The thermal environment outdoors affects human comfort and health. Mental and physical performance is reduced at high levels of air temperature being a problem especially in tropical climates. This paper deals with human comfort in the warm-humid city of Guayaquil, Ecuador. The main aim was to examine the influence of urban micrometeorological conditions on people's subjective thermal perceptio...

Green infrastructure can improve thermal comfort in outdoor urban spaces in moderate climates. The impact of green spaces on thermal comfort is often exclusively investigated through meteorological variables and human-biometeorological indices. Yet, studies on perceived thermal comfort are scarce. As thermal comfort is a property of human perception of the thermal environment, this knowledge is...

Subjective thermal comfort plays a critical role in body temperature regulation since this represents the primary stimulus for behavioral thermoregulation. Although both core (Tc) and skin-surface (Tsk) temperatures are known afferent inputs to the thermoregulatory system, the relative contributions of Tc and Tsk to thermal comfort are unknown. We independently altered Tc and Tsk in human subje...

Environment friendliness and energy efficiency are the mantra of today’s world in each and every sector of development. The automotive industry is also now switching to zero emission car concepts to be in congruence with this concept. During this transformation, however, consumer satisfaction should not be hampered. The consumer is satisfied if he feels comfortable using a given commodity. Comf...

The properties of gas mixture exert a large effect on thermal exchange from the human body and finally on the comfort temperature in the hyperbaric environment. Equations describing density, viscosity, specific heat capacity, thermal conductivity of real gas mixture as the function of helium contents, temperature and the total gas pressure were derived. It makes possible to improve the comfort ...
