New Job, maybe a few new posts too.

A return to work and a return to blogging

After two years of retraining in the Renewable Energy/Energy Efficiency program at Greenfield Community College, which I cannot recommend to highly, I've begun work as an Energy Auditor for Next Step Living Inc. I and two others will be heading up their operations in Western Massachusetts.

Next Step Living is participating in a pilot project to open up the state-wide Mass Save homeowner retrofit project to independent contractors to perform audits in addition to weatherization work.

Generally, I have had trouble keeping up this blog while I was busy, but I will try to update this with the beginning of my new job.

I'm currently finishing up training in Boston to begin Audits in Greenfield starting next week. I'll keep you dear reader posted throughout the process.

Unfortunately this new job requires a new car

That's right, Katie and I who have spent the last six years with from zero to one cars, now need a second vehicle, and the wonderful two door Honda Civic of hers that gets 40 MPG just won't cut it for carrying the tools of my trade. So we researched to find the most fuel efficient cargo carrier that we could. It became clear that rather than buying an older pickup which would mean that we would end up replacing two cars in the next few years, it made sense to find a newer and capacious hatchback.

The cute, fuel sipping Ford Fiesta, and Toyota Yaris failed for their miserly cargo room. We found that There were really three competitors for what we wanted The new Kia Rio 5, the Nissan Versa Hatchback, And the Honda Fit. We decided against the Rio 5 because we just had a Rio four-door sedan rental that failed to wow while we visited my family in Arizona and as a new model we knew that it was unlikely that we could get any real deals. We test drove both the Nissan Versa, and the Honda Fit. Both have manual transmission options that are quite peppy (the Versa automatic was sluggish) Both are fairly well appointed at around $15,000 MSRP and the Versa can be had for much lower than that. For most people, I could see both being suitable, but for me it came down to the superbly designed and engineered cargo space of the Honda Fit. This thing is a wonder to behold. The rear seats fold flat and level which makes the space much more usable. In my day to day usage, I will rarely be returning these seats to their upright and locked positions. This vehicle will act like a mini-pickup for me, that happens to have access on three sides.

Blower door and combustion safety at home

This weekend I will be testing my skills on our new home - Oh you didn't know that we had a new home? that's because I haven't posted to this blog since we began searching for a new house. It's pretty nice. I'll dish more later.

Today is Representative Town Meeting in Brattleboro. Katie is an elected representative, and she's already hard at work hammering out the details of this year's budget.

I also wrote an article for the Brattleboro Reformer as a member of the town's Solid Waste Committee. It's about composting, and includes information I haven't posted here. Check it out.

Compostin around Brattleboro

Sustainability should be the true goal of our community -- it's good for our neighbors, ourselves and the environment. Our Vermont lifestyle should not have products shipped here from thousands of miles away, just to be used for a short time and sent away in dumpsters to remain in the landfill forever. We should strive toward zero waste.

Step one is easy: compost. Rotten fruit, vegetables, paper towels, leftover meals, what do they have in common? They're organic waste, and half of our trash in Brattleboro. That's a lot that could be composted.

In Brattleboro, many people already compost or think about composting. Before you start taking all your leftovers into the backyard, you need a plan -- not all organic waste is easily or safely composted in your compost pile. With a little effort just about all of it can be kept out of the garbage.

Some people compost religiously, but would like to be able to dispose of things like meat which attracts animals, dairy and oils which are hard for the micro-organisms to break down, animal wastes which can carry pathogens, or weeds which have seeds that can be spread in compost. Some people would like to compost, but feel it is too difficult or they don't have the required space.

When most people think of composting, they think of a heap or bin in someone's backyard. Kitchen scraps and yard waste are put in a pile, and nature slowly turns it from trash into very fertile

dark brown dirt known as humus. This can be put in with potted plants and used along with soil as a nutritional supplement instead of petrochemical-based fertilizers saving precious oil from a job done as well by a natural product.

