Don’t Toss Money out the Window
Read this issue of Greentips online
Windows let the sunshine in, but in many cases they also let the heat in (or out, in the winter). According to the Department of Energy, heat transfer through windows can account for 10 to 25 percent of your heating and air conditioning costs. Older, single-paned windows are the biggest energy wasters.
Replacing older windows with energy-efficient ones can be expensive, but will save you money in the long run by reducing your energy use as much as 30 percent. Energy Star-rated windows are twice as efficient as typical models sold just 10 years ago. A variety of factors determine a window’s energy efficiency:
- Solar heat. A window’s solar heat gain coefficient (SHGC), a value ranging from 0 to 1, indicates the fraction of incoming solar radiation admitted through a window. The higher the number, the more heat will be transmitted, so you want a high value in colder climates (to take advantage of free heat provided by sunlight) and a low value in warmer climates (to keep heat out and lower cooling costs).
- Heat transfer. The rate of heat transfer between the inside and outside of a home (unrelated to solar radiation) is known as a window’s U-factor, which generally ranges from 0.2 to 1.2. The lower the value, the less heat is lost from your home—especially helpful during the winter. Some double- or triple-paned windows also contain argon, an inert gas, between the panes to minimize heat transfer.
- Glazing. Most energy-efficient windows are coated to help reduce heat transfer. Low-emissivity (or “Low-E”) coatings, composed of microscopic metal particles, reduce heat transfer by 40 to 70 percent while still allowing most light through. Tinted and reflective glass are also available, but they block some incoming sunlight as well.
- Framing. Aluminum is a poor choice for window frames because it conducts heat readily.
Windows purchased in 2009 or 2010 that meet specific efficiency criteria are eligible for a federal tax credit equal to 30 percent of the purchase price (up to a maximum of $1,500 for all qualifying home improvements). See the Related Resources for information on eligibility criteria.
If you can’t replace your old windows now, there are other steps you can take:
- Seal air leaks around windows with caulk or weatherstripping.
- Affix Low-E coated film directly to windows to help reduce heat loss.
- Install storm windows to reduce heat loss from single-pane windows by 25 to 50 percent. Low-E storm windows can cost less than a new energy-efficient window.
- Use insulating window treatments including shades, curtains, blinds, or awnings to block incoming sunlight in summer and keep heat in during the winter.

I'm no master gardener, by any stretch. Lucky for me, Boulder recently had a free "Vegetable Gardening for Beginners" workshop. Massachusetts has much more fertile soil than Colorado (and also the absence of summer hail, high winds, oppressive UV radiation, dry conditions, etc.), so I really needed this workshop. I learned what grows super easily here (radishes, tomatoes, potatoes, and greens), what it's possible to grow with some care and attention (lettuce, strawberries, peas and beans), and what does not do so well (carrots, asparagus). I'm really excited to get my plants in the ground, but around these parts I learned I have to wait until after the danger of the last hard frost, which is May 15th. And all that the presenters required of the sixty or so participants was an agreement to share the harvest with neighbors, friends, or Community Food Share. How is THAT for walking the walk! I'm so excited to get my hands dirty; show my kids again the wonders of growing food from seed; eat some yummy, healthy, organically grown food; and share it with people who need it!

Ecological Internet (EI) welcomes the U.S. Environmental Protection Agency's ruling today that carbon dioxide and other greenhouse gases "may endanger public health or welfare", a finding that opens to door to future regulation of such emissions under the Clean Air Act. EI continues to demand that emission cuts be fast and large, that Congress not weaken planned E.P.A. carbon regulation, and that Congress abandon cap and trade legislation for a simple, highly effective, carbon tax. And that the U.S. leads at Copenhagen or feel the consequences.
The E.P.A said in its proposed endangerment finding that "based on rigorous, peer-reviewed scientific analysis of six gases – carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride – that... these gases are at unprecedented levels as a result of human emissions, and these high levels are very likely the cause of the increase in average temperatures and other changes in our climate." Human health and welfare was thus threatened by increased severity and intensity of storms; more frequent drought, heatwaves, and forest fires; rising sea levels; and harm to water resources, agriculture, wildlife and ecosystems.

We are in the midst of establishing a new garden at the Hurley School in Boston's South End. Due to a shortfall of volunteers last weekend, we are putting out an urgent call for help so that we can complete the project. Please join us on Thursday evening for any amount of time between 4-8pm or on Sunday from 12-4pm.The project involves restoring a garden space to include edible and insect-attracting plants for our Outdoor Classroom students to study, care for, and harvest. The program at the Hurley School serves over 100 kids with hands on environmental science lessons twice a week.Volunteering is also a good opportunity to learn about organic techniques and using edibles in the landscape. Please respond to this message or call our office if you are interested in signing up. We will provide instructions and directions for the events.

The Campaign for Safe Cosmetics released a report revealing that toxic chemicals, like 1,4-dioxane and formaldehyde, are in baby products. Both of these chemicals cause cancer in animals, and formaldehyde is also known to cause skin rashes in people who are sensitive to the chemical.
Johnson & Johnson responded by saying "The trace levels of certain compounds found by the Campaign for Safe Cosmetics can result from processes that make our products gentle for babies and safe from bacteria growth,” and the Campaign should stop “alarming” parents. Please email Johnson & Johnson and let them know that that "a little bit of carcinogen in baby shampoo is OK" is NOT an acceptable stance! Click here to act http://bit.ly/jjaction.
