With the spread of sustainability concepts, due to global energy crisis and unrestrained consumption natural resources, importance rational use reduction has been intensified, albeit in short steps. This concern taken up bioclimatic concepts buildings, especially housing buildings for low-income people, aiming at improving quality production terms its habitability. The objective this research i...

This study aims to use vernacular climatic solutions (VCS) of traditional dwellings of Bushehr in common residential buildings of this city in southern Iran and answer to the question that “What is the effect of VCS in terms of energy consumption in these buildings?”. This research was conducted on two levels. At the first level, after selecting an existing model of common residential buildings...

Passive solar systems such as solar chimneys need solar radiation in order to work. Therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. Phase change materials can save additional thermal energy during the day and release it during the...

this paper is an attempt to numerical modeling and experimental study of air flow in the yazdi wind-towers. wind towers has been known as one of the most effective climatic elements in iranian traditional architecture. this paper is an attempt to evaluating yazdi wind-tower to discussion the two main questions: 1. what is the role of orientation of wind-towers span, regarding to climate and hei...

The residential natural ventilation rates have a significant impact on indoor thermal comfort and air quality building energy consumption. characteristics of the indoor-outdoor temperature difference wind pressure change over time, as well occupants' window opening behavior use HVAC systems, resulting in rate being dynamic with time. Many previous studies measured steady-state rates, which does...
