Why Buy It?Why Buy It?

Buying this house will show you the amount of money you could have in your wallet. Located in Boise, Idaho, it has an

outstanding view of Swan Falls Dam on the Snake River. The dam contains a

hydroelectric power plant which will supply the electricity for your new Green Home! However, expenses may be a little costly, but don’t worry, it will pay for itself in the

end, PLUS MORE!

HowHowItIt

WorksWorks

1. Water rushes through the penstock and turns the turbine.

2. The turbine spins the generator

3. Electricity goes to the transformer in the powerhouse

4. Transformer transforms the electricity into a usable form

5. Electricity travels through the power lines and goes to homes and businesses.

Benefits of HydroelectricityBenefits of Hydroelectricity

• Renewable• Minimal pollution• Plays a major role in reducing

greenhouse gases• Low operations and maintenance

costs• Reliable and proven over time• Long lifetime

SolarSolar EnveEnvelopelope HouseHouse

1. Low winter sun’s rays pass through the glass heating the air within.

2. That warm air rises followed by the cooler air from below the house.

3. When the heated air reaches the top of the house, it's drawn through the air passageway between the roofs of the two structures, down through the same channel at the north wall of the house, and back into the crawl space where it heats two feet of backfill spread atop the structure's well-insulated foundation.

How IHow Itt WorksWorks (( ))

1. Summer sun (higher in the sky) can't feed as much heat into the house because of the angle at which it strikes the windows.

2. An outside vent pipe (routed underground) which feeds into the crawl space at the north side of the house.

3. A controllable damper on this pipe allows the desired amount of fresh outside air to be drawn through both the crawl space and the air channel between the shells cooling the structure

ExtraExtra FactsFacts

• Constantly circulates by convection • Circulation reverses during the night• Not only tempers the inner structure,

but also warms the thermal mass beneath the house. (can maintain warmth up to 3 days)

Passive Solar HeatingPassive Solar Heating

How It WorksHow It Works• (Winter)1. The sun’s rays enter the house through

large windows.2. The tile flooring, or in our case, the

flagstone flooring and salt-treated timber walls, absorb the heat and stores it.

3. The heat is released slowly throughout the day and night.

• During the summer however, the sun is higher up in the sky throughout the day so the roof will block more sunlight to cool the house rather than heat it.

BenefitsBenefits

• Little to no operating costs• Minimal maintenance costs• Emits no greenhouse gases

Extra FactsExtra Facts

• Does not actually include any sort of mechanical heating device.

• Functions by having features that absorb heat and then release it slowly to maintain the temperature within the home. (large windows, stone flooring, and brick walls.)

• Can reduce heating bills by almost 50 percent.

GrayGray Water Water

CollectionCollection

GrayGray Water and How It Water and How It WorksWorks

• Any water that has been used in the home, except water from toilets

• You can even use old water that you gave to your pets or water from a fish bowl

• Bathwater is considered the best source of gray water

• Easiest place to collect gray water is from your clothes washer

• Easy to do at home, and for no cost

Benefits of Benefits of GrayGray Water Water• Lower fresh water use• Less strain on failing septic tank or

treatment plant• Gray water treatment in topsoil is highly

effective• Ability to build in areas unsuitable for

conventional treatment• Less energy and chemical use• Groundwater recharge • Plant growth • Reclamation of otherwise wasted nutrients
