The APS Solar Pavilion, which covers 17,280 square feet above the Chase Field plaza near the ballpark's western entrances and ticket office, provides extra shade over the ballpark's heaviest used entrances and generates 100,000 kWh of solar energy; enough electricity to power the lights at Chase Field for 11 home games
Removed over 1,000 miles of paper towels from the annual waste stream by replacing paper towel dispensers with 50 Xlerator hand dryers in concourse restrooms
All concourse lighting has been converted to energy-efficient LED resulting in 60% savings in power consumption annually
Upgraded lighting in the Chase Field parking garage has resulted in a 40% savings in annual power consumption
The Arizona Diamondbacks are proud members of the Green Sports Alliance, a groundbreaking coalition of professional sports teams and sporting venues committed to promoting "greening initiatives" in sports.
The nonprofit organization was launched in 2011 with founding members from six major leagues (MLB, NFL, MLS, WNBA, NHL, NBA), their home arenas, the Environmental Protection Agency and Natural Resources Defense Council. It is the first time teams from the six major professional sports had collaborated on a common environmental agenda. Since the launch, over 400 sports teams and venues have joined the Alliance.
Salt River Fields at Talking Stick is the Spring Training home of the D-backs and Colorado Rockies. The facility, which opened in February 2011, received LEED Gold Certification for New Construction, and is the first LEED Gold-certified sports venue of its kind in the United States.
Sustainable project elements include siting the stadium to provide maximum shade, using native vegetation, minimizing storm water runoff, maximizing the amount of fresh air brought in through its HVAC systems and using grass-covered parking lots.
Only 1/3 of the venue's parking lots are constructed using asphalt. The remaining 2/3 overflow parking lots are grass-covered, allowing them to double as playing fields for the community when not in use. The lots are used for overflow parking only 15 percent of the time throughout the year.
By incorporating as much native planting as possible into the overall site design, water is absorbed back into the ground instead of contributing to storm water runoff. Passive water harvesting is accomplished via desert arroyos (washes) which flow throughout the site. More than 85 mature trees and cacti - located throughout the site - were uprooted and replanted at the new site to provide shade for venue patrons including 35 trees, 45 creosote and nine cacti. In addition to the salvaged vegetation, 2,400 native trees were planted to provide shade and habitat. The onsite retention pond further reduces storm water runoff as well as provides a habitat for native species. The project has calculated a 45.5 percent savings in the use of potable water through low-flow and water-efficient fixtures.
Instead of ventilating the locker rooms from the top down, displacement ventilation - located at the base of the lockers - saves energy by supplying conditioned air in the occupied space range. In addition, strategies such as installing operable windows and maximizing occupant lighting and thermal control have contributed to the project achieving a 23.5 percent energy savings.
The stadium was designed with the angles of the sun in mind to provide maximum shade. The venue's location on the site and monumental roof provide relief from the southwestern sun for all patrons without compromising views and vistas to the surrounding natural landscape. Terracotta shade screens are attached to the exterior clubhouse faÃ§ades to provide further shade from the sun.
The majority of the venue's exterior skin is constructed of masonry materials, harvested from the Salt River Pima-Maricopa Indian Community soil. Salt River Materials Group, a local enterprise owned by the SRPMIC, provided these materials. In total, 40 percent of the building materials are derived from local suppliers and vendors.
