Solar Thermal – Hot Water for Domestic Use

Monday, October 19th, 2009

My mom passed away in 2006, and her estate was finally settled in 2007. I had no idea what my brother and I would inherit, and from what the attorney, stockbroker and CPA said, it sounded meager. I was thrilled to find a check in my mailbox that would get me started on my remodel! Meager to a big-wig, perhaps, but abundant to someone living simply.

The first thing I looked into was solar thermal – hot water from the sun for domestic use. From www.energysavers.gov:

Solar water heaters – also called solar domestic hot water systems – can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use, sunshine, is free.

Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don’t.

Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.

After much research, like that above, I called a solar installer, Valverde Energy. The owner, Larry Mapes, came out to the house to do an assessment. We first talked about my current and future water use. My two teenage daughters were going to fly the coop in the next few years, so water usage would dwindle. All those long, hot showers, mounds of laundry and constant dirty dishes would be a thing of the past when I settled back into living alone as I had done before having children.

So instead of creating a system for a family of three, which would be big and inefficient just for me later on, we decided on a smaller system that would be adequate for all three of us, and would rely on very little natural gas back-up as our numbers shrank. This smaller system could be expanded when the house is sold and another family moves in.

Once we’d made that decision, we talked about infrastructure. This isn’t very exciting and is nothing anyone sees, but it was necessary to get it done.

I am on a shared well with three other homes. For years, we have talked about putting in new water lines, but not everyone had the money at the same time, and our bank account wouldn’t cover it all. I went ahead and replaced the aging line to my house. The stub-in had to go in a certain place to accommodate the solar system, since I was moving the hot water heater as well.

Larry suggested tapping into the natural gas line in the new road adjacent to my property. My gas supply was currently propane, which is more expensive, and he said this alone would cut my energy bills. It didn’t take much to persuade me to switch! The water line came in from the south, and the gas line came in from the north. My yard was chewed up all the way around! Ah… remodeling…

stubins_3428 The infrastructure upgrades needed to be done first, because those utility lines had to be in place for Larry’s crew to install the solar system and before we could pour a slab for the greenhouse. We joked that most women don’t care about these kinds of things in a home, because you can’t decorate them, but I was excited about the value of what he was proposing.

I quietly thanked my mom for making this possible. 515

The Solar Greenhouse Gets Built

Monday, October 5th, 2009

I will spare you the entire thought and building processes and show you what we finally decided on.

remodelimg_3285 Since this is southwest orientation, my main concern was getting extra light and heat, since the winter sun does not come around to that side until late morning. I put three fixed skylights along the lowest part of the ceiling, which has worked well. The sun comes through them a few hours before it gets to the front.

In the New Hampshire house, the south facing windows were floor-to-ceiling. I wanted as much sun coming in as possible for daytime heating. Here in Taos, I wanted a planting bed close to the windows for maximum light, so the windows are in the 5′ space above the 3′ deep planting bed. In both instances there is a 1′ spacer between them for support.

Ventilation is as important as heating. Plants and people don’t like temperatures that are too hot, as much as they don’t like them cold. To keep everyone and everything comfortable, I installed:

  • A glass door flanked by two double-hung windows. This allows more sun in winter and serves double duty to ventilate in summer.
  • Two double-hung windows in the end wall
  • Two VeluxR operable skylights in the upper part of the ceiling. This is where heat will rise, which made it the most logical place for a moveable vent. Air moves in through the windows carrying the heat out of the top vents. Moving air is cool air, so opening the windows and the vents cools off the greenhouse, even if it is hot outside.

The soil in the bed is to be part of the thermal mass. It will absorb the sun’s heat to keep the temperature levels even and keep the plants warm. The concrete floor and an adobe-lined wall on the northern side are also mass that will absorb sun and ambient heat to radiate back out at night.?remodelimg_3526

The ceiling is super insulated, and exterior doors lead into the four rooms of the house. There is no supplemental heat in the greenhouse. In the event there are many cloudy days in a row or old-timey winter temperatures of 40 below, I will sacrifice the plants as the greenhouse gets cold, but the heat in the other rooms will not be lost. The girls have small gas heaters in their rooms for the coldest days and nights.

remodelimg_3531 The work was done enough by Thanksgiving to start seeing the benefits. My fuel bills that following winter were half of what I’d been used to paying. I cut my wood consumption by half with the new ceiling insulation and double pane windows, and my natural gas bill was about $40 a month at it’s peak with the girls using their heaters.

