermal Solar Heating and Cooling)
Insolation
Insolation is the amount of sunlight hours in a day. The winter average should be used to calculate system sizing.
6
(Thermal Solar Heating and Cooling)
The reason to build with tires (6 points)
-The are indigenous to Earth
-The rubber encased earth is resilient to earthquakes.
-They only need to be gathered and used.
-They won't burn when packed with earth.
-When packed with earth they are a dense mass that will hold heat.
-A tire is it's own foundation.
7
(Thermal Solar Heating and Cooling)
The components that keep the Earthship cool.
Cooling is by convection using cooling tubes to take cool air from the earth and ventilation through high placed windows on the south side of the building.
8
(Thermal Solar Heating and Cooling)
The components that keep an Earthship warm.
Solar gain that comes through the windows is absorbed by dense mass (densely packed tires and the insulated berm)
9
(Thermal Solar Heating and Cooling)
"The Grid"
"The Grid" is a centralized source of power (electricity) that is expensive, inefficient, corrupt and destructive to the planet. It is a fragile and antiquated system that is subject to governments, corporations and weather.
10
(Thermal Solar Heating and Cooling)
Convection
The movement of heat from one place to another by movement of liquid or gas.
11
(Thermal Solar Heating and Cooling)
Conduction
The process by which heat is directly transmitted through when there is a difference in temperature without movement of material.

(Thermal Solar Heating and Cooling)
The 6 needs (points) on Earth
-Comfortable shelter
-Water
-Food
-Treatment of human waste
-Treatment of garbage
-Electricity
