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 NEW!

Don't use duct tape for sealing -- example ... 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.

Insulate and Weatherize Bruce Harley Very, very good book on techniques for improving home insulation, reducing air infiltration, and sealing ductwork. The most complete and technically correct reference I have found.

Home Remedies for Energy Nosebleeds,

Bruce Harley, Fine Homebuilding, Issue 190 How to get articles from Fine Homebuilding ...

Fine Homebuilding Magazine, Nov 2007, Issue 190. A good article by Bruce Harley (author of the book just above) about finding and fixing particularly bad energy wasting defects in your house.

Global Warming #GWPImpact of Various Insulating Materials



www.buildinggreen.com/...

Alex Wilson, Building Green Some insulating materials have large global warming impacts because of the blowing agent used to make them.

Extruded Polystyrene (XPS) and closed cell foam in place polyurethane (SPF) are particularly bad.



Cellulose, polyisocyanurate board, expanded polystyrene and several others have very low global warming impacts.

This article looks a the global warming payback for insulation used OVER an insulated 2 by 6 wall -- the payback runs into several decades for the XPS.

Polyisocyanurate (Polyiso) board insulation is readily available, has a very high R value per inch, and low global warming impact -- seems like a good bet when rigid foam insulation is needed.

Insulation Fact Sheet (pdf) Fairbanks University Cooperative Extension Service A very good table providing information on all the common (and not so common) types of insulation. R values, application suitability, pro/con, max service temperature, ... Very Useful, and, as far as I can see, unbiased (which is hard to find in insulation info on the Internet).

See the sealing guides in this section or the Harley book for how to do the sealing.

Buried and Ecapsulated HVAC Ducts,

DOE Building America

Summary of buried and ecapsulated duct study... Heating or cooling ducts running through the attic can be large energy consumers compared to ducts run within the conditioned space. This study looks at a scheme for encapsulating the ducting in spray foam insulation and then covering the ducting with loose fill insulation. This brings the performance of ducts running through the attic to about the same level as ducts running through the conditioned space.

More on Duct Sealing AeroSEAL Duct Sealing System http://www.aeroseal.com/index.php This is a process for sealing ducts that works for the inside. It will reach areas of the duct system that are built into walls or otherwise inaccessible.

Here is a comment from the Greenbuilding Discussion Group ( http://www.buildinggreen.com/elists/gb_signup.cfm ):

"I have sealed many duct systems by removing the grills/registers and using UL-181 duct mastic on all the joints I can reach. I then seal everything accessible at the furnace that is accessible. Most of the time I get to below 6% (California code for new ducts) without touching anything else. If I don't get below 6% then I go to the duct runs that are accessible. Only very large duct systems, and those with ducts buried I can't get below 6%, but I'm usually close.

I know the person who developed Aroseal, you have to do some manual work anyway with larger holes (grills/registers ?) and you will only get as tight as the operator has time to sit around pumping more sealant into the ducts. It is a great process for inaccessible duct systems that can't be sealed otherwise."

Advanced Air Sealing,

From Paul Full Details ... Paul provides a good detailed set of instructions on how to design, build, and install inside Acrylic storm windows.



Multi-Wall Polycarbonate Inside Storm Window Gary These Multi-Wall polycarbonate inside storm window panels offer high R values , easy build, easy install, and are reasonable in price. Great for windows of irregular shape . Full How-To instructions provided.

Building Interior Window Insulation Panels,

from Guy Marsden's sustainable living website www.arttec.net/Thermal-Windows/index.html You can use this calculator to see the payback period for these windows -- for me it turns out to be about 3/4s or one heating season! 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 How-To Picture Plans ... 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. NEW Life of Mylar inside storm windows ...

Simple, Clear Acrylic Inside Storm Windows Gary Very simple inside Acrylic storm windows. Absolutely clear and non-distorting. They return 50%+ on your tax free, inflation protected investment, and may qualify for rebates in your state. And, save 100+lbs of greenhouse gas emissions per year for a typical window!

AND, The Card Board Shutter

Based on the popularity of this Bubble Wrap window treatment, here is a Cardboard Shutter A really cheap and quick way to insulate windows that you don't need a clear view out of. Added some small updates to instructions 11/13/05.

