Freedom Towers aren't free...

Looks like even a bake sale couldn't save the proposed retractable roof for the World Trade Center transit hub, that is, unless you can sell about $40,000,000 worth of snickerdoodles.

Due to ongoing budget woes, it looks as though the Santiago Calatrava-designed structure will need to undergo a post-design facelift. Some might find this sad, but judging by the comments section in the story below, NY locals think the money should obviously be spent elsewhere.

From Gothamist:

Now that everyone knows rebuilding efforts at the World Trade Center are over-budget and very delayed, Port Authority executive director Christopher Ward announced that the Santiago Calatrava-designed transit hub would undergo some changes. Namely, the hub's "wings" will no longer close and open.

CityRoom notes Calatrava had previously said of the hub, "On a beautiful summer day, the building can work not as a greenhouse but as an open space,” on beautiful days and the anniversary of September 11 each year. Now, the Port Authority says, “This is a tough choice, but it is the right choice. It’s reflective of the kinds of choices we simply must make in the coming weeks and months if we are to establish priorities and milestones, to which we can be held accountable.”

Bury me a building with a tree on top...

Wow, what a nice reflection from the windows...

But wait, what's this view? From the inside, that's a...huh!?!?? Is that a window-curtained loading ramp leading to (shudder) yet another friggin' environmentally friendly parking garage?*

Or is it another crazy ski jump from Julien De Smedt, although I doubt that's the case given the unfortunate launch directly into the window. With De Smedt's concepts, however, you never know...

A walkable, livable, enjoyable green roof? Why, I think it is?!?!

I. Want.

OK, this building is old hat to most in the blogosphere, but I couldn't resist a repost.

About two months ago, the first shots of the School of Art, Design & Media, in Nanyang, Singapore came out and were, well, were grainy and pretty blah. Now, however, you can really soak it in...

Designed by CPG Consultants Pte Ltd, the award-winning design is five stories tall and is made entirely of raw, unpainted concrete, cement-sand screeded (screeded is right, yes?) floors, natural timber railings and raw glass.

It begs the question: is it a building with landscape or a landscape with a building?

Light goes in, heat waves stay out. Simple. The internal water feature in the sunken courtyard also provides additional cooling, and affords the possibility of grey water reclamation. It's funny though, all I can think of doing is giving a grandiose speech on one of the palmed islands in the middle while throngs of people lined the upper railings. It would make a CRAZY amphitheater!

Via HERE:

Located at the junction of Nanyang Ave and Nanyang Drive, the new iconic School of Art, Design and Media is situated in a wooded valley right in the heart of the campus.

The design was conceived as 3 intertwining blocks that are apparent natural extensions of the ground. These blocks interweave to enclose a picturesque plaza and landscape. Major spaces such as the Auditorium, Media Studios, library and art galleries surround this outdoor activity node.

Tucked indoors are complementary facilities such as Stop Motion Studio, 3-D Hi-End Computer Graphics Studio, Soundstage, Sound Recording Studios, Audio Visual Editing Suites, Hi-End Digital Post Studio etc.

The highlight of the building is the verdant turfed roof which blends with the ground contour. Apart from its visual impact, the turfed roofscape is a functional space which is easily accessible via sidesteps along the roof edge, thereby allowing the rooftop to be a scenic outdoor communal space. Environmentally, it helps to lower the roof temperature and surrounding areas.

The facade design is a glass curtain wall in neutral grey colour. The remaining parts of the building comprised off-form concrete walls which eschew painting or external rendering works.

The external finish is reserved in its primary condition to maintain its design integrity and naturalness. When night beckons, the building lights up like a beacon that announces its warm presence. The interior lighting streams through the glass curtain walls to render the building a dynamic stage against the backdrop of the external landscape.

*For those of you that don't know this yet, NO parking garage, regardless of LEED points, is environmentally friendly. Urbanize properly and through away the keys!

If there's grass on the roof...

Green roofs, while conceptually and environmentally brilliant, have been plagued with something we are all to familiar with in the Midwest: weight.

In most cases, the majority of existing buildings have the space, but can't afford the load weight. Or often times, the building can afford to hold the roofing system, but would crumble under an additional moisture load. Such added weight is even a problem with on sloping roof systems.

"...green roofs can retain as much as fifty to seventy percent of water that falls onto a roof. Retention varies according to climate. Hutchinson et al reported that a 10 to 12 cm vegetated roof in Portland, Oregon retained 69% of the total rainfall with peak flow reductions of 80% during a 15-month monitoring period. Investigations in East Lansing, Michigan cdompared a gravel roof and a vegetated roof with the mean percent rainfall retention ranging from 48.7% for a gravel roof to 82.8% for a vegetated roof. A similar range was seen on two roofs of different slopes in Goldsboro, North Carolina. Total rainfall retention was 55% for the sloped roof and 63% for the flat roof. Peak flow was reduced by 57% for the sloped roof and 87% for the flat roof." WEBSITE

Poundage-be-damned, green roofing companies are finally beginning to recognize that the existing market is far more available than the future market, and have consequently begun to reduce the load weight in their systems. On company that caught my eye is GreenTech, a Roswell, Georgia based company that specializes in athletic fields, landscpaing systems, golf course systems, and yes, green roof systems.


