The purpose of this study is to design and evaluate a single-layer garment that incorporates different textiles to improve the physiological comfort of backpackers hiking in cold weather conditions. The objectives are to identify comfort needs, to design a prototype shirt, and to evaluate comfort and performance of the prototype over time, in comparison to a control. Qualitative data were colle...
The impacts of building envelope designs are significant on indoor thermal environment, especially for naturally ventilated buildings. Parametric façade studies were investigated for various orientations, window sizes and shading devices by using building simulation (ESP-r) and CFD (FLUENT) coupling program to predict indoor thermal environment in an accurate and quick way. Two typical weeks we...
The analysis of the winter and summer thermal behavior of a low-income dwelling, built by Provincial Institute of Dwelling in Salta, is presented. For both orientations of the major axis, the mean indoor temperatures in winter were around 14°C with a daily thermal swing between 5°C and 10°C, values that are outside the comfort area. Thus, auxiliary conventional heating is needed during all the ...
This dataset describe microclimatic parameters of two urban open public spaces in the city of Belo Horizonte, Brazil; physiological equivalent temperature (PET) index values and the related subjective responses of interviewees regarding thermal sensation perception and preference and thermal comfort evaluation. Individuals and behavioral characteristics of respondents were also presented. Data ...
Human thermoregulation is achieved via autonomic and behavioral responses. Autonomic responses involve 2 synchronous 'components'. One counteracts large thermal perturbations, eliciting robust heat loss or gain (i.e., sweating or shivering). The other fends off smaller insults, relying solely on changes in sensible heat exchange (i.e., skin blood flow). This sensible component occurs within the...
Indoor environmental conditions (thermal, noise, light, and indoor air quality) may affect workers' comfort, and consequently their health and well-being, as well as their productivity. This study aimed to assess the relations between perceived indoor environment and occupants' comfort, and to examine the modifying effects of both personal and building characteristics. Within the framework of t...
For this study, empirical data on the thermal comfort parameters (i.e. room space temperature, velocity and relative humidity) was collected for the computation of the PMV and PPD thermal comfort index for the three flat types. The study shows that wind ventilation has a great effect on the interior comfort condition. This is evident from the diurnal variations of PMV values. Majority of the da...
