Wouldn’t it be good… Getting started Better… Even better! What’s next?
WOULDN’T IT BE GOOD…3
To know the embodied carbon of our structural designs as we design
To generate a lifecycle carbon footprint including embodied and operational carbon
To be able to benchmark our designs against others
And much later: To comply with BREEAM/LEED etc
GETTING STARTED…4
Spreadsheets (2009)
Portland cement73%
GGBS0%
PFA0%
Water13%
Water reducer0%
Aggregate2%
Reinforcement12%
GETTING STARTED…5
Revit tweaking (2012)
BETTER…6
IES Environmental LCA (2014) BIM → BEM Add environmental material data to energy model Measure whole life (design) performance
BETTER…7
IES Lifecycle Costing Basic
assessment Can use
database or custom input
BETTER… BUT NOT PERFECT8
IES IMPACT Difficulty with non-thermal elements Bespoke material build-ups Outdated version with many errors
File exchange challenges REVIT to IES Convoluted model, requires
‘decluttering’ but Decluttering means much of the
material data is lost Requires architects to follow model
setup protocol
BETTER… BUT NOT PERFECT9
Benchmarking is difficult!
EVEN BETTER! (…AND BACK TO REVIT)10
Focus on materials and add in use data later (2016) BEM → BIM
EVEN BETTER! (…AND BACK TO REVIT)11
Still requires lots of data input by hand
