Embodied energy research in Irish buildings
Embodied energy represents all the energy expended in constructing a building including materials’ extraction, transport, fabrication, construction and may deal with maintenance and eventual disposal. It is often overlooked during the design process despite accounting for between 10 and 20 times annual operational energy use, depending on the ultimate use of the structure. Better design standards are reducing operational energy requirements so that embodied energy is now becoming a key design issue.
Currently there is little information available to designers on the embodied energies of buildings. The objective of this project was to develop a novel embodied energy database and an innovative decision process which will enable building designers to evaluate the embodied energies of their designs.
