So you’re renovating, or maybe even building something new, and you’ve finally finished framing out your new walls. Now you’re ready to put up your drywall and maybe some tile, or maybe even wallpaper—but what about the ceiling? Sure, you can just drywall it too (and hopefully you’ve been using recycled-content drywall), but there are several other options to consider as well.

The decision of how to make your ceiling can be influenced by a number of factors beyond your decorative choices. A few things to keep in mind are how much sound transmission in and out of the room you want to allow, whether water and/or humidity will be present, whether the room’s activities require any particular kind of acoustics, and whether you’ll be applying tiles.

Here are a number of green products designed for ceiling use that you may want to consider, and some ideas on how they might best be used in your building project.

1) Recycled Content Drywall
If you’re not already using drywall with recycled content for your walls, your ceiling may offer another opportunity to include it. Typical drywall is made of a core of mined gypsum and two outer layers of non-recycled paper. The mining of gypsum typically launches large amounts of particulate matter into the air, threatening both the respiratory health of the miners and the air quality of the surrounding areas. And like most mining, the extraction process leaves large scars on the landscape at the mining site, and often contributes to soil erosion on the slopes where it is mined.

Instead of mined gypsum, recycled-content drywall is made of synthetic gypsum—a byproduct of the process coal-fired power plants use to limit the amount of acid-rain-causing emissions they release into the air. And not only does the use of synthetic gypsum reduce manufacturing waste, but it’s purer than mined gypsum, making for drywall that’s stronger and easier to work with. As an added benefit, the paper facing used on recycled content drywall is 100% recycled.

2) Tectum Interior Ceiling Panels
A dropped ceiling of rectangular panels, typically made of sound-absorbing (acoustical) materials, is another option. A dropped ceiling consists of a grid of lightweight metal strips that are hung from either exposed beams or a drywall ceiling, which hold the panels in place without screws or adhesive. This allows for easy access to any wiring or ductwork underneath, as well as easy replacement of any panel that needs it. Acoustical panels reduce the amount of noise bouncing around within the room, while also limiting the amount of sound traveling through the ceiling to rooms above.

For a green option, Tectum interior ceiling panels are made of wood fibers that are bound together without chemicals and come from Aspen trees grown in FSC-certified forests. The air-drying, low-energy binding process uses only sand, limestone, salt, magnesium oxide (from seawater), and water that gets recycled after use. The finished panels don’t off-gas at all, and are non-toxic enough to be added to compost piles for soil amendment. So not only do you get a quieter room, for a healthier indoor environment, but you get it without hurting the outdoor environment either! And for even further reduction in the noise coming out of the room , take a look at QuietRock Soundproofing Drywall.

3) Durock Cement Backerboard
If the room you’re building is a bathroom or kitchen, or any other room where high humidity and spilled water are common occurrences, you’ll need to use backerboard –commonly called “blue board,” because a common brand is (you guessed it) blue. Backerboard is typically used underneath tiles even in dry areas, where it acts as a surface stiff enough to keep the surface from flexing and pushing them off—and in wet areas, it provides a layer of water-blocking protection for the framing and surrounding rooms.

Durock cement backerboard is not only resistant to moisture, but mold as well, protecting the room’s air quality. And concrete is so durable that it’ll be a long time before you have to replace it, which saves the waste of valuable resources. And it’s even made of recycled materials—it’s 10-20% recycled fly ash.

Are you one of the millions of Americans trying to make your dollars stretch by taking a “staycation” this summer?  Hanging around the house can be a good thing. You get to tackle projects you don’t have time to get to during the year, and you can invite friends over who you never see—even though they’re local.  You invested in all that patio furniture, in your deck, in your barbeque—so show it off by making a nice dinner for friends and serving it outside in the backyard.

We’ve got a couple of recommendations for green products that’ll help you entertain in style, without sacrificing your environmental values.

Soji Solar Lantern

Light up the evening with the Soji Modern Solar Lantern. These elegant lanterns have a solar panel that collects sunlight during the day, stores it in a rechargeable AAA battery,  and then lights up the night with very efficient LED lights. They’re portable and freestanding–they don’t require extension cords running across the grass into the house or garage! Comes on automatically at dusk unless you turn it off.  They’re made from hard plastic, so they’re durable, and they’re pretty affordable, too.

