Sorry forgot the thing most directly related to the article. Harvard did a study on air and cognition (Google Harvard cogfx) - here's the Gemini summary which tracks with my research:

Study 1 (Simulated Office): Participants in optimized "Green" and "Green+" office environments scored 61% and 101% higher, respectively, on cognitive function tests compared to conventional office environments.

Study 2 (Buildingomics): In a real-world analysis, occupants of high-performing, green-certified buildings had 26% higher cognitive scores and slept better than those in high-performing but uncertified buildings.

Home/Work Study: Researchers tracking remote workers found that suboptimal indoor temperatures and elevated CO₂ (indicating poor ventilation) directly harmed creative problem-solving and cognitive processing.
