Sustainability Journey Launched in 2006
• Sustainability is a holistic effort• Buildings
• Building envelope, roofs• Energy performance contracting
• Grounds• Walking and bike trails• Detention ponds• Selective decrease of mowed and maintained areas• Native plants
• Attitudes• Attitudes• Recycling program• Monitoring and reporting (STARS, Greenhouse Gas survey, leadership reports)• Curriculum development and student/faculty involvement• Be a role model for students, the county, state and nation
• LEED (Leadership in Energy & Environmental Design)• A program that provides third-party verification of green buildings. • Projects satisfy prerequisites and earn points to achieve certification.• Requirements differ for each rating system.• Implemented by U.S. Green Building Council (USGBC), a non-profit
dedicated to “changing the way buildings and communities are designed, built and operated.”

LEED Options for Higher Ed
Rating System LEED for Schools New Construction Existing Buildings
2009 Version of Schools Focused on K-12
Description Originally developed to address the design and construction of K-12 schools.
Based on LEED for New Construction, with key additions:
LEED for New Construction & Major Renovations takes an integrative approach to producing buildings that are designed to be efficient and have a lower impact on their environment.
Design and construction decisions lay foundation for sustainable operations and maintenance.
Encourages owners of existing buildings to implement sustainable practices and reduce the environmental impacts. Key areas:
• exterior site maintenance• water and energy use• environmentally preferred
% of building square footage dedicated to learning space
More than 60% core and ancillaryincluding 25%+ core
40-60% core and ancillary, including 10%+ core
Less than 40% core and ancillary OR less than 10% core
K-12 Must use LEED for Schools Should use LEED for Schools Should use LEED for Schools
Other than K-12 Should use LEED for Schools May use LEED for Schools Should not use LEED for Schools

#3. Focus on Lighting Quality
One Point Available for Lighting Quality• Choose four of the following strategies (summarized).
1. Avoid high angle glare2. Use light sources with a CRI of 80 or higher. 3. Use long-life sources (> 24,000 hour for fluorescent; > 70,000 for LED)4. Minimize direct-only overhead lighting5. High reflectance ceilings; mid reflectance for walls; low reflectance floors6. Consider reflectance of furniture and work surfaces7. Manage contrast ratios between walls and work plane8. Manage contrast ratios between ceilings and work planeg g p
• Refer to IESNA (www.iesna.org) for details• Require designer/engineer to document compliance to standards
#3. Focus on Lighting Quality
One Point Available for Lighting Quality• Visual impacts of quality lighting:
• Reduced glare• Reduced shadows

#4. Reduce Light Pollution
• Reduce light trespass onto neighboring properties,• Improve nighttime visibility through glare reduction, p g y g g ,• Reduce sky-glow
#4. Reduce Light Pollution
Insist on Precise Optical Control• Light only those areas that need to be lighted.• Minimize site lighting with a purposeful approachg g p p pp• Consider full cutoff fixtures, low-reflectance surfaces and low-angle
directional outdoor lighting
