Abstract

In the last years there is a strong interest for application of bioclimatic techniques and practices in urban neighborhoods and open spaces. This paper presents a bioclimatic study of an open space in an urban area by the use of simulation tools giving emphasis on the replacement of conventional materials with cool materials. Routes linking traditional monuments in the Greek city of Florina are characterized of decreased human thermal comfort conditions during summer time. The employment of computational fluid dynamics has contributed in the understanding of what interventions should be made on urban populated routes in order to meet defined thermal related targets during the warmest day of the year. The proposed replacement of conventional materials by "cool" ones would result in the reduction of the mean surface temperature by 3.52°C while the mean maximum air temperature would be reduced by 1.39°C during noon of the warmest day.

Abstract

AbstractThe scope of the research described in this paper is to develop, evaluate and propose a newempirical index, the so-called Index of Workplace Comfort (IWC), which quantifies the overallcomfort sensation of a user in an office building. The proposed Index of Workplace Comfort is calculated on the basis of both environmental and psychological properly weighted sensation votes of workplace occupants. The weight of 13 variables in the equation of IWC is determined through ordered probit regression in a dataset, using a background questionnaire completed by 238individuals working in 11 office buildings. The evaluation of the proposed index consisted of the implementation of the IWC model in a building (52 cases) and the comparison with data collected from thermal comfort measurements based on ISO 7730 (159 cases) and thermal sensation votes of the occupants (321 cases). The findings show, with statistical significance, that the IWC describes the overall comfort conditions better than the PMV-PPD model used in ISO 7730 andsupports the position that psychological variables affect the overall comfort sensation of individuals in a workplace.
