Simulation For New Methodology Of Legislation On The Setback Of Residential Buildings In The Hilly Areas Of Amman (Jordan)

Abstract

The aim of this study is to create the conditions necessary to obtain the right amount of solar radiation and ventilation in the buildings located in the hilly areas of the city of Amman (sloping land). By examining these areas, we have found that the main problem is that many residents suffer from diseases, allergies or show general symptoms of discomfort due to staying in unhealthy homes, in which we have found a very high humidity level, caused by insufficient or absent ventilation and by general conditions that severely limit access to sunlight.

The methodology adopted for our study is based on several environmental simulations, using the Revit software, to obtain the best design compatible with the life of man, with his activities and with the natural environment. A first simulation applied to buildings, evaluates the shadows at different times and seasons of the year; the second simulation evaluates the correct adjustment to the distance between buildings (setback), based on their height and the slope of the ground, to obtain sufficient sunshine and ventilation and reduce the shading caused by the projection of the shadow on the adjacent buildings.The conclusion of our study consists in the proposal of a new legislation on the setback of residential buildings in the hilly areas of Amman (Jordan).
