Going Green for $1,000 or Less

Dumping the Old Fridge is Greener than Installing Solar Panels

Let's face it. The greenest things you can do for your house and the planet fall a little short in the WOW Factor. Old refrigerators and freezers, and by that I mean almost any model from before 2000, are energy wasters compared to today's most efficient models. Dollar for dollar the best thing you can do for your house is to buy new refrigerators and freezers that use substantially less energy. Payback on a new machine can be as little as two years and most local utilities offer some sort of rebate or upgrade program to encourage their consumers to get a newer model. The government has some useful information about the Energy Star program

The second half of the green refrigeration solution is to make sure your old model gets recycled...and I don't mean the garage to keep your sodas cold, either. If you absolutely, positively want your sodas cold, buy a new refrigerator for the garage or rec room. Your old one, whether it's in the kitchen or the garage, is an energy pig. Modern recycling will safely remove the Freon or other refrigerant and send the steel off to to be made into something new and shiny. You can send it away knowing it will have a rich and worthwhile second life. Don't forget to keep your magnets.

bad flex duct connectionThe Joy of Attic Crawling

If the boring wisdom of getting a new refrigerator can't get your green gene fired up, how about a nice crawl through the attic or subfloor? It's very likely that as much as 20% of your heating and air conditioning dollar is being spent to heat and cool parts of your house you don't live in. Improperly sealed ducts, bad connections, and lack of insulation are major sources of wasted energy.

The good news is that I'm not going to ask you to crawl through scratchy fiberglass in your own attic. No, you get to hire a duct cleaning and repair specialist who can bring specialized equipment to clean and pressure test your system. Sadly, there's nothing glamorous left on your roof to show your neighbors you are Greener Than They Are. Maybe later.

Finally, the big bucks to show up the neighbors

Sorry. I feel like the Green Scrooge. You came for hot and sexy green-ness, and all I have for you is warm lime sherbet. I've already walked you through a new refrigerator and some duct repairs. Next on the cost efficiency list wouldn't normally be shiny new photovoltaics or a roof top wind turbine, but attic insulation, dual glazed windows, and weatherstripping instead. Still, it's my post and I'm going to skip that smart stuff and give you a chance to beat the neighbors to have the first photovoltaic installation on the block.

solar attic fan

For around $600 installed, you can have a simple, cost-effective, energy saving, building-preserving, roof-extending, moisture reducing solar attic fan. It's a great way to introduce yourself to solar energy, do your house a favor, and have a small touch of one-upmanship in your neighborhood. They work from morning until night all year around helping to keep your attic air circulating. It will help keep your house cooler in the summer and help prevent moisture accumulation in the winter.

Three Green Cool Suggestions

These three green ideas aren't as HOT as some newer comprehensive strategies for sustainability. What they have in common is modest price tags that the average home owner can fit into their long term green budget. Each of them can be accomplished for under $1,000 and typically in one day. Going green can be fast, affordable, and create great long term savings. In my book, that's sexy enough.

Esko, the climate in Las Vegas is perfect for the solar attic fan. I don't know if you saw the latest Scientific American article about solar energy, but the authors are calling for thousand of square miles of Nevada, Arizona and California to produce all the energy for the United States by use of solar by the year 2100. You definitely have the sunshine for it.

Dave,

 

Good tips. It really is about saving green and going green! Forget all those expensive fancy-schmancy improvements... If you can do it on the cheap, then do it on the cheap because in the end, you are probably saving resources as well as money and THAT is what green is all about.

Alex, you hit the nail on the head. If you can do things on the cheap, maybe you can do three or four good things instead of just one.

Attic fans really do work great. Anybody who's in a climate like Texas or South Carolina will notice a difference.

Chip,

Because these are self-contained (no electrical hookup needed), the natural choice to install one is probably a roofer.

I don't know if anyone has noticed, but I saw these on sale at Costco for under $400 a few days ago.

Heres a question

would it do better than the 10 or more regular square vents you could get for that price, that work 24\7 and dont have moving parts that WILL eventually fail??Sorry but I am a new construction analyst, and if you figure cost/savings in the long run, standard metal roof vents spread properly offer better coverage against trapped air and has a better cost/savings ratio due to the lifespan of your vent. You can add radiant barrier for the cost of 2 of those fans. Bring you insulation to r-42+  for the same depending....

somebody needs to mention the fact  whole house fans in the ceiling waste much more than they could ever save!!!! They leak air 24/7 365, have no r-value compared to the average required r-38.  Do you know how many portable or ceiling fans you can run with 400watts! Sealing your house is so cheap and so important, start by getting rid of your big loud eyesoar wholehouse fan. I wish i could show you some of my thermal pictures, those fans are bad news. Put them in your garage ceiling or recycle them.

Here and also:

Thanks for your comments.  I stand by my original post, but I welcome your thoughtful and well informed comments. Let me address some of our areas of agreement.