Wasara plates

Whether you’re serving chili, grilled vegetables, burgers and chicken, or old fashioned corn on the cob, make your clean-up job easier by using these cool disposables. Nope, they’re not paper or plastic. Wasara plates, bowls, and cups are made from 100% tree-free rapidly-renewable materials: sugar cane fiber (bagasse), bamboo, and reed pulp. They’re much more elegant than anything you’ll find in your local supermarket, and they fit comfortably in hand.  Strong, oil- and water-resistant, good for hot and cold foods, and best of all: fully compostable. Available in multiple sizes and types.

Fair trade napkins

Use cloth napkins as an alternative to throw-away paper. These fair trade, 100% organic cotton napkins are hand woven by rural women in Guatemala using centuries-old techniques and looms. Income from weaving helps support their families and maintains ancient cultural practices. After the party, just throw them in the laundry with your colors.

Woolly Pockets "Island" planter

Finally, bag spending money at the florist, and consider this cool alternative “plant in a bag” for your table centerpiece: Woolly Pockets Freestanding Islands. They’re made of 100% post consumer recycled plastic felt, and they’re lined so they won’t leak all over a nice table. Fill them with lush plants during the summer, and bring them indoors in the fall to enjoy year-round. Made in New York by a very cool company.

NatureMill composter

When the party’s over, remember to compost your leftover food! Corn cobs, soggy salad, watermelon rinds, and stale buns can all be enjoyed by worms or bacteria and fungi.  Check out the Worm Factory, and the NatureMill composter that fits under the counter in your kitchen. And several months later, you’ll have an excellent, nutrient-packed soil amendment to use in your garden outdoors, or on your houseplants.

Enjoy the rest of the summer!

The dog days of summer are upon us, and many of us are sweltering in the heat. If you live in a big city, you may feel worse than your country cousin due to the “urban heat island effect”. In an urban heat island, temperatures may be 6-8ºF warmer than surrounding rural areas, fields, or woodlands.  Urban heat islands are caused by a combination of factors:

  • Loss of vegetation that shades buildings and cools the air through evapotranspiration
  • Hard surfaces (buildings, streets, and parking lots) that absorb solar radiation and radiate it back to the air/atmosphere
  • Waste heat from electrical use, water heating, car & truck exhaust, and other thermal and mechanical sources

The temperature differentials are worse at night, when hard surfaces like asphalt pavement, brick, and concrete radiate the heat they absorbed during the day back into the air. Calm air also makes it worse.

The urban heat island effect causes a number of problems. It exacerbates normal summer discomfort for everyone—causing people to crank up the air conditioner (and yes, generate more waste heat), and it makes elderly or sick people more susceptible to problems brought on by heat waves. It’s tough, and sometimes dangerous, for athletes and for those who work outdoors–such as construction workers, roofers, police officers and highway workers. Higher temperatures also increase smog formation, which boosts health risks to the elderly, children, asthmatics, allergy sufferers, and those with respiratory problems. Finally, stormwater runoff from paved urban areas causes excess warming in creeks and lakes, which can damage ecology in those environments.

There are a number of green building materials and practices that urban individuals and organizations can use to mitigate or reduce the heat island effect:

Plant trees. In summer, they create shade which reduces air conditioning loads on a building, and in winter, they shield buildings from wind and unwanted heat loss. They also produce oxygen, and create bird & animal habitat.

Green roof with walking path

Install green roofs and walls. These are vegetated, carefully engineered surfaces that support plant life, and keep the building cool. They provide other benefits, too, including improved drainage (protects underlying roof and reduces stormwater runoff), recreation for employees or occupants, and even herb or vegetable growth. Green roofs also improve air quality because plants convert carbon dioxide to oxygen, and filter out other contaminants. Although green roofs may cost $10-$15/sf more than traditional roofs, these costs are offset by energy savings, longer roof life and reduced maintenance costs, and by various grants and tax incentives.

Green Roofs have enjoyed increasing popularity in Europe over the last decade, with government incentives stimulating a multi-million dollar industry.  North American planners, builders and consumers are also beginning to consider green roofs for malls, schools, hospitals, and homes. In New York State, green roofs have been installed at the Bronx Zoo, Cornell University, Pace University, the Bronx County Courthouse, and at Rockefeller Center Roof Gardens.

Install a white roof to increase reflectivity (albedo), so that solar radiation is not absorbed by your roof to be re-radiated later. For flat roofs, Green Depot recommends Bulldog Durex Elastomeric White Roof Coating.  It’s a flexible, mildew- and UV-resistant waterborne roofing topcoat made with 100% acrylic resins. It reflects heat from the roof surface: lowering cooling costs, and extending the life of roof membranes and surfaces. It can be used over a variety of existing roof surfaces, including metal, asphalt, masonry, and EPDM.

