Abstract
The use of atrium in highrise buildings with large dimensions is a common way for illuminating internal central spaces. Failure to pay attention to the effective factors of climatic design in atriums can lead to poor lighting and thermal performance of interior spaces.
The research question is what is the most appropriate distance of the interior spaces from the atrium well? The main purpose of this research is to answer this question.
The ratio of internal spaces distance from the atrium well (the depth of the balcony) to the height of the floors in 4 different states with 1/2, 1/1, 2/3 and no atrium balcony (immediate space) are considered. Annual Dynamic daylight factors such as (sDA300/50%), (ASE1000/250), (UDI100-2000) through a simulation approach by (Design Builder v6) software were obtained.The interior temperature of the hottest and coldest days of the year is calculated in (fluent).
In conclusion ... on the northern side of the atrium, the most suitable position of interior spaces for first to third floors is the immediate distance from the atrium well. In addition, on the fourth or last floor, the best position is when the distance from the atrium well is equal to the height of the glazed partition. On the southern side of the interior of the atrium, the placement of spaces for the first and second floors is also better in the immediate area, but for the third and fourth floors, the best distance is when the balcony depth is half of the floor height.
