| A Do-It-Yourself Guide To Energy
Star Home Sealing Energy Star Home Sealing Guide... (2 MB pdf) Leaky ducts may lose lose 15% to 30% of your heated or cooled air ---- more on duct sealing |
This
is a very well done guide to sealing up air leaks in your home. Lots
of good how-to pictures. A couple small add-ons I would make: - Replacing older can lights so that you can insulate right over them is a fairly easy DIY job -- it has the advantages of both reducing heat loss to the attic and getting some heat gain from the can light to the room. - The method they give for determining if you have enough insulation is goofy. Instead, use the Insulation Upgrade Calculator or one of the online insulation guides to determine if your insulation is sufficient for your climate. - For insulating over existing insulation, I like blown in cellulose. Its easy, insulates very well, is resistant to air currents flowing through it (see study below), and is easy on the planet. |

Very
nice set of plans for double pane interior storm window that can be made for
about $1 per sqft.As usual, Guy offers a very detailed and clear set of instructions. These are somewhat similar to the ones I made from Mylar (just below), so you can compare the two and see which will work best for you. |
|
Dual Pane Mylar Film Inside Storm Windows
Gary |
Picture
plans for making an dual pane inside storm window with an R value of 2.
The Mylar is quite clear, and the thermal performance with two panes is about twice as good as a typical single pane storm window. Here is an example of a commercial kit to build a similar dual layer interior storm window -- there may be many others. About 5X the cost, but it looks like a good design. |

A
really cheap and quick way to insulate windows that you don't need a clear

|
| The half insulating shutter -- light + insulation |
The
idea is to put high Rvalue rigid insulation foam board over part of the
window while leaving the top part uncovered to allow light in.It seems like this is a nice combination of light, view, and insulation? Full length insulating shutters can still be used over the panel at night. |
|
Top-down, Bottom-up thermal shade insulates when part open Details... Note: the combination of double glazed low-e window + double Mylar inside storm window + insulating shades with side tracks gives an R8.3 total for this window! |
A
thermal shade that can be drawn from the bottom upward allows lighting and
some views out a window while still providing good insulation for the part
of the window that is covered.It should perform similar to the Half Shutter listed just above. Details... |
|
Insulating Shutter Condensation Calculator, Dave |
Loose
fitting insulating window treatments can lead to condensation buildup on the
window. The problem depends on room humidity, outside temperature, and
the window and insulating window treatment R values. Dave has worked
out a very nice
Window
Condensation Calculator to determine if you are likely to have a
problem.Note that tight fitting insulating treatments that don't allow much air circulation between window and treatment won't have this problem. Thank you Dave! |
|
3M type shrink fit window films
|
This
window film is widely available at hardware stores. You put double
back tape (included) on the window frame, then apply the film onto the tape,
then use a hair dryer to shrink it tight.In addition to adding about R1, it can be helpful in stopping drafts. But, it is normally applied in such a way that you can't open the window. Removing it will destroy it. There is a very slight distortion of the view out the film. Cost is about 30 cents/sqft. Life claimed is one year, but I think it will go at least 2 if you leave it in place. |

The
Kotatsu is a low table with a heat source mounted to the bottom surface of

It is said to keep your entire body comfortable even when the room temperature is low. (Thanks to Nick Pine for suggesting this) I guess that having a small space heater under your desk is a less refined variation on this. |
| Heated Clothes |
These
are one version of battery powered, heated vests. The vest is made
with very rine, flexible heating wires through it. The heat from the
vest keeps your core temperature up, which convinces your god that it can
maintain good circulation to your extremities, and this makes you feel warm
all over even when the room is to cool for comfort.If you have had direct experience (good or bad) with this or other heated clothing please let me know... |

