What is LEED?
LEED is a third party certification program and the nationally accepted benchmark for the design, construction and operation of high performance green buildings. Developed by the U.S. Green Building Council in 2000 through a consensus based process, LEED serves as a tool for buildings of all types and sizes. LEED certification offers third party validation of a project’s green features and verifies that the building is operating exactly the way it was designed to.

What types of buildings can use LEED?
LEED certification is available for all building types including new construction and major renovation; existing buildings; commercial interiors; core and shell; schools and homes. LEED systems for neighborhood development, retail and healthcare are currently pilot testing. To date, there is over 4.5 billion square feet of construction space involved with the LEED system.

How does LEED work?
LEED is a point based system where building projects earn LEED points for satisfying specific green building criteria. Within each of the seven LEED credit categories, projects must satisfy particular prerequisites and earn points.

The five categories include Sustainable Sites (SS), Water Efficiency (WE), Energy and Atmosphere (EA), Materials and Resources (MR) and Indoor Environmental Quality (IEQ). An additional category, Innovation in Design (ID), addresses sustainable building expertise as well as design measures not covered under the five environmental categories. The number of points the project earns determines the level of LEED Certification the project receives. LEED certification is available in four progressive levels according to the following scale:

There are 100 base points; 6 possible Innovation in Design and 4 Regional Priority points

  • Certified 40–49 points
  • Silver 50–59 points
  • Gold 60–79 points
  • Platinum 80 points and above

Does green building cost more?
No, green buildings do not have to cost a penny more. LEED certified projects to date demonstrate that
you can achieve LEED certification and reap its many benefits with a common-sense approach to design
with no additional dollars. Depending on your green building strategy and the level of certification your
project is targeting, there may be mid- and long-term ROI associated with additional green features that
merits an investment in first costs.
