 Strengthen the sensing system construction for green belt of forests, wetlands and other natural
resources, and timely access green resources situation combined with geospatial databases.
 Use sensor technology, communications technology and other means to improve the monitoring,
control and management on the thermal energy and building temperature systems.

Through the improvement of an overall smart system, water, electricity, natural gas, coal, oil and
other resources could be reasonably allocated and utilized. Sensors installed in strategic locations,
territories and cities are improving the monitoring of environmental variables and disposing higher
information for decision‐making.

It is necessary to incorporate clean and responsible management of waste, thus the amount of
waste produced by citizens is one of the future challenges within the concept of clean and
sustainable cities.
For example, in the Dutch city of Groningen, a personal card is required before depositing wastes in
a container. This personal card would record every time the user opening the lid and therefore
assemble behavioural data of the user with the hope of encouraging responsible waste
42
management .
Another of these smart elements is the fill control, whereby when the container is full emits a signal
that alerts the garbage collection service. In this way, routes and schedules are optimized, the time
spent on garbage collection is improved. This process also saves energy and reduces CO2 emissions
by better organizing the transport and avoid the unwanted waste in the street by overfilling
containers. These advantages are made possible by the incorporation of chips in containers, which
generate appropriate signals by microwaves, providing all necessary information, such as
temperature. If the container temperature passes from some determined degrees, the chip shall
deliver signals to firefighters to avoid fire. This not only minimizes the risk, but also extends its useful
live, with consequent cost savings.

3.7 Smart building, digital home

The city life does not end in public spaces like streets, squares, parks, etc. It also includes the life of
the population in their own homes and in public and private buildings; that's what one calls a
digital/smart home/building.

A smart building is the integration of building, technology, and energy systems. These systems may
include building automation, life safety, telecommunications, user systems and facility management
systems. Smart buildings recognize and reflect the technological advancements and convergence of
building systems, the common elements of the systems and the additional functionality that
integrated systems provide. Smart buildings provide actionable information about a building or
43
space within a building to allow the building owner or occupant to manage the building or space .
