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...

Norm Miller's curator insight, January 9, 2013 12:07 PM

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.

Energy Land(ing)-scape | Calderara di Reno Italy

This project seeks to find a effective balance between two principal necessities: to redevelop and revitalize the area, with a strong ecological impact on surrounding territories. The solution was to transform the area into a ZEA: Zero Emission Area.

A ZEA promotes the area and seeks for investments and a new economical initiatives to transform an area into a environmental zone. The project consists of a solar roof installed over the existing warehouse’s roofs and over the outdoor areas, including parking, producing clean energy, reduces emissions, collects water and gives a new image of the region to all people that are taking off or landing in the close Airport of Bologna.

The project seeks to give new life to this area from an economic point of view, as well as to demonstrate how development can have a positive ecological impact.

Arboleda, an urban mixed-use community now under development in Monterrey, Mexico, is designed by Pelli Clarke Pelli Architects of New Haven, Conn., in collaboration with landscape design firm Office of James Burnett.

The project incorporates principles of sustainable design and green building and will be compliant with the LEED for Neighborhood Development standard. The development is designed by Pelli Clarke Pelli Architects in collaboration with landscape design firm Office of James Burnett on behalf of Mexican developer One Development Group (ODG).

According to Pelli Clarke Pelli, the 26-acre Arboleda site will include residential and commercial development centered around a large central park and incorporating generous green space and native plantings, and all buildings will be LEED certified...

Can the World Really Afford More Empty Cities?

Can the World Really Afford More Empty Cities? | Développement durable et efficacité énergétique | Scoop.it
Architecture that does not have a function, is not appreciated or that stands unused has no place in a world that consumes as many naturally resources as ours.

The global building industry caters to the needs of billions, but it also is the highest consumer of these resources, meaning that there must be a level of responsibility in play that restricts unnecessary works at all costs.
However, an increasing number of urban development projects are being undertaken that are unused and unnecessary. These ‘ghost towns’ stand as an outdated and regressive waste in the meantime, although they are often justified as a long-term development goal...

Cities: Drivers of Sustainable Human Development & Prosperity

Cities: Drivers of Sustainable Human Development & Prosperity | Développement durable et efficacité énergétique | Scoop.it
As we plan for the future of our planet, it is imperative that we consider the effects of development on both the environment and human populations. A city is only truly sustainable if it uses natural resources efficiently while still fully meeting the needs of its inhabitants and a decent standard of living.

Recently, the UN Human Settlements Program (UN-HABITAT) launched its “State of the World’s Cities Report 2012/2013” which addresses the prosperity of cities. According to the report, the first step to achieving prosperity is to define the goal: What does prosperity mean in 2012? This is a difficult question to answer given the vast disparity of living conditions throughout the world. Additionally, it is imperative that the definition of prosperity today consider the needs of future generations. To this end, UN-Habitat developed a “City Prosperity Index,” which translates the five dimensions of prosperity identified by UN-Habitiat—productivity, infrastructure development, quality of life, equity and social inclusion, environmental sustainability—into measurable indicators (see page 15 of the report).


This definition of the prosperous city is consistent with the principles of a smart, sustainable and just city... further reading at the article link

Achieving sustainable, inclusive cities requires better planning - UN News Centre

Achieving sustainable, inclusive cities requires better planning - UN News Centre | Développement durable et efficacité énergétique | Scoop.it

Top United Nations officials have underscored the need to better plan the world’s urban areas, where half of the global population currently resides, to turn the ideal of sustainable and inclusive cities into reality.

“In little more than a generation, two thirds of the global population will be urban. As the proportion of humanity living in the urban environment grows, so too does the need to strengthen the urban focus of our efforts to reduce global poverty and promote sustainable development,” said Secretary-General Ban Ki-moon.

In his message for World Habitat Day, Mr. Ban noted that better planned and better functioning cities can help ensure that everyone who lives there has adequate shelter, water, sanitation, health and other basic services. He also noted they promote education and job prospects, energy-efficient buildings and public transport systems, and a feeling of inclusiveness for inhabitants.

According to the UN Human Settlements Programme (UN-Habitat), the main challenges confronting cities and towns all over the world today include unemployment, especially among youth; social and economic inequalities; and unsustainable energy consumption patterns.

Urban areas are also responsible for most of the world’s waste and pollution.


“We should create a new type of city – the city of the 21st century – a smart, people-centred city, one that is capable of integrating the tangible and more intangible aspects of prosperity; a city able to rid itself of the inefficient, unsustainable urban habits of the previous century,” said Joan Clos, UN-Habitat’s Executive Director.

“It is time for changing our cities and for building new opportunities,” he stated...

China Looks to Future with Tianjin Eco-city...

China Looks to Future with Tianjin Eco-city... | Développement durable et efficacité énergétique | Scoop.it

With a cityscape that is all cranes and thrusting new towerblocks, Tianjin Eco-city could at first glance be any of the hundreds of urban areas in China expanding at a breathless pace.

But this joint Chinese-Singaporean project, which was started in 2008 and will be finished in 2020, aims to be something very different from the norm: a model for more sustainable development in a country urbanising at a pace unprecedented in history.

"With rapid urbanization, there will be new cities being built. When you're building new cities you start by going for principles of sustainability," says the project's chief executive, Ho Tong Yen, a Singaporean diplomat and government official...
