Yes — the evidence is specific. Research from Harvard T.H. Chan School of Public Health found that employees in buildings with superior ventilation achieve a 26% increase in cognitive function. The mechanism is CO₂ concentration: in inadequately ventilated enclosed spaces, CO₂ rises to approximately 1,000 ppm within 30–45 minutes, at which level measurable declines in decision-making quality, response speed, and sustained attention occur. HIGHKA’s dual-channel turbine ventilation, active throughout occupancy, prevents this accumulation during extended focus sessions — maintaining the air quality that supports sustained cognitive performance rather than allowing it to degrade as a session progresses.
