One Take #15 - Questioning the Questionnaire

Air Quality Matters ·

2025/08/28

Send us a text Have you ever wondered how researchers measure something as subjective as your comfort in a building? The latest episode of Air Quality Matters takes a surprising step back from specific pollutants to examine one of the most fundamental yet overlooked tools in indoor environmental research: the questionnaire. When scientists ask you to rate how stuffy a room feels or how comfortable the temperature is, they're relying on scales and questions that may be fundamentally flawed. M...