After three nail-biting months, it looks like the BP oil spill in the Gulf is finally being sealed. This week, drilling engineers are expected to complete the “bottom kill” relief well linked to the main well that had been capped and plugged on July 15th. A combination of mud and cement will be pumped into the well to plug it permanently. Since the oil spill began, an estimated 190 milllion gallons of oil were spilled into the Gulf of Mexico.

Solar ad campaign from 1BOG

In a post on July 12th, before the successful capping, I described the spill in Prius-mile equivalencies: how many hybrid car-miles could have been driven with the lost oil, and  I said that if 1 million Americans bought hybrid cars in the next year, they could save 270 million gallons of oil–three times more than what had been spilled to date.

The solar dealer 1bog (One Block Off the Grid) has done something similar—but with better graphics—describing the oil spill in solar panel equivalencies.  In one scenario, they take the area affected by the spill (roughly the size of Kansas) and calculate how much power could be generated by a Kansas-sized block of solar photovoltaic panels. They estimate that all the electricity needs of the United States, Central America, and South America could be met by such a vast array: for 25 years. (Why not indefinitely–as one commenter asked? Because after 25-30 years the panels lose efficiency and should be replaced). In another scenario, they point out that the spill has cost BP $32 billion to clean up, an amount, they say, that had it been spent on solar panels instead, could have provided enough electricity for all of Los Angeles County for 30 years.

So it’s clear from these whimsical yet hard-hitting ads that solar can indeed pack a punch if enough is invested in it, displacing significant amounts of electricity generated on the fossil fuel-based grid.

Solar array at Hancock Shaker Village

In my neck of the woods, the Hancock Shaker Village recently installed a photovoltaic array on and adjacent to its visitor center, supplying the museum and grounds with 66% of their power needs.

Residences can do the same thing. With prices for photovoltaic panels steadily dropping, they’re more affordable than ever. The federal government offers a 30% tax rebate (with no cap) for solar installations, and most states have their own tax incentives. You can find your state on the DSIRE website database of State Incentives for Renewables & Efficiency.

Residential PV array by Radiant Complete

In the tri-state area, Green Depot recommends Radiant Complete for residential and commercial solar jobs. Their strengths are in evaluating a project to determine what the clients’ specific goals are (hot water, electricity, or space heating, for example), and the site’s physical parameters (trees and other shading, roof area and angles, building orientation, etc). Then they custom-design a combination of renewable options to fit your needs and budget, and manage the installation using highly skilled professionals.

SolarStar Attic Fan

If you want to cool your house on the cheap and preserve the integrity of your roof shingles and insulation,

Solio Charger

check out the SolarStar Attic Fan. Running on the sun alone (not hardwired into your house), it vents hot air from your attic, keeping the space cooler: preventing destructive ice dams on your roof in winter, and saving you money on air conditioning in the summer.

If you’re a student or a renter on a low budget, there are more green products than ever before on the market. The Solio charger has 3 mini PV panels that allow you to capture and store solar power so you can recharge your cell, iPod and other handheld devices anywhere the sun shines.

Verilux Flashlight

Tired of replacing batteries for your flashlight? You’ll never have to again with the rechargeable, solar-powered Verilux flashlight. Comes with 6 bright LED lights, and casts a wide beam.

So: big or small, there has never been a better time to look at how solar might fit into your life.

Somehow it got to be August, and we’re thinking Back to School.  How many of us realize that our children have become the unwitting generators of a huge amount of garbage?

According to Waste Free Lunches, the “average school-age child using a disposable lunch generates 67 pounds of waste per school year. That equates to 18,760 pounds of lunch waste for just one average-size elementary school.”

With that in mind, Green Depot has just brought in an assortment of lunch storage ideas that will turn the disposable paper sack and the ubiquitous sandwich bag on their heads. These green products are much cooler than the vinyl lunch boxes you pick up every year at Wal-Mart. The ones that are hard to clean and smelly.

Say goodbye to endless plastic sandwich bags!

Fresh Snack Pack

The Fresh Snack Pak is what I bought my two daughters last spring, and they’re holding up really well.  You can put a sandwich in it, or get more than one for chips, fruit slices, etc. They look like a little envelope (folds flat when empty), and are made from EVA (ethylene-vinyl acetate) plastic. They contain no PVC (poluyvinyl chloride), BPA (bisphenol A), or lead.  Just wipe clean with a sponge, or handwash when you’re doing the dishes, and drip dry.

