Time-Temperature Preferences (08-18-21)

Vellei  and colleagues studied how preferred air temperatures vary from one time of day to another.  They report that their efforts reveal “some evidence of a time-varying thermal perception by using: (1) data from about 10,000 connected Canadian thermostats made available as part of the ‘Donate Your Data' dataset and (2) about 22,000 samples of complete (objective + ‘right-here-right-now' subjective) thermal comfort field data from the ASHRAE I and SCATs datasets.

Temperature and User Comfort (07-27-21)

Ganesh and colleagues investigated how temperature influences user comfort.  They found via a literature review that “Improving indoor thermal comfort depends mainly on two major factors, air temperature, and air movement. . . . .  To improve IAQ and minimize the threat of cross-infection from various airborne diseases, the higher ACR [air change rate] at low airspeed should be used reliant on the occupancy capacity of the room.”  

Complex Effects in Offices (06-02-21)

Bourikas and colleagues report interesting relationships between perceptions of various aspects of office environments.  Their work indicates that “bad air quality is generally associated with a ‘warm’ thermal sensation response. . . .  air quality . . . and noise perception (NSV) are both correlated with thermal perception (TSV). . . . Air quality perception was correlated with both TSV  and NSV.. . .

Temperatures and Liking (05-05-21)

Erkan investigated how temperature influences “architectural liking.”   Study participants experienced “a virtual reality environment at three different temperatures (15°C, 22°C, 30°C). . . .  An EEG device was used to determine the cognitive activities of the participants during space navigation. In addition, an eye-tracking device was used in virtual reality goggles to identify the areas that participants were looking at. It was determined that the architectural preferences of the people changed depending on the temperature of the space. . . .
