Honorable Katherine Hammack serves as Director of Special Projects at the GBCI. She rejoins USGBC family after having worked as one of the founding members over 30 years ago. She has many years of experience in energy, sustainability, utility and infrastructure operations, and is delighted to come back to help advance tools to improve the built environment. A graduate from Oregon State University with a degree in Mechanical Engineering as well as a Masters in Business from University of Hartford, Hon Hammack couples a strong background in energy and engineering with her goal of building a better working world for future generations. Katherine serves on numerous boards and advisory committees, including ASHRAE Board of Directors and the Board of Directors of Slipstream, a non-profit organization that creates, tests, delivers and scales the next generation of energy efficiency and renewable energy programs that move us farther, faster toward a clean energy economy. Hon. Hammack was appointed by President Obama as the Assistant Secretary of the US Army for Installations, Energy and Environment in 2010. She served in that capacity, through 2017, with responsibility for policy development, program oversight, outreach, and coordination of a wide variety of Army activities overseeing all of the Army’s installations. Under her leadership, the Army instituted a net zero program for energy, water and waste. This program focused on efficient and effective resource management, on Army bases, to increase resiliency and reduce operating costs. She initiated the Army’s renewable energy program to increase resiliency and readiness of Army installations through on-base power production, microgrids and energy storage initiatives. She also implemented programs to double the number of energy savings performance contracts in the Army. Hon. Hammack’s career includes work in sustainability consulting, for several electric utilities, manufacturing and product management.
