	abstract = {Three different clothing thermal resistance (r cl) schemes are compared using meteorological and human data collected in Martonvásár. Model 1 is the most complex, it is energy balance based. Model 3 is the simplest, it is the UTCI-clothing model used as submodel in the UTCI (Universal Thermal Climate Index) scheme. It uses air temperature as sole input. Model 2 uses more data than model 3, the data used are the thermal insulation values of the clothing worn. Meteorological data refer to the town Martonvásár. The data were collected in the period August 9, 2016-May 23, 2018. The main result is that the r cl values obtained by model 1 differ significantly in most of the cases from the results obtained by models 3 or 2. The fact that the results of model 1 rarely match the results of model 3 or model 2 suggests that the energy balance between human body and environment is rarely achieved, merely this is the case in approximately 10 percent of the cases.},

	abstract = {Human thermal climate in the Hungarian lowland is investigated by using a clothing resistance-operative temperature model performing individual, local, and long-term concurrent observations of weather and human thermal perception. Human thermal load is characterized in terms of clothing resistance r(cl) and operative temperature T-o. The model is also used as a tool to analyse the relationship between r(cl) and the structural parameters of the body (relative fat mass index (fatBMI) and relative muscle mass index (muscleBMI)). This analysis works with data collected on more than 1,000 occasions of weather and thermal perception observation and uses body structure data of more than 3,000 adults and children. By analysing the data, the following human thermal climate characteristics have been established. (a) T-o of about 80 degrees C can be considered as the upper limit of heat stress in the Hungarian lowland, similarly, T-o of about -35 to -37 degrees C can be taken as the lower limit of cold stress. (b) Interpersonal thermal load variations increase with increasing of cold stress; these variations are the smallest within the "thermoneutral" zone. (c) In cold stress situations, there is a significant sexual dimorphism in the relationship between r(cl) and fatBMI. (d) In night time period of the day, T-o can vary between 25 degrees C and the lower limit of cold stress. In this range of T-o, thermal perception types "neutral," "cool," "cold," and "very cold" occurred. Based on the results, it can be seen that interpersonal thermal load variations cannot be neglected in extreme cold weather conditions, and that interpersonal variations of fatBMI index are determinant in the formation of individual clothing resistance.},

	abstract = {A new statistical deterministic model is presented for estimating human thermal load and sensation. Human thermal load is simulated in terms of clothing resistance ( r cl ) and operative temperature ( T o ). The model’s input data are wind speed, air temperature, mass of the human body, body length, sex, age, and the latitude of the site. T o is statistically linked to potential evapotranspiration, whilst human thermal perception to r cl . The model has been validated in the Carpathian Mountains region for the period 1971–2000 comparing it with the original deterministic r cl model. Thermal perceptions of the representative Hungarian male and female are estimated by using individual thermal perception– r cl point clouds. Metabolic heat flux density differences between persons are less than 15 Wm −2 . Human thermal perception area distribution has a topography-based configuration. The prevailing annual perception of Hungarians (for both men and women) in lowland and hilly areas is “cool,” although “neutral” may also occur; in mountains, perception is mostly “cool” or “cold,” with “very cold” being also possible. In the month of July, the perception type in mountains is “neutral” or “cool” depending on the person. In lowland areas, the methodology cannot be applied since the energy balance is not met. The model can also be applied in other heat-deficient regions if the region-specific operative temperature–potential evapotranspiration and the human-specific thermal perception - r cl statistical relationships are determined for the new region.},

	abstract = {A new clothing thermal resistance scheme is presented and verified for the Carpathian region and for the time period 1971–2000. The scheme is as simple as possible by connecting operative temperature to air temperature, which allows for it to only use air temperature and wind speed data as meteorological inputs. Another strength of the scheme is that a walking person’s metabolic heat flux density is also simply simulated without having to regard any thermoregulation processes. Human thermal load in the above region is characterised by a representative adult Hungarian male and female with a body mass index of 23–27 kgm−2. Our most important findings are as follows: (1) human thermal load in the Carpathian region is relief dependent; (2) the scheme cannot be applied in the lowland areas of the region in the month of July since the energy balance is not met; (3) in the same areas but during the course of the year, clothing thermal resistance values are between 0.4 and 1 clo; (4) clothing thermal resistance can reach 1–1.2 clo in the mountains in the month of July, but during the course of the year this value is 1.8 clo; and (5) the highest clothing thermal resistance values can be found in January reaching about 2.5 clo. The scheme may be easily applied to any another region by determining new, region-specific, operative temperature–air temperature relationships.},
