New Levels of LEED

A new top-level LEED classification called Unobtanium is being proposed to replace the currently proposed Protactinium level, leading to a possible schism in the growing green building rating system. Whether Protactinium or Unobtanium becomes the new top-level of the LEED rating system…?
Earlier this year, officials proposed a new level of LEED (Leadership in Energy and Environmental Design) that is higher than the current top-end Platinum rating. The new Protactinium level introduces more stringent requirements to ensure the purity of the design team and to verify their worthiness to obtain such a noble rating for their building.
