Not only will you save energy...

apparently you can also contribute to a more tightly knit, liveable and sustainable community. This is an interesting read.

Small fridges make good cities, but American fridges just keep getting bigger

Reminds me of something I saw years ago on "The Nature of Things". It was a special about green homes and building techniques. There was one home that looked like a series of underground onions, but where the shoots should be there was a round skylight to let light in, with the onion rooms connected by tunnels. They were all connected by tunnels, and they were naturally heated and cooled largely by the earth that surrounded them.
The coolest part (no pun intended) was the fridge that the designer had made. He recognized that a big flaw with the fridge design that we all see in our homes is that they open vertically, so that all the cool air (which is more dense fluid and sinks) pours out when the fridge is opened. That's why I get so frustrated when I see "new energy efficient" fridges that have a bottom freezer with a drawer instead of a door. Especially when that drawer is not solid but is a wire basket. Not only is the cold air going to flow out, but the food is all moved out into warm air without even a solid barrier to isolate it form the warmth of the kitchen. Any air cooled by the food will fall onto the floor as well, instead of back into the freezer.
Anyway, back to the well designed fridge. It was circular, with a pneumatic lift in the center. When you wanted to grab the ketchup or whatever you needed, the button is pressed and the food lifts out on wire shelves (admittedly exposing all the food to warmth) BUT the cool air is left within the fridge itself so that an entirely new mass of air does not need to be cooled. WHAT SAVINGS!

Think of the air in your fridge as cold water. You open the door, and it pours out all over your kitchen. But if you're at the cottage and you grab a beer out of the kiddy pool full of ice, you don't have to let all the water out. You just grab what you want and leave the cool fluid behind.
Heavenly!

Food for thought.

An excellent interview with an outside-the-box thinker, Michael Reynolds.

"The utilities are bad because they mine the earth for fuels and make nuclear power plants, but just as bad as that are the infrastructure that they use to deliver the utilities. And then they are all run by corporations and so on, so the people are vulnerable.
This building, the people that live here are not vulnerable, they are a free people to exist no matter what happens to the economy or anything." (emphasis is mine)

While not everyone has the means, opportunity or drive to embrace such a radical home, everyone can surely see the value in reducing their vulnerabilities to the energy market and the geopolitics that drive it, whether they choose to live on the grid or off.

More on loading order and investing in your greatest investment

There are a couple of reasons why I went the route that I went when I became interested in Green building and sustainable design.
In 2008, when everybody became very interested in energy issues, my father was dying and I was immersing myself in a lot of new information. My father had always been the provider in my family, not just for our immediate family, but always helping out in the community and our larger family as well.
When he became sick, I saw that there was going to be a large gap. Where he had money to help people out, I quickly realized that that was not going to be an option for me. I had just returned from teaching abroad, and I was faced with poor job prospects. Plus, I was delving into the world energy situation, and this was a particular topic of independent study that at one point kept me at varying levels of insomnia (stress+massive interest) for almost six weeks. Needless to say, I was not a lot of fun at parties. I started looking at ways to save money, and ways to help others save money as my niche to fill the gap.
In 2009, I had the opportunity to return to school, and went to Prince Edward Island to Holland College, and began studying "Electromechanical Technology". I had the idea that I was going to learn all about electrical systems (plus some millwright work) and be well positioned to help out changing the country over to renewable power generation and clean energy with solar panels and windmills. Midway through the year, I revisited the documentary "Garbage Warrior", which documented the ups and downs of "Biotect" Michael Reynolds struggles to build sustainable homes largely out of recycled materials while still conforming to the demands of conventional building practices. Not an easy task...
I realized that solar panels and windmills are really window dressing. They are bandaids that are often applied to the sieves that we call houses, and very expensive ones at that. I started reading more, and realized that in most cases, low tech and low cost fixes make the biggest differences, and that once those differences are made the bandaids will really make a difference. Solar panels and windmills are a great step, but seeing the holes that existed in conventionally built homes is why I switched into Construction Technology.
While staying and studying at Sirius Ecovillage in Massachusetts, we had an afternoon with a local business person from the community there who was a Building Performance Institute certified Building Analyst. We toured several houses that he had worked to improve, and learned about the protocols used to properly order the work to maximize payback. What I liked about the ordering was that the work was ordered to fit the customer's budget, working with them to reduce one bill, pay back the initial work, then allow for savings for larger items. I was so impressed that when I was finished my college program I returned to Massachusetts to get the training through BPI myself.
What are the first steps? As I said before, you start with insulation and air-sealing, ensuring proper ventilation and air supply, and then move on to the more expensive items. 




So why is the order so important?

Starting with insulation and air sealing will immediately reduce bills. I have been in several homes that I have helped with their attic insulation, and they noted almost immediate improvement in comfort. When we increased the attic insulation at my family's cottage, we noticed the next day that the air conditioner turned off once it reached temperature. It was significant, because it had never turned off before. It ran constantly.
Your attic alone, when properly insulated to R-50 or R-60 (adding R-30) and paired with air-sealing, can cut up to 25% off your total energy bills. This means less running your furnace, less running of fans, and less cycling on and off once temperature is reached.
Holding the heat in will not just save you on your bills in the present, it will save you on maintenance and replacement costs on your major comfort appliances.
Taking that 25% you saved means that attic insulation will often pay for itself in as little as three to five years, depending on the size of your attic and the conditions before work is done, as well as the quality of your air sealing.
Three to five years to pay back means it is an investment that pays 20-33% back. This beats just about any investment that you can come up with in the market. The big difference is that you are getting money into your pocket each year by not paying it to utilities. And unlike monetary investments that fight inflation (how much of your gains are eaten by inflation each year?), the nominal value of your savings will increase every time inflation drives prices up.
This means that as the price of fuel or energy goes up, SO DO YOUR SAVINGS!
If energy prices stay the same, you still pull in the same savings as you would today.
Even if energy prices go down, you will not only pay less along with your neighbours, you will continue to save more on what you do pay.

I really believe that for anyone who is looking to save money, live better, increase their free time, and to do it in a smart way, the BPI series is a great place to start.

More to come on active versus passive approaches.

Pants first, then your shoes

There is one common mistake made by people when they begin home improvements to reduce their energy consumption. The problem is that many of the things that should be done first are not only ignored because home owners can't see them, but aren't commonly sold because they tend to be the lower cost items that salesmen are loathe to push.
As one of my instructors once brilliantly put it:

Insulation ain't sexy.

What items are sexy? Think curb appeal, or good dinner party conversation.

"Wow, are those solar panels?"

"I just picked up a new DC furnace."

"All new windows... it was getting to be time."

 Almost everyone I meet assumes I am there to sell them windows. While windows are definitely sometimes needed, they are almost never top of my list. Most heat loss for windows occurs around the window, not through the window. Replacing a window before sealing it properly might cost you much more than it will save, even in the long run.
Perhaps you have a brand new high efficiency furnace. I can't say anything bad about that, because efficiency is always a step in the right direction. However, replacing a furnace before pursuing air-sealing and insulation will only ensure that you are very efficiently producing heat that will still be lost at the same rate.
Taking care of insulation and air-sealing issues will make sure that when you do replace higher cost items, you will receive the greatest possible savings. You may even be able to get your house running efficiently enough that you can downsize your appliances, rather than use HE savings to balance your bigger, more powerful furnace.

Think of it as putting little heat pads in your mittens, only to realize that you have wandered out without a coat. You really need a good outer shell before you go pouring heat into it!

Stay well.
