During building design there is a growing need to reduce energy usage whilst maintaining the comfort of the occupants. The latter is referred to as ‘thermal comfort’ and can be measured by the extent that the internal temperature of the building does not exceed a specified comfort level. Traditionally these two measures of building performance are seen as a trade off. Moreover, energy efficient...
Designing for indoor thermal environmental conditions is one of the key elements in the energy efficient building design process. This paper overviews the investigation of thermal comfort conditions in China and relevant energy efficiency issues. A development of the Chinese evaluation standard for indoor thermal environments based on intensive field and laboratory studies has been introduced. ...
Introduction: Climate conditions are the most important factors affecting human activity on short- and long-term scales. The study of the effect of climate conditions on human life and behavior investigate in the branches of science called human bioclima. The condition of comfort is a set of conditions that, in terms of heat and humidity, at least 80% of the individuals randomly selected and pl...
The ‘wind-rain’ house has a courtyard with glazed roof, which allows more direct sunlight to come into indoor spaces during the winter. The glazed roof can be partially opened or closed and automatically controlled to provide natural ventilation in order to adjust for indoor thermal conditions and the roof area can be shaded by reflective insulation materials during the summer. Two field studie...
current standards for indoor comfort are based on studies of adults, but they also apply tochildren, even though children differ in terms of metabolic rates, clothing types, activity levels, and preferences in space arrangement. children are also more sensitive to a range of environmental factors, they are usually unable to interact with their environment, and they accept indoor conditions pass...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
Because of the differences between indoor and outdoor thermal condition, preparing some outdoor thermal indices is a way to understand and categorize the outdoor thermal sensation. The aim of these indices is not to provide thermal comfort - as it is the aim of indoor indices. Instead, they are provided to analyze outdoor thermal sensation to help architects, landscape architects and urban desi...
The mosque has served as a ritual space for Muslims since the emergence of Islam; in every era it has been designed and constructed based on terms and conditions of performance and the technology. But there are almost some fixed and unchanged elements that distinguish the mosque from the other places. In the mosque architecture, the dome is considered as an important symbol and element, and in ...
Due to the complexity of built environment, urban design patterns considerably affect the microclimate and outdoor thermal comfort in a given urban morphology. Variables such as building heights and orientations, spaces between buildings, plot coverage alter solar access, wind speed and direction at street level. To improve microclimate and comfort conditions urban design elements including veg...
