daylighting not only provides better and more pleasant lighting, it saves
energy and greenhouse gas emissions.
|
| LED Holiday Lights Almost all of the usual places that sell holiday lights now sell the LED lights. Prices still vary a lot, so it worth shopping around. We got ours a Costco for about $10 per string.
|
LED
holiday lights are safer (no heat), last a very long time, and look
great. They also use much less energy and significantly reduce
greenhouse gas emissions. The energy saving can be 90% or more.A typical 100 light LED string uses less than 4 watts! They have an expected lifetime of 20+ years. With the LED holiday light prices dropping, the payback period can be as small as a season or two (considering both lower operating cost and longer life). |

It flows out the shower nozzle, over your bod, and down the drain taking 95% or so of the energy you just spent heating it. The gray water heat exchanger uses the heat in the drain water to heat the incoming water. |

Mother
Earth News Article, Issue 196Good article on building and using “hoop house” greenhouses, which provide a very low cost per sqft greenhouse. Some construction detail. This technique could also be used for inexpensive sunspace for generating solar heat for your house. Many other construction variations here: Sunspaces Comment: This type of sunspace can be built very inexpensively, and can provide substantial heat to an attached house, and some plant growing space for some of the year. The best idea for transferring the maximum amount of heat to an attached house is to 1) build the sunspace large, 2) include very little thermal mass in the sunspace, 3) transfer heat during the day, and close off house to sunspace connection at night, and 4) do something to keep the sunspace floor from absorbing heat (e.g. garden bark covered with black poly). The sunspace can also be built as a quarter of a cylinder against the house's south wall, rather than the full half cylinder version shown above. |

Bio-Solar House in Thailand Jan Krikke, Architecture Week
|
From the Architecture Week article:
"It's
an environmental dream: a self-reliant house that produces its own
electricity, water, and cooking gas. Solar energy powers the
air-conditioning, lights, and household appliances. Rain, dew, and
condensation from the cooling system produce enough water for a family of
four. Recycled water irrigates the garden, and surplus electricity is sold
to the power company or used to drive an electric car 30 miles (50
kilometers) a day." |

Mother
Earth News article, Issue 48, Nov/Dec 1977 describes a very simple collector
for heating a shop.The cost is kept down to almost nothing by using poly film glazing and some scrounged parts. If you can scrounge the blower from an old furnace and find some used lumber, this collector probably takes the prize for lowest cost per square foot -- about 10 cents per sqft. The payback period where I live is well under a month! |

This
seems like a pretty good idea for reducing summer heat gain on windows.
The shades block up to 90% of sunlight, and mount in vinyl frames (like bug
screens). It looks like they would work on a wide variety of windows,
including ones that would be difficult to handle with other shading
techniques. They do the shading on the outside, where its most effect.
It seems like a DIY version could be worked out. The Phifer SunTex material is said to be available at some home centers. Frames could probably be made from the same material that home centers sell for making insect screens. |

EFIS
provides a way to insulate on the outside of dry stack concrete (or other)
structures. This places the insulation outside the thermal mass, where
it can be effective in smoothing out temperature variations, and in
absorbing solar gain through windows (see entries above).The links in the left panel provide information on the various EFIS systems, and details on how they are installed. EFIS offers a wide variety of outside finishes for different looks. EFIS systems could also be used to retrofit insulation to existing structures. There have been moisture and mold problems with some EFIS installations, so be sure that you select a EFIS contractor with a proven track record in your area. |
