INTEGRATING SUSTAINABILITY DATA IN BIM

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IES IMPACT Difficulty with non-thermal elements Bespoke material build-ups Outdated version with many errors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

EVEN BETTER! (…AND BACK TO REVIT)12

Still requires lots of data input by hand

EVEN BETTER! (…AND BACK TO REVIT)13

Still requires lots of data input by hand
