Materials selection and construction practices significantly affect IndoorEnvironmental Quality (IEQ). While there are many individual studies on theeffect of building materials on thermal comfort, day lighting, and other factors ofIEQ, further investigations are needed to study their effect on the Indoor AirQuality (IAQ) in hot arid climates, such as Egypt. Construction materialscontribute to the emission of air pollutants in indoor environments; consequentlyoccupants are exposed to multiple pollutants simultaneously as an apparentinteraction between the different types of construction materials and roomtemperature. Limited information is published on specific standards andguidelines for the IAQ considerations in Egypt.Human health and safety are two core values in sustainable development.Hence, the goal of this work is to investigate the impact of the built environment,namely, construction materials on IAQ. The study first identifies pollutantsources and their corresponding health impact due to short term and long-termexposure. The study also aims at quantifying the levels of a group of pollutants ata steady state controlled environment and to propose effective source controlstrategies for their reduction and possibly elimination. Field studies wereconducted during January and February in Cairo to monitor Volatile OrganicCompounds (VOCs), formaldehyde (HCHO), ammonia (NH3), radon gas andparticulate matter (PM2.5) and (PM10) activity. The indoor air is monitored innine locations, four during the construction process and five after the completionof construction. Chemical analysis and direct reading devices are used for airsampling and monitoring, in addition to recording indoor and outdoor relativehumidity, temperature and Carbon Dioxide (CO2) concentrations.The results of this work offer: recommendations to the types of materials that should be eliminated or improved to reach desirableIAQ conditions in hot arid climatic zones; and the development of an IAQ indexas an assessment method that compares the measured parameters to existingrecommended standards. The data gatheringchallenges are recorded and collected data is tabulated. The results of this study reveal a variation within therecommended benchmarks after the completion of construction and with the applicationof different finishing materials. The results also reveal that theconcentration of some pollutants decreased within the first year of construction,others have remained above target limits. The results contribute to the decisionmaking process among engineers regarding the selection of appropriate materialsto reduce negative impacts through the implementation of appropriate sourcecontrol strategies. Based on the conclusions and limitations of this study,recommendations for future work are documented.
