The 23,000-square-foot building now functions as a real-world case study in deep energy retrofits. Instead of relying on offsets or marginal upgrades, the project prioritized all-electric systems, high-efficiency design, and on-site renewables. The result is a workplace that operates without fossil fuels, delivers strong energy performance, and maintains the architectural character of its industrial past.
Pepper’s renovated headquarters recently achieved ENERGY STAR NextGen certification from the U.S. Environmental Protection Agency—a recognition that reflects both low operational emissions and significant renewable energy sourcing. This designation, introduced by the EPA to highlight buildings that exceed traditional efficiency standards, requires facilities to meet several benchmarks: an ENERGY STAR score of at least 75, strict emissions limits, and a high percentage of renewable energy use—either 30% of total energy or 100% of electricity.
The Cincinnati office exceeded every threshold, scoring a 96 and sourcing all its electricity from renewables. It also operates with zero direct emissions per square foot. These achievements reflect deliberate design choices, including a geothermal system, on-site solar panels, and optimized daylighting strategies that improve both energy efficiency and employee comfort.
Beyond ENERGY STAR, the building has earned multiple certifications that reinforce its performance and health-focused design. In 2025, it received LEED Zero Energy status, making it one of the oldest buildings in the country to reach that benchmark. It also holds LEED Gold and WELL Gold certifications—recognizing both environmental metrics and workplace wellness.
This layered approach demonstrates how integrated design can deliver on multiple priorities: decarbonization, occupant health, and long-term cost efficiency. For Pepper, the project offers a replicable model for clients looking to retrofit aging properties without compromising on climate goals or user experience.
