DESCRIPTION
LEED is an internationally recognized green building certification, providing third-party verification that a building was designed and built using strategies and techniques aimed at improving energy savings and water efficiency, reducing CO2 emissions, indoor environmental quality, and improving stewardship of resources and sensitivity to their impacts. The District’s Green Building Policy requires that all new buildings and major renovations obtain the highest possible Leadership in Energy and Environmental Design (LEED) Silver certification from the U.S. Green Building Council. Currently, the SDCCD is on track to obtain 41 LEED certifications, more than any single organization in San Diego County.

Green Building Policy
The Board of Trustees is committed to environmental stewardship as a fundamental operational objective and integral to fulfilling our educational mission.
The Board recognizes its fiscal responsibility to use taxpayers' dollars wisely for the best long-term, long-range investment.
The goal of this policy is to provide working and learning environments that are: Efficient in use of energy, material and water Easy to maintain and operate Thermally, visually and acoustically comfortable and healthy Safe and secure Sited in an environmentally responsible manner.

Green Building Policy ImplementationPerformance Goals
Exceed Title 24 of California Code of Regulations energy efficiency standards by at least 10%.
Ten percent of the energy utilized by the project must be renewable with at least 5 percent generated on site.
Divert at least 75% of construction and demolition debris from landfills.
Pursue formal LEEDTM certification witha minimum of 33 pointsresulting in a LEEDTM Silver rating, with a goal of LEEDTM
Gold on applicable projects.
