New 'Dorm 4-Airmen' provides higher quality of life for residents, environment

"We knew before we even started building that we wanted it to be LEED-certified," said Mr. Doak. "Because of the stringent standards, we had to start construction with them in mind. "For example, to maintain this accreditation, residents cannot smoke in their rooms," he added. "This also meant that workers couldn't even smoke during construction because smoke has the ability to permeate into the walls and residents years later may be able to still smell that." Two more important parts of the project are both what the infrastructure is made from (autoclaved aerated concrete, also known as AAC) and additional features on the campus-type setting. "The AAC enhances the geothermal and heating, ventilation and air conditioning abilities of the building's design as well as provides a fire-resistant building," said Mr. Doak. "All the features of the dorms and ongoing quality of life projects will result in what is called the 'quad concept,' with the dorm being the main focus of where these Airmen work, play and live." 23rd Wing Public Affairs 4/9/2010 - MOODY AIR FORCE BASE, Ga. -- Regardless of whether an Airman has worked eight or 12 hours that day, they can always look forward to relaxing at their "home."

Article by Christine Park, News Team FRESNO, Calif. (KFSN)

A water-resistant, fire-resistant, termite resistant building material has a lot of builders, firefighters, and homeowners excited, especially those facing fire danger in the Sierra foothills. The destruction of California wildfires is repeated year after year. People lose their homes, everything they own inside, and even their lives, helpless to stop the advancing flames, despite firefighter's best efforts. Laguna Beach Fire Chief, Kris Head said, "The flaming front was similar to placing a giant blowtorch directly onto a house. There wasn't a whole lot that could be done to prevent those homes from burning."

The Road To Code Exceptance

Keith Itzler, P.E
P.E.As Lao-tzu, the Chinese philosopher said, "A journey of a thousand miles begins with a single step."

Drafting and shepherding building code provisions for Autoclaved Aerated Concrete (AAC) through the consensus process has been a long trip. For the researchers and authors involved, it has been a journey that sometimes felt like a thousand-mile forced march. The good news, however, is that they are well along to their destination. The journey that AAC has taken through the code approval process is unique. Code provisions for the classical construction materials such as steel, concrete, and timber are regularly improved, revised and modernized. The introduction of AAC into the model design and building codes is, however, one of the few times, if not the first, that a "new" construction material has been introduced in modern times.

Material stops 2,000-degree fires

By Jim Kavanagh

(CNN) -- An eco-friendly building material might have saved some of the 80 homes destroyed in a recent wildfire in Southern California. But it can't be used there. The masonry material, called autoclaved aerated concrete or AAC, can withstand a 2,000-degree fire for four hours, according to Underwriters Laboratories' test results."I just think the material's awesome. There's nothing like it," said Doug Edwards, an architect whose Edwards Design Group designs and builds green homes in the Scottsdale, Arizona, area. "It's the best building material in the world."

New home building technologies are being developed almost every day, and most builders are accustomed to seeing new tools, techniques and innovation at every trade show and seminar they attend. One revolutionary example is Autoclaved Aerated Concrete, an ultra-light concrete masonry product manufactured by Aercon Corporation in Florida. AAC block weighs as little as one-fifth of ordinary concrete because of its distinct cellular structure featuring millions of tiny pockets of trapped air. This makes AAC appropriate for structural walls, floors and roof decks, creating a strong weather resistant home and providing significant environmental benefits AAC homeowners see a significant reduction of maintenance, insurance and energy costs as well as an increase in overall comfort and safety compared with many other materials. Autoclaved Aerated Concrete has been around for more than 80 years. Invented in Sweden in 1923, the material has been used extensively throughout Europe and Asia. More AAC is produced worldwide than any other.building material except regular concrete.

RESOURCE EFFICIENCY GREEN IS THE RAGE THESE days, but what does it really mean (or matter) to folks who have enough scratch to afford expensive homes? Ego, pure and simple. And perhaps a dash of guilt at the notion of trading youthful idealism for an adulthood of excess. Regardless, the goal of The New American Home throughout the years has been to push the mainstream envelope of performance and efficiency, and this year's version is no exception. In its design, construction, and on-going operation, the house leverages its location and orientation. It's built tight and ventilated right, deploying insulation, high-performance windows, and a zoned approach to indoor air conditioning that not only saves energy and money, but also creates a comfortable environment. As a result, it is the first home certified under the NAHB's new Green Building program scoring method, achieving a gold level. The house also is modeled and monitored by the IBACOS Consortium of the federal Building America program to use 42 percent less energy compared to a similarly sized home in the same climate, including a 62 percent reduction in cooling energy demand. Within a systematic approach to energy and resource efficiency, the project called for autoclaved, aerated concrete block for portions of the first-floor exterior walls (below). It's a lightweight, more workable solution than poured concrete or concrete masonry units, and it achieves an R-8 insulating value prior to rigid foam panels on both sides of the walls. Adding to the overall efficiency are an unvented, insulated attic achieved with R-20 expanded foam insulation on the underside of the roof sheathing (right), a trio of highefficiency heat pumps, and a roofmounted solar thermal collector for tankless water heaters. And in a nice touch, the panels are concealed smartly behind the cupola, out of view from the street.

New University of Indianapolis building uses AERCON Autoclaved Aerated Concrete Construction of the University of Indianapolis' (UIndy) new residence hall is quickly taking shape, incorporating an innovative "green" product made from recycled material that is energy-efficient, fire-resistant and sound-dampening. The $9.8-million East Hall, a four-story structure with 154 single-occupant rooms, multiple lounges and two-story atriums with balconies, is being built with AERCON's Autoclaved Aerated Concrete (AAC) -- a material produced in blocks, lintels and panels. This marks the second time that that AAC is being used to build a facility on the southeast Indianapolis campus. Central Hall was one of the first academic buildings in the nation to use the product. "Our first project was very successful, and the product has lived up to all of our expectations," says Ken Piepenbrink, director of UIndy's physical plant. "It was a very easy decision to select AAC again."

Autoclaved Aerated Concrete (AAC) in Leadership in Energy & Environmental Design

Autoclaved Aerated Concrete (AAC) is an environmentally friendly building material that is used to save energy and enhance the quality of the built environment. AAC has wide usage in Europe, be it for loadbearing, non-loadbearing, interior, exterior and even below grade wall use. Its use has expanded over the past decades to Asia and other markets across the globe.

The environmentally friendly attributes of AAC provide distinctadvantages to building designs when it is used to address “green”or sustainable building concerns. Many of these beneficialattributes are recognized by the LEEDTM Green Building RatingSystem 2.0, which is being used by architects and designers toachieve the environmental benefits and advantages promulgatedby the U.S. Green Building Council (USGBC). State and localgovernments are moving towards requiring that governmentbuildings reduce energy use and implement “green” constructionpractices. Both New York and Oregon provide tax credits forthe construction of sustainable buildings.
