3. HOW IS A SMART CITY SHAPED?

Smart cities can only be achieved through a multi-disciplinary
approach at different levels.

· Strategic level / Master-planning: vision, strategy, planning

policies, and legislative and regulatory documents and
guidelines

· Technical specifications level
· Implementation, operation and maintenance level

Whilst smart solutions have all in common to rely on a robust ICT
network, they are applied to different core systems of a city.

Smart waste management

Smart waste management includes the recycling/treatment of
waste and waste water to compost, energy and fuel.

Aim:

It aims to monitor, target and reduce construction, excavation

and everyday waste.

Resources

Smart water systems

Smart water systems refer to the management and control of
water supply and quality via advanced analytics, sensors and
monitors.

Aim:

Smart water systems can detect problems and reduce

consumption leakages; achieve maximum efficiency via recycling;
regulate water usage according to environmental conditions; and
anticipate flooding and develop predictive models and warning
systems.

Application:
Lockheed Martin's Sunnyvale facilities, Silicon Valley, California
Watering with a smart weather controlled irrigation saved
477,000 m

of water each year; minimized overwatering,

preventing cracked foundation and asphalt resurfacing; and
reduced the annual cost.

Ijkdijk foundation, flood embankments, Netherlands
A geotextile fabric TenCate GeoDetect13 equipped with optical
fibers, instrumentation equipment, and software was deployed.
This sensor was linked via internet to databases. It provides a
42-h-prediction and enough time for large-scale evacuation.

The network has become the next utility.

Smart energy

Smart energy implies the use of an electrical grid including
smart remote meters, smart appliances (electric vehicles and
thermal-storage air conditioning), fiber optic telecom, continuous
monitoring, advanced electricity storage, renewable energy, and
energy efficiency resources.

Aim:

Smart energy aims to improve reliability, security and

efficiency; to manage the peaks; contribute to a sustainable
energy supply and reduced consumption. It also involves
consumers in the energy supply and responds to rising demand
for electricity.

Application:
Smart grids all over the UK would cost £19 billion less than
maintaining the existing network over 2012-2050, stimulating an
export in market goods and services worth up to £5 billion.

Every $10 billion spent on water/energy efficiency
in the US makes it possible to save 35.2 billion m

water, with energy reductions as well, create up to
220,000 and increase GDP by $13-$15 billion.