Come spring, I got an energy audit and a surprisingly good HERS (Home Energy Rating System) score.?remodel.gh.1.09_3880

Being Green as the End and the Means

Tuesday, May 26th, 2009

For the past few months now I’ve been working toward starting an agricultural business that will be powered by alternative energy, restored to meet green certification standards, and managed with the goal of achieving profitability through sustainable business practices. In order to understand what’s really involved in building a green business, I’ve spent all of my time learning adiary_and_penbout other organic businesses, researching alternative energy technologies, tracking down grants, loans and funding options, and pitching my project to anyone who would listen.

By centering my business around the concept of long-term environmental sustainability, I am standing up to the status quo, and making a statement that I will not compromise when it comes to doing what’s right by the environment. I know that building a green business from scratch isn’t cheap – I’ve done the research, and I know that it will cost me more to build sustainability into my business than it would were I to throw those philosophies aside.

Money isn’t everything, and I believe that by doing what’s good and what’s right, I can succeed and build the business of my dreams. And while I do understand the practical realities involved in starting a business, buying a farm, and installing all kinds of energy projects, I’m also learning that there are organizations out there who are dedicated to helping people like me grow these kinds of businesses.

native-energy A few weeks ago I received a message from a young man named Owen. In his message, Owen introduced himself, explained that he worked for a company called NativeEnergy, and stated that he had been given my business card at the Craft Brewer’s Convention a few weeks earlier. I had been at the Craft Brewer’s Convention (part of the business I am developing is a commercial hop farm), but didn’t recall meeting Owen, and had never heard of NativeEnergy.

hops-september-12-2006-1

Our "test crop" of hops.

NativeEnergy, I’ve since learned, is a carbon-solutions consulting company that helps business reduce their carbon footprint by selling carbon offsets and renewable energy credits, and also by investing in companies that want to install renewable energy projects. Having heard of my plan from my Development Officer (aka “mom”), Owen contacted me to learn more about my project and offer ideas on how NativeEnergy and I could work together.

Founded in 2001, NativeEnergy is based out of Burlington, Vermont, and has helped well-know companies, including Stonyfield Farm, Timberland, and The Dave Matthews Band, to install renewable energy projects and offset carbon emissions. The company helps businesses understand their options when it comes to creating carbon neutral projects, and points organizations in the directions they need when it comes to the early development of their plans. At the same time, NativeEnergy works with carbon emitting businesses to help them offset their carbon pollution.

Since receiving that initial message from Owen, I’ve had 2 productive conversations about my business, NativeEnergy’s initiatives, and what I can do moving forward to try and develop my renewable energy projects to line up with NativeEnergy’s model. And even though I’m still in the early stages of building my business (I don’t even own land yet), the people I’ve talked to have been helpful, enthusiastic and eager to see me succeed. It amazes me that thsustainable-windere is a business out there who contacted me, who wants to help me, and who may eventually play a role in actually financing my dream!

When I realized that I had to build this farm, and do it in the greenest manner possible, I empowered myself to challenge the way business has always been done, and make change happen from the bottom up.? So even though I don’t have a farm yet, I’ve already invested time and energy in figuring out what I need to make my farm sustainable. Building a business like this – with a mind to what REALLY matters – is a win-win situation. By planning for the long-term health of the earth and environment, I think that I am planning for the long-term success of my business and my vision.

Becoming an Ethical Consumer

Monday, March 2nd, 2009

When you make purchases, are you careful to buy goods that are ethically sourced, Fair Trade, certified organic or made in the USA? Are you conscious of the path your dollars take once you’ve handed them over to a sales clerk or entered your credit card number in an online site? Do you care about where all of the materials used to manufacture the things you buy come from? If you answered yes to these questions, than you’re already on the road to becoming an ethical consumer, and following the principles of ethical consumerism when spending your hard earned money.

According to Knowmore.org (a site dedicated to raising awareness of corporate abuses and directing grassroots action against unsustainable corporate practices), Ethical Consumerism is “…a movement toward corporate reform, through which individuals recognize their own role in systems of oppression, and take personal steps toward resistance and positive change.” Ethical Consumerism encourages people to recognize the significance of collectively organized individual actions, and use that power to alter the landscape of traditional economic systems.

Knowmore.org encourages this kind of thinking by offering an online space for like-minded individuals to exchange ideas and find resources focused on combating corporate abuses. One useful tool on the organization’s site is called “Behind the Logos.” Knowmore.org assigns an “ethical rating” to global corporations like Volkswagen, American Express and De Beers that’s meant to help people understand where the products they purchase are sourced and manufactured, and whether the companies making those products are doing so according to ethical principles. With one quick click, you can find out that AT&T received positive ratings for Worker’s Rights, Human Rights and Environmental Issues, but has areas of concern around their Political Influence and Business Ethics.

