Structure
Embodied Energy
Existing Frame
Cast concrete= 1.3MJ/kg
6000 tonnes= 7,800,000 MJ
7,800,000 MJ= 2,166 Mwh
Existing + Replacement Frame= say 4,300 Mwh
Estimated heating requirement for new building: 68 Mwh per annum
Energy saved by retaining existing frame would heat the building for 63 years