It can also just be left where it forms if you don't grow plants and don't have any friends who want your compost. This type of composting can only take fruit, vegetables, egg shells, yard clippings, leaves and non-bleached paper because it's a low temperature process. It's easy so many people do it. The pile needs a specific ratio of green material to brown material in the pile- most people just manage this themselves by putting on more yard clippings or food depending on how the pile is developing.

The compost heap can be improved with a bin. A bin speeds up the composting process and can kill weed seeds and germs if it's hot enough. Still you are limited to what you can compost. Every Spring, WSWMD has compost bins available at a discount. Check out the Web site www.windhamsolidwaste.org for details.

You can also make your own bin. I live in an apartment house with three total units, and I made a compost bin from a large plastic garbage can with many 1/4-inch holes drilled into it. We all use the compost bin. It works slower in the winter, but we don't run out of room.

At home, there are two advanced forms of composting: vermicompost and bokashi. Both can be practiced indoors with very little odor in a small space. Vermicompost is composting with a specific type of worm. Worms actually eat the organic matter, and leave very nutritionally rich castings. The worms work fast, but they should be kept inside because they are not native to Vermont. You can put more types of scraps into vermicompost than into a compost heap, but you must care for it like you might care for a potted plant. It's not as much responsibility as a pet, but it still requires some nurturing.

Bokashi is the only form of composting that uses fermentation instead of aerobic decomposition. It's like making beer for your plants. Bokashi is a japanese technique that allows you to turn any kitchen scraps into nutritious plant food. This can be meat and bones, citrus, eggshells, yogurt and even milk. To make bokashi, you need a bucket with a drain or spigot on the bottom, bokashi mix (which contains the microbes that break down the food) and your kitchen scraps.

Brattleboro has a large renter population, and sharing a compost bin may not work for everyone. Even one person interested in composting and willing to manage it a little can make a difference to all our neighbors.

If you are interested in putting together a community composting project, please contact the Solid Waste Committee at brattleborosolidwaste@gmail.com, and we will try to help.

I've gotta thank Katie for all her help editing it. I just wasn't feeling my regular pithy self. Working for a word count takes away some freedom.

Freezing Rain and Melting Ice

My front steps after I shoveled

Today is a pretty miserable day to be outside. It started out snowing and quickly moved to freezing rain. We were running out of ice melt at my apartment and I wanted to go and get some more. We have treacherous stairs and a driveway in the best conditions, getting in and out in this weather is very tough. Of course I didn't know what the least environmentally disastrous type of ice treatment was. I went with Calcium Chloride (CaCl2) because it claimed to work at the lowest temperatures.

When I got home I did a little research. I'm satisfied with my purchase. CaCl2 is pound for pound worse for the environment than regular salt (NaCl), but it is far more effective, you don't have to use as much. However, you might have to reapply it. The most important environmental concern is proper use and application of whatever you use. Use only as much as you need to, and center it on the surface you are deicing. As it melts it will spread. If it has snowed and starts to freezing rain, you are better off waiting to shovel so that the snow acts like a buffer from the freezing rain and a hard shell of ice forms on top of the snow instead of on the sidewalk. And always remember to shovel before you apply any ice melter. You don't need to melt snow, just move it.

If you can find it, Calcium Magnesium Acetate (CMA) is the environmentally friendly solutiotion, but it costs thirty times as much as salt in bulk. You can often find it blended with CaCl2 or NaCl which is a good choice. If it has at least 20% CMA, then corrosion can be greatly reduced.

Pay As You Throw, Fiscally Conservative & Socially Progressive

CC image on Flickr by Bill Ward

Tonight the Brattleboro Selectboard is likely to reverse a previous decision which rejected Pay As You Throw (PAYT) garbage pickup. Brattleboro, like many towns, doesn't charge you directly to pick up and haul garbage. Instead garbage collection and pickup is part of the town's general budget and is therefore payed by property owners based on their property taxes.

