Skyscraper Sunday: Hearst Tower Goes LEED Gold

Hearst_diagrid_structure The handsome Hearst Tower skyscraper achieved LEED Gold accreditation from the USGBC–it’s the first to be recognized as such in New York City.  The building architect is the famous Norman Foster, and this is the third time for Jetson Green to feature one of his buildings (30 St Mary Axe + WTC 200 Greenwich).  Norman Foster is literally one of the leading architects in the modern/contemporary + green building field.  This building is particularly bold for its environmental mission: it used 80% recycled steel and will consume 25% less energy than its skyscraper counterparts. 

Green Features:
The green features of Hearst Tower reflect the environmental commitment and vision of Hearst Corporation–a leading corporation with interests in magazines (O, The Oprah Magazine, Popular Mechanics, Cosmopolitan, + Esquire), newspapers (San Francisco Chronicle, Seattle Post-Intelligencer), broadcasting, entertainment television (ESPN, ESPN2, Lifetime, A&E, + The History Channel), and interactive media (broadcast dot com, iVillage, XM Satellite Radio).  We are talking about a huge company taking a pro-active step to provide high-caliber, environmentally-friendly working spaces. 

  • About 85% of the original structure was recycled for future buildingHearst_at_dusk
  • The "diagrid" system (diagonal + grid) eliminates the need for verticle steel beams, which provides structural efficiency and greater use of natural light
  • Using the diagrid system required 20% less steel (a 2,000 ton savings in steel)
  • Foreign-sourced materials accounted for less than 10% of the total cost of construction
  • Low-E coated glass on the exterior of the building allow natural light into the building sans heat
  • Internal light sensors control the balance of artificial and natural light
  • Activity sensors adjust the system and turn off lights and computers when systems aren’t in use
  • The roof collects rainwater and reduces the amount of rainwater that dumps into NYC’s sewer system by 25%
  • A 14,000 gallon water reclamation tank in the basement provides 50% of the buildings water needs
  • Harvested water is used for the "Icefall"–a 3-story sculpted water feature (also the nation’s largest sustainable water feature) that will humidify and cool the atrium
  • Walls were painted with low-VOC paint, workstations were built without formaldehyde, and concrete surfaces were finished with low toxicity sealants
  • Floors and ceiling tiles are manufactured with recycled content

Ketchum, Idaho Contemporary Residence with a Lighter Shade of Green

Snow_image There was a home in Architectural Digest that really caught my eye.  Maybe it’s because the Roger Wade images perfectly captured how the house blends into the hilly landscape of Ketchum, Idaho.  I don’t know…maybe I was just intrigued by the hoops the architect Jim McLaughlin had to go through just to get the darn thing built.  The architect had height restrictions to deal with and still managed to squeeze in 9,000 square feet of space.  The interesting thing about this house is that it has a contempory-interior, modern-exterior, traditional home-type feel to it.  I mean, it doesn’t look like one of the prefabs I like to talk about, but it’s extremely contemporary.

They excavated 25 feet into the hill and built from within the rock to make the house seem like it’s flowing from the rocks.  The architect designed the home to use local Montana stone on the facade and accented that with reclaimed beams inside.  With all the windows, the builder (Gary Storey) and architect found a way to incorporate motorized sunshades the shoot up from the floor to the top of the windows.  What that does, in turn, is blur the boundaries between the interior and exterior and provide an effective method to maximize the balance between natural light and shading.

While I know some of my devoted readers will scream because this place has a 9,000 sq.ft. footprint and doesn’t really use alternative energy, I think the house illustrates a lighter shade of green.  The place looks good and uses local materials and reclaimed wood.  That’s a start. 

As far as the interior is concerned, the kitchen has zinc counters and wenge-wood cabinets with white-bronze inlay.  Designed by Libby Brost, a former chef and restaurant owner, she recently sold her restaurant to concentrate on design.  She designed the kitchen so that it didn’t necessarily look like a full-blown kitchen.  It’s there, but it blends into the other room.  And that goes the same with the other rooms.  I think it’s a handsome place.

Design: e2 "Grey to Green" — Rethinking American Construction Waste

Introducing "Grey to Green."  It’s a snippet from the Design: e2 series narrated by Brad Pitt.  We need a paradigm shift in the methods we employ to construct US buildings!  Watch this video on construction waste and think about the status quo.  Did you know that American buildings account for 10% of the world’s energy use?  They do.

Design_e2_logo_1 Part of the draw to modern prefab, for me, is that it presents the opportunity to efficiently, and relatively wastelessly, produce attractive, sustainable living spaces.  That’s very important.  Technology and process innovation can help us quit wasting energy, supplies, and materials, etc.  Construction waste is not only damaging the earth, but by continuing on the current path, we’re just throwing money away (both at purchase and trash points).  We need to understand the issues and find creative, innovative, positive, and attractive solutions. 

This video is extremely informative, and you can order the PBS series DVD from their website for $29.95.  The DVD includes all six episodes (The Green Apple, Green for All, The Green Machine, Gray to Green, China: From Red to Green, + Deeper Shades of Green).  I can’t catch it on TV, so I’m going to go ahead and purchase it.  Really, watch the video and you’ll realize why it looks to be a good series.

Northern New Jersey Attached Residence + Spa + Tennis Court Gets Sustainable

Night_court_exteriorTranslucent, shimmery, membraneous, sustainable. When I saw the look of this tennis court in Architectural Digest, I was blown away…and I don’t even play tennis.  (By the way, October 2006 AD is chock full of modern + sustainable architecture!)  At Jetson Green, I talk a ton about residential green spaces or commercial skyscrapers, etc., but I haven’t spent that much time on sustainable structures crafted specifically for sport, hobby, or play.  Architect Robert Rhodes put together a striking, modern tennis court/spa/attached residence for a client that I need to share.

