Sustainable Strategies for Expansive Facilities
Fentress’s portfolio is valued at over $43 billion and serves more than 650 million people annually.
Strategies of waste reduction, recycled content maximization and conservation are consistent regardless of the scale of the project. However, there are a few consistent strategies to consider when designing expansive facilities:
- Harnessing daylight to minimize energy use and control heat gain.
- Integrating with the community and multimodal transportation networks.
- Creating spaces and systems that will welcome future adaptations.
The following projects illustrate these strategies:
Fentress’ entree into expansive facilities came with the commission to design the 2,250,000-square-foot Passenger Terminal Complex at Denver International Airport. Fentress took over a project suffering from uninspired design, exorbitant cost and schedule overruns. The solution to reverse these incontestabilities was the creation of a light-filled volume to echo Colorado’s dramatic mountain scenery. Despite skepticism on the ability of a tensile structure—then a nascent building technology—to achieve the necessary spans and withstand area snow volume, Fentress countered precedent and flipped the airport’s massive infrastructure from the roof to underground. The shift allowed up to 150-foot light-filled roof peaks to come to life while conserving resources. Hundreds of tons of structural steel and building materials were eliminated. The design also powerfully harnessed natural light. The Denver airport dramatically changed contemporary ideas on airport design, introducing expressive form to welcome travelers to a place and its culture.
In 2010, the Colorado Convention Center (CCC) announced its certification through LEED–EB, making it—at 2,300,980 gross square feet—the largest convention center certified under LEED-EB to date and among the largest LEED-certified convention facilities in the US. As Denver residents, Fentress Architects recognized the Center’s potential to reshape the city. So, the focus was on establishing and reinforcing its connections with the urban surroundings. The integration of a light rail station within the building has advanced economic growth and revitalization initiatives for the once-barren 14th Street. Fentress’ work catalyzed a surge of infill development that continues to bring new life, investment and activity to Denver.
At 1.4-million square feet, Tom Bradley International Terminal at LAX became the world’s largest LEED Gold certified airport when it opened in 2013. Adding to the complexity of this immense facility is the fact that renovation and construction occurred while the terminal remained fully operational. Fentress’ state-of-the-art, people-centered design allows abundant natural light from clerestories and broad windows. Environmentally-friendly concepts were integrated at every stage and every level of the project.
Operational and performance goals of improved energy performance, reduced water consumption, waste, and emissions were met, in part, through integrated strategies that aligned with the larger aesthetic and experiential objectives. For example, Fentress conducted extensive sun-shading studies during the design of the roof structure to minimize heat gain and maximize daylighting.
Additional strategies include a high-performance thermal envelope, drought-tolerant landscaping, the provision of a purple pipe infrastructure in anticipation of future availability of municipal-supplied non-potable water, programmed space for recycling, an early procurement program for materials that contain recycled content, specification of non- or low-emitting materials, and the incorporation of free shuttle bus service to provide better connectivity to and from the airport, the city and the region.
LEED Gold-certified Ralph L. Carr Colorado Judicial Center in Denver remains one of the most sustainable courthouse complexes in the United States. It hosts the Colorado Supreme Court Law Library, a visitor’s Learning Center, and a 4,000-square-foot green roof. The granite-clad Neoclassical building respects the archetypal presence of its neighbors. It steps back to acknowledge a center of learning: the Denver Central Library. The design also focused on completing the flow of a pedestrian walkway between the Library and State Capitol. The result is in a direct, physical link to the Center’s functions for users and visitors as they move across the campus. The Carr Judicial Center makes substantial use of durable and recycled materials. It remains 30-percent more energy efficient than standards demanded. In addition to its green roof, sustainable features include a photosensitive daylight harvesting illumination system, a state-of-the-art and highly efficient mechanical system, and locally sourced materials such as marble from Marble, Colorado.
