Tom and Ruth Harkin Center

The Harkin Institute was designed with sustainability in mind from start to finish, aiming for deep, measurable performance. A 67 kW photovoltaic array supports the building’s energy strategy, which targets a 73% energy reduction from a baseline of 120 EUI down to 34.5 EUI. Energy-saving features like high-efficiency heating and cooling systems, an energy recovery ventilator for fresh air, and smart lighting controls help reduce energy use while keeping the building comfortable. Large windows bring in natural light and offer views in more than 60% of workspaces. Ventilation is carefully managed with CO₂ sensors and well-designed air systems to maintain air quality and comfort.

To reduce water use, the building includes low-flow plumbing fixtures and doesn’t rely on permanent irrigation. Stormwater is collected and released slowly using special basins to prevent flooding. The team also focused on choosing long-lasting materials and tracked the environmental impact of construction materials through life-cycle assessments. Interior walls on the second floor can be moved to adapt to future needs, and recycling is supported by dedicated spaces and the university’s recycling program.

Indoor air quality was a priority, with low-emission materials, separate exhaust systems for certain rooms, and designs to limit drafts. Hot water systems were designed to prevent bacteria growth. MODUS carefully engineered all mechanical, electrical, and plumbing systems to meet the project’s ambitious sustainability goals. The building has been recommended for Three Green Globes certification and will continue to be monitored to maintain its high-performance standards.
