At the end of each year, Environmental Design + Construction magazine reviews products mentioned in its New+Notable and Products Focus sections. The magazine next examines these products for the fifteen that received the most reader requests. ED+C's 2009 Top Products contains a number of entries designed to save water or manage water. You've probably seen some of these products already, whether on BuildingGreen's Top-10 Green Building Products list or in our green materials archives. If not, check these out:
Last week at Greenbuild 2009, Perkins + Will unveiled its new Precautionary List, which tracks 25 of the most common dangerous chemicals found in commonly used building materials. The list provides an explanation of the properties of the chemicals with suggested alternatives. Some of the chemicals on the list include: arsenic, lead, urea formaldehyde, and cadmium, just to name a few.
Yes, it's that time again. For the eighth year in a row, BuildingGreen has just announced their list of Top-10 Green Building Products. BuildingGreen sifts the products from new additions to the GreenSpec Directory, a print and online guide that organizes green products according to LEED credits, as well as from coverage in Environmental Building News. The GreenSpec Directory has over 2,100 products, and these ten are some of the best of what's been added to the directory. Any favorites among the group?
We first saw this 3form material, Koda XT, with the wavy transit shelters in San Francisco. Designed by Lundberg Design, the colorful transit shelters use a custom configuration of Koda XT, a material made of 40% pre-consumer recycled content. 3form says Koda XT is the only architectural polycarbonate material available to use towards LEED MR 4.1 for recycled content.
Stormwater design and control is a huge aspect of green building, especially with LEED credits provided for reducing impervious cover, increasing on-site filtration, and reducing pollution from stormwater runoff and eliminating contaminants. We've mentioned a company previously makes recycled content pavers, Vast Pavers, but I thought I would also mention another company that's been making news in the industry, Xeripave. Xeripave makes permeable pavers in various colors that have a flow through rate of up to 1.5 gallons per second per square foot. Watch how the paver works:
The photograph above may not be what you would expect. The outdoor bench in this detail is not made from an unsustainably harvested tropical hardwood. The wood itself is actually maple, a widely available species that can be farmed and harvested without ripping up acres of rainforest. But maple and many other similar woods are too susceptible to decay and rot when used unprotected outdoors. The usual alternative has been treatment with chemical pressure treatment. Now, through a method called kebonization, a Norwegian company, Kebony ASA, treats soft woods in a non-toxic process that allows readily available woods to be used for outdoor uses.
