The objective of this study was to find correlation between thermal comfort, productivity workers and architectural variables of naturally ventilated offices. The proposed issue was: what are the architectural variables of naturally ventilated office environments can interfere on of comfort's variables influencing worker productivity? The theoretical framework involved the topics: thermal comfort, architecture of the buildings, ergonomics and performance evaluation. The methodological approach used was cross-sectional study of an applied nature, quantitative, descriptive and exploratory making a causal analysis by a case study. In collecting data we used two instruments to measure thermal variables two subjective evaluations, one to measure the thermal comfort and the other to measure the subjective worker productivity, and samples physical dimensions of the built environment where each worker played their tasks. The sample consists of 4 companies, 10 architectural environments and 25 office workers conducted 45 reviews in different time periods. Statistical analysis involved the identification of outliers; normality and correlation between variables. As results, 2% of yield values can be explained by the thermal comfort levels calculated. The correlations between the architectural variables and the thermal comfort variable showed low correlations, and the one that was statistically significant was the percentage of glazed window that were associated in 36.7% to the calculated thermal comfort values, the other correlations were 7.2% with the variable volume of space, 17.3% with external wall area of 0.20 m thick, 15.5% with the implantation of space using non-parametric analysis and 0.0% using parametric analysis. The correlations between the architectural variables and productivity also showed low values, being 1.9% with the implantation of space variable, 5.7% with the volume of space, 21.9% with the variable percentage of external glazed window, the area outer wall of 0.20m was associated in 48.3% the workload values reported by respondents, and this was statistically significant but empirically not logical. Although the correlations are not significant, it is not possible to say that the architectural variables naturally ventilated office environments, researched, are able to interfere with the thermal comfort variables to interfere in worker productivity, this paper presents results as the workload values had higher variation when workers were under discomfort by cold or heat (+/-14. 50%) than when they were in comfort levels between -0.5> PMV <+0.5 (+ / -8.50%). This shows that the comfort level interferes with productivity, but it is unknown how and how much. |
