AEC Pros

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.

It seems paradoxical to integrate a structure intended to immortalize the horrific Holocaust within a public park, a setting for recreation and relaxation. The deliberate juxtaposition of these conflicting elements sets the stage for Santa Monica-based Belzberg Architects to curate a meaningful experience for visitors to the recently opened Los Angeles Museum of the Holocaust (LAMOTH).

The list of street categories is long -- interstates, rural highways, minor arterial roads, collector streets, and neighborhood streets -- and the need to keep them in good repair and of adequate capacity for a seemingly insatiable need is huge. The American Society of Civil Engineers (ASCE) assigned the United States’ Roads Infrastructure a grade of “D-” on their 2009 Report Card for America’s Infrastructure. Why? The report stresses safety (as measured by highway fatalities and injuries), congestion, and road condition. It also seems to be skewed toward the i–nterstate highway system and major urban areas. What about the endless miles of roads that provide a lower level of service?

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.

Buffalo Township’s wastewater treatment plant is located along Buffalo Creek in Pennsylvania, beneath the State Route 28 bridge. This type of wastewater treatment plant is perfect to serve smaller communities. It supports 6,000 people with 3,100 sewer connections to homes and businesses throughout Sarver, Pennsylvania, and the vicinity. It’s an excellent example of an efficient wastewater infrastructure that uses extended aeration to treat raw sewage, without any initial sedimentation.

As LEED celebrates its 10th anniversary, the U.S. Green Building Council (USGBC) reports that one billion square feet of buildings around the world have now been LEED certified. Although that is just a drop in the global bucket, certification has helped to spur green construction; according to the Green Outlook 2011: Green Trends Driving Growth report by McGraw--Hill Construction (MHC), LEED specification is mentioned in 71% of all U.S. projects valued at over $50 million.

This year, the Reina Sofia Museum in Madrid, Spain celebrates its 20th anniversary. Well, sort of. While the Museo Nacional Centro de Arte Reina Sofia officially opened its doors in 1990, the building has been transformed by so many architects over the years that it’s difficult to date.

The project was a seismic retrofit of a 15-story, 750,000 sq. ft. office building constructed in 1991. The steel portion of the project consisted of systematically strengthening the moment connections throughout the building and installing over 200 dampers without interrupting the operation of the tenants. The contract dictated that the work would start in the basement, progress through the ground floor and the parking garage (floors 2-5), and then continue through the occupied office floors (6-15). The contractor could only occupy three half-floors at any one time. Although my team was extremely experienced, with over 20 years of seismic experience and over 50 years of steel work experience, this project provided us with some significant lessons to take with us to our next project.

Located in Freeport, Pennsylvania, about a 30 minute drive north of Pittsburgh, Buffalo Township’s water treatment plant produces over 700,000 gallons of fresh water daily. The plant provides drinking water to over 5,000 residents in Buffalo Township and Freeport Borough. It is also the fresh water supplier for the Municipal Authority of South Buffalo Township. Join Buildipedia for a photo tour of Buffalo Township’s water treatment plant, as we trace the flow of water from the Allegheny River to its distribution throughout the utility.

During times of economic uncertainty, we need to expect more out of every investment. Whether as a homeowner making small improvements or as a business owner making multimillion dollar improvements, we must make highly informed decisions to capitalize on the investment. Buildipedia's new series on ROI (return on investment) driven products looks to provide the information to help make these decisions. This step-by-step approach to a product's cost as well as its ROI will aid both new builds and retrofits. Here we focus on windows and toilets, both of which play big roles in energy and water usage in our buildings and provide different opportunities to reduce expenses.

Perhaps no building type has changed more in the past generation than the university library. Enormous book collections, once the organizing feature of these buildings, have lost their prominence as scholastic resources. Today’s college students, having grown up using the Internet, have little patience for a warren of "stacks" and laborious searches through printed materials. Therefore, a building prototype that was traditional, monumental, and static has given way to a new, more fluid style.The dynamic form created by Zaha Hadid to house the new Library and Learning Center for the University of Economics and Business in Vienna, Austria, makes a definitive statement regarding the contemporary function of a scholarly library.
