Effect of urban geometry and spacing on the thermal performance in the Mediterranean climate of the Gaza Strip

الملخص EN

This paper studies the thermal performance of different forms of the housing units located in the Mediterranean climate of the Gaza Strip and within different urban configurations.

The paper is carried out using the computer programs ECOTECT and IES.

The results indicate significant thermal effects due to the urban geometry.

The paper concluded that the spacing ratio (L1/L2) equals 0.1 and aspect ratio (H/W) equals 0.5 is the preferable option in the (E-W) street in the Gaza Strip.

However, the more preferable option in the (N-S) street has a spacing ratio (L1/L2) equals 1.2, and aspect ratio (H/W) equals 4.0.

Therefore, Building’s proportions have to be determined with a full understanding to their relations with the urban morphology.

It is also recommended to utilize the advantages of the mutual vertical arrangements of building in achieving shading on the roof and building’s façades by using different heights of buildings.
