This research paper discusses the sustainable planning and design principles in the investment in residential complexes in Iraq, especially the five principles of UN-habitat. The research problem emerged in the lack of knowledge and local studies in Iraq about sustainable approaches to investment in residential complexes at the planning and design level. This research aims to shed light on the application of the five principles of UNhabitat to residential complexes, and proposes treatments to achieve integrated environmental sustainability for investment in residential complexes. The current research focuses on environmental sustainability of the proposed new residential investment projects in Baghdad Iraq Gate Residential Complex (high-rise residential complex) and Badour Residential Complex (low-rise residential complex). Indicators were extracted from previous literature and selected samples, and the research investigated the extent to which these indicators converge with the five principles of UN-habitat adopted. The results indicated that each of the two complexes achieved only one of the five principles, which requires highlighting the importance of applying the concepts of sustainable development in residential investment complexes in Iraq. Keywords: Environmental sustainability, UN-habitat principles, Residential investment complexes, Iraq gate residential complex, Budour residential complex, Iraq.
