This is the third post in a series on the LEED green building rating system. The first post provided an Introduction to LEED, and the second looked at the Sustainable Sites credit category. Location and Transporation The LEED Location and Transporation category of credits is based on where the project is located, its connectibility to…
As products are developed to be internationally used, it is important that they can be made from local products, wherever they are needed, affordable in those locations, and sustainable in all aspects. Many of these products take years to develop but are a necessity for the future of underdeveloped and overdeveloped areas. One such product,…
China and Singapore are the first countries to collaborate and come up with a suitable answer to what future cities may need to be with the Sino-Singapore Tianjin Eco-city.
Last week, I attended a driving event at the GM Proving Ground in Milford MI. Driving through the campus, there were several places where roads converged at roundabouts (sometimes also known as rotaries) rather than intersections with stop signs. (I’ll have more to say about the content of that event later.) But even before I arrived, I had gone through a couple more roundabouts on the roads in Milford, MI, where GM’s Proving Ground is located. That started me thinking about roundabouts, and how they are greener than standard intersections.
A modern roundabout … is a circle “designed for very low traffic speeds, about 15 mph.” Entrances and exits are curved so that motorists must travel slowly — far different from the rotaries of decades ago, which typically allowed drivers to enter at 35 mph or faster. The Institute says a modern roundabout typically needs to be about 100 feet across so that it can be properly designed to slow the entering traffic. (New Urban News)
Because the traffic only needs to slow down rather than stopping, all the cars traveling through a roundabout avoid the stop-and-go of a stop sign or a red light. Collectively, this adds up to thousands of gallons of fuel saved for each intersection. Avoiding a full stop also allows each driver to get through the intersection faster, which helps make overall travel times shorter.
An article on the ABC News website with the provocative title "Going Green: Fad or the Future?" suggests that while right now "green is the new black," the long term-prospects for the green movement are less certain to remain as strong and as much a part of public awareness as they currently are.
But are Americans experiencing "green fatigue"? The ratings for Live Earth, which was billed as a must-see event, were dismal. The American broadcast drew just 2.7 million viewers, making it the least-watched U.S. program on Saturday night. Despite its undeniable entrenchment in pop culture and media, some experts say that the current incarnation of the green movement is just another "We Are the World" moment that consumers and businesses won’t be able to sustain over the long term.
Of course, this perspective is coming from a media outlet (ABC News) for whom the number of viewers are the most significant measure of importance. But that may not be a reliable indicator of how influential the green movement is. There is a wide gulf between public enthusiasm for a green-oriented rally like Live Earth, and public participation in actual green practice in their daily lives. Small steps, in many cases, but a lot of people have started taking at least a few steps to green their lives.
My perspective lies with the building and construction industry. I see increasing numbers of ads and new product announcements from hundreds of manufacturers. I can’t begin to count the number of trade magazine editorials I’ve seen that begin along the lines of this one: "These days, it seems everyone is jumping on the "green" bandwagon — including many companies in [your industry here]." Green awareness has permeated the building industry from top to bottom. And, while not every new building is a new model of sustainability, green building practice is here to stay.
