Sensing the city of the future

Absolute World TowersSay “architecture in the future,” and you’re likely to think of buildings with a radical design, like the Absolute World Towers near Toronto, which twist some 200 degrees from base to top. But while architecture in the future might still be a feast for the eyes, other senses and feelings are likely to get more satisfaction as well.

Over the last 100 years, architecture has been a conversation about style,” says David van der Leer, executive director of the Van Alen Institute, a New York-based nonprofit architectural organization dedicated to the belief that design can transform cities, landscapes and regions to improve people’s lives. “What still largely is lacking in the conversation is how do we actually respond to the spaces we inhabit. If we know how the mind or body responds to the city, we may look at completely different ways of designing buildings.”

Recently, the institute undertook a project to understand people’s reactions to the city around them. The researchers walked around New York with residents of that city to find out how one, for instance, responds to a busy intersection. Often the subjects, who were wearing brain monitors, would respond that everything was fine, but “their brain activity says something else,” Mr. van der Leer explains. “If we don’t respond well to structures, why do we build them?”

The growing field of environmental psychology attempts to better understand the link between people and their surroundings. But scientists and architects still tend to work separately. “Research is happening, but there’s a disconnect between people being trained as designers and this type of knowledge,” Mr. van der Leer says.

Eventually, such research may lead to a different type of design, the way computer-aided design led to a surge in curvy buildings, and in the 1800s cast-iron structures allowed buildings to go higher without the need for thick walls.

In the 1960s we were so excited about the car in cities,” he says. “We put big parking lots and highways in the center of cities. We believed in speed. Sixty years later many still love the speed of the car but think about these particular design interventions in the city very differently.”

Today, the focus is on resilience and sustainability. “We need to know what is working and what isn’t, so buildings and cities become more sustainable to run,” he says.

Understanding how people react to architecture requires data, and sensors offer a new way to collect that data.

Masdar is a sensor-thick city being built from scratch near Abu Dhabi in the United Arab Emirates that is expected to be home to 40,000 people. Movement sensors, rather than switches and taps, will control lights and water. Transportation will include a driverless, point-to-point personal rapid transit system. Masdar will be the “world’s largest cluster of high-performance buildings that, together create a real-time laboratory to monitory and study how cities use, conserve and share resources,” the city’s Web site says.

Christchurch, New Zealand, also intends to carpet its infrastructure with sensors. The city’s downtown was almost completely destroyed by a series of earthquakes in 2011.

What are the issues facing Christchurch as it’s being rebuilt and what kind of data would be needed to help make decisions?” asks Roger Dennis, who founded Sensing City, a project to collect data to drive Christchurch’s rebuilding. “We’re creating the first place in the world where you can measure lots of variables in real time,” from air and water quality at a granular level to footfalls and traffic on major streets.

I’m interested in things like the air quality outside my son’s school between 3 p.m. and 5 p.m.,” he says. “Data on a citywide level averaged over a year doesn’t tell me anything.”

Christchurch is aiming to become not just a smart city but a “sensing city with smart citizens,” he says.

Mr. Dennis is counting on Christchurch’s 340,000 citizens to use ever-cheaper technology and ever-smarter phones to deliver crowdsourced data. He says although top-of-the-line sensors deployed by governmental agencies will give more accurate readings, they are too expensive to put everywhere. The richness of crowdsourced data can make up for lower accuracy. “Information from lots of people can give you better accuracy than from one government agency,” he says.

An early project is water quality testing, using paper-based kits that test levels of potassium hydride, nitrite, hydrogen and hardness in the rivers. Called “the Little Water Sensor,” the kits were designed by the Massachusetts Institute of Technology’s Little Devices program and cost only a couple of dollars apiece. Residents can use them to test water in the city’s rivers and upload the data via smart phone to MIT, where it will be interpreted, geotagged and added to the crowdsourced database.

Another project involves using sensors on inhalers of patients with COPD, or chronic obstructive pulmonary disease. When someone takes a puff on the inhaler it will send information and a geotag to the cloud. The data can be compared with air-quality data, which could help doctors understand which conditions provoke patients’ symptoms.

Sharing Energy in the City: 2030

By Aurelien

With the development of decentralized electricity and energy production, the sharing of energy between citizens, industries and public institutions will certainly reshape our relationship to energy in our everyday life. With this in mind, French electric utility company EDF decided to launch the prospective challenge “Sharing Energy in the City, 2030” in order to stimulate interdisciplinary innovations and to foster international opportunities dealing with this major and inspiring issue which affects us all.

Watch the video below to learn more about this initiative:

If you are keen on the urbanization, energy and sustainability topics and working as a researcher or postgraduate student from a lab/school/university/incubator/cluster (or if you know someone in those fields), then this challenge is a fantastic opportunity to bring your project to life!  :D

6000€ in Prizes will be awarded to the most innovative and collaborative projects, but more importantly, a 6-month work placement, connection with key stakeholders and funding for your project from EDF are the real rewards of this Challenge.

All details regarding the expectations can be found on the dedicated website and Community “Sharing Energy in the City, 2030“. You can also tweet questions to @Challenge_2030. Don’t wait too long, the deadline for applications is March 31, 2014!

3D City Management: Traffic!

Hello dear 3D Perspectives readers and bloggers,

This is a follow up on 3D City Management as promised in my previous post. In the last episode I explained how noise could be simulated and visualized in a 3D scene.

Today, I’d like to talk about another aspect of our everyday urban life. Traffic!

Most of us spend a lot of time in traffic and wonder how car flow could be optimized and made more fluid, saving us precious time. The old-fashioned way to create roads and traffic infrastructure is by building roads that connect point A to point B.

But if we want to create a city with a sustainable design and framework, we need to consider different elements before finalizing decisions: noise, air pollution, carbon footprint, energy consumption, etc. As a result, decisions about road infrastructure become more complex and need to be supported by simulation software that can optimize the combination of all these factors.

We are currently working with talented people at a French public research institute focused on traffic simulation: LICIT (ENTPE/INRETS) and LTE (INRETS) who have developed a dynamic traffic simulation application (SYMUBRUIT). The value of their approach is to be able to open their model to dynamic attributes like, speed, size of the streets and random events.

The outcome of these studies gives a much better understanding on the decisions that need to be made to optimize traffic and environmental impact.

For example the result of a recent study demonstrated that a roundabout reduced noise by 60 percent, fuel consumption by 80 percent, and the fluidity of the traffic was improved by 30 percent.

Now I’m not sure all of us believe that roundabouts are the best solutions everywhere!

We all need to be convinced. A realistic 3D simulation would help to better understand these studies. That is why, in cooperation with the CSTB (MoDev), the SYMABRUIT results can be rendered in a 3D scene with modifiable simulation attributes. It becomes much easier to understand.

See for yourself in the video below. Here you can see the impact of a traffic light being moved combined with a modification of the average number of cars per hour.

Once again we see that building and city management require powerful simulation capabilities combined with a powerful way to communicate the results to citizens. This is where the potential of 3D can be fully exploited. It’s also a direction we are exploring at Dassault Systèmes.

This post concludes this first series on 3D City Management. I hope you enjoyed it! Stay tuned, I’ll announce the next series soon.

See you soon!
