3. A Green City from a Green Field
How do I plan and build a large city from a green field ?
I need so much information !!!!
Everything is connected to everything !!!!

4. Thinking of a City as a Dynamic System
“When do we begin thinking of cities as integrated systems –
dynamic systems – the way we think about aircraft or spacecraft?”.
“The Construction Sector is known for low productivity, poor
integration, and a terrible record of “fit and interference” no other
sector would tolerate. There is little or no life cycle management!”
How do we escape this?

5. Thinking of a City as a Dynamic System
“How can I better integrate the city’s systems for the
movement and management of goods, people, water, air,
electricity ?”
Cities face serious challenges ? Water? Heat Islands ? Access to
food? Air Quality ? Crowding? Not making the climate worse?
What tools are there to help us cope?

6. There are so many solutions!
• Green roofs – walls
• Solar roofs - walls
• Suitable materials
• Building form – size/orientation
• Passive ventilation
• Better use of green spaces Lots of Strategies!
• Increase ground permeability
• Reduce use of air conditioning/heating
• Increase/decrease density How do I choose?

8. Intelligent City Models can help!
• What is a city model?
• City Models are a foundation for planning,
construction and operations.
• A concrete example – Permit Infringement.
• Other real world problems.

10. What is an Intelligent City Model?
• Comprehensive, multi-level of detail – 3D –
model of all city structures – suitable for
simulation & analysis and decision support.
• Support Multiple Applications in
– Planning
– Construction
– Operations
– Communications
• Fundamental information resource

City developers submit drawings for a
project, but then build something that
deviates from the submitted drawings.

15. City Model Application - Green City from a Green Field
How do I plan and build a large city from a green field ?
1. Develop a design process
2. Integrate the design process into the fabric of the city.
3. Integrate permit/zoning/design together from the start.
4. Build/Integrate intelligent city model from the start.

18. Security Requirements
• Security applications require access to the
entire city model(s) + additional detail.
• Additional detail is confidential.
• Security applications require simulation
functionality (e.g.):
– Inter-visibility.
– Electromagnetic field mapping.
– Radar field mapping
– Internal/external routing analysis

• Urban challenges are urgent!
• Urban challenges are complex & interconnected!
• Intelligent city models can help!!
• Models must be sustainable – current – accurate!
• Models must be shareable – usable by diverse stakeholders
• Open standards (e.g. GML, CityGML, ifc, …) and
information infrastructure technology can realize
model potential !!
