We don’t guess the structural performance of individual buildings so why do we guess the human performance of entire cities?

The structural steelwork of a large and complex building would not be designed without running engineering calculations. Even the smallest of buildings is subject to objective structural analysis. No client and professional team would rely on guesswork, no matter how famous or experienced the architect or engineer.

So why do we leave the human performance of places to the whim of architects who run no calculations and rely only on their instinct and ego? Why is the science of human behaviour so poorly developed? Why is chronic failure still tolerated?

In the early sixteenth century, William Harvey challenged the medical profession to take a more objective, more observation-driven approach to the understanding of the circulation of blood. At the time, medical thinking was largely based on the beliefs of Galen of Pergamon, who had set these out in the second century. Harvey challenged a medical mindset that hadn’t changed in one and a half millennia. And he encouraged his peers to embrace advances in science that allowed new forms of investigation.

We can see a similar state of affairs in the prevalence of, and institutional inertia around, twentieth century planning. Based on belief, not observation-based science, a doctrinal approach to urban planning and design pervades the professions. This is the case, whether the specific approach is Modernism, the Garden City movement or (and especially) Landscape Urbanism. Each is to some degree unscientific.

These approaches propose different kinds of urban outcomes but what unites them is a belief that the future should look fundamentally different to the form of continuously connected, dense and mixed-use urbanism found in cities for as long as there have been cities – the kind of urbanism that architects and town planners visit on their holidays.

The kind of urbanism – and here’s the irony – that Galen would have recognised. If only architecture and town planning were stuck in a fifteen hundred-year-old mindset. We would still have vehicles on the road but we wouldn’t have vehicle dominance. We wouldn’t have land use zoning that generates long-distance commuting, traffic congestion and negative health impacts. We wouldn’t be encroaching on the rural landscape with semi-detached, density-fearing dwellings.

Fundamental change in our professions is needed and science has an important part to play. In the spirit of Harvey’s observation-based approach, we need to embrace the new capabilities offered by sensing, analytics and modelling. We need to understand how cities truly work before we then form ideas about how to change them. We must move beyond the beliefs of twentieth century practice. The evidence is there to demonstrate that practice based on belief hasn’t delivered great places with the consistency required either by the investors in them or the users of them.

We can learn from Harvey, even if our end goal is the urbanism of Galen.

Space Syntax in China

How has Space Syntax been applied in China and are the findings different to those outside China? 

Space Syntax is not a prescriptive planning and design methodology. Instead it is a culturally responsive planning methodology. It begins by analysing the spatial layout of urban and rural areas and studying patterns of human behaviour, land use and land value. It then shows how spatial layouts influence these patterns. And it allows planners and designers to predict the outcomes of their proposals with greater accuracy than they could before. But it doesn’t prescribe a particular solution. Instead it responds to local cultural differences.

For this reason I am keen that Space Syntax is used by Chinese people to study and to plan Chinese cities, towns and villages. Only Chinese people fully understand Chinese life. We can train Chinese practitioners how to use Space Syntax tools, but how the findings of the research are interpreted is a different problem. It is a problem best answered by Chinese planners and designers.

Sustainability & resilience – a SMART approach

1. Aspects of sustainability/resilience: SMART outcomes
Social – improvements in formation & retention of social connections

Environmental – increases in renewable energy production and reductions in energy demand

Economic – increases in land value creation

Health – improvements in public health outcomes

Education – improvements in achievements/qualifications

Safety – reductions in offending & reoffending.

Environmental
Urban carbon footprint is made up of:
1. Building carbon.
2. Transport carbon.

Urban carbon reduction can be achieved by:
1. Building carbon reduction – intelligent building services: heating/cooling, lighting.
2. Transport carbon reduction – walking, cycling, public transport & less private vehicle use.

2. Process specification: SMART inputs
1. Integrated Urban Modelling of existing building performance and transport performance.
2. Predictive Urban Modelling of expected development impacts.

3. Asset requirements for SMART approach
1. Pervasive data sensing
2. Data mapping – centrally coordinated & then distributed eg open platform distribution
3. Data analysis – undertaken by city, academia & industry then shared
4. Planning & design response – use of data to create development proposals
5. Development proposal testing – using the Integrated Urban Model.

Sustainable cities of the future – sketch

Notes for keynote at UK Green Building Council Annual City Summit, Birmingham.

1. Spatial planning & human behaviour implications of sustainability – reduction of transport carbon through shift towards walking, cycling & public transport

2. A massive shift needed in transport + land use planning, urban + landscape design, architecture. Professional inertia. Turning the supertanker.

3. A massive opportunity. Reason to turn.

4. Lessons from the past eg Pompeii, Brindley Place.

5. Examples from the present eg Darwin, London SkyCycle, Birmingham Charette.

6. UK government: Smart & Future cities agenda is a sustainability agenda.

7. Social inequalities dimension of sustainability.

8. Need to act at all scales simultaneously ie there’s work for all of us to do.

9. Challenge for modelling.

10. Challenge for research.

11. Challenge for practice: design, development & real estate investment.

12. Already being acted on. The supertanker is turning.

Integrated Urban Planning – balancing the multiple flows of the city

Notes for the UK-China Sustainable Urbanisation Conference in Chengdu, China on 24th September 2015

  

My job as an architect and urban planner is to design new towns and cities – as well as new parts of existing urban settlements. This means designing the multiple systems that make up a city. We often think about towns and cities in terms of their physical stuff: their buildings. Perhaps also in terms of their roads and rails. But for me the success of any city can be seen and measured in terms of its flows, the flows of:

  • energy
  • water
  • data

and, most important of all, the flows of:

  • people: in cars, on public transport, on bicycles and on foot.

