On-Site Reuse of Concrete From Demolition Projects for New Construction Projects– Rich Jones, John Gottleib, Richard Scheidet, and Peter D. Pohlot During 2006, Brookhaven National Laboratory (BNL) demolished 10 buildings/structures while constructing 2 new facilities (the Research Support Building and the Center for Functional Nanomaterials). This paper details how the concrete from the demolition projects was re-used as part of the new construction projects at a significant cost savings to the Laboratory. BNL has an authorization from the New York Department of Environmental Conservation to operate what’s known as the “Borrow Pit”. The Borrow Pit is an area where sand was mined for a Laboratory project, leaving a large void space in the firebreak area south of the Laboratory. The authorization allows BNL to fill the void space with Construction & Demolition (C&D) debris. Approximately 4-years ago when the Borrow Pit was close to capacity, a decision was made to bring in a concrete crusher and mine the Pit to generate Recycled Concrete Aggregate (RCA) to be used around the Laboratory’s firebreak road system to stabilize the roadways and as new road base for new parking areas and roads. Prior to this, the Laboratory purchased virgin crushed blue stone to stabilize the firebreaks. During 2006, numerous older structures (pre-1950) were demolished due to issues such as advanced stages of deterioration, energy inefficiency, and repairs not being cost effective. The following table details the buildings that were demolished and the respective amounts of material (in tons) that were recycled (concrete and metals) and the remains that were sent off-site to a C&D management facility (i.e., roofing shingles, lumber, siding, etc…) Building Concrete Metals C&D 86 300 3 260 326 5 0 18 400 parking lot 2000 0 0 422 80 0 160 445 2600 2 12 527 0 0 150 707/707A 220 20 0 707B 32 0 0 715 6 0 6 753 12 0 12 750 CT & Tank Storage 250 10 0 Totals (tons) 5505 35 618 These demolition projects generated over 5500 tons concrete, which was crushed at the Borrow Pit and recycled as RCA (see Figures 1 and 2). The majority of this RCA (approximately 4800 tons) was used as the predominant base for the parking lots of the two new construction projects – the Research Support Building and the Center for Page 2 Functional Nanomaterials (see Figures 3 and 4). The remainder was used for position: absolu

Inhabitat May 8, 2007 iSAVE Water-Saving Faucets by Jorge Whether you live in a drought-plagued region or you’re just trying to be efficient, there are a myriad reasons to conserve water. That’s why we love the iSAVE faucet by Reamon Yu- a design so clever and efficient that it was recently chosen as a runner-up in the Metropolis Magazine Next Generation awards. The gadget easily attaches to your sink or showerhead to provide a digital readout of the amount of water that was being used in a shower. What’s more, iSAVE is powered by energy generated by the water passing through it using a small turbine embedded the device.

Current applications include both interior and exterior walls, as a canopy roof, and a countertop. As a simple exterior wall, the LEED applications are obvious, as the translucency of the IllumaWALL system allows diffused daylight into any space while minimizing both heat gain and glare. Architectural Record and Buildings Magazine sung the praises of IllumaWall this past December, including IllumaWALL on their list of top products of 2006.

Made of translucent polycarbonate panels and custom-programmable LED’s, the applications for IllumaWALL seem both endless and endlessly entertaining. The array of Duo-Gard’s IllumaWALL’s colorful lighting schemes is made possible by the programming capabilities of LED’s, whose versatile nature can transform the wall from steady ambient glow to a light show of pulsating colors in seconds.

The recent fad of using wood cladding, louvers, and filigree as sun shading for buildings has left architects scrambling for a substitute material that’s beautiful, structurally stable, durable, and sustainable - - - oh, and reasonably priced. Two manufacturers, Kliptech & Richlite have brought to market resin-impregnated paper building products that can not only be used for a resilient building skin, but have also been used as countertops, cutting boards, and skateboard ramps. The two products vary in their aesthetic quality, environmental claims, and price. We’ve also recently covered ShetkaStone which is similar in composition, but has a more terrazo like appearance. If you’re looking for an alternative to teak, redwood, cedar or Parklex, read on…. Both products exhibit superior durability and are available in thicknesses from ¼” to +1″. These “resin paperboards” can be worked by standard wood workers’ tools, but because they produce very fine particulate dust, respiratory protection is highly recommended.
