Abstract

The Predicted Mean Vote (PMV) is widely acknowledged as the quintessential model for assessing thermal comfort in indoor environments on a global scale. Its empirical validation has sparked debates regarding the applicability and dependability of the model within real-world building contexts. This paper initially presents the fundamental principles of the PMV model, encompassing its mathematical formulation, influential variables, and criteria for thermal comfort assessment. Subsequently, a comprehensive classification and review of the PMV model is conducted with respect to office buildings, residential spaces, educational institutions, healthcare facilities, fitness centers, religious structures, and commercial complexes. Finally, detailed descriptions of several extended PMV models (ePMV, aPMV, and nPMV) are provided. This paper aims to assist architectural designers and HVAC system operators in navigating the intricate and diverse landscape of standards related to thermal environments. The ultimate goal is to enhance indoor environmental quality and energy efficiency.
