Document Summary

We need to consider different materials for different energy needs. This would affect the nature of operation carried out within the structures built. Hence, the implications of such materials need to be considered for the life cycle analysis of the building. Note: operational energy - could take from 40% - 80% of the life cycle carbon. Downstream impacts - impacts of materials at the end of their life phase. This includes: ie cradle to grave embodied energy. Reusing the building itself - changing its function. Factors to consider when assessing the end of life impacts: End of life energy use and carbon footprint. Provision of amenities and local economic activities. Consider this flowchart, presenting the criteria to which is construction projects are assessed accordingly to: It is more so the most ideal solution (dominant) given the nature of the project. Imagine the multitude of solutions being on a graph, measured according to investment return vs energy savings.