Instruction sheet added 8/15/06

Reported life of bubble wrap added 2/27/07 Another cheap (but very effective) window insulator Card Board Shutter -->

The half insulating shutter -- light + insulation Details... 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.

Framed and un-framed thermal shutters made from Astrofoil... This is quite a nice design for thermal shutters made from Astrofoil. These shutters have reflective surfaces and both sides and provide a high R value.

The Astrofoil is stiff enough to fit into a window opening and support itself without a frame. All the details here...

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.

FlipFlic -- KickStarter project to automate control of thermal shades This innovative KickStarter project automates the opening or closing of slat type blinds based on time of day, room temperature, or light levels. It is simple to install, solar powered, and smartphone controlled. It looks like a simple way to save energy and eliminate the daily ritual of opening and closing the blinds a couple times each day.

Insulating Shutter Condensation Calculator,

Dave Window Condensation Calculator ... 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.

Air Infiltration Testing of Existing Double-Hung Window in an Existing Urban Historic, Commercial, Mid-Rise Building,

Logan Cravens http://www.portlandoregon.gov/bps/article/150881 I've always been a bit of a skeptic about the benefits of sealing windows -- I go through the motions of caulking and sealing, but unless the windows are really leaky how do you know you've accomplished anything? This paper makes me more of a believer that sealing can be well worth the time and effort. Fascinating paper describing in field work done to test for infiltration on existing windows in a Portland historic building.



The test shows the test apparatus, and the results for the baseline windows and the improvement for sealing (dramatic).



Its interesting that with some fairly simple sealing that very good leakage rates were attained (equivalent to new windows).

Window Shading

Window Shading Scheme -- from the Econogics site http://www.econogics.com/busys/shadecl.htm This is a pretty nice way to provide shading of windows on the outside (where it is most effective). The shade cloth is held in place with magnets and can easily be removed.

Heating Your Own Personal Space

Some times it just makes sense to heat your own immediate personal space -- this can save a lot of energy and result in increased comfort.

Kotatsu -- A Japanese personal heater http://en.wikipedia.org/wiki/Kotatsu Making a Kotatsu... The Kotatsu is a low table with a heat source mounted to the bottom surface of the table and aimed down.

You sit with legs under the table, and with a blanket or futon covering your lower body.

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 One maker of heated clothing...

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...

I Cut 87% Off of My Electric Heat Bill



Reducing heat use by 87% with personal space heating...



Video showing a live test of personal space heating...

This is a set of techniques that concentrate on keeping just your personal space warm while letting the room temperature drop much lower. For example, at the computer, a dog heating pad is used to heat the feet, a light bulb and reflector placed close is used as a radiant heater, and a heated keyboard and heated mouse are used. A total of about 80 watts is used to keep the person at the computer very comfortable.

The ideas in the section just above for sleeping also fall into this category. Do you have any good techniques you use to keep your personal space comfortable? 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. Most people can cut their household electricity use in half at a very low cost, and with a very fast payback ... Cutting electricity use of a typical US home in half saves: 6000 KWH a year

$600 a year in electric bills

6 tons of CO2 emissions 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 LEDs or 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, and for drying.

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 ...



Swimming Pools and Hot Tubs - If you have a swimming pool or hot tub, it will very likely be the top consummer of electricity for your house. Just the pool pump can consume thousands of KWH a year.

See the Solar Pool Heating page for ideas on how to make your pool or tub more efficient...

Phantom Loads -- Many electronic gadgets (TV's, entertainment centers, microwaves, chargers, ...) use power even when switched off. Electric coffee pots in "keep warm" mode use quite a bit of power just keeping the coffee up to temperature -- switch to a thermos type container to keep your coffee hot.

Here is how to kill these power vampires ...

This can save you several hundred KWH per year. Other (less well known) phantom loads ...

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 artcle 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 ...

Some Thoughts On Pilot Lights Some 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

http://www.homeenergy.org 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...

Converting a chest freezer into a very efficient refridgerator

Several approaches to converting chest freezers into efficient refrigerator: This article is from the Mt Best -- Australia solar house site: http://mtbest.net/chest_fridge.html A very interesting solar house with several unique features, and a bit more info on the chest fridge.

