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.

Green and Healthy Buildings: monitoring consumption & ecology in the built environment

Green and Healthy Buildings: monitoring consumption & ecology in the built environment | Développement durable et efficacité énergétique | Scoop.it

According to the United Nations Environment Programme, buildings account for approximately 40 percent of worldwide energy use and are responsible for 30 percent of greenhouse gas emissions. They also play an important role in the health and wellbeing of those who inhabit them each day.

The mass of information about what makes a building green tends to concentrate on new and innovative designs that create beautiful photo spreads. While such examples are inspiring, they make up a very small percentage of all buildings in operation.

Green Buildings Alive is an environmental initiative aimed at collecting and sharing data on existing buildings between 10 and 60 years old. The data is collected from office towers in Australian Central Business Districts (CBDs) and shared on a public website.


For more on this innovative, environmental initiative that provides interactive visualizations of building-performance data to help understand the complexities and relationships among sustainability, health, and energy, read the complete article

Global Warming: a new report on loss of life and global economic damage

Global Warming: a new report on loss of life and global economic damage | Développement durable et efficacité énergétique | Scoop.it

From devastating floods in China and the Philippines to droughts in Africa, the extreme weather patterns that hit the United States have impacted sites around the world as the face of global warming.

According to a new report, climate change has already contributed to 400,000 deaths per year and over $699 billion, 0.9 percent annually, in loss to gross domestic product (GDP). The report estimates even greater damage from air pollution caused by the burning of fossil fuels. also driving global warming.

'Climate Vulnerability Monitor: A Guide to the Cold Calculus of a Hot Planet (2nd Edition)' was written by over 50 scientists, economists and policy experts, and commissioned by 20 governments. The study calculates and compares the vulnerability of 184 countries in terms of environmental disasters, habitat change, health impact and industry stress.

Read on for statistics, implications and global health issues related to these new findings, proving that 'failing to deal with global warming will have real and lasting impacts on local communities, economies, health and safety, and people around the world.'

Infographic: The Impact Of EV Solar Charging Stations

Infographic:   The Impact Of EV Solar Charging Stations | Développement durable et efficacité énergétique | Scoop.it

There are more benefits to driving a solar charged vehicle than meets the eye.


As technology for these vehicles improve, so will their travel distance and accessibility, as charging stations are becoming more common, with locations at airports, malls, and even college campuses.

Electric vehicles are good for the environment, and recent studies have shown they also play a role in our health. 


This infographic outlines their benefits, compares emissions from the different types of charging stations, maps locations across the US, and summarizes the positive impact electric vehincles have on the economy, environment and our health.

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...

Neoliberalism, Degrowth and the Fate of Health Systems

"Degrowth recognizes that humanity’s access to the earth’s resources and services of the biosphere are constraints upon socioeconomic activity. It also holds that politics and economics cannot trump thermodynamic and ecological realities. It places the limits to growth and ecological overshoot at the center of the predicaments Homo sapiens confront. It connects to culture and political/economy through this root public policy question: How to equitably distribute a shrinking economic pie?"

 



"We developed our world economy with oil as our security against future debt, always able to borrow more with the ‘certainty’ that cheap oil would provide future income to pay it off.

… This is the fundamental truth that eludes our cornucopian economists: our economy functions on energy input, not money output. Without endless cheap energy you can’t have endless employment. Our infinite demand has hit the wall of finite resources…[xxix]

Timothy Garrett, a contemporary physicist, has developed a model of economic activity as a heat engine -complete with a coefficient of output- which, expressed in lay terms means the economy is dependent for its output on the amount of energy –not capital or money or labor- flowing into it."

Must-read analysis by Dan Bednarz and Allana Beavis on what "the end of cheap energy and growth" means for Western health systems.
