Skyscraper Sunday: City of Arabia's "Green" Times Residences

City_of_arabia_times_residences_1 Dubai has money like no other place I’ve ever seen.  They’re working to beat Taipei 101, so they can have the tallest building in the world.  Now, they’ve announced this building called Times Residences, which is aiming to be the only rotating residential structure in the world.  Solar energy will be stored and used to rotate the 80,000 ton, 30-floor structure, 52 degrees every 24 hours.  The project will cost about $109M/Dh400.  Construction is slated to begin June 2007 and end in the first quarter of 2009.  Units will range in size from 1-5 bedrooms and everything will be up-scale + luxurious.  The project was designed by Glenn Howells Architects + Palmer and Turner

In total, there will be 200 residences and everyone will have a 360 degree view due to the solar- powered rotation.  Apparently, one will also be able to tell time by the way the building is lined up, etc.  Although prices for the residences have not been released, sales are expected to begin in March 2007.  What’s more, the developer, Dubai Property Ring, plans to build 23 more rotating towers in each of the world’s time zones.  Whether the building actually gets built is another story.  And although the company states the technology will allow the building to rotate 5 mm/second using a mere 21 electric kettles’ worth of electricity, I’m thinking there must be a better use for all that solar powerWhat do you think?  Via ecofriend.

S2: Charlotte's Green Wachovia Tower by TVS Architects

Wachovia_tower_2_1 Here on Jetson Green, there’s a tradition where I focus on a green skyscraper of notable interest.  This weekly column is called Skyscraper Sunday (click to see archives).  Last week, TVS Architects unveiled the design of what will be Charlotte’s second tallest building, the Wachovia Tower.  It will be 48 stories, 800 feet tall, and have 1.5 million square feet of space, and Wachovia will eat up about half of the building in what seems to be long-term lease commitment.  The word is, owners of the building will be seeking USGBC certification (not sure what level) and will include features such as recycled rainwater and a greenroof, obviously among many other green features.  While there’s not much information on the project just yet, news reports suggest that the price tag will be about $880 million (seem a little high?).  Via Hugg + Forex.

Shizen Urban Design Condominium: A Net Zero Energy Project

Shizen_condo

Every now and then, I find an innovative real estate development group that just knocks my socks off.  After living in Japan for 2 years, I love to hear anything about the place, so you can imagine how cool I think Sakura Urban Concepts is.  Sakura is Japanese for the "cherry blossom tree," which buds in early April and you can see blossoming trees all over Japan for about two weeks.  It’s incredible to see.  This forward-thinking group is behind a new urban design building in Portland called Shizen, which happens to be Japanese for "nature."  Not only is Shizen going to be a net zero energy building, but it’s going to have sophisticated design, sense of community, and sustainable lifestyle written all over it.  Be sure to check out Shizen’s website!

Green Features:
Shizen_kanji This project is funded, in part, by a grant from Portland’s Office of Sustainable Development (via funds from a Green Investment Fund partnership).  First, the site was home to a famous Portland Bakery, the Helen Bernhard Bakery, so Sakura purchased the property and had the house moved down the street.  The house was renovated and looks pretty good.  By moving the house, 200 tons of material was diverted from the landfill.  The condo will have a 23 kW photovoltaic array that generates roughly 1/3 of Shizen’s annual electricity; a biodiesel fueled microturbine will generate the other 2/3 (and enough to heat domestic hot water and space heating); there will be radiant floors in entries and bathrooms; rain that falls on the roof will flow to a 25,000 gallon cistern under the parking level, and that water will be used for toilet and irrigation water; 60% of Shizen’s energy savings will be through its high mass, well insulated envelope and high efficiency lights and appliances; double-glazed, argon-filled, triple coated low-e windows will allow light and block solar gain in the summer; and the roof will be a r-38 insulation. 

Site Specifics:
Shizen will be located on 1706 NE Schuyler (one block north of Broadway/NE 17th).  There will be 7 units, and construction starts in March 2007.  The total building will have about 15,500 square feet (so average of 2,200 square feet per residence?) and the land site is 7,500 square feet.  Not bad at all…Once you go green, you don’t go back.

