The world's first net-zero energy skyscraper rises in Indonesia

The world's first net-zero energy skyscraper rises in Indonesia | Développement durable et efficacité énergétique | Scoop.it
The Pertamina Energy Tower's curved façade is precisely calibrated for Jakarta's proximity to the equator to mitigate solar heat gain year-round.

 

The world's first net-zero energy skyscraper soon will grace the center of Jakarta, Indonesia — the Pertamina Energy Tower. When it's finished in 2019, it will be 99 stories high and serve as the headquarters of the national energy company. In addition to the 20,000 people who will work there, it will be the centerpiece of a campus that has a mosque, a sports center and a 2,000-seat auditorium for the performing arts.

Shaped like a funnel, the top of the tower opens at the top, capturing wind and sucking it inside to run a series of vertical wind turbines that provide 25 percent of the building's electricity.

The building is designed to be a symbol of Indonesia's commitment to sustainable development. Find more details at the link.

Au centre de Jakarta, ce bâtiment sera le symbole de l'engagement de l'Indonésie pour le développement durable.

Programme ambitieux dans le design comme dans les technologies.

Tracy Galvin's curator insight, April 24, 11:32 AM

Hopefully, this will be the wave of the future. The building is designed specifically for the place it is going to sit and how it can gain the most energy from the natural resources available. They are taking advantage of the sunlight and geothermal sources of energy that do not pollute the environment and never run out.

Pittsburgh's "breathing" building by Gensler aims to be the world's greenest skyscraper

Pittsburgh's "breathing" building by Gensler aims to be the world's greenest skyscraper | Développement durable et efficacité énergétique | Scoop.it

The PNC Financial Services Group hopes to exceed LEED Platinum requirements while promoting a healthy workplace with a recent development – the Tower at PNC Plaza. Located in downtown Pittsburgh, the building will be 800,00 sq.ft (74,322 sq.mt) with a construction budget of approximately US $240 million.


The "breathing" design created by architecture firm Gensler moves away from the traditional closed air-conditioned environment and has the lofty aim of becoming the greenest skyscraper in the world.


Employees in the 33 floor glass tower will access daylight and fresh air. The PNC Tower design recognizes that the Pittsburgh climate can provide increased levels of natural light onto the floorspace along with improved regulation of temperatures for much of the year without using traditional, energy-intensive HVAC systems. The Tower hopes to achieve this with a double-skin facade of two panes of glass separated by an enclosed cavity, allowing external air inside. The facade features operable doors and windows that admit fresh air into the building during optimal conditions, while a solar chimney is another passive system- it pulls air in through the open windows, the air then travels across the floors, is heated and exhaled through the roof shaft.


The Tower will consume less than 50 percent of the energy a typical office building uses and will save PNC at least 30 percent on its energy costs...

Tall buildings have been historically less efficient than smaller squarer buildings to operate, but now with new technologies we are seeing rapid improvements in the taller buildings and FINALLY we are seeing things like operable ventilation once again.

Society for College and University Planning (SCUP)'s curator insight, February 1, 2013 9:25 AM

SCUP–49, the Society for College and University Planning's 49th annual conference, will be held in Pittsburgh in July 2014.

Wooden Skyscrapers: A New Level of Sustainability?

Wooden Skyscrapers: A New Level of Sustainability? | Développement durable et efficacité énergétique | Scoop.it

A new breed of high-rise architecture is in the process of being born, thanks to the collaborative efforts of modern design pioneers. Envisioned as the best sustainable option for meeting world housing demands and decreasing global carbon emissions, wooden mega-structures are now one step closer to becoming a reality.


“Big Wood,” a conceptual project to the eVolo 2013 Skyscraper Competition, builds on the premise that wood, when harvested responsibly, is one of the best tools architects and engineers have for reducing greenhouse gas emissions and creating healthy communities. Aspiring to become one of the greenest skyscrapers in the world, Big Wood challenges the way we build our cities and promotes timber as a reliable platform to support tomorrow’s office and residential towers...

Whoa..Chicago!

Fascinating place. Must of been a lot of wood to be created.

Bubba Muntzer's comment, May 13, 2013 11:44 AM
It takes around 30 years for a seedling to grow into the kind of wood that can be used in construction. A little maintenance is required during that period. Meanwhile it's soaking up CO2 and making oxygen. The only industrial processes required are to cut it down and cut it into boards and 2 x 4s. If you stagger your planting you have an endless supply.
