Bahrain WTC, 3 Building Integrated Wind Turbines (S2)

Bahrain_wtc_turbines Recently, in the Week in Review, I blogged about these twin skyscrapers becoming the world’s first commercial development to include large-scale wind turbines in its structure.  As you can see from the pictures, Bahrain WTC towers have three, 32-yard diameter propellers that supply about 11-15 % of the buildings’ energy needs, or about 1100 to 1300 megawatts per year.  The shape of the towers create an airflow tunnel through the buildings for improved energy generation output and each turbine will be suspended on a bridge connecting the buildings.  According to BWTC designer Shaun Killa, solar panels available at the time of construction lost their efficiency due to the high Bahrain temperatures, so wind technology was the better choice for renewable supply.  The turbines will be tested throughout the year and the building will open for business later in 2007. 

The dueling towers are 50 stories each, with 34 floors of office space.  When complete, the entire complex will include a shopping mall, including about 150-200 luxury brand retail sites, and a 5-star Sheraton hotel.  In addition to having SMART features that include high-tech security and IT infrastructure, the building will use an environmentally friendly water cooling system.  Via GE Eco-Business

Sky House, St. Louis Eco-Friendly, Mixed-Use Tower (S2)

Sky House St. Louis

A Fresh Perspective on Urban Living.
  Looks like we’re starting to see teasers for the newest, hottest address in downtown St. Louis: 1400 Washington.  With pre-sales beginning in May 2007, Sky House will be a 22-story building with 166 units of residential and 13,000 sf of street-level retail.  The residential units will be about 850 to 2,230 sf (1-3 bedrooms), with prices starting in the mid-$200,000.  Sky House will be built to LEED standards and have Energy Star stainless steel appliances, a green roof, energy-efficient window systems and balcony doors, and computer-controlled, energy-efficient heating and cooling systems.

Residents will also have access to the Sky Club on the 19th floor.  The Sky Club level includes a pool, hot tub, fitness center, green space, and a dog run.  The importance of the dog run can’t be understated either.  With a dog run, there’s less of a reason for vertical living to be at odds with dog lovers.  The project is developed by Chicago-based Metropolitan Development Enterprises and constructed by RileyWaldrop.  Looking good.

One Bryant Park, Greenest Skyscraper in the World? (S2)

One Bryant Park Rendering

If you’re going to office in what looks to be the greenest skyscraper in the country, you should also have a sustainable business strategy to go along with it.  One Bryant Park, soon to be known as the Bank of America Tower, is the perfect place for a company that just announced a $20B initiative to support environmental lending.  Designed by Cook + Fox Architects and developed by the Durst Organization, One Bryant Park is shooting for LEED Platinum certification.  It’s a 2.1 million sf, 54-story, crystalline office tower located right in midtown Manhattan and is slated for completion in 2008. 

ABC News recently ran an article on some of the more interesting green features of the building.  Interestingly, it will only cost about 1-2% extra (of a total $1.2B) to include all the green additions, but those are expected to be paid for within a 2-4 year window as a result of saved energy expenses.  That’s the business case for green building.  There will be rainwater capture, floor-to-ceiling windows for natural lighting, advanced double wall technology to allow light and block heat, air cleaned of 95% of its particle matter, a floor duct air system controllable in each room or office, three state-of-the-art natural gas fuel cells to create on-site energy, building concrete made of 45% blast furnace slag for stronger construction, and daylight dimming and LED lights for reduced electric usage.  The result:  these green additions have the anticipated benefits of reducing energy consumption by 50%, reducing potable water consumption by 50%, reducing storm water contribution by 95%, and using about 50% recycled materials in construction.  That’s a lighter footprint.

LEED Silver Brickell Financial Centre (S2)

Miami_brickell_financial_centre_1 This is probably the quote of the year for a real estate developer: "I didn’t want a building that in 10 years would have to compete with all the new buildings that are LEED certified."  That’s what Loretta Cockrum, chairman and CEO of Foram Group, said in regards to her new LEED-CS Silver pre-certified project.  The $245 million, 1.5 million sf green project known as Brickell Financial Centre breaks ground in April and is set for completion in fall 2009. The first phase will consist of 600,000 square feet in a 40-story tower, the first floor for lobby and retail space and the second 11 for parking, topped by 28 floors of class-A office space. The second tower, rising 68 stories, will include retail and office space, and a 300-room hotel.  Lead architect RTKL will also have the help of Sasaki for the 30,000 square foot public plaza space, which is supposed to rival New York’s Rockefeller Plaza in scale. 

Green Features:
Like most LEED projects, there’s a slew of green features, so I’m just going to lay some of them out:  low-emissivity window glass covering to allow natural light and block solar heat; chilled water cooling system; low-flow and dual-flush toilets to cut down on potable-water use; storm water cisterns for irrigation; extensive use of low- or no-VOC paints, sealants, and adhesives throughout the building; and special storage facilities for people that bike to work.  As for construction materials, Foram Group will use materials that have a high percentage of recycled content and are sourced within a 500 mile radius.

Chicago's LEED Gold 111 South Wacker (S2)

111 South Wacker 111 South Wacker

Since GreenBuild 2007 will be in Chicago, I wanted to showcase one the many green buildings in Chicago.  In 2005, 111 South Wacker in Chicago, Illinois, received an AIA Design Excellence Award and LEED-CS Gold certification for it’s sustainability achievements.  Designed by Goettsch Partners, the 53-story tower is an incredibly handsome skyscraper.  The transparent base of the tower is particularly interesting with those seemingly dinky pillars holding up the entirety of the building.

Las Vegas' $7B LEED CityCenter Project (S2)

Citycenter_las_vegas

MGM Mirage is developing a 76 acre site between the Bellagio and Monte Carlo called CityCenter.  With about 18 million square feet of new construction (residential, hotel, resort, casino, etc.), CityCenter is being dubbed a "city-within-a-city."  If the project is completed according to LEED standards as planned, City Center will be the largest LEED project in the world.  MGM has lined up some of the world’s best architects for the project, including Pelli Clarke Pelli Architects (61-story resort-casino), Studio Daniel Libeskind (retail + entertainment district), Kohn Pedersen Fox Architects (The Residences at Mandarin Oriental), RV Architecture LLC (Vdara Condo Hotel), Foster and Partners (The Harmon), and Helmut Jahn (The Veers).  Generally speaking, some of the sustainable design benefits include eliminating 48,000 tons of GHG per year, diverting over 80% of construction waste through re-use and recycling, and having improved indoor air quality by using low-VOC and non-toxic materials.   

In 2005, the Nevada Legislature created a statewide tax abatement program that allows LEED building owners to cut property taxes 35-50%.  But that’s not the only reason MGM’s going green on this project.  For most companies, their most expensive asset is people.  Green buildings boost productivity among occupants and providing healthy, well-designed buildings is one way to create value for employees.  CityCenter is slated for completion in November 2009.  Via SunHerald
