It is becoming increasingly apparent that the impacts of buildings extend far beyond operational energy and carbon. As the thermal standards of buildings improve, attention will shift toward wider life cycle impacts including material production, transport, construction waste, on-site activities, material replacement, maintenance and finally the end of life of the building. These life cycle stages have a considerable impact, yet they are often neglected. This workshop will equip participants with the skills necessary to calculate the life cycle impacts of buildings (residential and commercial) through a series of hands-on exercises. These skills can also be used to compare different design options while reducing the embodied energy and carbon of a real building. The workshop will conclude with best practice case studies of projects that have reduced their embodied and lifecycle impacts without increasing cost. Content of this workshop is suitable for basic and intermediate level participants.
