Thomas Knittel

Thomas Knittel, AIA, LEED AP BD+C, is a senior principal – design in HOK’s Los Angeles studio. He is the firm’s leading expert in biomimicry – drawing inspiration from natural systems to solve human problems – and holds a Biomimicry Specialty Certificate from Biomimicry 3.8. The organization also honored him with the 2013 Excellence in Biomimicry Award. 

Thomas was the lead designer for Project Haiti, a pro bono partnership between the U.S. Green Building Council and HOK to design a LEED Platinum orphanage and children’s center in Port-au-Prince. He was coauthor for the Genius of Biome report, a biomimicry resource created by HOK and Biomimicry 3.8.

What is the Genius of Biome report?

“The Genius of Biome report came out of our strategic alliance with Biomimicry 3.8. It is a genius of place of the Temperate Broadleaf Forest, which covers the east coast of the US and stretches across Europe and Asia. It describes the strategies and designs adopted by living organisms and their ecosystem level relationships, and are intended to stimulate innovation and deep thinking about the unique challenges of the biome. We structured it around re-occurring challenge areas: water, energy and materials, and also social and economic categories because they are important to our clients and communities.”