It's an unfair system. I have no reason not to throw out large amounts of garbage every week. I have no reason to recycle. And anyone who does limit their trash and recycles what they can is actually paying more so that I can do whatever I want. PAYT makes the system fair. If I want to be wasteful, I still can. But now I will have to shoulder the cost of the waste myself. People have controll over their expenses.

A likely scenario for PAYT in Brattleboro will be that every 30 gallon trash bag you throw out will cost $2. Over the course of a year, if you throw out one bag a week (which I average) it will cost you only $104. If on the other hand, you have no interest in sorting your recycling out, composting, or reducing your waste, you will pay significantly more. I will not have to support your bad habits when my landlord would raise my rent because his property taxes increase.

The great things about PAYT are that you the consumer are in control of your expenses, you do not have to subsidize other people's wastefulness, and it encourages everyone to conserve, recycle, and compost.

A Culture of Poverty

Barack Obama wants to build a clean energy future and he's got his work cut out for him. We the people of the United States are a very shortsighted group. The idea of paying more now to save more later is anathema to most. His energy policy plans are a good start, but we need to be sure that national policies have local backup.

Focusing on the consumers, he plans to weatherize one million low income homes a year for the next decade. That's ten million homes in ten years. According to the U.S. Census Bureau, there are more than 80 Million houses in the United States and a total of more than 128 million units. Weatherizing ten million homes is a significant step towards energy efficiency, but it only hints at what needs to be done.

Currently money is being spent primarilly to support the energy costs of low income users. A cynical but technically correct translation is that every american supports the energy utilities so that they allow the poorer of us not to freeze.

We need to commit to efficiency on a grand scale rather than just paying off debt and defraying costs. The LIHEAP heating assistance program has received a much deserved budget increase for 2009, bringing funding up to $5.1 billion for the year. For Every dollar spent in this way we must spend another dollar to actually fix the heating situation. Every new home should be required to meet current Energy Star standards (or at least all homes in developments of x houses or more) and new energy star standards need to be set close to zero net energy.

Armory Park Del Sol's rooftops

While I was in Tucson in december I came across Armory Park Del Sol, which is an excellent example of what every new development should be. It is downtown Tucson infill. The lot was undeveloped and probably planned originally for warehouses, now it is residences in a style similar to the historic neighborhood it borders. Of course they actually have high tech offerings as well:

All Armory Park del Sol homes are now built with a solar electric system of at least 1.5 kWh (earlier homes were built with a 1 kWh solar electric system) and a passive solar water heater that meets approximately half of a family's water heating needs. The Net ZEH has a 4.2 kW solar electric system and an active solar hot water system that is designed to provide almost all of a family's water and home heating needs.

I applaud President Elect Obama on his energy plans, but we need more projects like Armory Park Del Sol and Efficiency Vermont. And I think that we need some very well crafted regulation to encourage it.

Happy New Year 2009

This last year brought a lot of progress for the green movement. Green has entered mainstream American thought. It's been at least fifteen years since people have thought about their impact on the planet and the environment so much. Americans elected a new president who actually plans to address environmental issues and stop the systematic dismantling of policies which have protected both humans and habitat for many years.

While the economy is generally in a tailspin, green sections of the economy are still expanding. Gas prices went above four dollars a gallon and for a short time more people bought cars than SUVs. The big three automakers are still unwilling to change their methods enough to really make a difference in how cars are made, marketed, and sold. Toyota also had its first operating loss in 70 years, but they are still making sound investments and actually turned a profit when everything in their business is calculated.

For New Year's Eve Katie and I went to a party at a farm that is now being rented by a number of twenty-somethings who are working the land there. They have a cow which they share, some sheep and planted garlic this fall. We hardly knew anyone there, but they all live around here many making some living off the land.

This year will hopefully bring real progress in both the world and people's minds. We are at the point where humans can probably continue to exist as a significant species, but If we really want to stick around without losing everything we know and love in the process now is the time to act.

