Research conducted in Eurac Research’s terraXcube, an extreme environment simulator, indicates that the human sensitivity to temperature variations is less than one degree Celsius.
The recent experiment was conducted by Laura Battistel and involved four climate chambers with temperature control set between 23 and 25 degrees
The idea of studying human sensory capabilities using the terraXcube was the brainchild of Massimiliano Zampini, a full professor at CIMeC, University of Trento. The goal of this research is to find out what we can perceive about the environment around us.
Only in this way, can we deepen our knowledge of how the environment influences the way we think and act. In this sense, the study fits into the line of research on “Grounded Cognition,” the scientific theory according to which the cognition we have of our surroundings is inseparably linked to our sensory perception of the world itself. In other words, according to this theory, when we reflect, try to recall a lived experience or approach our surroundings, our senses are activated and they influence our thinking.
Implications for Building Climate Control
The results of the study have potential implications for the heating, ventilation and air conditioning sector in buildings. “From the perspective of energy sustainability, being able to determine a temperature range in which the individual maintains their state of comfort while reducing the building’s energy load would benefit us and the planet,” explains Riccardo Parin, supervisor of Battistel’s work.
“In our study, however, we do not focus on participants’ thermal comfort. In fact, we are currently more interested in finding out how our perception changes at temperatures higher or lower than those generally considered comfortable. And this is what we will be investigating in future experiments”, Parin concludes.
“Our infrastructure is made available for research in a wide variety of fields. From clothing to emergency medicine in the mountains, from the automotive industry to climate change,” says Christian Steurer, director of terraXcube. “The idea of conducting research on the human psyche inside our climate chambers intrigued me right from the start. Now the project is starting to bear fruit. I am looking forward to the next developments.”
