Ventilated facades have been identified as a viable solution to improve the thermal performance of buildings, thereby upgrading their energy efficiency. The literature points out a lack of studies on opaque ventilated facades among the different types of these facades. Thus, this study aims to present research on the thermal performance of opaque ventilated facades using a Systematic Literature Review (SLR), considering where the research was carried out, the method used and the main parameters that influence the thermal performance of these facades. The SLR proved efficient in outlining the desired panorama, indicating that this facade model consists of a technology only recently explored in academia with research concentrated in Europe, mainly in Spain, Italy and Portugal, highlighting the Mediterranean climate as the focus of the research. Most of the studies were conducted using computer simulations, followed by experimental methods that validated the mathematical models of the simulation programs. The SLR identified the outdoor conditions and aspects of the facade geometry that have a higher influence on the thermal performance of these facades. Considering the outdoor environment conditions, solar radiation and the year's seasons were the most discussed parameters in the literature. Considering the facade geometry, the ventilated facade openings (presence or absence of joints and grilles), the cavity height, and the outer skin material were the most studied variables.
