Campus Goals
• Governor’s Executive Orders for “Greening of State
Government” by 2012
– Reductions in energy, water, Zero waste goals, paper and
waste from construction and demolition, and fleet
petroleum
• Long-term campus commitment to reach carbon neutrality
– Energy conservation
– Large scale renewable energy
– New technologies
• Challenges: Tangible steps towards our goal but unable to
show date certain CO2 neutrality

Why LEED?
• Leadership in Energy and Environmental Design
(LEED) is a set of progressive and best practice
recommendations/standards set forth by U.S. Green
Building Council (USGBC) to promote sustainable
building design and construction.
• Shifts discussion from initial costs to long-term
operating costs
LEED Gold “Plus” Strategy
• To support our near term goal of energy
conservation and long-term goal of carbon
neutrality, it makes sense to continue with
our goal of LEED Gold and go deeper into
the category of Energy and Atmosphere
(>45% better than ASHRAE 90.1) during
current period of campus expansion.

Projects under
construction/renovation
and on track to receive
at least LEED gold –
Campus benefits from LEED standards
– minimal design and construction costs
result in energy savings of 25% - 35%;
investment payback to achieve Gold
standard takes roughly 1-2 years.

Campus Renewable Energy
100% financing of Solar PV by
campus and 3rd party venture
capitalists using:
• Amendment 37 incentives,
• Xcel rebates,
• Tax credits, and
• Accelerated depreciation
charges.
Williams Village North – This summer the
Solar PV panels on the parking car ports begin
adding 140,000 kWh of energy per year.
Center for Innovation
and Creativity – 370 newly
installed Solar PV Panels at the
CINC building will produce
approximately 10% of the
building’s annual energy needs –
enough energy for 20 regular
sized homes.

Challenges: Expanding on-site renewable energy; space (land/roof);
declining rebates and incentives and price point.
Energy/Water Conservation in
Research Labs
Why do you
focus on
Research labs?
Labs are 5-7 times more
energy and water
intense than campus
classrooms or general
offices.
CU Green Labs Program
Focusing on:
• Major plug loads and large equipment
• Incentive programs to retire or upgrade old energy and
water inefficient lab equipment and appliances (Fume
hoods, refrigerators, ultra cool freezers, etc.)
• Offer free timers, freezer/refrigerator maintenance
program
• Identifying EcoLeaders
• Behavioral Change: Education, Communication program,
posters, etc.
Challenge: Getting the information to the researcher, speaking their
language, accomplish without incentives.
Faculty Engagement – Peak to Peak
Project
• 50 faculty members signed up for a two day sustainability work
shop.
• Attendees will each receive a $500 stipend after showing they’ve
incorporated sustainability into at least one of their upcoming
courses.
• CU-Boulder faculty and staff were the speakers at the workshop.
Integrated Pest Management
Task Force
Goal: Turf and landscape areas synthetic pesticide free
by 2016
• Collaboration between students, the Environmental
Center, Facilities Management and Housing and
Dining Services
 Reductions in the highest student use areas first,
 Significant reduction in chemical exposure to
students, faculty and staff in its first year of
implementation,
 Substantial environmental and ecosystem benefits
realized within the first five years of the program.
Challenges: Perceptions, logistics, implementing a project
with no direct cost benefit.
Conservation Opportunities and
Deferred Maintenance (DM)
• Deferred Maintenance refers to opportunities to repair of replace building systems in
need of attention.
• Significant investment to stay current. Most campuses unable to maintain the
needed investment.
• There are strong correlations between attending to deferred maintenance backlog
and achieving resource conservation goals.
• Combine DM Funds and Conservation funds in favor of reducing DM level where
possible.
• Examples of DM opportunities in an old building
• Lighting control improvement
• Motors
• HVAC controls
• Building Envelope
Challenges: Problem scale; ongoing collaboration between operations and
conservation groups; age of buildings.
