Joshua Hatch
Sustainability expert on award-winning data centers
30, Senior Sustainability Advisor & Director of Sustainability Analytics
Brightworks Sustainability Advisors
Portland, Ore.

As an engineer with a foundation in biological sciences, Josh Hatch brings nature's insights to the design table. With a bachelor's degree in biological and environmental engineering from Cornell and a master's in civil and environmental engineering from Stanford, Hatch seeks to go beyond the traditional emphasis on solutions that are structural in nature and dependent upon inorganic materials. After graduate school, he worked at the Rocky Mountain Institute, focusing on the issue of energy use in, and carbon emissions from, the built environment. At RMI, Hatch served as beta developer of the Green Footstep carbon footprinting tool for buildings. Since joining Brightworks Sustainability Advisors in 2006, Hatch has worked on several notable data center projects, including serving as green building program manager for Facebook on its Prineville, Ore., Forest City, N.C., and Lulea, Sweden, data centers. Hatch has also managed sustainable design programs for data centers for such companies as Yahoo!, VMWare and Equinix. He originated a new line of business within Brightworks–called sustainability analytics—to meet the growing demand from clients for help with understanding environmental issues associated with corporate actions that fall outside the domain of conventional decision-making frameworks.