Compost Post

No, this isn't about the food you eat. It's about the food you don't eat. In the developed world, 40%-50% of the trash sent to the landfill is organic matter. Food, paper towells, etc. Organic matter is capable of decomposing very quickly and returning it's component elements back to the earth for reuse, but this doesn't happen in a landfill. It can happen in a compost heap though. If we really want to lessen our impact on the Earth, we have to compost everything that we can.

Some of us live in apartments in big cramped cities, and for us it' really hard to make our own compost heaps. In some cities across the country, the government has stepped in to provide compost pick up, along with the ubiquitous trash and recycling pick ups. New York City did a pilot program for this in the Nineties, and decided it was not worth their while.

The overall conclusion reached from the various collection pilots is that while in certain cases it may be possible to collect source-separated food waste, collection route efficiency is very low and would be both expensive and impractical to implement on a significant scale. The studies of on-site systems conducted by DSNY and other parties demonstrated that these technologies remain cumbersome to operate, do not effectively control odors, and are therefore unsuitable for widespread use particularly in a dense urban setting.

Other cities such as San Francisco, have had very successful programs for years. While most large cities will probably move to municipal composting soon, it's hard for smaller towns to do the same sort of industrial composting as is done on the large scale for the municipal compost projects. If you live in an apartment,ask your landlord if it's okay to put a compost bin somewhere on the property and then tell all the other tenants about your compost bin. Katie and I have a surprisingly good compost bin going, after only about a month of use because six people are contributing to it.

Kill a What? At the Library?

Kill A Watt on the shelf: Photo by Katie

I don't know about you, but I love the library. Mine is a very good one. In Williamsburg, I got fed up with it's branch of the Brooklyn Public Library which was only open till seven one day of the week. It had a decent selection of comic books, but every other section in the library was lacking. I haven't visited it in two years. But the Brooks Memorial Library is open till nine three nights a week. It has a variety of new and old books, magazines, CDs, VHS casettes, DVDs, and one more thing: a Kill A Watt.

Kill A Watt is a brand of electricity usage monitor. You can buy various electricity usage monitors for anywhere from $25 to $100. They have different bells and whistles, but you really don't need to use them very often. You take the Kill A Watt, plug it into the wall, and then plug your 120v appliances into them for a day or more. The Kill A Watt measures how much electricity runs through it and how much time has elapsed. You can use this to find phantom loads (the electricity used by things that are turned off) as well as to find out how much electricity it takes to do something like watch your favorite television show. It can help you remember to unplug appliances that are wasting energy.

Kill A Watt in its box: Photo by Katie

But I'm done with it, I've had it for two weeks and I don't need it any more. So it's fantastic that I don't own it and can just return it to the library. Someone else can use the same Kill A Watt that I've been using, and I don't have to know them or give it to them. This is part of a state-wide program from the Sustainable Energy Resource Group and they should be available in many Vermont libraries. But if you're not in Vermont, many other libraries have them available too. If your library doesn't, ask for them to get one.

Eating Locally Goes Global

Locavores are the rise, and more than that fringe are the people who try and get an increasing amount of their foods from local sources. The ideas involved include knowing where your food came from, and supporting local food production, which usually means lower environmental costs.

There is a common theme of locavore challenges come harvest season now. Here in Brattleboro, we have the Windham Localvores Local Food Week which starts on september 13th, and the internet based Eat Local Challenge in october.

But things can't be as simple as just eat locally. What if your neighborhood is home to one of the biggest pork processors in the country? And most of the farms around the area are factory farms? At least the food doesn't have to travel as far to the supermarket. The News & Observer of North Carolina had a couple of articles this summer which followed the life and death of a pig that was exceptional. The N&O pig was raised on a small farm in the heart of big pork country. He was a heritage animal, and a product of natural breeding. He lived a little longer than his neighbors on other farms, got to do "pig things", and then went to slaughter at another small operation.

Watch both the audio slide shows.
Ossabaw Hogs, Naturally Raised
Ossabaw Hogs, Farm to Market

And here are the articles that went with them:
Rooting for Locavores
Gone to Market

Katie and I try to eat locally, naturally, frugally, and flavorfully. So far there is no rubric that combines these values and gives an absolute output. We have to just live our lives, and try our best tobe satisfied with the outcome.

