The Correlation Between PMV and Dissatisfaction on the Basis of the ASHRAE and the McIntyre Scale — Towards an Improved Concept of Dissatisfaction

Abstract

This paper proposes a concept of dissatisfaction that is based on the correlation between the McIntyre and the ASHRAE votes of the ASHRAE RP-884 Adaptive Model Project — Data. The correlation shows that people who are voting with ASHRAE ·2 or beyond are not necessarily dissatisfied (which is the basic assumption of the classical PPD concept) and vice versa, that people who are voting between -1 and 1 are not necessarily satisfied with their thermal environment. The data set was divided into several factors (age, gender, building type, indoor conditions, outdoor temperatures) to analyze any dependencies of the preference on these factors. Processing the data finally lead to a predictive system that is — applied to the source data — a better predictor for preference than the PPD. This improvement needs affirmation by the application of the predictive system to an independent data set.
