NLA Green BIM Conference
What is 'Green BIM'?
@caseyrutland
Everyone talks about data...
Material Area/ volume call off
Embodied carbon
Life cycle analysis
Responsible sourcing
Material ingredient reporting
@caseyrutland
Yes. But...
@caseyrutland
There are two key areas...
...where we can make bigger, more
meaningful differences

7 pillars of sustainability
• Social Sustainability
• Carbon Neutrality
• Water self-sufficiency
• Sustainable material selection
• Climate change adaptability
• Positive community contribution
• Sustainable in operation
@caseyrutland
Social Sustainability
Biophilia Hypothesis:
The concept that humans
have an innate attraction
to living things and
nature.
@caseyrutland
Carbon Neutrality
Shape, Orientation, Massing, Materials,
Size
Activities & Associated systems
The supply of energy.
All now based upon reliable calculable
data from BIM files
@caseyrutland
Self-Sufficient Water Use
Surface area calcs. vs. water usage
Now based upon actively updated
calculable data.
@caseyrutland
Sustainable Material Choices
Globally, the construction industry is
arguably one of the most resourceintensive and environmentally
damaging industries in the world.
The construction sector consumes 40%
of all extracted materials.
Data extracted from models.
@caseyrutland
Climate Change Adaptation
Buildings last a long time.
Using BIM we can simulate what the effects of a 2 degree temp rise
will be upon the building and its occupants.
We can simulate the implications of rising floodwater.
Ensuring robust longevity.
We can mitigate against these occurrences and the effects our
buildings have on the environment.
@caseyrutland
Sustainable in Operation
The result will be more and more
'intelligent' buildings, metering themselves
and verifying their performance against
benchmarks.
@caseyrutland
Sustainable in Operation
@caseyrutland
What does it look like in practice?
@caseyrutland
Using technology to optimise
Trust digital processes!

Controlled whole-life costs and
environmental data
Environmental performance,
maintenance and investment is
predictable. Lifecycle costs can be
analysed and understood.

Some degree of climate change appears inevitable.
@caseyrutland
Quote...
Whether it is manageable or catastrophic, will not be determined in
Washington, Geneva or Beijing, or by domestic legislation and international
treaties or by silver-bullet energy technologies.
@caseyrutland
Quote...
But mostly by how we – the architecture, planning and building community
– respond and act.
@caseyrutland
Quote...
We can choose to plan, design and build truly sustainable, liveable and
resilient built environments;
@caseyrutland
Quote...
...or we can accelerate climate change and ecological degradation, leading
to increased human suffering.
@caseyrutland
Quote...
How we plan, design, and build today will have lasting impacts for our
children, communities and planet.
@caseyrutland

It really is up to us.
@caseyrutland
