Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) have developed a way for 3D printed metals to be produced with an unprecedented degree of precision, Archdaily reports.
This development can help with the customization of the smallest components in buildings and carefully engineer details of larger ones.
The precision comes from the new technique of adding a process in which successive layers of material are laid down with computer control and fused to create an object in a wide range of shapes.
Advanced technology has also led to an increase in resolution, enabling the creation of smaller parts with smoother surfaces. The ORNL explained in a statement:"The researchers demonstrated the method using an ARCAM electron beam melting system (EBM), in which successive layers of a metal powder are fused together by an electron beam into a three-dimensional product. By manipulating the process to precisely manage the solidification on a microscopic scale, the researchers demonstrated 3-dimensional control of the microstructure, or crystallographic texture, of a nickel-based part during formation."

Data Centers: Keeping Energy, Security in Check
Power consumption for data centers doubled from 2000 and 2006, and it is anticipated to double again by 2011, making these mission-critical facilities the nation’s largest commercial user of electric power. Major technology companies, notably Hewlett-Packard, Cisco Systems, and International Business Machines, are investing heavily in new data centers. HP, which acquired technology services provider EDS in 2008, announced in June that it would be closing many of its older data centers and would be building new, more highly optimized centers around the world.

New Design Concepts for Elementary and Secondary Schools
Hard hit by the economy, new construction in the K-12 sector has slowed considerably over the past year. Yet innovation has continued, along with renovations and expansions. Today, Building Teams are showing a keener focus on sustainable design, as well as ways to improve indoor environmental quality (IEQ), daylighting, and low-maintenance finishes such as flooring.

Renovating for Sustainability
Motivated by the prospect of increased property values, reduced utility bills, and an interest in jumping on the sustainability bandwagon, a noted upturn in green building upgrades is helping designers and real estate developers stay busy while waiting for the economy to recover. In fact, many of the larger property management outfits have set up teams to undertake projects seeking LEED for Existing Buildings: Operations & Maintenance (LEED-EBOM, also referred to as LEED-EB), a certification by the U.S. Green Building Council.

Honeywell's School Energy and Environment Survey: 68% of districts delayed or eliminated improvements because of economy
Results of Honeywell's second annual “School Energy and Environment Survey” reveal that almost 90% of school leaders see a direct link between the quality and performance of school facilities, and student achievement. However, districts face several obstacles when it comes to keeping their buildings up to date and well maintained. For example, 68% of school districts have either delayed or eliminated building improvements in response to the economic downturn.

Architecture Billings Index: inquiries for new projects remain extremely high
The new projects inquiry index was 61.7, down slightly from a nearly three-year high mark of 62.3 in September, according to the Architecture Billings Index (ABI). However, the ABI dropped nearly two points in October; the October ABI score was 48.7, down from a reading of 50.4 the previous month. The ABI reflects the approximate nine to 12 month lag time between architecture billings and construction spending.

Brazil Olympics spurring green construction
Brazil's green building industry will expand in the coming years, spurred by construction of low-impact venues being built for the 2016 Olympics. The International Olympic Committee requires arenas built for the 2016 games in Rio de Janeiro meet international standards for low-carbon emissions and energy efficiency. This has boosted local interest in developing real estate with lower environmental impact than existing buildings. The timing couldn’t be better: the Brazilian government is just beginning its long-term infrastructure expansion program.

Calculating office building performance? Yep, there’s an app for that
123 Zero build is a free tool for calculating the performance of a market-ready carbon-neutral office building design. The app estimates the discounted payback for constructing a zero emissions office building in any U.S. location, including the investment needed for photovoltaics to offset annual carbon emissions, payback calculations, estimated first costs for a highly energy efficient building, photovoltaic costs, discount rates, and user-specified fuel escalation rates.
