So you want to buy an existing green home but don’t know where to look? Or maybe you’re worried about the greenwashing that some use to differentiate themselves due to a souring market? ListedGreen is your savior.

Founder Dave Syring saw a number of problems with the existing major Multiple Listing Service platforms (those used by real estate agents to post homes for sales); Chief among them, were that only real estate agents could access the listings and none were dedicated to green homes. So last March, Syring took things into his own hands and launched ListedGreen, an MLS exclusively for Green homes and properties. This is a sustainable business from the ground up, from its solar-powered servers to its contributions to Global Green USA.

But the real key is in the site’s accessibility and quality control… Continue Reading »

Love the sun and warmth that skylights provide, but wonder what part they play in an energy efficient home?

Skylights can provide you with some energy saving benefits, but there are many things to consider in avoiding some common skylight slip-ups.

Skylights allow sunlight into our living spaces from above without compromising privacy. In delivering abundant daylighting, skylights can reduce energy consumption used for lighting, particularly in interior rooms that do not have direct access to exterior windows.

So, which features should you look for to enjoy the benefits and minimize any negative side effects that skylights can have? Consider the following when evaluating skylights to ensure that they are a bright feature in your home.

Windows are important to the efficiency of our homes and often account for a significant portion of our heating and cooling bills. New technologies are beginning to address common issues, such as solar heat gain and insulation, so that we can expect more from our windows in the future.

What is a SHGC?

Windows allow sunlight into our homes. Sunlight is composed of short and long wavelengths. The short wavelengths represent the visible light that makes our homes bright and sunny. The long wavelengths produce the heat we feel from that sunlight. This heat is also known as solar radiation.

The amount of solar radiation transmitted through a window is represented by the Solar Heat Gain Coefficient (SHGC), a number between 0 and 1. A window with a high SHGC allows a lot of solar radiation into your home. The heat provided can be welcome in colder climates, but provides unnecessary heat in warmer climates. A window with a low SHGC blocks solar radiation, which reduces the need for air-conditioning in summer but is not ideal for cold climates.

Last week I took a tour of NEXUS, Boston’s Green Building Resource Center. An very knowledgeable employee of NEXUS, Shoshana Friedman, showed me around their new space on 38 Chauncy Street in Boston.

NEXUS is more or less the epicenter of green building resources for Boston, MA. It has a product showroom, a material and resource library, space for events, and provide a place for people studying for LEED certification. You can also take a tour of the building from their friendly staff!

I was curious if other similar green building centers exist. They’re a little hard to find—a quick search I did turned up one in Atlanta and one in Santa Monica (which is actually co-sponsored by Global Green USA). Let us know if your searches turn up other green building centers in different parts of the country.

In addition to serving as an educational resource to the building community, NEXUS is a working example of green products in use. They are currently in the process of being LEED certified under the Commercial Interior (CI) bracket. Here are a few “green” features that I found interesting:

Part of building a home with renewable energy systems, such as solar panels, is deciding whether or not it should be connected to the electrical grid. There are numerous considerations — namely practical, economic, and environmental –involved in making your decision.

However, this choice can be difficult without a good understanding of what the terms grid-tied and off-grid actually mean. A grid-tied home is connected to power lines which transmit electricity to the home, mainly from power plants, yet can also produce power on-site using renewable energy systems. An off-grid home is not connected to power lines and, therefore, it relies solely on renewable energy systems to produce electricity and storage systems such as batteries to mediate the supply.

As we examine the practical implementation, cost, and environmental impact of each, we’ll see how being connected to the electrical grid is typically more beneficial than being completely detached from the predictable source of electricity and storage it provides.

New products such as, bamboo flooring or structural insulated panels are making it possible to build healthier, greener homes.

Impact resistant windows are just one of the advances that can make a significant difference in protecting our homes.

Leaving your home vulnerable to hurricane force winds and other damaging conditions can affect the health and life span of your home.

When the U.S. Green Building Council was founded in 1993 it didn’t appear that it would be just an environmental movement. The Council (known as USGBC) sought a marketable approach to green building as a way to transform the built environment.

Out of this idea came the Leadership in Energy and Environmental Design (LEED) program, launched in 2000.

According to Richard Fedrizzi, who became USGBC’s CEO in 2003, LEED was meant to “transform the marketplace towards sustainable building.”

Architect, Sarah Susanka, has helped reduced the popularity of McMansions by introducing a quainter lifestyle, beginning with our homes.

Her book, ‘The Not So Big House,’ embraces the idea that less is more and that luxury does not have to mean excess. So what does this have to do with green and energy efficient homes? How can a smaller home work for you?

A small, modest home means less heat, less air-conditioning, and less lighting. A home with fewer square feet is more efficient because a smaller amount of energy is needed to run the A/C, provide hot water, and perform other energy consuming activities.

So what can we do to make the most of the space we have?

Green homes can look modern and sleek, but what if you want a more traditional looking home? Like a craftsmen or a cape. Holistic Homes is building four green and energy efficient craftsman style homes in Woodstown, New Jersey that are big on style and luxury and small on cost and energy.

Love that new car smell?

That smell actually comes from the upholstery and plastics in your brand new car. Many new materials and everyday products contain VOCs (volatile organic compounds) which enter the atmosphere and can affect our health and the environment.

So what exactly are VOCs, where can they be found and what can we do to avoid them? VOCs stands for volatile organic compounds and are typically human-made chemicals. According to the USGS, the word organic, though typically associated with healthy and natural products, actually means that the compound contains carbon.