Thanks to Varmint Bites for informing me of the articles.

LIve Green (rhymes with five bean)

Saturday Katie and I went to Live Green in Manchester, VT. It's a green lifestyle showcase and concert. Katie was there for her new job at Marlboro College Graduate Center's MBA in managing for sustainability, and I was there to help out and see the booths. The event was very well attended. They expected 400 people to show up, and more than 1,000 had arrived by 1:00.

Katie's booth was right next to the CVPS Cow Power booth. From our neighbor, we learned that 60% of our electrical needs could be provided by one dairy cow. We are not heavy electrical consumers, but there are certainly a lot of cows in America ready to help us with energy independence.

I also ran into Bill Hulstrunk, one of the teachers of the super-insulation course that I took at Yestermorrow this winter. In October, a friend and I are going to take a course on biofuels there.

While looking for pictures I came across this great set about industrial digesters.

Book Review: Bringing Nature Home

For some reason, I wrote this review in May, and thought that I'd posted it. The book Bringing Nature Home is the most influential book I've read this year, and I am very disappointed that I have not shared my views with all of you sooner.

Bringing Nature Home by Douglas Tallamy is several books in one. It's a manifesto, a guidebook, and a catalog of native species to use for landscaping and gardening. Tallamy begins by explaining why native plants support a greater amount of life than non-native ones. Non-native plants have different chemical compositions than native ones that are even closely related to them. This is a big issue for insects. Studies that he and others have done show that the numbers and types of insect feeding off of non-native plants are always significantly less than natives. These insects are the basis of converting much of the energy of the sun's rays into something that can be digested by larger animals. The replacement of or native forests and grasslands with manicured lawns and imported plants has our continent on the brink of catastrophe. The loss of habitat and food means that eventually many species will go extinct, and if a large insect extinction happens, it will be followed by a die-off of songbirds and small mammals, which will be followed by starvation and disease of larger animals, you can then imagine all the forest creatures that survive coming into the suburbs and cities and getting hit by cars in their search for food. One can only hope that would be the worst of it, but it might not.

This problem becomes nearly intractable when you realize how well non-natives can do when they are taken out of their natural environment. Plants that are outside of their home environment lose some of the pests they had before, sometimes they also bring along ones that they are already accustomed to, but their relatives are not. This makes them able to put more energy into growing and reproducing. Sometimes they have adaptations that make them invasive, such as a huge number of seeds, or fast thick growth that crowds out other plants.

Tallamy's solution is grassroots and simple: plant native, plant more in volume and kind. He makes the reader's job easier by creating lists region by region of native plants that can be used instead of their non-native counterparts. If one person changes their planting and landscaping habits, then a little bit of not-necessarilly natural, but livable environment comes back. If their neighbors do it, the increased size of the habitat can support species in that area. If we all do it across the continent, we can reverse the threat that all of our landscaping and highways and buildings pose on the environment and eventually on us.

The Road Home

I've moved out of Brooklyn, to the beautiful rolling hills of Southern Vermont. Hikes up green mountains, riverside bike trips, and strolls downtown are all available to me. Walkscore gives my apartment a 92 out of 100. But the coop which is two blocks away isn't listed, and a restaurant in nearby Wilmington is supposedly just a couple of blocks away, I submitted changes for both of those items in Google Maps for good measure. Katie and I are both happy with the new lifestyle.

Next week I will start a certificate program in Renewable Energy/Energy Efficiency at Greenfield Community College. The program should give me a hand in transitioning my career to one of green renovation and rehabilitation. A lot of people seem to be coming around because of high fuel prices, but some people are thinking deeper about it. Earlier this week Katie and I went to see Tom Silva and Kevin O'Connor from This Old House at the ReStore in Springfield. The house that they were finishing up was actually a new house, but the owners had Tom and the crew of the ReStore dismantle the previous house after they could not find anyone to give the house away to. The remains were given to Habitat for Humanity and the ReStore and 90% of the teardown was diverted from a landfill.

