A Combined Operational and Embodied CO2 Approach: The Limits of Conventional Insulation Materials and Case for High Performance Vacuum Technology
The imperative to reduce the carbon footprint of buildings will inevitably require higher levels of insulation.As building performance improves and operational energy reduces,the ratio of operational to embodied energy will continue to shift.Where very low U-values are required,the volume of material in conventional insulation is such that embodied carbon can begin to outweigh operational carbon savings during the projected lifetime of buildings,causing a net CO2 disbenefit.Detailed studies carried out at Oxford Brookes University based on aggregated operational and embodied CO2 analyses suggest significant benefits for vacuum insulation in relation to a broad range of building types and design scenarios in comparison with mainstream comparator insulation materials including PUR and mineral wool,specially in relation to applications with shorter design lives where the embodied CO2 investment has to be recovered relatively quickly.
