چکیده
the assessment of the thermal bioclimate is based on the human energy balance and derived indices such as Physiologically equivalent temperature (Pet) or Universal thermal Climate index (UtCi). these two indices were compared over a period of ten year based on hourly data in a middle european city with a temperate climate. the analysis performed shows that the differences obtained result from the different thermophysiological settings of clothing insulation. for conditions with extremely high vapour pressure values, UtCi yields higher values than Pet, which could describe the thermophysiological stress more appropriately.

Comparison of selected thermal indices in the northwest of Iran
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...
متن کاملComparison of UTCI with Other Thermal Indices in the Assessment of Heat and Cold Effects on Cardiovascular Mortality in the Czech Republic
We compare the recently developed Universal Thermal Climate Index (UTCI) with other thermal indices in analysing heat- and cold-related effects on cardiovascular (CVD) mortality in two different (urban and rural) regions in the Czech Republic during the 16-year period from 1994-2009. Excess mortality is represented by the number of deaths above expected daily values, the latter being adjusted f...

The Achillea L. genus has a wide distributional range, and the differences in oil composition may be affected by different environmental factors such as soil mineral fertilization, the climate conditions and the culture site. To evaluate the effect of temperate climate on content and chemical combination of essential oil of Achillea filipendulina Lam, A. arabica Kotschy and A. eriophora DC., t...
متن کاملCooling Effect of Shaded Open Spaces on Long-term Outdoor Comfort by Evaluation of UTCI Index in two Universities of Tehran.
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...
متن کاملComparison of UTCI to selected thermal indices
Over the past century more than 100 indices have been developed and used to assess bioclimatic conditions for human beings. The majority of these indices are used sporadically or for specific purposes. Some are based on generalized results of measurements (wind chill, cooling power, wet bulb temperature) and some on the empirically observed reactions of the human body to thermal stress (physiol...
