States that the energy initially embodied in a building could be as much as 67% of its operating energy over a 25-year period. If additional embodied energy gained over the building life is also included, the total life cycle energy could be larger than the operating energy over the same period. Notes that currently embodied energy cannot be predicted accurately due to a lack of reliable and accurate data. Describes calculation of the operational and embodied energy using the Early Design Model (EDM), an integrated and simplified energy model based on proven well-established algorithms. It is intended for use in estimating capital cost, embodied energy and operating energy requirements at the earliest stages of a design. Summarises the model in a diagram. Presents calculations for a base-case building of different building parameters including glazing and thermal insulation.
