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.

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.