Fluf Lunch Bags

Fluf reusable lunch bags are another cool option. Shaped a bit more like the traditional brown paper bag, the Fluf comes in a few different styles suitable for kids…or just plain Suits. The body is 100% certified organic, pre-shrunk cotton, and the liner is made with phthlate-free vinyl (EVA). It’s removeable, too, for easy washing. A snap closure is easy for little hands to use.

Snack Bag

The handmade reusable snack bag costs next to nothing, and is embroidered with all sorts of whimsical creatures—from chubby little mice to robots.  The outer shell is 100% unbleached cotton; the inner liner is water and stain-resistant nylon. A velcro closure keeps you from…losing your lunch.

Now, for something old and new. The Stainless Steel Tiffin Food Carrier is a sleek, round metal lunch box that’s been used in Asia for years to take food to school or work. New to the States, it’s constructed of food-grade stainless steel, and has sturdy side closures that snap down to keep the lid firmly in place. Each of the two compartments can be heated separately, or refrigerated.

Tiffin Stainless Steel

If you’re sending them to school with pasta salad or last night’s yummy leftovers, the little brats will need something to eat it with. Try these super hardy MicroBites Mini-Utensils. You can use ‘em backpacking, too.

Microbites

You can learn much more on Waste Free Lunches. It’s an an excellent website chock full of tips on how to reduce the amount of trash generated by our kids’ school lunches. Has tips adults can use, too, and even healthy food suggestions.

Using reusables instead of disposables is good for our wallets as parents, and it’s a good way to instill an environmental ethic in our kids.

On Friday, New York State Governor David Paterson signed a bill into law that prohibits babies’ and children’s food and beverage containers from containing Bisphenol A, or BPA. Under the legislation (S 3296H/A 6919D), sippy cups, baby bottles, straws, and pacifiers containing BPA can no longer be sold in New York State. The law goes into effect on December 1, 2010.

Working under the  “JustGreen” umbrella, a coalition of at least 45 advocacy groups worked together for passage of the bill; they included mainstream environmental organizations, consumer groups, health and cancer networks, women’s groups, academic institutions, and environmental justice groups.

According to a press release issued by JustGreen, “New York is now the seventh state and by far the largest in both population and economy to pass phase out of BPA in young children’s products, joining Connecticut, Maryland, Minnesota, Vermont, Washington and Wisconsin. It will be one of the first state laws to go into effect, however. In addition, Maine has declared bisphenol A (BPA) as a ‘priority chemical’ and will institute regulations to phase out its use in children’s food and beverage containers and infant formula containers.  The Massachusetts Department of Public Health is moving forward with similar regulations to cover children’s beverage containers. California has BPA legislation pending.”

BPA has been associated with a wide range of children’s health problems, including “early onset puberty, polycystic ovary syndrome and breast and prostate cancer,” said Senator Antoine Thompson, Chair of the New York State Senate Environmental Conservation Committee.

Because children’s bodies are smaller and metabolize more rapidly than adults, toxins build up in their bodies quickly, and infants have been detected with high levels of BPA in their bodies. JustGreen cited connections between low doses of BPA and “obesity, infertility in males and females, brain dysfunctions, thyroid disruption, heart disease, and diabetes.”

Stephen Boese, Executive Director of the Learning Disabilities Association of New York State, said that BPA has been implicated in learning disabilities and other neurological impairment.

The full press release, and a list of advocates, can be viewed on the Just Green website.

Wee-Go glass bottles

Green Depot Founder Sarah Beatty testified in support of the bill in May, prior to it being passed unanimously in both houses of the NY State legislature (download her testimony here). Since the opening of Green Depot’s flagship store at 222 Bowery in February 2009, Green Depot has put an emphasis on healthy green products for babies and children, including certified organic cotton clothing and bedding, diapers without harsh chemicals, and BPA-free baby bottles. One of our most popular sellers has been the Wee-Go, a glass baby bottle with a soft silicone sleeve that’s easy to grip and prevents breakage. It’s available in 4- and 9-ounce sizes, in six different bright colors.

Green to Grow

Another is the Green to Grow nurser–a bottle that’s phthalate-free, BPA-free, dishwasher safe, and comes in 100% recycled packaging.

We all know that breastfeeding is best, but when bottle feeding is necessary, at least now there are safer ways to do it in New York State.
