Seminar 73 -- Thermal Stratification for Comfort, Air Quality and Energy Implication

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Thermal stratification caused by vertical temperature difference is highly related to occupants' thermal comfort, air quality and energy consumption of buildings. ASHRAE 55 and 62 specify the maximum allowed vertical temperature difference and ventilation effectiveness for stratified environments respectively. This seminar reports the latest results on how thermal stratification influences thermal comfort, air quality, and energy efficiency through laboratory human-subject and physical experiments, and field studies in lecture theaters. The design and operation challenges for stratified environments is discussed. The seminar also presents new guidelines and ventilation strategies to enhance thermal comfort, indoor air quality and energy efficiency.
