I am wondering if there is any literature review or any other types of information about the consumption of different materials, e.g. cement, concrete, and steel in the construction of different building types, i.e. residential and non-residential, especially in Australia. I also would like to know if there is any literature review about the embodied energy of the different materials, and the impacts of the consumption of the different materials on energy consumption and Co2 and GHG emission the building operation phases? As you know, building materials have somehow lots of things to do with building efficiency during the operation phases by affecting cooling, heating, ventilation, and even lightning, hence have lots of things to do with Co2 and GHG emission, and have an essential role to be considered in any mitigation action plans.
