INTRO TO EARTHSHIPS Self Sustainable, Eco- Friendly Dream Houses
An understanding of mechanical systems for most humans is limited to what is within reach of their fingertips. It is understood that when you flip a switch on the wall, a light comes on. When you turn on the tap, hot water comes out. When you pull the handle on the toilet, it flushes. Little thought is given to where the electricity comes from or what kind of nuclear waste was produced to generate it. How many of us even know where the power plant is that supplies our power? Few people ever wonder which water table is depleted to bring them water and what chemicals have been added to it. Where does the sewage go after it is flushed and which rivers and lakes are polluted by it?
Basic principles Heating & Cooling Power Generation Water Harvesting Waste Management Food Production Building with Recycled Materials
Passive Solar Heating Rocket Stove Radiant Floors Insulation Heating
Passive solar heating (1) Thermal Mass: Any material that helps you store the sun s heat. Usually very dense earth. Absorbs heat by day, radiates it back out at night Home must be south facing for max efficiency Right thickness of thermal mass is key. Too thick = heat being lost into extra mass Too thin= not enough storage Earthship Brighton had 2m walls Too thick! When using thermal mass in floors, they must remain bare
Passive Solar Heating (2) Glazing: Layers of glass arranged to allow maximum light in, while also keeping heat from escaping Must be custom made! Most expensive part, also most important. Takes 3 months to be made Traditionally at 90 degree angle to sun This will cause more wearing of windows and beams A rating is best. U-value: how much heat can travel through the material R-value: how much sun light can pass through You want LOW U , HIGH R
Rocket Stove (Masonry) Radiant Floors
Insulation Stops heat flow Rigid insulation board in structure (weight bearing) Compressible in inner divides of home Many varieties!
Passive Cooling Curtains Cooling
Passive Cooling Hot air rises Cold air sinks Custom windows allow for cool air flow through bottom trap, and warm air to escape through upper ventilation traps Better insulation = less infiltration Be aware of wind flow in your area Having bodies of water nearby helps!

Rainwater Greywater Blackwater We use around 150L/day per person! Quebec has 1000mm/year precipitation Water Re-using of water! Must use biodegradable/organic cleaning products for this to work
Rainwater 1. collected on roof 2. pre-filtration (debris) 3.storage (underground) 4. filtering 5.sent to house
Greywater What was used for showering, cooking, cleaning 1. grease removal through membrane 2. grey water planters 3. toilet flushing
Blackwater What comes from your toilet! 1. sifting through septic tank 2.overflow into a reed bed 3. soaking away of water into vegetation or storage
Reed beds Compost toilets Cess pool/ Septic tank waste
Grey Water Planters Greenhouse Plant Types Food production
Cement/Earth container Waterproof membrane Grey Water Planters Gravel, then sand, then soil Must be able to prune the plants Heat loving fruit and veggies work best Must be Alkaline!
Rammed Earth Tires Re-purposed wood, tiles, doors, etc. Glass bottle walls Bottle Bricks Building with recycled materials
Basic building steps Land Budget Plans (design + execution) Permits Locals Build storage Crew facilities BUILD!
Dig Your Holes
Plumbing and Wiring
Windows + Inner Earth Walls
modifications Thermal mass Rocket stove Outside waterproofing (not jus earth) Tilted roof (no snow) Moveable solar pannels