The thermostat shown on this page is reported to allow you to use a chest freezer as a refrigerator with large energy saving:

Beer Fridge Thermostat



And, a digital one:

http://www.micromatic.com This refrigerator, which is a converted chest type freezer uses only about 0.1 KWH per day (about 1/10th of good conventional fridges!). 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. One person reported using added thermal mass in the fridge on his off grid system to allow the inverter to be turned off at night.



Some comments on converting chest freezers to refrigerators....

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 and others. So, why can't GE do this? EnergyStar Fridge Ratings

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:

www.rparts.com/index.php?cPath=84_14 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 ...

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. September 2014: It appears that EPA is going to finally have an Energy Star program for dryers. Expect to see a lot of work on dryer design in the next few years to earn the Energy Star label.

Ken's Solar Clothes Drying Rack Full detailed pictures and plans for Ken's solar clothes drying rack ... When Ken could not find a good clothes drying rack at the local store, he set out to design and build his own. He came up with a great design, and provides detailed pictures and plans of the rack.



He includes plans for both a deck mounted rack, and for a ground mounted design.

One of the really neat features is that you can hang clothes on clothes hangers, and then hang the hangers right on the rack. All the materials for the rack are easy to come by and locally available.

A rundown on condensing dryers...



Energy stats for a number of condenser dryers... Condensing 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?

This will vary, depending on the size of the machine and the load. The condensing dryer saves an enormous amount of electrical energy by returning the already warm air to the drum, requiring only a few degrees bump in temperature, instead of heating room temperature air to the level needed to dry the clothes. Conventional dryers exhaust 200 cubic feet of air per minute from the residence, condensing dryers do not. This is 10,000 cubic feet per cycle that does not need to be heated or cooled to room temperature, an enormous saving in not only residential utility costs, but in the stress placed on the air intake systems of the building. " 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.





All the details on Randy's solar dryer conversion... Converting a Clothes Dryer to Use Solar Heated Attic Air 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.

Also, be very careful to check for moisture problems...

Clothes Dry Heat Recovery Using a Furnace Filter for Lint Removal... This is George Plhak's scheme for venting the dryer inside. It uses a box with an easily replaced furnace filter for the lint filtering. The furnace filter offers a lot of filter area, is inexpensive, and easy to replace. Be sure to read the SAFETY NOTE just above. All the details...

An Experimental DIY Clothes Dryer Heat Recovery Heat Exchanger... This is a prototype that I did for a heat exchanger that recovers heat from the dryer exhaust vent air stream. Its a cross flow heat exchanger made from twinwall polycarbonate glazing panels. There are 14 layers of twinwall glazing that carry the hot dryer vent air, while the room air passes through spaces between the twinwall panels. While I consider this experimental, it has performed well over a couple of seasons.

Phantom Loads

Phantom Loads radio interview on "Good Dirt Radio" Hear the interview ... This is an interview with yours truly that gives an overview of what phantom loads are, and what you can do about them. See the material in the item below for more details. The interview was one of many good stories and interviews from the "Good Dirt Radio". Thanks to Good Dirt producer Gary Lewin for his good work on this.

Using a Kill-A-Watt meter to find phantoms... Phantom Load suggestions from Marc ...

The worst of the Phantom Loads ...

(really gross offenders) Many electrical gadgets (TV's, microwaves, chargers, ...) continue to use power even after you turn them off. This can be just a little or a surprisingly large amount.



The sad truth is that over their lifetime, many electronic devices will consume more power during the times they are off than when on! This costs of billions of dollars a year and lots of green house gas. The four items listed to the left provide some ways to identify and eliminate these power sucking vampire loads.



It is difficult to take phantom loads into account when you buy new electrical devices because the manufacturers don't provide this information. One thing that would help is for all electrical devices to include typical and phantom power use on the outside of their packaging -- write to your legislator and suggest this! Until we get this, I would suggest testing new gadgets with your Kill-A-Watt meter when you get them home, and return anything that uses too much power when off (or on) -- make sure the store and the manufacturer know why you are returning it.

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).
