The current paper addresses the issue of how the use of technology may influence sustainable construction in Iraq with the focus on the balance between environmental and economic sustainability, local contextual issues, and the maintenance of architectural heritage. Taking into consideration the climatic and economic limitations of Iraq, sustainable construction as the way of increasing energy saving and decreasing environmental destruction becomes a very important direction. The environmental performance and energy efficiency of three major public buildings such as the Ministry of Industry and Minerals, the Ministry of Housing and the Central Bank of Iraq were tested using a quantitative, comparative methodology. Through the analysis of the sustainability indicators of each project, it was shown that the combination of high-efficiency glass and the optimization of building orientation reduced energy consumption by up to 20% and thus enhanced the environmental performance of the projects and reduced the reliance on industrial cooling. The study provides a unique contribution to the field, as modern technologies are combined with the traditional architecture components, which consequently offer a model that could be implemented in similar contexts at the global level. The results indicate that sustainable policies in constructing buildings in Iraq have the potential of increasing the use of local materials, which will assist communities in overcoming the environmental and economic problems in Iraq and simultaneously preserve the cultural heritage. This paper will present a new model which combines new technologies with the old ones in the sustainable construction industry in Iraq, providing a practical framework that would be flexible to similar conditions in other parts of the world.
