Tidbit Tuesday | Green Buildings in Philadelphia

On Tuesdays, the Mayor’s Office of Transportation & Utilities (MOTU) posts a map or graphic that tells a story about transportation or utilities in the City of Brotherly Love.

How can we produce less waste, conserve energy, and minimize our carbon footprint? One way to do this is by constructing “green” buildings, such as those that meet LEED standards. LEED, which stands for Leadership in Energy and Environmental Design, was established by the US Green Building Council in 1998. Buildings earn LEED certification by demonstrating that they are constructed using responsibly-sourced materials and practices and that they are maintained and operated in a resource-conscious way.  Some strategies for achieving LEED certification, available in grades from certified to, silver, bronze, gold, and platinum, include using recycled building materials, installing green roofs, using efficient shading devices on windows, and incorporating efficient plumbing fixtures which use less water.

Today, we are taking a look at the number of LEED Certified buildings in Philadelphia, using data from the Pew Charitable Trusts. The graph below shows that the number of green buildings has been steadily increasing in Philadelphia since 2005. A zoning code adopted in August 2012 further encourages the construction of green buildings by offering density bonuses for projects that meet LEED Gold or Platinum standards.
