In hot arid regions like the UAE, it is of the utmost importance to evaluate and determine the best building orientation. Consequently, the aim of this paper is to investigate thermal performance of building orientations in the UAE. In order to test the thermal performance of building orientations in Sharjah, a real lab-scale house was constructed. It was divided into two zones; one oriented toward the north (M1) and the other one was oriented toward the south (M2). An infrared (IR) camera generated thermographs of each orientation (on one day) and average mean temperatures were recorded over 5 months. The Temperature Difference Ratio (TDR), Time Lag (T_g), and Decrement Factor (DF) were tested. It was concluded that: (1) The south orientation had a 9.4% higher temperature than the north orientation; (2) M2 had 3% higher outdoor humidity; (3) M2 had a DF that was 0.01° higher than M1; (4) M1 had a TDR that was 0.162° higher than M2; (5) M2 had an average time lag (H) that was 1.838 h lower than M1. The paper also reveals more interesting findings, which were analyzed, thoroughly tested and discussed.

在像阿联酋这样的炎热干旱地区，评估和确定最佳建筑方位至关重要。因此，本文的目的是研究阿联酋建筑物方向的热性能。为了测试沙迦建筑方向的热性能，建造了一个真正的实验室规模的房屋。它分为两个区域。一个朝向北方（M1），另一个朝向南方（M2）。红外（IR）相机在5个月内记录了每个方向（一天）和平均平均温度的温度记录图。温差比（TDR），时滞（T _g），并测试了递减系数（DF）。结论是：（1）南方位比北方位高9.4％。（2）M2的室外湿度高3％；（3）M2的DF比M1高0.01°；（4）M1的TDR比M2高0.162°；（5）M2的平均时滞（H）比M1低1.838 h。本文还揭示了更多有趣的发现，并对这些发现进行了分析，全面测试和讨论。