Another resource for those interested in Ethical Consumerism is the Responsible Purchasing Network (RPN), an international network of buyers dedicated to socially responsible and environmentally sustainable purchasing. The RPN is a member-based organization that provides consulting services and resources for paid members, but also publishes helpful guides for the everyday consumer. You can download Responsible Purchasing Guides that provide information about purchasing sustainable products, finding environmentally-conscious vendors, and working with governments to introduce eco-friendly goods into your state’s procurement policies.

If you’re interested in learning about European businesses, UK-based Ethical Consumer is an organization that researches the social and environmental records of companies, publishes free buyers guides, and scores companies based on how well they’ve incorporated ethics into their business models. You can become a member of Ethical Consumer to gain full access to their resources and services, otherwise you might have to pay a fee to access some of the research and information that’s on the organization’s website.

By educating yourself about the consumer choices you encounter on a daily basis, you take control over how you use your spending power to transform business practices and the greater economy. Once enough people realize that they can impact the process by only giving their money to ethical businesses, than real change can take place. If people continue letting big companies off the hook, and spend money with those businesses who practice socially irresponsible manufacturing, who invest their money (which is really your money) in corrupt organizations and governments, and who ignore the working conditions of their laborers, than those companies will keep on acting unethically.

Spend your money wisely and make sure you educate yourself before you open your wallet!

Where Do You Get Your Eco-Information? (Part 1)

Monday, December 22nd, 2008

Let me start by admitting that I am a total news junkie. I spend way too many hours researching, reviewing, investigating, bookmarking, and searching for information on all kinds of issues, especially those relating to all things green. In the year that I’ve been writing for GreenBuyGuide, I’ve compiled a list of 1000+ eco-based resources, blogs, organizations, companies and news sites that I use when researching upcoming blog posts.

When writing these posts, I try to find the most up-to-date, accurate and interesting research to support my claims and add credibility to our site. In doing so, I’ve noticed that it takes time to really know which sites offer reliable, substantive data, and which sites are compromised by political agendas, corporate sponsors, or incomplete offerings.

As a holiday gift to my readers and to the other environmental researchers and writers trolling through the web in search of good sites, I have compiled 2 blog posts packed with excellent eco-resources. As always, I am open to suggestions and appreciate learning what others out there already know about the eco-issues affecting our communities, nations, and world.

General Interest & Data Sources

Environmental News Network (ENN) – The Environmental News Network is a mainstream news site that publishes comprehensive environmental news in an easy-to-understand format.

Do You Have a Sustainable Lifestyle?

Monday, October 20th, 2008

When you consider how you live your life, what principles you hold dear to your heart, and the intersection of your actions and beliefs, does everything add up? There are many of us out there who are truely committed to sustainability, yet still struggle to incorporate the concepts into our everyday lives – and that’s OK. As I mentioned in a previous post, there are plenty of eco-sins that I’m constantly trying to overcome, but I still haven’t broken all of my bad habits. And while I feel guilty when I continue to commit actions that impact the Earth negatively, I also understand that my ability to achieve a wholly sustainable lifestyle is tied both to shifts in my thoughts and actions, and also to shifts in how society as a whole thinks and acts.

To better explain this concept, I went in search of organizations that actively promote sustainability. The Sustainability Institute (an organization focused on understanding the root causes of unsustainable behaviors in complex systems, and shifting society toward sustainability) has developed a philosophy that I think defines and explains this concept clearly:

“…unsustainability does not arise out of ignorance, irrationality or greed. It is largely the collective consequence of rational, well-intended decisions made by people caught up in systems – ranging from families and communities to corporations, governments and economies – that make it difficult or impossible to act in ways that are fully responsible to all those affected in the present and to future generations.”

The EPA has basic information about sustainability available on their website, though I must admit that I no longer fully trust the organization’s integrity and commitment to creating and disseminating unbiased scientific information. I loath to make such a statement, and hope that my feelings of mistrust toward the civil servants who work at the EPA will end once this administration is removed from power.

In determining whether my current lifestyle is sustainable, I decided I needed to first ask myself what it means to live sustainably, and from there determine if my lifestyle choices fit the model.