1. I agree that moving parts will fail.

2. I agree that un-insulated whole house fans make a huge gap in the insulation barrier the house needs.

3. I agree that super-insulation (R-42 and up) can be useful.

As to where we disagree:

1. Ten square vents or any traditional venting (not commercial style roof vents) don't do the job. Sorry, but unless you go with continuous eave and continuous ridge vents combined, your attic is going to get hot.

2. You don't mention it, so I will. Moisture build up in attic spaces can be a major problem in many climates. The cost of replacing an entire roof deck because of mildew or rotted sheathing far outweights the cost of making sure ventilation is effective. Your new construction analysis has to include the potential for catastrophic failure of the roof membrane if moisture isn't addressed properly.

3. Radiant barriers are occasionally effective in uninsulated commercial spaces, but they are not the right solution for residential construction.

4. Whole house fans don't work in every climate. If your area doesn't cool off at night, a whole house fan doesn't provide much relief. In areas with hot days and cool nights a whole house fan is the preferred solution for cooling when compared to air conditioning. You talk about portable or ceiling fans and they do nothing to address the main source of heat build up in the house; the hot attic. Whole house fans directly cool that hot space. Can they be loud? yes. Can they be a heat lead if uninsulated? Certainly.

I think if push came to shove we would agree that homebuilders should:

1. Insulate at least to R-38

2. Use great vapor barriers to keep moisture out of the attic.

3. Use some highly effective method of air circulation in the attic. Whther a solar attic fan, mechanical vents, or large passive vents isn't my biggest concern. Making sure air circulates winter and summer alike is my concern.

Thanks for disagreeing with me. I love a good discussion with somebody who knows what they are talking about.

The solar attic fan seems to be the most popular solution for all of us hot heads. It is on my list after the solar hot water heater (my current lustful fantasy).

Hello Dave,

Here is some more feedback on the attic venting-

Our company installs Attic Fans and Whole House Fans Nation Wide mostly for Property Management Companies, Homeowner Associations and Apartment building complexes.

This is the general rule of thumb that works very well regarding roof venting.

1. Take the total square footage of the attic then divide it by 300 that will put you in the ball park of the venting required for that attic space. IE: 2500 SQFT attic space / 300 = 8.3 square feet of free air venting. Some contractors like to split the intake and the out take with a 50/50 ratio-

We have found that while the 50/50 ratio works well-- the 60% on the intake and 40% on the out take works better for our applications. Also-- Always make sure that the intake vents are not blocked with insulation or any other obstruction. This will decrease the performance of the fan and could limit the life expectency of the fans motor.

Here is some feedback on the solar attic fans-We started installing solar powered attic fans about 15 years ago and to be honest the fans  just could not compare to the standard line powered version attic fan.

However today the New Solar Fans are MUCH better- And now that the Federal Government is offering a 30% tax credit on select fans to INCLUDE a 30%  tax credit on the installation of these fans........... its is a good time to invest in one. 

Here is a link to an on line  Whole House fan Calculator That is helpful.

Here is a link to an online calculator that will help you figure out how much free air venting your attic currently has.  Square Vent Round Vent Calculator.

And finally here is a link to the company that will be more than happy to answer any questions regarding attic fans, whole house fans or attic venting !

Thanks,

Also-

In response to the new construction analyst post about whole house fans-

Whole house fans cost pennies to operate when compared to air conditioning. A building owner could save as much as 90% off air their conditioning bill. This is not sales hype this is real world...

We have installed and sold almost every brand and type of whole house fan imaginable ( thousands of these fans over the years ) Why ? Because they work !

Nobody wants an airtight house or to live in a vacume-( With or with out a whole house fan ) Especially when some one in the house is ill-

And... Most new style whole house fans ( Won't mention any brands ) are So quiet you can whisper to a person directly under the fan and have them hear you perfectly-

With regard to the thermal photos-   We too have shot thermal photos of the OLD STYLE BOX FANS and AGREE they are a thermal nightmare- In warmer climets its  a non issue. In colder climets we install a magnetic thermal cover on the fan and it make a 90% difference.

The new style whole house fans have been re engineered and have addressed the above mentioned issues in my opinion very well.

Final comment- When the outside temp is high and the sun is beating down on your roof,  the  "trapped" super heated air that is in your attic can not escape at a fast enough rate- it then presses through your ceiling, into your living space.  And you think that portable fans or ceiling fans are going to remove the hot air ? In our experience we have learned that this will only circulate the hot air that is trapped in the living space. You have to remove the hot air !

A number of H.O.A.s that we have worked for will not allow any penetrations( holes on the roof. ) 

So the person that lives on the second or top floor of a building can not install an attic fan to remove this super hated air.

However when we install a Whole house fan into their individuals  unit it becomes a win win.

No holes on the roof, No more trapped super heated air. more comfort.

Ask any one you know that lives on the top floor of a condo/townhouse or apartment building if in the summertime when it is hot out if their ceiling fans are effective at removing the hot air-

Whole House Fans and Attic Fans Work.......period.  :)
