30 seconds with Tim Cahill …
Q. How does having a sense of place change the design process?
A. “It can have a dramatic effect. As architects, we want our clients’ facilities to incorporate their communities’ unique character as well as enhance it. For example, when designing Levi’s Stadium in Santa Clara, California, for the San Francisco 49ers, we not only wanted the stadium to express the 49ers’ tradition and branding but also to reflect California and its culture. It’s in Silicon Valley, so it needed to suggest the region’s food and wine culture and have the highest level of technology and sustainability available.”
Q. So environmental sustainability can play a major role as well?
A. “Absolutely. As technology and awareness of environmental concerns have evolved over the past few decades, we’ve seen sustainability become an important way to improve the bottom line for clients as well as achieve a positive societal impact. Levi’s Stadium incorporates a green roof, the latest LED lighting and water conservation technology, as well as solar panels. While the LED lighting is approximately 40 percent more efficient than standard stadium lighting, the stadium’s solar panels also generate enough electricity to power the stadium during 49ers home games.”
Q. What else has changed about stadium design?
A. “We’ve seen expectations grow regarding amenities as well as access to wireless, mobile technology. People often think of suites and premium seating when we talk about such improvements, but it extends to each and every fan. In Santa Clara, for example, the lower bowl is larger than any other in the NFL, making every seat feel closer to the action. Plus, the concourses are wider than traditional designs, giving fans more room to move around and interact with the space as well as each other.”
