Green Building Policy ď Ž The
Board of Trustees is committed to environmental stewardship as a fundamental operational objective and integral to the strategy of fulfilling our educational mission.
ď Ž The Th
Board B d off Trustees T t further f th recognizes i its it fiscal fi l responsibility to use taxpayers' dollars wisely for the long-term, eschewing the short-term economy where there is a better long-range long range investment investment.
ď Ž The
goal of this policy is to provide District students, faculty and staff with working and learning environments i t that th t are healthy, h lth thermally, th ll visually i ll and d acoustically comfortable; energy efficient; material efficient; water efficient; easy to maintain and operate; safe and secure and sited in an environmentally responsible manner. 3

Green Building Policy Implementation Methodology ď ŽIncorporate
life-cycle costing that includes initial construction costs, costs operating costs, costs maintenance repair and replacement costs to evaluate the longterm investment value of design alternatives
design so that buildings systems are designed to perform as a whole rather than as component parts with an emphasis on efficiency and performance
commissioning g and facility y performance p evaluations to assure that the building systems meet the occupant requirements and design intent
Total Cost of Ownership Example
50 year design life
100,000 square foot classroom building
Design and construction cost - $30 million
Capital Renewal: 2 percent of current replacement value (APPA benchmark)
O&M Budget $5.69/square foot
Inflation: 3 percent
Savings in O&M and Capital Renewal Total Cost of Ow nership
Save 5% in Cap. Renewal

Save 10% in O&M
Environmental Sustainability Policy ď ŽEnvironmental
sustainability is an essential goal of the Di t i t Global District. Gl b l warming, i di diminishing i i hi resources and d escalating costs of energy and rubbish disposal require that management g at all levels focus on the efficient and effective use of energy and resources. This policy expresses the Boardâ€™s intent to implement a Districtwide Environmental Sustainability program within the constraints of current staff authorization.
WHEREAS, the San Diego Community College District is a regional leader of sustainability and green applications; WHEREAS greenhouse WHEREAS, h gas emissions i i endanger d th the S San Di Diego environment, health, and economy; WHEREAS, clean air and water are critical issues for all San Diegans, and transportation-related (e.g., automobile, truck, train, and ship) air pollution has a negative impact on public health and the environment; WHEREAS, sustainability, by definition, is a fundamental issue of importance in the 21st century; and WHEREAS there is tremendous mutual benefit for the institutions of the WHEREAS, San Diego Community College District and the region to develop and implement policies supporting environmental sustainability outreach ad integration; NOW THEREFORE NOW, THEREFORE, BE IT RESOLVED, RESOLVED th thatt the th San S Diego Di C Community it College District proclaims that as an institution of higher education, it will exercise leadership, both on campus and throughout the community ; by modeling sustainability practices in daily activities,; by influencing future campus plans l th thatt promote t sustainable t i bl applications; li ti and db by sharing h i knowledge of and expertise in environmental sustainability issues. 10
Leadership in Energy and Environmental Design (LEEDTM) provides standards for environmentally sustainable construction.
New Construction: LEED-NC is designed to guide and distinguish hi h high-performance f commercial i l and d iinstitutional tit ti l projects, j t iincluding l di office buildings, high-rise residential buildings, government buildings, recreational facilities, manufacturing plants and laboratories. Existing Buildings: LEED-EB LEED EB addresses whole-building whole building cleaning and maintenance issues (including chemical use), recycling programs, exterior maintenance programs, and systems upgrades. Commercial Interiors: LEED-CI applies to commercial interiors for the tenant improvement market. Core and Shell: LEED-CS applies to base building elements such as structure, envelope and the HVAC system and is meant to be compatible with CI. CI 11

Green Furniture Policy The
San Diego Community College District works with furniture vendors who are: Practicing
responsible manufacturing Demonstrating a corporate-wide commitment to reduce waste, air emissions and effluent discharges Developing strategies to reduce water and energy use and minimize the impact of manufacturing on the environment Designing and producing products and materials with a high percentage of recycled content Using g cradle-to-cradle design g concepts p
District’s Green Building Policy calls for us to support and work with firms and professionals that are LEED credentialed or follow LEED principles.
GREENGUARD C Certification tifi ti provides id a standard t d d ffor furniture and interior products and can earn points toward LEED certification.
To receive certification, the GREENGUARD Environmental Institute (GEI) tests products for low chemical emission levels.