The Power Hogs For most people, these will be things that use the most power -- controlling them will cut most peoples electricity use by half -- maybe more. |
|
|
The Power Hogs The list to the right shows where most of your electricity goes. Cutting electricity use of a typical US home in half saves:
|
Refrigerators -- Old ones (and even not so old) can use over 1200 KWH
a year. A new energy star 20 cubic feet can use as little as 400 KWH per year. A saving of 800 KWH per year -- maybe more. This is what we saved ... |
|
Computers -- A PC plus peripherals can use over 1000 KWH a year. It is very easy and cheap to cut this by 80%. This is what we saved ... |
|
|
Lighting -- Changing to compact fluorescents can save over 1000 KWH
per year. This is what we saved ... |
|
|
TIVO -- and TIVO like digital TV recorders. These devices are
always on and consume around 50 watts 24/7, or about 500 KWH per year. There is a new energy star program coming out on these -- I'd hold off and wait for Energy Star models. |
|
|
TV's -- Some TV's can use as much as 450 watts! At 8
hours of TV a day, this is 1300 KWH a year! Use one of the lower power technologies (LCD or DLP). Look for OLED TV's -- coming soon -- much lower power. Article on this with power usage for many models ... Selecting our new energy efficient TV... |
|
|
Washing and Drying -- A load of cloths washed and rinsed in hot
water, and then dried in an electric dryer uses about 10 KWH! --
this is 3600 KWH a year at one load per day. Most of this energy
goes for heating water. Use cold wash/cold rinse and a solar dryer (cloths line) to cut this to near drastically. Front loading washing machines also help. |
|
|
Dumb Habits -- Just turning things (lights, TV's, ...) off when you
are not using them can save several hundred KWH per year. This is what we saved ... Get the kids involved ... |
|
|
Phantom Loads -- Many electronic gadgets (TV's, entertainment
centers, microwaves, chargers, ...) use power even when switched off. Here is how to kill these power vampires ... This can save you several hundred KWH per year. |
|
| More Power Hogs -- some less common power hogs | Radon Fans -- Radon mitigation fans run 24/7 and can use up to 130 watts -- this could amount to 1100 KWH per year. This article advocates trying a passive system first, and only going to a fan system if Radon test levels come back high. Passive systems can easily be converted to active systems. If an active system is needed, I would always try a small fan first -- some are as low as 40 watts. |
| Hot Water Recirculation Pumps -- These systems circulate hot water so that you always get instant hot water even at taps very distant from the hot water heater. The problem is that if you choose the wrong kind of installation they can be horrible energy hogs --this is our experience ... Would you believe $3200 worth of wasted propane over 8 years? | |
| Battery Powered Tool Chargers -- Battery powered tools come with a charger that most people just leave plugged in all the time -- if you own several of the tools, these idle chargers can add up to a significant phantom loads ... | |
| "Half" Project Electricity Saving Ideas |
These are the energy saving projects that we used in cutting our electricity
use in half. You might be able to use some of the yourself. |

thoughts on the energy used by pilots lights (surprisingly large), and how
to reduce or eliminate this.And, a rather unusual strategy for heating your hot water with just the energy from a pilot light. |
| Gas Pilot Light energy use
|
Article
studying gas use by pilots on gas fireplaces. A gas fireplace pilot
(and probably other gas pilots) use 7.3 therms of gas if left on all year,
and almost 100 lbs of greenhouse gas.(1)Note that some sources report much higher gas use by pilots-- more like 5 therms per month (1) Turning off pilots on gas appliances that are not going to be in use for a while would be a good way to save some energy and reduce greenhouse has emissions. (1) Home Energy Magazine has corrected the 7.3 to 73 therms here... (Thanks to Ned for finding this) |
| Very Efficient Chest Refrigerator Chest Fridge Full Article (68K pdf) This article is from the Mt Best -- Australia solar house site: http://mtbest.net/ A very interesting solar house with several unique features, and a bit more info on the chest fridge. Another approach here: The thermostat shown on
this page is reported to allow you to use a chest freezer as a refrigerator
with large energy saving: |
This
refrigerator, which is a converted chest type freezer uses only about 0.1
KWH per day. See the article for details. Latest update includes
a design for a low standby power thermostat.Apparently not all chest freezers are created equal, as some do not report quite as dramatic an energy saving as Tom reported in his paper -- so if you are getting a new chest freezer for this, pick an efficient one to start with. One person reported 0.3 KWH per day (108KWH/year) on a newer Kenmore freezer that was EPA rated at 279KWH per year. So, something like a quarter of a typical, similar size conventional (upright) refrigerator seems easily achievable. |
| SunFrost Refrigerators http://www.sunfrost.com/refrigerators_main.html

