Overview 1. The Context of BIM 2. Getting into BIM 3. BIM & Passivhaus
1. The Context of BIM
BIM isn’t new!
Why now? 1. Software & Hardware capabilities
3d Modeling Structured Information Digital Collaboration
Why now? 2. Digital / Social Media ‘Tsunami’
Digital everything Social everything … will the construction industry catch up?
Why UK Gov + BIM?
EU Directive Energy Performance of Buildings Buildings consume 40% of energy in EU By 2018 All new public buildings “Nearly Zero-Energy” By 2020 All new buildings “Nearly Zero-Energy”
UK Gov Strategy
Mandated BIM
What is UK Gov BIM? “Building Information Modeling (BIM) is the process of generating and managing information about a built asset over its whole life.” Cabinet Office 2012
UK Gov Purpose 20% reduction in capital costs 20% reduction in CO2 emissions + reliable outcomes + predictable building (asset) performance
UK Gov BIM + GSL
BIM standards
BIM Protocols
2. Getting into BIM
Observing Pre-BIM Duplicate working
Designing in 3d, documenting in 2d
CAD standards not always enforced
Proposing BIM Quick “proving exercise”
Demonstration of key benefits
Overcoming doubts & resistance to change
BIM Pilot Project Rules
Small / Medium single storey Short duration Bland, not too creative Plan for pulling back to CAD
BIM Pilot Project Rules
Benefits Carefully manages risk, minimises potential losses
Facilitate a gradual transition / learning
Allows for easy comparison between projects
Risks No benefits of BIM gained
No memorable experiences
No mindset-shift
Following the Rules: “BIM is a RISK to be managed”
OR… No Rules? Large project, multi-storey Long duration Highly creative, challenging design Commit to BIM, no plan to pull back to CAD
Start! With a project that matters to your business
Benefits Maximises all available benefits of BIM
Longer duration allows for learning & mistakes
Exciting, interesting, engaging… the BIM mindset sticks
Risks Much more at stake that could go wrong
High level of training & support needed
Takes longer to see the results, harder to compare
No Rules “BIM is an OPPORTUNITY to be realised”
BIM vs CAD

Our Pilot Project
The Willows £17m / 6500sqm Lifelong learning campus Multiple clients Complex geometry 6 Phases, 10 Mineshafts
Ensuring Success Training / Support
Project based bespoke training
At desk training
In-house expert (guess who?!)
Ensure Success The Team
Tasks to suit abilities (not roles)
Focus on LOD for outputs & outcomes
Involve whole team in the real-world project
Results Stage D output in 4 weeks, reduced Stage E-F team 500+ drawing sheets,1355 unique views directly from the digital model Massive productivity gain Site RFI turn around in hours (not days!)
Bonus Results Unexpected use of the model Staff exceeding expectations Spread of BIM skills
5 Stages of BIM
1. Initial Excitement “Wow, Look what I can do with this thing!”
5 Stages of BIM
2. First Bump “Why won’t it do what I want? …It was easy in CAD!”
5 Stages of BIM 3. Creamy Middle
“Things are going smoothly now”
5 Stages of BIM
4. WTF!? “Component Creation eats you up and spits you out”
5 Stages of BIM
5. Enlightenment “Things really click. You understand why things happen in the model, how to control them and how to avoid problems”
State of Mind vs Skill
State of Mind vs Skill
State of Mind vs Skill
Beyond the first project Internal uptake External demand The wider design team / Level 2 BIM
Bidding
LOD
Designing
Communicating
Almost Level 2
3. BIM & Passivhaus
Passivhaus Standard “…the world’s leading standard in energy efficient design” Rigorous performance standard Quality assurance Optimal comfort (ISO 7730) Minimal energy Climate specific – works anywhere
PHPP: BIM or BEM? “simplified models, precise data” Accurate Open Parametric Instant
Data 4 QA Passivhaus can be seen as a quality assurance standard that ensure that the right information is used at the right point in the process to deliver reliable robust energy performance & comfort.
BIM + Passivhaus Process + Information + Model and test
Not box ticking Not sexy graphics Not on site
BIM 4 Passivhaus Simple + Useful + Productive 1. Visual interrogation 2. Accurate Live Numerical Data
Visual Interrogation Design coordination / integration Thermal Continuity Heat Loss Envelope

What does this deliver? 2 x 65kW Boilers for a 2200m2 School 25kW peak heat demand = 5x oversized! 90% reduction in gas consumption
Breathe easy!
“We feel that our children are more alert and attentive in lessons due to the amount of daylight in classrooms and the fresh air throughout the school ... learning has been enhanced” Sara Morris, Head Teacher
