the present study compared simple thermal indices and the indices derived from energy budget models in the northwest of iran. for this purpose, the air temperature, solar radiation, relative humidity, cloud, cover and wind speed of 13 meteorological stations in the northwest of iran during the  the period of 1986 to 2007 were selected for comparison. the results which were extracted using biokl...

BACKGROUND Workers in many industries are exposed to thermally stressful work environments. Protection of the health of workers without unnecessarily compromising productivity requires the adoption of a heat index that is both reliable and easy to use. OBJECTIVES To evaluate the Thermal Work Limit (TWL), in a controlled environment and under field conditions, against these criteria. METHODS...

The benefits of rooftop greening are ascertained in thermal perspective. It effectively reduces the near surface ambient temperature and the reflected irradiation from the rooftop slab, thus increasing the thermal comfort environment above the lawn and reduces the heat transferred through the rooftop slab. The former effect enables the potential usage of the rooftop spaces for human activity an...

The level of satisfaction with an environment differs among individuals, which may be caused by social, psychological and physical factors. One of the environmental factors affecting physical and mental satisfaction, is the thermal condition of space. In recent years, the importance of thermal comfort has been accentuated due to the climate change and global warming, increasing the number of st...

The purpose of this study is to propose a new outdoor thermal index that simultaneously indicates universal and separate effects. The value indicating universal effect in this index consists of the summation of air temperature and the effective temperature differences by air velocity, longwave radiation, solar radiation, and humidity. This paper describes the theoretical construction of this ne...

Considerations of urban microclimate and thermal comfort are necessary for development, a set guidelines comfortable must be developed. However, to develop such guidelines, the predictive ability indices outdoor perceptions under different design decisions defined. The present study aimed determine suitable assessing reaction in humid subtropical residential areas China. Five criteria coefficie...

Environmental matters are more complicated. Sustainability of environment requires an integrated approach to decisions making, planning, and management. Therefore, there is a need for a professional and systematic environmental management approach to reducing the consumption of resources. This approach is generally lacking in most universities, and therefore achievement of sustainability become...

The quality of outdoor spaces in a residential community affects the quality of life of its residents. This paper presents the findings of a study on outdoor thermal comfort and space usage at a residential community in Wuhan, central China, through the monitoring of microclimate conditions, interviews with residents, and recording of occupants’ activities. The data were used to develop a Therm...