They're no newcomer to the game, though. In addition to laying claim to New York's largest greenroof and the grass at Wimbledon, GreenTech has found a way to box out the weight and open up the lane to a lighter, newer, more accessible green roof.

***
From their website:

The GreenTech Roof Garden System weighs less than comparable systems for a couple reasons. Forklift and drainage channels displace soil with air. But more importantly, no drainage medium (gravel) is required in the system. This feature works to reduce weight of the system as well as cost of materials and labor.

***

So why is this system able to shed the pounds?

The system has built-in drainage channels that allow the water to flow through the soil into open channels and directly to roof drain outlets. At the same time, each high-density polyethylene module protects the roof surface from root infiltration and damage to the roof membrane. The result is a large planting surface -- with the all-important root depth -- that's more lightweight and flexible than other green roofs. Given the fact that it still discharges the water, some might view the system as less than substantial as other systems, but it needs to be kept in mind that the grey water discharge can be stored for landscape use.

Additionally, the GreenTech allows for almost 40 times the drainage and air flow capacity of conventional drainage systems. Even the drainage channels displace soil, resulting in a 20 to 40% weight reduction. You can even remove the individual sections to replace, repair, or modify the existing system.

But this is what I like most:

The system can be installed in very unlikely places. A back patio loft in the city can suddenly transform into a mini Central Park. You drop the crates, fill with dirt, cover with sod, and finish the edge (simplified, yes, but it is undoubtedly FAR MORE basic than most systems on the market). I like.

I'm going to take a nap in the bath...

How do you turn a dilapidated, run-down lot like this...

...in to a palatial, weather manipulated, sliding roofed, floating walled, mini-house in South London -- that is -- in South London for £210,000 (about $435,000 US)?

With a second mortgage from your father to cover construction costs, and around a bazillion friends to put it all together for you.

A steel-framed house is pretty difficult to construct when you can't afford a crane. But somehow, Monty and Claire made magic, constructing this beautiful dream home out of nothing (how much free pizza and beer do you need to offer to do something like this?!?!).

But really, how cool can this house be? It's sammiched TIGHT between two surrounding brick structures. There's just enough room for one bathroom? They're so close to the neighbors that side view windows wouldn't even work. They must be squeezed at the gills, right?

Well, the bed in the master slides to the side to reveal a bathtub underneath. I'd say that kind of space management can be filed under cool.

In actuality, just about everything in this house can be classified as cool, seeing as it all rotates, slides or spins to add more space.

There's the wall on the master:

The window on the upper mezzanine:

The huge, corner-positioned doors on the side of the dance studio. Yes, a dance studio. FYI: The floor is made out of a Sycamore tree that was cut from the site:

The kitchen cabinets that work at a slant to fit into the odd-shaped nooks and crannies:

And yes, once again, the sliding bed/bath:

Cost efficient solar is coming....

Technologyreview.com has some excellent articles I haven't been able to put down. Everything from biotech to nanotech to energy-related articles, covering the gamut of all that is new and fresh. I HIGHLY suggest this site, including these two articles [1 2] on the greening of concrete. Registration is free, so be sure to check it out.

Solar Power at Half the Cost

A new roof-mounted system that concentrates sunlight could cut the price of photovoltaics.

A new mechanism for focusing light on small areas of photovoltaic material could make solar power in residential and commercial applications cheaper than electricity from the grid in most markets in the next few years. Initial systems, which can be made at half the cost of conventional solar panels, are set to start shipping later this year, says Brad Hines, CTO and founder of Soliant Energy, a startup based in Pasadena, CA, that has developed the new modules.

Cal Academy Cool Roof...

The California Academy of Sciences is currently working on a rebuilding project, with emphasis being placed on the Academy's scientific research and its role in protecting life on earth.


As a natural history museum, the Academy felt it imperative to incorporate as much organic material into the construction and application. The result is one of the coolest green roofs I've seen in a while, planted entirely with wild greenery indigenous to California.

Below are windows on the Morrison Planetarium roof. The windows will let in natural lighting for the aquarium tanks, while the rest of the dome will be a living roof covered in plants. It's not often you get good construction shot, but the Academy is documenting their construction from start to finish. It will be a fun project to keep an eye on.




Even cooler (pardon the pun) is the wall insulation, fabricated using recycled denim blue jeans.

Their involvement is pretty inspiring. Check out their Climate Change Blog if you have time.
