Green Options

For a growing number of people, sustainable living means endeavoring as ecopreneurs for organizations with missions they believe in while working in a “green office” space that incorporates green or sustainable design. Typically, “green design” addresses energy efficiency, preservation of resources and the minimization of detrimental effects of construction - if not also improving the health and well-being of the local community as a whole. Some ecopreneurs might work from a home green office, like me, while others find it necessary to gather in office spaces that are, in various ways, ecologically sound and healthier for all.

In State College, Pennsylvania, I had the opportunity to tour the 2,400 square feet Matson & Associates Eco-Building, home to three ecopreneurial enterprises: Matson & Associates, an environmental assessment services company, often engaged to provide “expert witness” testimonials on some of the most timely waste processes issues; Envinity, a green building and home energy audit consultancy; and Matson Biofuels, a company developing a more ecological and non-toxic approach to making biodiesel called Green Biodiesel. For all three of these triple bottom line green enterprises, it’s not just what you create with your product or service — but where you work to create it.

As one of the first examples of green architecture and integrated energy efficient design in State College, the Matson & Associates Eco-Building received the Energy Star certification as a residential office in 2007. The Energy Star certification designates buildings that use 30 percent or less energy than similar code compliant buildings. As an added bonus, the construction cost of this green building was no greater than that for a conventional one.

Former Canadian municipal councilor David Braden, has built himself a completely energy efficient, off the grid, and furnace-free (!) home using current building techniques.

According to Braden

I don’t want to be conveyed as a hippie. I want to get the message to the mainstream. People need to know that in fact there is a great solution sitting right in front of us.

At the heart of the house’s ability to be energy efficient and furnace free, is its design: using a combination of south-facing windows and extensive insulation, heat loss is near-negligible due to the design being almost airtight.

Every once in a while you come across an idea that just lights you up. Styrofoam has long been one of the unmoveables when it came to recycling (too bulky, not much money in it) and there wasn’t a viable replacement for it. Easy to make, lots of it, hard to sustainably dispose of, what are you going to do? Reducing the amount of it in packaging is one path, but is only less bad. What about an option that is all good?

I found a contender: Ecovative Design has come up with a number of products for packaging, building insulation, foam core (think: surfboards) and ye olde beer cooler that do away with styrofoam, using agricultural waste. And, making this even better, the ingredients for the product will come from local sources, whichever is the most prevalent in the area that it’s made.

So rather than trucking the same ag waste 1000s of miles to other regional factories, they have come up with a product that can flex what it contains without compromising the quality or integrity. For example, cellulose pulp from areas with lots of paper mills, and rice hulls in Texas, where a lot of rice is processed.

And it’s compostable, biodegradable, and if sent back to Ecovative, recyclable. Take that, styrofoam!

Recessed can lighting is a familiar method of lighting rooms.  Rather than having fixtures protruding into the space, the light source is hidden in a recess in the ceiling, reducing glare.  But, when the ceiling above is insulated, the can light fixture is a potential source of air leaks and thermal bridging.

I recently got a press release from a company advertising a product to quickly and easily “convert” recessed can lights to a pendant light look.  But, after a brief look, it turns out to be a particularly bad case of greenwash.

Editor’s note: Hopefully, a tax rebate or economic stimulus check is in the mail for you. Our friends at Low Impact Living have some ideas on ways to invest that money in your home… and the environment. This post was originally published on Monday, May 12, 2008

We know that many of us will need to spend our tax rebate check on critical items like food or rent or paying off debt. But just in case you have some of your tax rebate check left and you’re looking for eco-friendly ways to spend the money, we have some ideas we’d like to share with you.

And we’ve geared these tips to supporting the US economy, so you get to do the right thing for the planet and be an eco-patriot at the same time! In coming up with our list of ideas we decided it would be good to recommend ideas that reduce our negative environmental impacts but also support US manufacturers and service providers. So here are five eco-smart ways to use your rebate to support the Earth, the US economy, and save your household money in the long run.

1. Buy a high-efficiency water heater. A high-efficiency water heater can cut your energy use, water use, carbon footprint and even utility bills (over the long run). For most homes you can get the heater itself for $600 - $1,200, but you’ll probably have to spring for installation as well. Models made in the US include the AO Smith Vertex (a storage model that beats the pants off of tankless HW heaters), electric models made by American Tankless Water Heaters, and natural gas tankless heaters made by Rheem (some made in the US).

Aerogel is almost a product out of science fiction.

Nicknamed “frozen smoke,” aerogel is extremely lightweight material, with a density only 3 times that of air. Only a small fraction of a volume of aerogel is the material itself. Most of the volume is filled with air. This makes aerogel an excellent insulator. (Aerogel provides nearly 40 times the insulation of fiberglass insulation.)

Aerogel can withstand great pressures and is also an excellent sound insulator. Aerogels can also be used to absorb airborne pollutants and have been used to clean up oil spills. NASA also used a section of aerogel as part of its Stardust probe to collect samples of material from the tail of a comet.

Aerogel is available for some high-performance applications, but due to its high cost, it has not been widely used. However, new research from a Malaysian scientist offers the potential to drastically reduce the cost of producing aerogel, and could lead to new possibilities for its use as a building and insulation material.

It is time to start thinking about getting our homes ready for winter. Maintenance and repair work done while the weather is still mild will pay off not just in the coming cold weather, but with year round benefits. Here are five common issues to think about when considering your winterization projects, and how to avoid making some common mistakes while improving your house.

In April, home improvement retailer Home Depot launched its Eco-Options program in the United States. Designed to help customers identify products that have less of an impact on the environment than their counterparts, Eco Options has received both praise and criticism around the blogosphere. Last week, I had a chance to talk with Ron Jarvis, the company’s Vice President of Pro Business, Tool Rental, and Eco Innovation (pictured on the right),

Photo Credit: InsulockInsulated concrete forms (ICFs) are an alternative method for building concrete walls. They are most typically used for foundation (basement) walls, but can be used in some other applications as well. Of course, they offer green benefits.

The most obvious improvement offered by using ICFs is the addition of insulation. Concrete has a very low R-value (an 8" thick concrete basement wall would typically have [...]

Photo Credit: Bonded LogicThere are many, many different options available for insulating a building. Whether for new construction or for an addition, there are many manufacturers and different products which all are meant to accomplish essentially the same thing: controlling the temperature inside the building. Without getting into alternate construction methods, consider some options for insulation in standard frame construction.

Insulation is generally material inserted in the spaces between [...]
