Alabama A&M University is advancing sustainability and innovation in construction by becoming the first university in Alabama – and possibly the first historically Black college or university (HBCU) – to build a structure made of hemp. The University hosted world-renowned hemp builder Sergiy Kovalenkov for a two-day workshop that brought together architects, contractors, researchers, students, and community partners to explore the promise of hemp-based construction materials.

The workshop, held September 23–24 at AAMU’s Dawson Building, was organized by the Department of Transportation in collaboration with Hempire UA, a company co-founded by Kovalenkov in 2015. Hempire has gained international recognition for developing “Hempire Mix,” a carbon-negative hempcrete insulation that combines industrial hemp, water, and a natural lime-based binder. The material, known for its energy efficiency, durability, and environmental benefits, has been used in projects across Europe, Asia, and North America.

At AAMU, the inaugural hemp structure will serve as a center for electric vehicle bus drivers. “In our quest to reach a 100% Zero Emissions Transit System coupled with the University Green Initiative and carbon footprint reduction, this building will fulfill both objectives,” said Bulldog Transit System (BTS) Director Marshall Chimwedzi. “Design plans are underway, and we plan to begin construction in January with an expected completion date of December 2026.”

“This new lounge is a big win for our team,” added BTS Operations Supervisor Lei Hollingsworth-Jackson. It’ll give our 20 drivers a larger space to relax, prepare, and coordinate before and after their routes.”  

Kovalenkov, a civil engineer by training, was invited to campus through his connection with Dr. Ernst Cebert of the Winfred Thomas Agricultural Research Station (WTARS), which grows hemp and has been nationally recognized for its role in hemp seed characterization and cultivation. His visit to Huntsville follows a three-day conference at Cornell University and workshops at Oregon State University and the University of Louisiana at Monroe, underscoring AAMU’s place alongside leading institutions exploring hemp’s potential.

“This project places Alabama A&M on the forefront of sustainable building practices,” said Kovalenkov. “Universities play a crucial role in advancing this technology by providing spaces where research, data collection, and practical application can intersect. The fact that AAMU is embracing hemp construction signals both vision and leadership.”

Kovalenkov explained that hemp-lime, or hempcrete, is a natural insulation material that automatically regulates humidity, improves indoor air quality, and is resistant to fire, pests, and mold. “It replaces conventional insulation and drywall with a single material that is healthier for people and more sustainable for the planet,” he said. “For bus drivers working with electric vehicles, this lounge will even provide protection from electromagnetic fields, creating a healthier space for rest and recovery.”

Since founding Hempire UA in Ukraine, Kovalenkov has led projects in Denmark, Thailand, Australia, and the United States. His company remains active even amid the ongoing war in Ukraine, a testament to his commitment to sustainable innovation. He is also a co-founder of the U.S. Hemp Building Association and a frequent international lecturer on energy-efficient, green construction.

Attendees of the workshop included architect Joel Wasser of Nola VanPeursem Architects, PC, which is designing the new BTS hempcrete lounge. Wasser, whose firm is also building AAMU’s new Student Amenities building, said the project represents both a practical solution and a larger vision for sustainability in Alabama.

“They need a new place for the bus drivers and for people to eat between routes, and we’re going to use that need as an outlet to prototype this type of construction,” Wasser explained. “It ties directly into Alabama A&M’s agricultural mission, and it could be really sustainable while providing economic incentives for farmers in Alabama to grow hemp. We’re in a housing shortage, and being able to build quickly and sustainably with materials that can be grown locally could be a tremendous economic boost. We’re right at the cusp of something transformative here.”

Other participants included contractors from Management Enterprise Development & Services (MEDS) and AAMU alumnus Jeremy Jowers, a superintendent with Garber Construction who is currently overseeing the renovation of Patton Hall. Their involvement underscores the collaborative spirit of the project and its potential to influence local building practices.

Kovalenkov praised AAMU for taking bold steps in sustainable innovation. “The building planned for this campus will be the first of its kind in Alabama, and it shows real vision,” he said. “I applaud Alabama A&M for being on the forefront of this technology and setting an example for universities, architects, and city leaders across the nation.”
