Supertall buildings call for creative vertical transportation strategies. Hitachi Ltd. and its Hitachi Elevator Co. Ltd. division have annouced that they will build and install 95 elevators—including two that the manufacturer labels as the "world's fastest"—for the Kohn Pedersen Fox-designed Guangzhou CTF Finance Center, which will be 530 meters (1,738 feet) tall.
The two super-speedy units are designed to ascend at rates of up to 1,200 meters per minute, or about 45 mph, with a rated descent speed of 600 meters per minute. The contract also calls for 23 double-deck models running at up to 540 meters per minute, 13 ultra-high-speed units running at up to 600 meters per minute, and an assortment of medium- and low-speed elevators.)
The fastest elevators will travel a shaft height of 440 meters (from the first to the 95th floor) in about 43 seconds. The design includes a permanent magnet synchronous motor, a compact traction machine (achieved through reducing rope diameters, presumably with the aid of advanced materials), high-capacity inverters, braking materials with high heat resistance (withstanding temperatures exceeding 550°F), and a governor that is designed to control various rated speeds during ascent and descent. Active guide rollers will detect warping in the guide rails and lateral vibration caused by wind pressure, helping to ensure a smoother ride. Hitachi has also devised proprietary air pressure adjustment technology intended to help prevent the common sensation of ear blockage caused by pressure changes.
The upscale mixed-use skyscraper will encompass office, hotel, and residential space, and will be the tallest structure in Guangzhou. A 2016 completion date is planned.
Hitachi's experience with vertical transport for tall buildings includes a unit installed in Tokyo's Kasumigaseki Building in 1968—the world's fastest elevator at the time, at 300 meters per minute. The firm operates a 213-meter-tall research tower specifically for elevator development and testing.

U.S Energy Secretary Chu announces $21 Million to improve energy use in commercial buildings
U.S. Energy Secretary Steven Chu announced that 24 projects are receiving a total of $21 million in technical assistance to dramatically reduce the energy used in their commercial buildings. This initiative will connect commercial building owners and operators with multidisciplinary teams including researchers at DOE's National Laboratories and private sector building experts. The teams will design, construct, measure, and test low-energy building plans, and will help accelerate the deployment of cost-effective energy-saving measures in commercial buildings across the United States.

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.

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.