Each of these flows is impacted by urban development: how much of which land uses are placed where, and how they are then connected to each other. Flows impact on other flows.

Sometimes these impacts are positive, sometimes negative. They have enormous social and economic implications.

Urban planning is as much about designing flows as it is designing buildings.

We live in an age of unprecedented computing power – this gives us the ability to better predict the nature of these impacts.

This is especially important to avoid the unwanted effects of urban development: congestion, air pollution, social isolation and unsustainable stresses on natural resources.

And computing can help create the positive impacts that are needed to support the essential purpose of cities: to be:

  • machines for human interaction
  • crucibles of invention
  • factories for cultural creation.

The last decade has seen the emergence of Integrated Urban Modelling. My company, Space Syntax, is a leader in the field: one of the UK companies referred to by the Chancellor as contributing to China’s growth and development. Working, for example, with the China Academy of Urban Planning and Design across China in Suzhou and Beijing.

Integrated Urban Models link the data generated by the multiple flows and reveal the interactions that help architects and urban planners create sustainable plans. Space Syntax has identified the essential role of spatial layout as the principal influence on urban performance. Spatial analytics are at the heart of our approach to Integrated Urban Modelling and we have made our discovery open source and openly available so that others can benefit too.

The Space Syntax Online Training Platform is a freely available, web-based resource through which urban practitioners, policymakers and local residents can equip themselves with information and skills to create more sustainable urban futures.

I’m pleased to announce that this platform is currently being translated into Chinese so that the Space Syntax’s discoveries and experiences can be more readily disseminated here in China.

Integration, balance, glue, pivot: space
In many ways, urban planning is the integration and balancing of multiple flows. Integration needs glue and balance needs a pivot. Spatial layout provides both.

 

The future of Faversham Creek

Address to the Faversham Creek Trust event on board SB Repertor – speaking notes

Tim Stonor
2nd September 2015

Good evening. It is an honour to have been asked to speak this evening and I’m grateful to Lady Sondes, Sir David Melville and Chris Wright for their invitation. As I prepared for this evening I wondered if I had ever given a talk on the water. I thought I hadn’t and then I remembered I once spoke at a conference on board a cruise ship between Genoa and Marseille. I’m pleased to say I’d trade the crystal waters of the Côte D’Azur for the muds of the Côte de North Kent any day. 

We are lucky to be here and lucky to be part of Faversham. Simon Foster mentioned the work I’m involved in that’s looking at the UK 50 years from now. This may seem like a long time but it’s a drop in the ocean/Creek for Faversham. Here we have at least 9,000 years of continuous human habitation. There aren’t many other places in the UK that can claim this. In fact we don’t yet know of any that can.

And why did people first come here and then stick around for so long? It’s the Creek. First for the hunting: its game, its fish and its fowl. Then for its waterborne trade. We are one tide from London, where merchants could poise offshore, like greyhounds in the trap, waiting for fire signals from London to tell them their stock prices were high enough to catch the next tide in.

This place is important. This water is important. Many of us feel this viscerally. Others still need persuading. How can we do that?

I have seven thoughts. Continue reading The future of Faversham Creek

Designing Resilient Cities – creating a future Avalon

Designing Resilient Cities – notes from Day 1
A note from the Vice-Mayor for Infrastructure to the Mayor

The Public

Avalon faces the risk of functional failure. The only way forward is to change.

Our infrastructure is inefficient. It needs to become efficient. This is not just a question of maintenance. There won’t be enough money to run the transport network, supply water, remove waste, provide broadband. Unless the city either shrinks to a size its current economic structures can afford; or grows to create a larger tax base – so long as the city can retain control over how that tax is spent.

The view of the infrastructure team is that Avalon should grow. But not off the back of its existing industries. These are running out of steam. The industrial infrastructure of the city needs to expand and to reinvigorate. Creative industries will be central to this.

A new population will come to Avalon. A younger population, joining the older, wiser and more experienced population that built the city’s wealth in the 20th century. Joining young people who, having grown up in Avalon have chosen to stay there rather than take the increasingly well-trodden path elsewhere. The city has seen too much of this. Its infrastructure of talent must be rebuilt.

And these people will need somewhere to live. Houses that are affordable. We need to build.

But this does not mean ever further sprawl into our precious countryside – which is too beautiful and too productive to become a building site. No, it means building on our existing urban footprint. We need to find space within the city, not outside. Some of our redundant industrial sites will provide excellent places for new housing: close to transport infrastructure, with excellent, ready-made supplies of water and power. We need to look hard at the vast city parks that were built many years ago and have simply not worked as they were intended – they have harboured crime rather than nurtured culture.

And culture is central to what we must do. Avalon needs to recapture the spirit in which it was first built: a pioneering spirit where anything was possible. Music, art, sculpture, performance: song and dance – we were good at it when we tried. The future memories of Avalon will be built on the strength of the cultural infrastructure that we put in place in the next few years.

And to achieve all of this we need to change the way that we make decisions in the city. No more top down dictats. We need a governance infrastructure that involves everyone: participatory planning, budgeting and decision-taking. An elected mayor for a start.

Designing City Resilience is a two-day summit at the RIBA, 17-18th June 2015. Avalon is one of four imaginary cities being looked at during the event in a creative approach that breaks the mould of typical, presentation-only conference agendas. By engaging in a rapid prototyping exercise, delegates immediately test the ideas they have heard in the keynote presentations and on-stage discussions. They also bring to the event their own international experiences.

The result is a two-way, creative conversation that produces a richer outcome: a set of designs for the transformation of the physical, spatial, environmental, industrial, educational, healthcare and governmental structures of the four cities.
