What is LEED?
LEED Stands for Leadership in Energy and Environmental Design
Who is behind LEED?
The U.S. Green Building Council, or USGBC, is an organization of stakeholders, including 13,000 member organizations, 77 chapters and 181,000 LEED professionals. USGBC created the LEED Rating System in 1999, which has since grown to become the most widely recognized and used green building program in the world.
USGBC continues focuses to develop the LEED standards and growing the LEED brand, while its subsidiary organization, the Green Building Certification Institute, or GBCI, is in charge of LEED Building Certification and LEED Professional Accreditation programs. Though separate, the two organizations are connected through the LEED Online system.

What is LEED Certification?
LEED is a green building certification developed by the United States Green Building Council in 1999. LEED certified buildings, on average, are more energy efficient than non-certified buildings and have a reduced carbon footprint and operating costs.
The LEED rating system is based on awarding points in six different credit categories: Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality and Innovation in Design. The specific LEED certification depends on how many point are achieved. A building can be LEED Platinum, LEED Gold, LEED Silver or simply LEED Certified. Studies have found that buildings, which achieve Platinum and Gold ratings, have delivered close to 50% in energy savings.

to be LEED certified, a building must accumulate a minimum of 40 points on a 110-point LEED rating system scale. The only exception is the LEED For Homes Rating System, which must earn 45 points on a136-point scale.

Why Get A LEED Certification?
LEED certified buildings have lower operating costs and higher asset value. LEED Buildings are qualified for tax rebates, zoning allowances and other incentives depending on local regulations. Studies have shown that they conserve energy and water, reduce greenhouse gas emissions, and provide a healthier and safer environment for occupants. Also, the waste sent to landfills is reduced compared to tradtional construction projects, contributing significantly in healthier environment.
So, LEED Certification is for Buildings. What is LEED Accreditation?
LEED accreditation is the proof that individual professionals have demonstrated their knowledge of green buildings and the LEED rating systems. Today there are over 180,000 LEED Professionals worldwide. There are various types of LEED accreditation, just like there are different rating systems for LEED certification of buildings.
The LEED Green Associate and LEED Accredited Professional are internationally recognized designations granted by the Green Building Certification Institute (GBCI). The GBCI was established in 2008 as a subsidiary of the USGBC and is tasked with governing LEED building certifications and professional designations. The LEED Green Associate Exam serves as the first step for becoming certified in any of the 5 different specialties under the LEED Accredited Professional umbrella: Building Design & Construction, Operations & Maintenance, Interior Design & Construction, Homes, and Neighborhood Development.
LEED credentialed professionals are a highly valuable asset to any business that is involved in the green building industry as they provide expert knowledge of the LEED certification process and best practices in sustainable building design.
LEED Accreditation
What Are the Different Levels of LEED Accreditation?
LEED Credentialing process has three levels for individual accreditation. The first level is the LEED Green Associate that covers the basics for the LEED project process, LEED rating systems, core sustainability concepts and terminology.
The second level is the LEED AP with a specialty. Candidates must have work experience in a LEED Project (See CleanEdison's Project Experience course). Individuals are tested on the Fundamentals of Building Green and on their chosen LEED specialty. LEED AP specialties consist of five different exams from LEED Homes and Green Building Operations and Maintenance to LEED for Neighborhood Development as shown at the graphic below.

The third level is the LEED Fellow. This is a non-exam accreditation since candidates can only be nominated from a LEED AP accredited individual after ten or more years of experience in the field. After the nomination candidates are evaluated on certain criteria including: Technical Proficiency, Education and Mentoring, Leadership, Advocacy, Commitment and Service, before they become a LEED Fellow.
Benefits of Becoming Accredited
Obtaining a LEED Professional Credential shows that you are an expert in the field, with technical knowledge, experience and credibility. Employers and building owners rely on the LEED Accreditation process for finding professionals in sustainable design, construction, operations and maintenance of buildings and neighborhoods, saving energy and resources, reducing pollution and creating a better environment for the whole community.

LEED V4 - What’s New
LEED V4, expected to be released in June 1st 2013, is the newest upgrade to the rating systems. The upgrade comes with changes in three main forms: new impact categories, new market sectors for each rating system, increased technical rigor and streamlined services.
USGBC attempt to create new impact categories to better emphasize the potential of projects to contribute positively to their community and to the environment. The hope is that LEED projects will have a greater incentive to achieve higher credits and better environmental, economic and social outcomes.
The final public comment period is now over, in which every stakeholder was able to voice their opinions on the changes. LEED V4 is introducing several programs that might be unfamiliar even to the most LEED-savvy professionals: BUG ratings, LID infrastructure, BECx, and spatial daylight autonomy are just few examples.
