  • Operable windows have been placed to optimize views and daylighting with sunshades, high performance glass, and perimeter-zoned photocell direct/indirect light fixtures.
  • Exterior envelope and building systems are designed for energy efficiency with a concerted effort to use sustainable materials and finishes where appropriate.
(7) Solar Panels on Engineering Building
  • Installed in June 2009 in partnership with the Governor’s Energy Office.
  • 18.9-kW solar array produces more than 25,000 kWh per year and reduces the greenhouse gas emissions of the building by 18.3 metric tons per year.
  • The 108 panels tie directly into the building’s electrical system.
View the following sites (8a -8d) from the Lory Student Center Deck (West of Main Ballroom).
(8a) Indoor Practice Facility
  • Designed for use by multiple sports programs with a 70-yard synthetic turf field, 4-lane synthetic sprint track, batting and golf cages, and basketball/volleyball court.
  • Uses natural daylighting, creatively cleans stormwater with vegetation before leaving site, and features water-conserving landscaping.
  • Achieved LEED Gold certification in 2010.
(8b) Recreation Center
  • Re-use of more than 75 percent of existing structural walls, floors, and roofs.
  • Water-efficient landscaping and 100 percent use of non-potable water.
  • Achieved LEED Gold certification in 2011.
(8c) Lagoon revitalization
  • Project improves flood prevention by increasing detaining capacity on campus.
  • Irrigation system uses untreated College Lake water instead of treated water.
  • Wetland bioremediation of playing field runoff.
  • Waterfall bioremediation and oxygenation of Lagoon water.
(8d) Academic Village
  • Aspen Hall opened in fall 2009 and is CSU’s first LEED Gold certified residence hall.
  • On-site thermal plant features solar panels, 95 percent energy-efficient boilers for heating water, and an innovative system that makes ice at night when electric rates are lowest and then reverses the process during the day to cool the building.
  • Ram’s Horn Dining Center features a pulper that reduces water use and creates a compostable by-product from all food and paper waste.
(9a) Transit Center
  • The first LEED Gold building on campus.
  • Recycled granite, concrete, and drywall were used in the construction of the facility.
  • Recycled and/or salvaged 75 percent of construction, demolition, and land-clearing waste created in the construction process.
(9b) Aspen Grille
  • Student-run restaurant that uses local food products, energy-efficient grills, low-flow faucet aerators, and biodegradable cleaning products.
  • Twenty varieties of “low-carbon lettuce” are biked over from the campus Greenhouse.
(10) Lake Street Parking Garage
  • Opened in March 2010 on the site of an existing parking lot.
  • Features four tiers with 900 parking stalls as well as street-level retail and office space. Covered bicycle parking is also available as well as spots reserved for low-emitting vehicles.
  • Features a 133 kW, 9,000 square-foot solar panel array above the fourth tier.
  • Achieved LEED Gold certification in 2012.
(11) Microbiology Study Lounge
  • Green roof demonstration in partnership with the Department of Horticulture and Landscape Architecture to determine best practices.
(12) Academic and Training Center
  • Contains a state-of-the-art weight room, four private tutoring rooms, a general study hall with 30 computer workstations, and a multipurpose room for meetings.
  • Trees provide building shade, glass is shielded from direct sun exposure, and efficient heating and cooling systems were installed to minimize operational costs.
  • Achieved LEED Gold certification in 2010.

Foothills Campus (The following sites are not part of the walking tour. They are located on CSU’s Foothills Campus.)
Solar Plant
  • A public-private partnership among CSU, Xcel Energy, and Fotowatio Renewable Ventures.
  • 5.3 MW array with an annual expected output of 8,500,000 kWh, enough to cover 33 percent of the electricity consumed on the Foothills Campus.
  • 30-acre plant with more than 23,000 solar panels.
Research Innovation Center (RIC)
  • Hot-water preheating system at the boiler that allows the use of boiler exhaust to heat water for the building systems.
  • Efficient design will help reduce natural gas use for the building.
  • 57-kW photo voltaic array will be installed.

Biomass Plant
  • Burns approximately 600 tons of wood chips from fire mitigation projects each year to heat water and displace natural gas use.
  • The plant has a rating of 46 bhp.
  • Biomass energy produces 96 percent fewer overall emissions than natural forest fires and 97 percent fewer than prescribed burning.
Earth Flow Composting Project
  • Large-scale in-vessel composter on Foothills Campus.
  • The Earth Flow bin will turn the 300,000 pounds of compostable material from the dining center pulpers
    as well as some organic material from campus into soil amendments.
  • Soil is targeted for use in campus landscaping projects.
