Geothermal Powered House
Sonoma, California
Sonoma, California Allows graywater collection
The GeysersA complex of 22 geothermal power plants located 72 miles north of San Francisco, which is near Sonoma.
Largest geothermal power plants in the world
Direction
The house will face west because of the sun
The sun rises in the East and sets in the West.
Too much sunlight will fade the color of the bamboo flooring.
Geothermal Power Plant
Water and the earth are used to create electricity
It is the same process to create electricity as with fossil fuels, but no fossil fuels are used
3 typesDry steam Flash steamBinary cycle

General Advantages & Disadvantages
No fossil fuels used
No need to transport
Only admissions are steam and small amounts of gases
Only able to be built on or near tectonic plates
Dry Steam
Hot steam and or water from the ground is routed to a turbine which powers a generator that creates electricity
Flash SteamUses hydrothermal fluids above 360°F
Fluid is put into low pressured tank which causes it to vaporize or “flash”
Vapor→ turbine→ generator→ house
Extras can be “flashed” again
Binary Cycle
Low temperature water is mixed with a secondary fluid (hence binary) and are sent through a heat exchanger which causes the secondary liquid to flash which powers turbines
Binary cycle (continued)
Closed system so produces no waste
New and up and coming more and more of these kind of plants are being built
Tankless instant water heater
Tankless water heaters use natural gas or propane to heat water only when water is neededWhen a faucet is turned on the heater begins to heat water as it passes through a copper heat exchanger84% of the energy as heat is used so it is extremely energy efficient Faucet is turned off and heater also shuts off so uses no phantom power
Tankless instant water heater
The tankless instant water heater replaces a conventional water heater.
Adavntages
Reduces water heating costs
Last longer
Disadvantages
Water flow slows when providing water for more than one appliance
More costly to install
Recycled glass countertops
Advantages Old glass that does not break down is broken into small pieces and mixed with fly ash and concrete which rids the environment of these wastes.They are recyclable.
Disadvantages very expensive to make and install.
It replaces counter tops that are not recyclable.
Graywater Collection
Any washwater that has been used in the home, except water from toilets can be reused for other purposes.
Graywater collection can replace fresh water.
Pipes transport the water from inside to the outside of a house.
Advantages & Disadvantages of graywater collection
AdvantagesLower fresh water use
Less energy & chemical use
DisadvantagesStudies suggest high levels of sodium
PH levels rise
Bamboo Flooring Stalks are cut from thick plant walls, and then boiled in a solution of lime & boric acid.
The solution drives out the starch of the plant which attracts insects that destroy wood.
Bamboo flooring takes the place of hard wood flooring.
Advantages & Disadvantages of Bamboo Flooring
AdvantagesEnvironmentally better than hardwood flooring
Less in cost
Disadvantages Prone to denting/chipping
The color of the floor can fade
L.E.E.D.
Materials and resources- the reusable glass countertops mixes fly ash and prevents it from going into environment.
Water efficiency- tankless instant water heater reuses water
Innovation & design process- the house has many “green” features.
