Indoor Environmental Quality (IEQ) is a key indicator of the quality of the built environment and the health of its occupants. The purpose of this study is to investigate a range of IEQ parameters in buildings located in hot, arid climates, representing some of the recurring challenges in offices. The study aims to identify the main IEQ factors and their acceptable ranges, including light, thermal comfort, air quality and noise. An IEQ index is utilized (Wagdi et. al 2017) as a tool which assesses the predefined IEQ parameters in office buildings providing a rating scheme which aggregates the obtained readings. Data collected from offices located in Dubai and Cairo is used to assess the indoor environment against defined benchmarks. The full range of parameters was monitored in a group of office spaces and the obtained readings were used to compute the IEQ index. For this investigation, all offices were completely fit out and tests were performed after at least one month of operation. The recorded results demonstrate that with careful design and informed material selection, acceptable IEQ levels can be achieved. The results and application of the index aim to provide an assessment tool to optimize design and construction practices, ultimately improving employee productivity, comfort and health.
