The Leadership in Energy and Environmental Design program provides a system to evaluate green building design and offers recognition for particularly environmental friendly buildings.
The program awards points for rainwater collection, reuse systems, energy-efficient lighting, low-flow plumbing fixtures, and more.
LEED's newest incarnation incorporates regional credits — extra points identified as priorities in a project's environmental zone. It also has undergone a re-weighting of credits to reflect energy efficiency and climate change as priorities.
And LEED-accredited buildings get more than just green bragging rights. According to a recent study, LEED-certified buildings outperform their peers in areas such as occupancy, sale price, and rental rates.
