Big Picture Sustainability People Planet Staff Profit 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. Green Buildings Buildings – Complete Arnett Hall Andrews Hall ATLAS Leeds Business School Addition University Memorial Center Visual Arts Complex Wolf Law Buckingham Hall 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.

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. Campus Renewable Energy Mountain Research Station Housing Maintenance Facility Coors Event Center Wolf Law School – live monitoring 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.
