LEED Accreditation

Want to improve your facility’s operating efficiency, reduce energy consumption and costs, and increase and protect value?

Excel’s LEED-accredited experts can help.

“LEED” stands for “Leadership in Energy and Environmental Design.” It’s the U.S. Green Building Council’s nationally accepted standard for designing, building, and operating high-performance “green” buildings. Through LEED’s rigorous accreditation program, professionals not only demonstrate their mastery of green building principles and practices, but also the criteria a facility must satisfy for LEED certification as well.

Our LEED-accredited experts can help you achieve your most demanding green building objectives. This includes:

Guiding and supporting green design
Integrating systems and sub-systems to LEED standards
Expediting the LEED application and certification process
