one of the predictions of the L he adaptive hypothesis is that inhabitants of warm climates prefer warmer indoor temperatures than inhabitants of cold climates. This contradicts the static assumptions underlying the current ASHRAE 55-92 comfort standard. Examine the adaptation hypothesis and its impact on ASHRAE Standard 55-92

WWhat should you know about adaptive thermal comfort?

“The adaptive comfort model has become the global standard for building design and operation and has led to energy savings around the world. How to Quantify Thermal Comfort In ASHRAE 55, there are three main methods to see how the space and the system are designed according to the standard thermal comfort:

The adaptive approach to thermal comfort modeling can fully account for thermal adaptations, but ignores the thermal balance of the body. In order to predify thermal comfort verbatim, this study was ...

Thermal comfort: research and practice - PubMed

As part of the first theme, PMV ( Predicted Mean Vote), created by Fanger in the late 1960s, is discussed in light of the emergence of adaptive thermal comfort models. Adaptive models are based on the adaptive capabilities of the occupants and address the possibilities for personal control of indoor climate, comfort and performance.
