The lack of comparative energy performance studies to provide evidence based design guidelines for the proper use and design of traditional solar screens, in general, and massive perforated screens such as Jali, in particular, could result in their unsuccessful adoption to contemporary commercial buildings.
Examples of these perforated screens are Mashrabeya, Jali, and Guss-Walls.
According to the literature, nearly all the geometric designs used in Jali screens can be reduced to a series of competitively simple geometric shapes (Hill and Grabar, 1964).
It shows that applying Jali screens was correlated to better thermal comfort performance in both climates; with better thermal comfort indices for the 30% Jali screens as compared to base case (Figure7).
The Yemeni popular forces, and their allies captured Jabal Jalis on Tuesday after a violent battle with the Saudi-led Coalition in Southern Yemen, a military source said.
"The Ansarullah forces, backed by the Yemeni Republican Guard and former president Ali Abdullah Saleh loyalists, captured Jabal Jalis in Lahij province," the source said.
The source, demanding anonymity, added that the Ansarullah forces and their allies captured Jabal Jalis after an intense three day battle.
The capture of Jabal Jalis has positioned the Ansarullah forces and their allies within striking distance of the strategic Al-Anad Military Airport, which is currently under the control of the Saudi Army.
Saleh Ali Jalis, the new chef de cuisine at Mijana, was previouslyat the helm of sister property, The Ritz-Carlton Dubai's Arabic restaurant Amaseena.
Prior to moving to the UAE, Jalis spent six years with the Four Seasons Hotel in Saudi Arabia, where he started as a cook and rose through the ranks to the position of junior sous chef.