Just a short skip down a slate trail from the main residence is this tennis court embedded in a New York investment banker’s 8 acre, well-wooded property.  The goal for the architect was to conform to the local zoning requirements, apply sustainable building principles, and keep consistent with the surrounding flora.  I think they did a phenomenal job. 

Green Features:
The client + architect wanted the court to "look like trees."  Here’s what they did to keep it green + sustainable.  First, they built the tennis court into the ground so that the structure wouldn’t stick out.  The same principle applied when they decided to use tennis-green, transparent polycarbonate-panels; the panels allow enough light inside for day use and keep out the harsh sunlight for cooling purposes.  Second, the court’s energy is supplied by two geothermal wells.  And third, they used an ipe deck (economic + ecologic) between the attached residence and court.  Also note, there is a subterranean spa below the deck that connects the guesthouse and court.   Investment banker Cribs anyone?

Court_image_1 Spa_court_image Attached_residence

The laminated-wood beams stretch vertically, almost as if they are the actual trees that surround the court.  Aesthetically, the panel and beam design finishes out the structure so that it blends and matches the surrounding environment.  And while I think this investment banker won’t be able to practice his lob, he surely will be able to relax, spa, and play tennis in a court fit for English royalty!

There's a New Prefab in Town: Michelle Kaufmann Designs + mkSolaire

Mksolaire If you haven’t noticed, there’s a new prefab in town.  But if you’ve been following the modern prefab movement, you’ll recognize this newest installment comes from an experienced architect:  Michelle Kaufann Designs.  MKD is behind the glidehouse and sunset breezehouse prefabs that have become the talk in modern + sustainable building circles.  But these aren’t just prefab concepts or designs.  Recently, MKD finished building the first U.S. factory dedicated to sustainable, modular custom homes (www.mkConstructs.com).  This Washington (state) factory is wholly-owned by MKD and will serve California, Washington, Oregon, and Hawaii. 

Solaire_interior The mkSolaire is an open, loft-like home designed for healthy, green living in the urban context.  The architecturally designed roof and windows allow a perfect mixture of air and light to enter the home.  Initial design to completion lead time is roughly 8-14 months, which varies depending on a variety of factors specific to your design and location.  Some of the things that will be available include solar panel roofing, geothermal system, wind generator system, hybrid system, icynene insulation, bamboo or reclaimed wood flooring, recycled paper countertops, recycled glass countertops, on-demand water heaters, water-saving dual-flush toilets, non-toxic paints, and formaldehyde-free cabinetry, etc. 

Solaire_roofSolaire_18  Solaire_17

Because the mkSolaire is built from a modular system, there are endless possibilities as far as layouts and floorplans.  The website has 5+ floorplan options, but it looks like those can be further customized.  And if you’re really interested in taking the plunge, MKD has tried to take the sting out of prefab costing by explaining how it all works.  This stuff isn’t cheap:  factory costs ($150-175 square foot), transportation + installation ($3,000 – $8,000 per module), site costs (depends on location), and miscellaneous costs (permit fees, architectural and engineering fees, sales tax for some states, appliance costs, add-on costs, etc.).  That said, homes do come with high-end Kohler  and Hansgrohe fixtures, Anderson windows + doors, and slate-tile flooring.

I could go on and on, so feel free to visit their site and see if this looks like something you’re interested in.  As far as modern + green custom architectural design is concerned, this is about as good an option as they come.  Source via Linton + Yahoo Finance

Skyscraper Sunday: SOM, Green Skycraper Firm of the Year

Jinao_tower_nanjing_1There’s just no stopping Skidmore, Owings + Merrill.  They are the (as nominated by Jetson Green) Green Skyscraper Firm of the Year.  I blogged about them in regards to the zero energy Pearl River Tower, which absolutely blows me away.  Have you seen the thing?  I also blogged about them on 9/11 because they designed the green Freedom Tower, which is going to be an architectural beacon of freedom and innovation for decades in the future.  When it comes to sustainability and architectural excellence in skyscapers, SOM is the number one firm.  That’s hands down. 

SOM has an enormous portfolio of work in China and they are working on over 15 skyscraper projects there right now.  Interestingly, it’s easier to be innovative in China because the climate lends itself to such behavior.  Firms in the US are reluctant to take on commercial/security risk.  They don’t want to tick off neighbors or trade unions either.  China on the other hand wants to push the envelope.  They have cheap materials and a desire to build green structures.  They are a command economy, so there’s not much public outcry, even if the building is outlandish.  Plus, global recognition helps their situation.  I get heaps of search queries on my blog everyday for a post I did on the Pearl River Tower–that’s global recognition.   

Nanjing_jinling_hotel_1 Nanjing_greenland Shenzhen_avic_plaza

I’ve included some pictures of buildings that SOM has designed for construction in China.  There’s too much to say about each, but one thing should be noted, however:  these buildings are all going to be done in 2007-2008.  There’s a quick turnaround time in China–they have the attitude to get things done.  Notice the delay for buildings like this in the United States and query whether that has anything to do with (in comparison) innovation, politics, determination, or drive.

Nanjing Greenland will have irregularly-spaced slots for green space that "march vertically up the facade."  Jinao Tower will be built with less steel than a traditional skyscraper.  It will be built around a diagonal grid bracing system (similar to the one used for Hearst Tower of New York).  Jinao Tower also features a double-skinned surface for solar shading and insulation.  Each SOM buildling is chock full of innovation.