Skyscraper Sunday: 1800 Larimer LEED Silver Office Tower (Denver)

1800_larimer 1800_larimer_night

Apparently, the mid-1980s was the last time a new high rise office building was built in Denver, Colorado.  We know what happened then and why skyscraper construction halted (hint: construction loans/S+L Crisis); knock on wood…S+L 2.0??  Recently, Westfield Development announced plans to build the most energy efficient high rise in downtown Denver, 1800 Larimer–actually, it’s a $150 million, 22 story, 500,000 square foot, energy-efficient, proposed LEED Silver tower.  Westfield Development President Rich McClintock said, "if it is not a sustainable building, it is outdated."  I couldn’t agree more. 

This LoDo area building was designed by Denver-based RNL Design.  Some of the features include the following:  subfloor air distribution system; 9-foot, 6-inch floor-to-ceiling windows; state-of-the-art health club for tenants; a half-acre terrace parklike environment 20 feet off the ground; tenant controlled temperature system; blue + gray glass facade; trees in the lobby; and a 30-foot high "wall of water" inside the lobby.  I’m excited that new construction is going green, but I will say that Denver is working hard to make the right choices.  This green building is, after all, only a small kog in the greater machine initiated by Denver’s Mayor Hickenlooper called Greenprint Denver

I keep saying this, but the smartest cities are also the greenest:  San Francisco, Portland, Denver, Austin, Chicago, and a trailing Salt Lake City.  The human capital + brain power of these cities is really mind-boggling, so where are you going to live?  Via RMN

UPDATE:  According to the global votes of over 100,000 people, Mayor Hickenlooper was ranked #9 in a survey of best mayors in the world that have made long-lasting contributions to their cities.  Only one other US mayor made the list.

Bioclimatic Design, Menara Mesiniaga + Ken Yeang (S2)

Iaa0291_1

I’ve had people ask me why I haven’t mentioned the Menara Mesiniaga, designed by architect Ken Yeang, in Subang Jaya Selangor, Malaysia.  Well…the building was modern + famous when it was finished in the ’90s, and it’s still modern + famous.  I don’t really know if I can do any justice trying to describe the structure, but I’ll direct you to some more detailed information on the building, in case you’re interested in studying bioclimatic skyscraper design and the like.  The Menara Mesiniaga, often referred to as the IBM building, is owned by Mesiniaga, a Malaysian public company in the IT sector that is somehow connected to IBM.  The 15 floor, 207 foot, intelligent building was finished in 1992, and interestingly, property values of the land around the building have flourished. 

Iaa0296 Excluding the costs of land acquisition, Menara Mesiniaga was constructed at a cost of roughly $8.9 M (USD).  The building design reduces long-term maintenance costs and lowers energy use.  On the north + south facades, curtain wall glazing minimizes solar gain.  On the east + west facades, aluminum fins and louvers provide sun shading.  All the office floor terraces have sliding doors that allow the occupants to control natural ventilation.  The trussed steel + aluminum sunroof also incorporates solar panels that power the building.  Some other features include the skycourt, vertical landscaping, and naturally ventilated core.  The Menara Mesiniaga is the epitome of building design that reflects climate characteristics specific to the location of the building.

Green Office: Get Supplied @ The Green Office

Green_office_screenshot

Officially, this is the third post in a mini-segment here at Jetson Green called the “Green Office.”  First I talked about getting set up with a Think chair, and then I mentioned the Liege Desk.  What next?  How about the thing you use most in the office?  Your supplies.  There’s a great resource for finding sustainable supplies at the comprehensive www.thegreenoffice.com.  The Green Office is “an online retailer of recycled, environmentally friendly, and sustainable business products, school supplies, and paper.”  With regard to green products, it really is the most complete source for supplies (paper, envelopes, calendars, binders, folders, ink, toner, etc.), technology (fax, printer, shredder, telephone, etc.), furniture (shelving, storage, tables, etc.), janitorial supplies (waste containers, cleaning supplies, light bulbs, etc.), and breakroom supplies (cups, plates, etc.). 

Established in 2005 by Alex Szabo, The Green Office itself is committed to setting an example as a sustainable business.  Feel free to skip over to EcoTalk for a 7:50 minute interview with Szabo.  Originally a sustainability consultant, he’s quite the eco-entrepreneur.  In his interview, he talks about how he came upon the idea of starting this business and what he does to continually update the Green Office catalog with nascent product offerings.  See you next time.
