In the upcoming period, city squares' urban redesign will be crucial in achieving sustainable development goals. This study presents a systematic review of OTC-related studies for the urban design of city squares using the PRISMA 2020 methodology. A review included a total of 173 papers from 2001 to 2023. The results identified five study types—clusters based on four pre-defined criteria: study approach, data collection methods, time duration, and primary objectives. The clusters indicate that more than half of all studies are related to the comparison of thermal comfort and heat mitigation measures. Most of the case studies were located in one of three climate zones: temperate oceanic (Cfb) (58 studies), hot summer Mediterranean (Csa) (40 studies), or humid subtropical (Cfa) (28 studies). The most common geometry of the analyzed urban square is medium-sized, is rectangular, and has dominant axel orientation south–north. Also, based on all five clusters, several research gaps were identified, appropriate for future research: the majority of studies related to the traditionally considered climate areas, no typology of urban square geometry configuration based on OTC assessment, and the lack of a local design model for assessing and improving the thermal comfort of city squares.

The objective of this study was to carry out the financial feasibility analysis of harvesting rainwater from permeable pavements in a city square. A case study was carried out in a square close to the beach in the city of Florianópolis, Brazil. Questionnaires were applied to pedestrians who circulate within the area. The square is to be implemented to promote sustainability and improve the user's quality of life. From the rainfall data and the average daily water demand for irrigation of the square vegetation, the volume of rainwater to be harvested from the permeable pavement was calculated. The rainwater demand was estimated as 662 L/day. The implementation and operation costs of the pavement and irrigation systems were evaluated. The potential for potable water savings was 89.8%. The payback period was estimated as 347 months. This study showed that rainwater collected from permeable pavements is financially feasible and represents a promising technique.

Litewski Square is widely known as the place where the Lithuanian envoys camped to attend the Union Sejm in 1569. Today, Litewski Square represents a space of transformation. The urban public spaces of the square have been rebuilt several times, each instance delineating a distinct rendering of tradition and history. In this article, the evolution of the square is presented in order to analyse three main aspects. Over the years and under changing political conditions, its meaning, role, and function have shifted. Traditions and symbols that shape the space of the square have changed; these changing symbols have influenced how the meaning and functionality of the square have evolved over time. The research methodology of this paper is based on historical and interpretative studies. This form of analysis made it possible to identify the successive stages of the transformation of Litewski Square and, accordingly, in the context of changing political conditions, identify the elements that are important for the meaning of the square today. Litewski Square has evolved from an urban space with a clearly defined function to a multifunctional public space: from a memorial square into a modern space of leisure and entertainment. This paper argues that the accumulation of commemorative elements and directly adjacent recreational spaces give the impression of a lapidary, the constituent elements of which devalue each other. What this means is that, even as the number of commemorative symbolic elements have increased, their status is degraded, as well as that of Litewski Square as a whole. [ABSTRACT FROM AUTHOR]
