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!

100% pure solar power from concentrate...

At the Zenith of Solar Energy
Israeli energy startup Zenith Solar is pioneering a "concentrated solar power" method that is up to five times more efficient than standard technology

Rooftops all over Israel look strikingly similar: More than 1 million households in the nation of 7.1 million people have solar panels that produce hot water—a relatively simple technology that gained popularity after the 1973 Arab-Israeli war, when oil prices shot up sharply. As of the early 1990s, all new residential buildings were required by the government to install solar water-heating systems.

Yet despite Israel's sunny climate and early lead in solar heating, it has been slow in adopting more sophisticated solar technologies that produce electricity from sunlight. Now, with oil hovering near $100 a barrel, a local startup hopes to build on the country's early embrace of sun power to carve out a new clean-energy business.

Zenith Solar, based in Nes Ziona near Tel Aviv, is a pioneer in a new type of solar energy that uses mirrors and lenses to focus and intensify the sun's light, producing far more electricity at lower cost. Compared with traditional flat photovoltaic panels made of silicon, this so-called "concentrated solar power" technology has proved in tests to be up to five times more efficient. That puts it on the verge of being competitive with oil and natural gas, even without government subsidies.

A Boost to Israel's Energy Supply
"Our goal is to utilize every suitable roof, backyard, and open space in Israel to turn households, hotels, and factories into net producers of electricity and thermal heat," says Roy Segev, the founder and chief executive of Zenith Solar. Founded in 2006, the startup has raised $5 million from a handful of private investors in Israel and the U.S. Now it's trying to raise an additional $10 million to $15 million to cover the cost of commercializing its technology.

The opportunity is compelling. Israel's National Infrastructure Ministry estimates solar panels for water-heating already satisfy 4% of the country's total energy demand. With technology like Zenith Solar's widely installed, the figure could jump to more than 16%—a big boost for a country now almost totally dependent on imported energy.

Zenith bought the rights to the solar technology from Ben-Gurion University and Germany's Fraunhofer Institute. A joint Israeli-German research team from the two organizations designed a working prototype, which consists of a 10-sq.-meter (107.6-sq.-ft.) dish lined with curved mirrors made from composite materials. The mirrors focus the sun's radiation onto a 100-sq.-centimeter (15.5-sq.-in.) "generator" that converts light to electricity. The generator also gives off intense heat, which is captured via a water-cooling system for residential or industry hot-water uses.

Tested over the past few years at Israel's National Solar Center in the Negev desert, the prototype achieved astounding results: A concentration of solar energy that was more than 1,000 times greater than standard flat panels.

Avoiding Costly Panels
One of the biggest advantages of Zenith Solar's approach, especially in today's market, is its limited use of polysilicon. Skyrocketing global demand for traditional photovoltaic panels has led to a worldwide shortage of the material and lifted prices tenfold in the past four years.
"Photovoltaic material accounts for 80% of the cost of standard systems," says David Faiman, chief scientific officer at Zenith, and a 30-year solar-energy veteran who was part of the development team. "Our technology succeeds in reducing this to less than 10%, while at the same time obtaining very high efficiency."

After further refining the technology, Zenith plans in the coming months to take its first major steps toward commercialization. Two large-scale test installations are planned for this summer at a kibbutz and a factory. The company will put 86 of its 7-meter-high dishes on an acre of land at Kibbutz Yavne to provide the community of 250 families with more than a quarter of their energy needs. The second project will replace fuel oil used to produce heat at a large chemical plant in central Israel.
