Laurel M. Sheppard is an award-winning writer and editor who has authored several hundred articles related to ceramic materials technology and other engineering fields. She has a B.S. in ceramic engineering from Ohio State University and previously held editorial positions with Ceramic Industry, the American Ceramic Society Bulletin, Advanced Materials and Processes, and Materials Engineering. Her writing and editorial achievements have been recognized by the Society for Technical Communication, American Society of Business Press Editors, and Communications Concepts, Inc. She has also authored over a dozen market reports on various materials technologies and has written articles for IEEE’s Computer Graphics and Applications, Software Strategies, Native Peoples, SWE Magazine, and other publications.
Although there are far more residential fires than those involving non-residential structures, commercial fires still have a hefty price: in 2009 the 103,500 non-residential fires cost 105 lives and over $3 billion in losses, according to the U.S. Fire Administration. Preventive actions are critical to avoid these losses altogether. That’s where a properly designed and installed fire alarm system comes in.
Thermal imaging or infrared thermography is a nondestructive maintenance method that uses infrared cameras to measure the amount of thermal radiation emitted by objects, which is converted to temperature. Normally, to measure the temperature of objects near room temperature requires the detection of radiation in the infrared wavelength range (which is much longer than that of visible light, i.e., approximately 400–700 nanometers). Infrared images are normally colorized so that objects that emit more thermal radiation than others will appear as brighter colors (yellow, red, and white). Cooler objects appear in darker blue, purple, or green colors. Although thermal imaging normally detects only surface temperatures, infrared signatures often indicate temperatures inside structures.
Brownfields are properties that are contaminated with hazardous substances and pollutants that may complicate the properties’ expansion, redevelopment, or reuse. Despite this drawback, brownfield development appears to be increasing. According to the Green Building Market and Impact Report 2010 of the GreenBiz Group, LEED resulted in an estimated 8,800 acres of brownfield reclamation in 2010 vs. 4,800 acres in the previous year. Reclaimed brownfield acres are forecast to grow to over 17,000 acres and 27,000 acres by 2020 and 2030, respectively.
Builders looking for a sustainable, environmentally friendly product may want to consider Accoya® wood, which matches or exceeds the durability and stability of the very best tropical hardwoods. Accoya, made from fast-growing softwoods, was introduced to the North American market in 2008. The process used to make Accoya is called acetylation, which has been studied for over 80 years. Accsys Technologies, the makers of Accoya wood, built its production facility in 2007.

During the Kosovo refugee crisis in 1999, the husband and wife team of architect Cameron Sinclair and journalist Kate Stohr realized that not many architects were involved in rebuilding after the war. So the couple formed Architecture for Humanity, a not-for-profit design services firm originally located in New York City that helps communities to rebuild infrastructure devastated by human or natural catastrophes.
Often dubbed a trenchless technology, pipe bursting involves the replacement of an old pipeline with a same or larger diameter pipe that destroys the original pipe as the new one is installed. The pipe bursting tool, which is pulled through the sewer by a winch or rod located at the upstream manhole, forces its way through existing pipe materials by fragmenting the pipe and compressing the broken pieces into the soil as it progresses.

In November 2010, the U.S. Green Building Council's (USGBC's) LEED 2012 update opened for public comment. Through January 14, 2011, the USGBC will collect these comments, then review them, revise the LEED 2012 updates, and initiate a second round of public comments from July 1, 2011 through August 15, 2011. Balloting by USGBC members for LEED 2012 is scheduled for August 2012, with LEED 2012 set for release on November 7, 2012.
