Decked out in Dallas: A sprawling rectangular park on top of a major freeway unites an up-and-coming residential neighborhood with the burgeoning Arts District.

 As in many American cities, large highways slice through downtown Dallas. Sidewalks seem intermittent, parking lots abundant, and locals respond with strange looks when asked the best way to walk to a nearby bar or restaurant.

But Dallas is pouring millions of dollars into changing all that. In the past decade, the city has quietly inserted a handful of small green gardens between downtown office towers and condos, providing small reprieves from the expanses of asphalt and concrete. As part of this initiative, over ten years ago, local civic leaders began talking to a team of designers and engineers about coming up with a scheme for uniting the city’s fractured downtown by covering over an existing freeway with a park.

Now, $110 million later, the design team, Jacobs Engineering Group, along with landscape architect The Office of James Burnett, has delivered something radical—5.2 acres of green space laid across an eight-lane highway. The Woodall Rodgers Freeway, oriented northeast-southwest and depressed to minimize traffic noise, ran underneath a number of perpendicular at-grade bridges used as cross streets. The park now fills the gaps between the bridges to create a 1,200-by-200-foot three-block-long deck between Pearl and St. Paul streets. “You only realize you’re near a freeway at the ends of the park,” says principal James Burnett. “You can’t hear the roar of traffic below.”

Rooftop vegetable garden, sculptures add unique touches to Wishard’s replacement

Indiana has never seen a hospital quite like this.

From the spiraling wooden sculpture suspended from the ceiling in the main concourse to the vegetable garden on the roof, the brand-new Eskenazi Hospital keeps you wondering what you will see around the next corner.

The $754 million hospital, which will serve mostly poor and underinsured patients, is nearly ready to open, after four years of planning and construction. The public can tour the hospital from 11 a.m. to 5 p.m. today.

The massive complex, spread out on 37 acres, will replace Wishard Hospital, a deteriorating hodgepodge of buildings, some a century old. On Dec. 7, an army of hospital workers will move patients from the old building to the new one a block away.

The new hospital is the latest addition to Indiana’s hospital construction boom over the last decade, a period in which more than $1 billion in new facilities sprouted up around Central Indiana, from specialty heart clinics to luxurious medical centers in the suburbs.

Each of Indiana’s dozens of hospitals seems to have a distinctive personality, from the luxurious Indiana University Health North Hospital in Carmel, with posh fireplace lounges and cherry wood bassinets, to the kid-friendly Riley Hospital for Children, with its signature red wagons and play rooms.

The feel at Eskenazi Hospital is bright and welcoming. Sunlight pours through windows in every patient room, waiting room and hallway. The public areas are filled with colorful art, from historical oil paintings to whimsical photographs of the city.

The goal, officials say, is to be comforting for people entering the doors for what is often a frightening, high-stress experience.

“We want this to be the most patient-friendly, family-friendly, simple-to-use hospital you can find,” said Matthew R. Gutwein, president and chief executive of Marion County Health and Hospital Corp., which operates the hospital.

Green roof fad comes to town

Imagine flying over a city where the rooftops below are living green, where plants and even vegetable gardens transform the lost spaces on top of buildings. It’s already happening around the world, and Australia is embracing the trend.

In Sydney’s Pyrmont, we’re standing on the rooftop of a heritage-listed building, surrounded by a vast garden sitting in the sky. M Central is an apartment block whose 2005 resurrection as a hip inner-city residence came a century after its construction as a wool store. Landscape architect Daniel Baffsky of 360 Degrees, who designed the 3000sq m communal garden, says the brief was to surprise rather than “have the ubiquitous pool and huge deck”.

Swaths of native foxtail grass lend an almost rural ambience at one end, their furry plumes swaying with the breeze. Bold succulents give textural contrast, while the centrepiece of a small lawn is a magnificent dragon’s blood tree. On the upper level, vine-covered arbours and wide timber boardwalks, shaded by tall tuckeroo trees, flank a covered events area. The sound of water tinkles gently.

The garden is beautiful, but also a social hub for M Central’s 400 residents, offering opportunities for interaction, from barbecues to dog walking.

“There’s no question about the environmental benefits of green roofs but the social benefits are not yet fully explored. Up on the roof everyone is equal,” Baffsky says.

