What is LCA?
Products Building (completion) Building (end of life)

Focus on: life-cycle impact data and integrity
– BRE LCA data (Ecoinvent with UK Trade Association data):-
– IMPACT generic materials– IMPACT manufacturer specific– ‘Pre-made’ IMPACT Spec library
– Uniclass categorisation
– Updatable and flexible data format
– EU 15804 EPD ready
– Automated validation rules
Focus on: Environmental Reporting
– Thirteen indicators
– BRE Ecopoint
– BS EN 15978 style life stage reporting:
– Product stage (‘to gate’)– installation– in-use and – end of life (+ above = ‘to grave’)
– Flexible study periods (0 to 80 years)
– Can report operational and embodied together

Parting thought!
How can any building claim to be sustainable without LCA & LCC consideration within in the design stage……
