The results are analyzed and based on the evaluation standard for greening building of China. The simulation method is discussed in detail, and some suggestions for wind environment optimization are put forward, which might be helpful for similar research.展开更多

Researcher has developed a number of assumptions that helps to resolve the research problems, which includes the application of the indoor environmental quality and will highlight the required design standards of it to provide a healthy environment to the houses and chosen AREE （Aqaba residence energy efficiency） as a case study. The theoretical part goes through a brief study to definition of the required design standards which includes eight kinds of issues： indoor environmental quality intents, control of environmental tobacco smoke, control of chemicals contaminants, design well ventilated buildings, provide daylight/view, energy efficient lighting, thermal comfort, consider acoustics and its uses in all the elements of internal spaces. Than we going through the uses of these requirements by using descriptive analytical approach, we chose one case study （AREE）. To analyze the uses of their requirements of the indoor environmental quality and we also collect the information about this house from the owner of the AREE, then draw conclusions and list of references.展开更多