Construction is a much bigger consumer of energy than normal home heating, but the costs are hidden in the prices of goods. So even though the house that they built on This Old House, wasn't technically old, the building philosophy is similar to renovating an old house.

Quick Bites: Thursday, May 22nd

This weekend, Katie and I went on the Putney Solar & Green Energy Home Tour. We visited an incredible owner built home on Putney Mountain that Katie said was "inspirational." It had a home made solar array supplying only 600 watts to the battery bank, but it was no small house. Everything was well thought out from the siting to the appliances: the fridge was gas, the stove which also supplied the hot water was wood, and they had a masonry stove for heating during the winter. They even had a washer and dryer.

Like pollinators, but don't want to keep honeybees? Why not get a native bee nesting block?

Or perhaps bats are more your style. Most bats in the U.S. are insectivores so keeping bats around is a great way to keep your garden healthy. Sadly bats in the Northeast have succumbed to an illness (currently called white nose syndrome) that uses up their fat stores for hibernation this winter. The bat houses that you can make or buy may not be occupied year round, because many species of bats are migratory, but they can hold hundreds at a time when they are occupied.

If you're thinking of replacing your consumer electronics (i.e. iPods, cell phones, etc) you might be interested in the CExchange. They help you appriase your product, then you mail it to them where they refurbish or recycle it, and send you money. Like Craigslist or eBay without the hassle.

My mom has been happily using a Sun Oven instead of her own indoor stove for the last couple of months and she swears that she'll write a review for me soon. But to tide myself over I found this review of solar ovens by Cooks Illustrated. It turns out that you can even use them as far north as Boston.

Oh Green Consumer, Where Art Thou?

My Glidden Collection

I am a collector. I particularly love collecting tableware. China, glasses, silverware, it's all so wonderful. But I've run out of space and I have everything I need. Katie and I have a full service for 16 even though we only have room enough for four in our cabinet or at our table. When we move, that will change of course. We also have Fabulous menagerie desert plates by Glidden, a company from Alfred, NY in the 1950s. I have a set of eleven red with white polka dot Fitz and Floyd dinner plates with a variety of cups, saucers and accessories to match. And I have a tea service for four. But the desire to find new and exciting vintage tableware and kitchen goods continues.

Fitz and Floyd dots

I hope that my desire can be helpful to some of you. Collecting and using vintage ceramics is great for the environment. Ceramics have a high embodied energy, which means that a lot more energy is used to produce a ceramic plate than a paper or plastic plate. To make them a truly environmentally sensitive option ceramics have to be used over and over again. Except for some glazes or decorations, ceramics are usually chemically inert. All the harm that they caused to the environment was just in making them unlike in plastics where production is just the beginning of the trouble it causes.

My favorite china from childhood

So here's the deal: I want to connect you to the vintage tableware of your dreams. I've categorized a lot of great dinnerware from formal to casual, from rare to common, from cheap to expensive . I hope that I can help those of you that want and need dinnerware to select and acquire vintage pieces or a collection that you feel both fits you better than any other dinnerware and eliminates the waste of excess production. I'll help you find what you didn't even know existed and then I'll help you collect it. With so much wonderful design already in the world, everyone deserves to have tableware that makes them happy to eat off it. The fact that it can be had without manufacturing anything new is truly great.

Georges Briard's Fancy Free tea service

As I was researching this project, I actually fell off the wagon myself and bought a wonderful tea set by my new favorite mid-century designer Georges Briard. Please help me help you to some other excellent tableware, flatware, glasses, and cookware before I have to help myself to it.

People are receiving their rebates from the IRS now. If you chose to receive your refund through direct deposit, you will be getting your rebate in the next two weeks depending on the last two digits of your social security number. If you are receiving a check, you may have to wait until July.

To see when you will get your rebate by, these handy tables created by the IRS will tell you.