I
don't normally plug commercial products, but the energy consumption of
SunFrost is about 40% less than comparable new refrigerators from the GE's

| Make a Fridge? Description of the fridge making kit and instructions for making a fridge from it ...
More Details (pdf)
Another kit fridge -- DIY System Kits:
|
This
is just a thought. NovaKool (maybe others?) offers a kit for people
who want to make their own fridges. It consists of a compressor,
evaporator, condenser, controls, and pre-charged tubing -- all the guts of a
fridge. It is intended for boat or RV owners who want a built in fridge.
It uses the DanFoss compressor, which is reputed to be efficient.If you wanted to make a very efficient fridge, this kit would allow you allow you to build the box with as much insulation as you want, it could be top opening, and the compressor could be located in an optimal spot. On just a rough guess from their specs, you might get down to 0.1 KWH per day for a very well insulated 8 cubic foot fridge. Unfortunately the kit is not cheap, but this still might pay well for off-grid PV users. If anyone has tried this (or similar), please let me know how it turned out -- Gary Note -- see next entry for Ray's very nice example of using one of these kits. |
| Build DC
Powered Refrigerator or Freezer! Full Construction Details:
|
This
is a really nicely done homemade refrigerator that uses a refrigerator kit
intended for custom refrigerators on boats.Ray started with a 13 cuft conventional fridge. The existing compressor/evaporator were removed, about 4 inches of rigid foam insulation were added to the outside, then, an efficient DC refrigeration unit (similar to the ones listed just above) is installed to provide the cooling. The condenser coil and compressor are located away from the fridge in the cool basement for more efficient operation. The fridge uses about 100 KWH per year -- about one quarter what an Energy Start fridge of the same size would use! This would make a very efficient off-grid refrigerator that could run directly from the battery bank. Ray has a lot of other interesting projects on his site ... |

A

| Drying Clothes | |
| Conventional clothes dryers
are a major energy user in homes. A Canada study shows that dryers typically
use 930 KWH a year to do 416 dryer loads (2.23 KWH per load). Nearly all of
this heat energy simply expelled outdoors (wasted). In addition, as the dryer vents air outside, fresh air is pulled into the house to replace the vented air. This fresh air has to be heated or cooled (depending on season) to room temperature -- this can easily add another 300 KWH plus per year. Its amazing to me that this very large energy sink does not get more attention. For many homes, the clothes dryer will be the largest consumer of energy in the house after water heating. Here are some ways to reduce energy use that goes into clothes drying. |

| Condensing Dryers LG description of condensing dryers... Energy stats for a number of condenser dryers... |
Condensing
dryers do not vent the dryer exhaust outside. Instead, they run the
exhaust through a heat exchanger that condenses out the moisture, and then
circulates the now dry air back through the clothes."How
much energy does it consume? There are several types of condenser dryers, and some do a better job of saving energy than others. There are also differences in drying performance. So, make a careful selection. |
| Converting a
Clothes Dryer to Use Solar Heated Attic Air All the details on Randy's solar dryer conversion... |
Randy
has worked out a way to convert a conventional d dryer so that rather
than using an internal heater to make hot air do dry the clothes, he uses
hot air produced by his unique solar attic collector.This cuts the cost and energy use and CO2 emissions to do a dryer load by a factor of five! |
| Venting the dryer inside the house to recover
the dryer heat
|
A lot of heat is wasted by cloths dryers that take house air, add energy to
it, blow it through the cloths, and then exhaust the heated air outside.
I have seen schemes that range from just venting the dryer to the inside of the house with a nylon sock tied over the end for lint control (dry climates only), up to the pretty exotic dryer heat exchanger offered (in Europe) by Electrolux. If you have tried a scheme (or have an idea for a scheme) to extract dryer heat, I would like to hear about it (whether it worked or not) Gary. Update: This is the simple scheme we are now using to recover heat from our dryer -- yearly saving is 630 KWH. SAFETY NOTE: If you have a gas dryer, BE CAREFUL with what
you do with the exhaust, since it has combustion products from the gas
flame. |

Efficiency of various types of lights ... |
It is a
just plain no-brainer to use fluorescents and compact fluorescents.
They are far more efficient, last much much longer, and will save you a ton
of money and greenhouse gas emissions. Most utility companies offer some form of rebate program for buying CFL's -- making it even more of a no-brainer!
Some have expressed concerns about the small amount of Mercury contained in
CF's and fluorescents. This does not appear to be much of a concern,
but have a look at the EPA fact sheet in case you break one someday. |

This
is the latest step in trying LEDs. This LED is designed as a
retrofit for regular can lights. It provides lots of warm light while using only 10.5 watts, and claims a 20 year life. The installation was easy, and offers the additional opportunity to seal and insulate the can at the same time the LED is installed. All the details on replacing can lights with LEDs... |

Popular
Mechanics magazine did a careful side by side comparison of a standard
incandescent light bulb to seven compact fluorescents.They compared color temperature, color, brightness, face color, and reading. The result was that ALL 7 CFL's SCORED HIGHER THAN THE INCANDESCENT. This should satisfy anyone's doubts about the light quality of CFL's. |
| Daylighting
|
Using
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. 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). |
