“…Aside from the three groups responsible for the research output on urban climate for Curitiba (there are three major research groups directly or indirectly related to topics on urban climate which are presently active in Curitiba, which are registered in the country's main directory of research groups [http://lattes.cnpq.br/web/dgp] -two of them are based at the Federal University of Paraná and the third is based at the Technological University of Paraná), all papers were written by one research group only (Technological University of Paraná), in some cases in international collaboration. 5,14,44,[47][48][49][50] Krüger and Givoni analyzed the influence of land use on intra-urban temperature differences in Curitiba from a small network of temperature/relative humidity weather stations during a 1-month period.…”

This review presents a summary of research in urban climate over the past decade and since the first reported studies in the field for Curitiba, Brazil. This city is located just south of the Tropic of Capricorn and has a long tradition in Brazilian urban planning. Due to increasing urban expansion in recent decades, quality of life within the urban area has been decaying (for example, in terms of the thermodynamic subsystem, which includes the development of urban heat islands). The integration of research outcomes and the development of the urban climate field in a more cohesive way could allow researchers to provide guidance for climate-responsive urban design, with consequential life-quality improvements in this location.

“…In Brazil, most of thermal comfort field studies was performed in urban outdoor environments (KRÜGER; ROSSI, 2011;LABAKI et al, 2012;MONTEIRO;ALUCCI, 2012;BRÖDE, 2012), whereas very few indoor thermal comfort studies have been carried out. The few existing databases comprise data from field experiments conducted in school and university buildings (XAVIER;LAMBERTS, 2000;LAZAROTTO;SANTOS, 2007;CÂNDIDO et al, 2010CÂNDIDO et al, , 2011CÂNDIDO;LAMBERTS, 2016), and one in military and commercial buildings (ANDREASI; LAMBERTS; CÂNDIDO, 2010).…”

DE VECCHI, R.; LAMBERTS, R.; CANDIDO, C. M. The role of clothing in thermal comfort: how people dress in a temperate and humid climate in Brazil. Ambiente Construído, Porto Alegre, v. 17, n. 1, p. 69-81, jan./mar. 2017 Occupants of two kinds of buildings (three offices and two university classrooms) assessed their thermal environment through 'right-here-right-now' questionnaires, while at the same time indoor climatic measurements were carried out in situ (air temperature and radiant temperature, air speed and humidity). A total of 5,036 votes from 1,161 occupants were collected. Results suggest that the clothing values adopted by occupants inside buildings were influenced by: 1) climate and seasons of the year; 2) different configurations and indoor thermal conditions; and 3) occupants' age and gender. Significant intergenerational and gender differences were found, which might be explained by differences in metabolic rates and fashion. The results also indicate that there is a great opportunity to exceed the clothing interval of the thermal comfort zones proposed by international standards such as ASHRAE 55 (2013) -0.5 to 1.0 clo -and thereby save energy from cooling and heating systems, without compromising the occupants' indoor thermal comfort.Keywords: Thermal comfort.

Resumo O isolamento térmico da vestimenta é uma das variáveis de entrada mais importantes utilizadas para prever o conforto térmico dos ocupantes dentro das edificações. Este artigo investiga padrões de vestimenta em edifícios com diferentes configurações localizados em um clima temperado e úmido brasileiro. Ocupantes de dois tipos de edifícios (três escritórios e duas salas de aula universitárias) avaliaram seu ambiente térmico através de questionários simultaneamente às medições microclimáticas internas in situ (temperatura do ar e radiante média, velocidade e umidade do ar

“…In terms of personal parameters, studies have found that women are more sensitive to thermal conditions than men (Krüger & Rossi 2011;Karjalainen 2007). In a more recent study, Kruger and Drach (2017) have identified gender effects to be insignificant whereas age was an important variable for open space users in Rio de Janeiro, Brazil.…”

A thermal comfort questionnaire survey was carried out in the high-density, tropical city Dhaka. Comfort responses from over 1300 subjects were collected at six different sites, alongside meteorological parameters. The effect of personal and psychological parameters was examined in order to develop predictive models. Personal parameters included gender, age, activity, professiontype (indoor or outdoor-based), exposure to air-conditioned space and sweat-levels. Psychological parameters, such as 'the reason for visiting the place' and 'next destination is air-conditioned', had statistically significant effects on thermal sensation. Other parameters, such as 'body type', 'body exposure to sun', 'time living in Dhaka', 'travelling in last_30 min', and 'hot food' did not have any significant impact. Respondents' humidity, wind speed and solar radiation sensation had profound impacts and people were found willing to adjust to the thermal situations with adaptive behaviour. Based on actual sensation votes from the survey, empirical models are developed to predict outdoor thermal sensation in the case study areas. Ordinal linear regression techniques are applied for predicting thermal sensation by considering meteorological and personal conditions of the field survey. The inclusion of personal and weather opinion factors produced an improvement in models based on meteorological factors. The models were compared with the actual thermal sensation using the cross-tabulation technique. The predictivity of the three models (meteorological, thermos-physiological and combined parameter) as expressed by the gamma coefficient were 0.575, 0.636 and 0.727, respectively. In all three models, better predictability was observed in the 'Slightly Warm' (71% in meteorological model) and 'Hot' (64.9% in combined parameter model) categories-the most important ones in a hot-humid climate.
