Hammell, Green and Abrahamson (HGA), the national design firm that celebrates its 65th anniversary this year, has moved forward on its strategy to elevate its sustainable design and energy planning proficiencies by acquiring Sustainable Engineering Group (SEG), an engineering firm based in Madison, Wis., effective July 1.

SEG, which was founded in 2004, has established itself as a regional leader in energy systems modeling, commissioning and retro-commissioning, LEED certification, and advanced research. It specializes in geothermal systems, renewable energy systems, and carbon reduction/net-zero campus planning.

By adding SEG to its stable, HGA is reinforcing its expertise in energy and infrastructure planning and design for national clients in healthcare, academic, corporate, and public sectors.

“SEG’s approach and deep knowledge will allow us to better serve the energy needs of our growing client base,” says Rick Hombsch, PE, LEED AP, vice president and HGA’s Energy & Infrastructure market leader. “Their team brings technical insights into emerging energy technologies and renewable resources that build on our existing strengths.”

Among SEG’s noteworthy projects are the 8,000-sf Outgamie County Regional Airport in Appleton, Wis., for which SEG provided energy modeling and life-cycle cost analysts for this ZNE building; and UW Hospitals and Clinics, which retained SEG to provide retro-commissioning services for its 3.6-million-sf campus in Madison.

SEG is changing its name to HGA, and merging its operations. Its employees are staying on with the firm, as are SEG's founders, Manus McDevitt, PE, LEED AP; and Svein Morner, PE, PhD, LEED AP, who will be principals at HGA. With the addition of SEG, HGA has offices in 10 cities across the U.S.
