5 Warm climates pose challenges to building energy consumption and pedestrian comfort. 6 Knowledge of the wind flow around buildings can help address these issues through 7 improving natural ventilation, energy use and outdoor thermal comfort. Computational Fluid 8 Dynamics (CFD) simulations are widely used to predict wind flow around buildings, despite 9 Researcher, Singapore-ETH Centre, Futur...

The outdoor wind comfort is important for evaluations of the urban environment. existing criteria are based on correlations between parameters, human activity levels, and level categories. These vary among different climates regions, they influenced by meteorological parameters adaptation. In this study, an questionnaire survey was conducted measurements were collected in Xi’an, which located c...

The strategies to reduce the consumption of non-renewable energies in buildings are becoming increasingly important. In the meantime, nature-inspired approaches have emerged as a new strategy to achieve thermal comfort in the interiors. However, the use of these approaches in architecture and buildings requires a proper understanding regarding the features of ecosystems. Although acquiring this...

PURPOSE Estimating wind chill index as one of the indexes effective in body comfort, specifically for athletes and tourists interested in winter sports. METHODS Meteorology data including temperature and the percentage of relative humidity of 6 synoptic stations of Chaharmahal-Bakhtiyrai province, Iran from 1990 to 2007 were extracted from Iranian Meteorology Site. In order to calculate the v...

The construction of a building inevitably changes the microclimate in its vicinity. Many city authorities request comprehensive wind studies before granting permit, which can be obtained through Computational Fluid Dynamics (CFD) simulations. Investigating conditions for 12 directions has previously been considered sufficient most literature and industry. However, effect changing number simulat...

This study investigated outdoor thermal comfort within 5 × idealized building arrays on five consecutive days by conducting unsteady computational fluid dynamic (CFD) simulations. The interacting effects of height topology, distance and layout airflow patterns, spatial distributions spatially averaged environment were evaluated UTCI (Universal Thermal Comfort Index). CitySim Pro was used to sim...

OBJECTIVES This report describes physiological and behavioural mechanisms behind the control of body temperature and thermal comfort during competitive singles tennis. METHODS Thermoregulatory responses and workload were observed during "best of three sets" tennis matches among 25 players. In total, 94 matches were played in ambient temperatures ranging from 14.5 to 38.4 degrees C. The therma...