The Empire State Building, an architectural icon in New York City and beyond, just took a giant step forward in its quest to reduce energy consumption. The ‘World’s Most Famous Office Building’ now boasts four green roof systems, totally nearly 10,000 square feet.

For its green roof upgrade, the Empire State Building chose to install the Xero Flor Green Roof System for four rooftop areas: 21st floor east (3,450 square feet), 21st floor west (3,450 square feet), 25th floor northwest (1,000 square feet) and 30th floor west (1,200 square feet). The green roofs on the 21st floor feature rooftop patios with outdoor furniture for the enjoyment of office tenants.

As we’ve reported in the past, the Empire State Building is on a quest to become the most sustainable office building in America. In 2011, the building’s owners announced that they would purchase 100 percent of its power from renewable sources and then embarked on a massive retrofit plan that would earn the Empire State Building LEED Gold.

Nantes accueille le gotha mondial de la végétalisation des bâtiments

par JEAN-PHILIPPE DEFAWE, LeMoniteur.fr, 5 septembre 2013

Après Toronto, Mexico et avant Sydney en 2014, le Congrès mondial de la végétalisation du bâtiment (World Green Infrastructure Congress) se tiendra du 9 au 13 septembre à Nantes, capitale verte de l’Europe.

Avec quelque 1,5 millions de m2 de surfaces végétalisées, la France est le second marché mondial. Il était donc logique que ce congrès, où sont attendus quelques 600 experts du monde entier, se tienne en France. Logique encore que la ville d’accueil soit Nantes, première ville française élue « capitale verte de l’Europe » par la Commission européenne. « Par ailleurs, à Nantes, nous sommes sur un terreau propice à la vegétalisation des bâtiments avec, sur le territoire, le pôle de compétitivité du végétal, Vegépolys, et le cluster de l’éco-construction, Novabuild » justifie François Lassalle, directeur R&D de Sopranature (Soprema) et président de l’Association des toitures et des façades végétales (Adivet), organisateur du congrès.

Marché porteur mais à encadrer

Dans un marché du bâtiment plutôt morose, la végétalisation représente une niche porteuse même si, selon François Lassalle, « le rythme n’est plus aussi soutenu depuis deux-trois ans ». Comme tout marché nouveau, il est encore à encadrer. « Historiquement, les étancheurs sont présents sur ce marché et ils sont rejoints par les entreprises du paysage. Ce croisement entre bâtiment et végétal nécessite le respect d’une réglementation spécifique. Aujourd’hui, il existe des Règles professionnelles conjointes qui doivent être appliquées par tous les acteurs » précise François Lassalle.

« Dans l’avenir, il n’y aura plus d’immeubles tertiaires sans une réflexion préalable spécifique sur la végétalisation »

Alors que se tient à Nantes jusqu’au 13 septembre le Congrès mondial de la végétalisation du bâtiment (World Green Infrastructure Congress), LeMoniteur.fr a interrogé Stéphane Carpier, Directeur technique Développement durable et innovation de Gecina. La foncière a fait depuis quelques années de la végétalisation un élément incontournable de ses projets immobiliers.

Qui est le premier prescripteur de végétalisation sur les projets de Gecina ?

Stéphane Carpier : Gecina s’est lancée dans la végétalisation depuis quelques années déjà. Et tous les cas de figure existent.

A Boulogne-Billancourt par exemple, l’aménageur, la SAEM Val de Seine Aménagement avait expressément requis des toitures végétalisées. On a donc réalisé les premières toitures pour les immeubles Khapa (Foster+Partners, Ateliers 234) et l’Angle (Jean-Paul Viguier) (2008-2009). L’aménageur voulait pour ces bâtiments une sorte de « cinquième façade ». Sur ces toitures, nous avons opté pour une végétalisation « extensive ».

Pour l’immeuble Anthos (Naud et Poux), le végétal est entré dans la conception du bâtiment : la toiture se retourne en façade (mur pignon) et devient un mur végétalisé. La demande de l’aménageur est devenue une idée architecturale. Dans ce cas précis, Gecina a accompagné le projet, à l’époque le plus grand mur végétalisé d’Europe pour un immeuble de bureaux.