Also, check out my poll about what you will be doing with your rebate check in the sidebar. The poll closes at midnight on May 8th.

The Building Envelope

Source: Creative Commons Image on Flickr by magnetha

One of the most important things that you can do in your home is to seal it tight and insulate it right. A properly weather sealed and insulated home will keep you more comfortable and cost much less to maintain. If you rely on fossil fuels to heat your home, or electricity to cool it, now is the time to get an energy audit with a building envelope specialist. If you're not sure how pressing this is, read this article in the New York Times.

In February I went to a workshop at Yestermorrow Design/Build School called Super-Insulation for Zero Net Energy Homes. I learned a lot during the course, but it can be distilled down to a couple of things. First: Any hole in your home will draw air through it. If there is a difference in pressure which can be heat or wind, air will travel through the hole faster. So the protection your walls offer is usually least effective when you want it the most. Second: Not all insulation is equal. The way that insulation gets tested is not realistic, and some insulations are much poorer performers when installed. The worst culprit is fiberglass batting. This is the insulation that almost every home has in its walls and ceiling. The only two types of insulation worth using are foam and cellulose. That doesn't mean that you have to tear out your old insulation, but it does mean that it is under-performing. If you have insulation in your attic floor, you can spray an additional foot or two of cellulose insulation and greatly decrease the amount of heat coming and going through your roof for a very reasonable price. If you have air leaks and drafts, you can often investigate them and seal them up on your own.

I once again have to recommend the book The Home Energy Diet to anyone who wants to do it yourself. It goes through some of the methods of finding those energy leaks, so you can fix them.

In The Bathroom

Source: Creative Commons image on Flickr by betsyjean79

First things first: You need a bathroom fan. Moisture is the enemy of houses, and bathrooms produce a lot of it. While you are getting a bathroom fan, you should step up and buy a two speed one that can be used at low RPM full time and high RPM when you are showering. The need for the two speeds will become more important as you improve the rest of your house and it's good to get it out of the way now.

Bathrooms use a lot of water. If you were building new I would tell you to save some of that water by plumbing for gray water reuse from your shower and sink, but it can certainly be a difficult even for new construction just to make it legal, on old construction you also have to get under the floorboards and replace old pipes as well as installing new ones. This is not for the faint of heart.

But you can still reduce your total water use by installing recent low flow toilets and shower heads. Low flow toilets have improved a lot in the past fifteen years, and now they work just as good or better than the old water hog ones. I don't know about low flow shower heads. I don't get a chance to try many and you only really notice if it's low flow if you don't like it. I wish that there were somewhere You could test them all out, like the Home Depot. I would like to try some of these shower heads from Bricor out, when I move I think I will get one but I have no idea which one.

Quickie: Fireplaces and Stoves

Source: Creative Commons image on Flickr by Adam Melancon

Do you have a fireplace in your living room or study? Do you use it regularly for heating? If you replace it with a modern stove, you won't have to cut as much wood, but you'll still be warmer than before. But what if you want to heat more than just one room with a wood stove? Most people I know who use wood heat do have modern stoves, but their warmth is mainly provided by radiation.

First, a little science: There are three types of heat transfer. Conduction is where heat is transfered between two things that are touching. This is not something you want to do with a stove, it burns. Radiation is where energy travels in waves through space and hits an object. This is how you feel the heat of the fire, it is also blocked by any solid object. Convection is where heat travels through the air by an air current created by the different densities of hot and cold air. Convective currents can travel around corners.

If you want to heat more of your house with your wood stove, you need to get the convective currents moving. The best way to do this is with fans. Ceiling fans that reverse directions for summer and winter use are great for this, but another valuable and inexpensive product is a stovetop fan that is powered exclusively by the conductive heat of the stovetop. It's called the Ecofan. It comes in three models and starts around $100. It moves 100 cubic feet a minute (CFM) for the smaller model and 150 CFM for the larger model. It really does make the whole house more comfortable.
