The Top Ten Cities for Green Roof Installations

In April, the not-for-profit industry association Green Roofs for Healthy Cities released its 2007 lists of the Top Ten Cities for Green Roof Installations. The Top Ten cities in the U.S. are as follows:

1. Chicago IL
2. Wilmington DE
3. Baltimore MD
4. Brooklyn NY
5. Virginia Beach VA
6. Royersford PA
7. Washington DC
8. Philadelphia PA
9. Amery WI

For lists of 2007’s top ten cities in North America and Canada, see the Final Report of the Green Roof Industry Survey.

Pacific Northwest Needs to Get Back in the Running

While Vancouver made the list for the Top Ten Green Roof Cities in Canada, the Pacific Northwest was not represented in the Top Ten for the U.S. (Portland was 9th in 2006). Cities in the Pacific Northwest (Portland and Seattle, especially) are regularly included in ‘Top Ten Green Cities’ lists that are compiled using broader criteria.

Green roof manufacturers incorporate sustainable products beyond the greenery.

If it looks green, smells green and feels green, it must be green. Right? The answer, it turns out, is more of a maybe. It is common knowledge that green technology has large positive environmental impacts: large-scale energy savings, run-off reduction and heat reduction among their chief assets. But as green builders continue to define the standards and guidelines for sustainable construction practices, different levels of earth friendly products continue to circulate the market. Green roofs in particular are taking a harder look at the sustainability of their component materials.

Make it last
Brad Budde of Conwed Plastics, Minneapolis, Minn., believes the future development of sustainable green roof products lies in the hands of builders. He suggests that as companies continue to understand the commercial concerns regarding the application of sustainable and earth friendly products that the market as a whole will become more educated about their applications, benefits and uses.

His company is a leader of earth friendly, compostible packaging materials as an alternative to traditional plastic bags, as well as biodegradable plastics that don’t leave the harmful, long lasting resins of other industry plastics. “It’s a really great product that solves some of the disposal concerns for traditional plastic products,” he says.

Like other wonders of the modern world, these amazing green wonders are places you must see before you die. These structures are unique in the world for their brilliantly creative methods of melding aesthetic beauty, functional design and environmental sustainability.

Built in Darmstadt, Germany, this structure is called Waldspirale or “Forest Spiral.” It was designed by Friedensreich Hundertwasser, a celebrated Austrian architect and painter. Planted along the 12 floors of the rising roof are beech, maple, and lime trees. The structure even incorporates a running stream. The building comprises 105 apartments. In the tower on the Southeast corner, a restaurant and cocktail bar rises over the entire structure. Source: Wissenschaftsstadt Darmstadt.

Nestled in Pembrokeshire, in Southwest Wales, this structure is truly an eco-dream home. It was built about three years ago by a single family and their friends over the course of four months. The family estimates that it took about 1,000 to 1,500 hours of work and cost only about £ 3,000. It was constructed mostly out of logs, straw and mud, which acts as an effective insulator. According to the house’s inhabitants, the home “feels gentle. Feels to me more like being part of the (natural) world, less like a commodity in a box.” Source: Simondale.

At some point in the useful life of most houses, the roof needs to be replaced. An EPA report prepared in the late 1990s calculated that almost 4 million homes per year have their asphalt roofs replaced, leading to the generation of 6.4 million tons of asphalt roofing waste. (Table A-8) Because of this, roofing materials are one of the larger contributors to landfill construction debris. And most of the materials used in making shingles (the prevalent form of roofing used in North America) are not readily recycled into other useful forms, leading to a stream of materials filling up the landfills.

Roofs are subject to extremes of temperature, receiving the full exposure of the sun as well as suffering from the extremes of cold. No other part of the average home sees a wider cycle of temperatures. Precipitation and wind also provide a constant eroding force that wears at the roof and gradually contributes to breaking it down. Because of this exposure to the elements, roofs are typically elements that need to be replaced several times over the life of a building.

Are there greener options than a basic shingle replacement?

We noted a few weeks ago that Instructables, in conjunction with TreeHugger, was holding a Go Green! Design contest. We wanted to feature some of the DIY projects here on Green Options as well. We won’t necessarily be featuring the winners, nor will we be spelling out the steps of the projects (after all, that’s what the Instructables site is for). But we want to spotlight some of these