Here are the questions I have been pondering – I haven’t answered all of them for myself yet, but plan to write more about this as I figure out what sustainability means to me. Take some time and ask yourself the same set of questions, let me know if I have missed anything in my list, and feel free to share your definition of what it means to live a sustainable life.

Food: What do you eat? Where are the foods and beverages you consume grown, manufactured, processed and packaged? Where do your food dollars land once spent? Is your food money removed from the local economy and sent to some faceless corporation, or does it benefit others in your community? How is the food you eat produced? Have you ever met any of the people responsible for growing or making your food? How often do you eat out? Do you use reusable mugs for coffee and other drinks? Are fossil fuels used to make,? process, package, distribute what you eat?? How much waste is produced as a result of your food purchases? Do the foods you consume nourish you or simply feed you? Do the foods you eat contribute to your overall mental and physical health?

Housing: How do you live – alone or with others? Do you live in a new building or an old building? Is your building energy efficient? What kind of energy powers your home? How much energy do you use on a monthly/yearly basis? Do you have excess electronics in your home that increase your energy bills? Do you use any reusable resources to power your home? Do you have more space than you need in your home? Do you take measures to ensure you are not wasting excess energy in your home? What products and chemicals are used in the upkeep and maintenance of your home? Do you use eco-friendly products in your home when possible? Do you have a yard? If so, how is it maintained? Do you have grass that needs to be mowed and fertilized? Do you have a garden? Do you use chemicals to maintain your outdoor space? Do you use water to feed the grass and other plants? When working on your home or outdoor space, do you consider the environment and select materials accordingly?

Transportation: How do you get around? Do you walk, bike, take public transportation, drive, carpool, fly? How often and how far do you travel when you leave home? Do you own a car? If so, what kind of gas mileage do you get, how efficiently does your vehicle burn fuel? If you own an older car, does it meet emissions standards? Where do you go and why do you go there? Do you ever carpool? How far do you live from the places you visit the most often? Are there car trips you take that are unnecessary? Do you walk when you need to go someplace within a mile of your home? Have you taken steps to reduce your reliance on petroleum as a fuel?

Consumer Behaviors: What do you buy and why? Do you need all that you purchase? Do you reuse what you can and purchase new things only when you need to do so? Do you throw away things because they’re broken, worn, stained or old? Do you buy goods from environmentally-conscious companies? Do you consider the ecological footprint of your purchases, including the materials used and externalities created? Do you buy eco-friendly products? Do you consider the impact of your consumerism on the environment before you make any purchase? Where, and under what conditions, are the products you purchased manufactured? How far do those products have to travel to reach you? Are your consumer dollars used for corporate profits or are the people who make the products being paid a fair wage (or both, if possible)?

Waste: Do you recycle what you can? Do you compost your organic waste? Do you take the time to sort and process through all of your waste products in order to send as little as possible to landfills? Have you gone paperless in areas where it’s possible? Do you encourage recycling at work or other places you frequent and have an impact on policy? Do you pick up trash on the street? Do you refrain from throwing out recyclables until you can find a recycling container? Do you package food in reusable containers instead of one-use packaging? Do you use things until they can no longer be used? Do you make it easy and convenient to recycle at home? Do you have a dedicated space where you store recycling materials and do you have recycling tagged as a dedicated task assigned to someone each week? Do you resist the urge to print?

Family: Do you encourage your children to reduce, reuse and recycle? Do you feed, clothe and gift your children with organic and eco-friendly goods? Do you explain why it is so important for people to tread lightly on the Earth? Do you encourage eco-practices in your childrens’ classroom? Do you set a good example and practice what you preach to your children (and not just when they are watching)? Do you ever say no to buying things your children want because of the negative ecological impact those purchases have? Do you stick to your eco-principles when it comes to birthday parties, Christmas, and other “special events” and holidays?

These questions are by no means exhaustive – rather, they are meant to get you (and me) thinking about the everyday practices of sustainability, and help us define what we all need to do in order to live sustainable lifestyles. I certainly don’t have the answers to all of these questions, and I fear that some of my favorite things in life (chocolate, coffee) are generally not considered sustainable goods (in my defense, I buy mostly organic, fair trade chocolate). Living sustainably isn’t necessarily going to be easy though – it will require sacrifices and compromises. In an era of uncertainty and impending environmental degradation however, it’s time we all stood together and started making the hard choices and doing what’s not fun and what’s not easy.

Party’s Over Folks, It’s Time To Get Real!

If you’re interested in learning more, check out the Wikipedia entry for sustainability – there’s all kinds of information about the various types of sustainability, as well as links to scientific references, articles and websites.
