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... Via Lauren Moss

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.

The amount of renewable energy produced in the U.S. last year was slightly less than the global average of 15%, meaning that America is not too far off the mark compared to the rest of the world. The UN Framework Convention on Climate Change has set a worldwide goal of 30% renewable energyby the year 2030, but they currently remain pessimistic about the ability of countries to achieve that goal, and believe that there could be at least a nine-percentage point deficit between reality and their goal.
