= in which scenario does the community behavior bring
more advantages?
» where are connected IBs more powerful?
Different scenarios and building performances have been
analyzed and compared, with the aim to understand which of
them is more suitable to prove and/or support the research
hypotheses. If every Intelligent Building is already capable to
optimize the internal performance, why should it be connected
to other buildings? Which effects are expected by this
operation? Which are the situations in which buildings can take
advantage of the community structure?
The following topics have been analyzed:
Global scenarios
» lighting
= heating/energy
= energy consumption
= weather protection
" security
Lighting and visual comfort will be the application scenario for
our research.
23 Technology
According to the research hypothesis and target, a connection
between buildings, sensors, simulation, tools for decision
support, actuators and building components has to be realized
through a central control unit that collects input data deriving
from external sensors and outputs consequent recommendations
according to on-line or off-line simulations.
Tools for the realization of connections can be very many: GIS,
CAD, Simulation Programs, Building Automation, Facility
Management, SAP, Neural Networks, 3D Visualization. (Fig. 3)

Figure 3. Tools for connection of cells in the building organism
According to the basic assumptions, each IB (or cell in the
building organism) makes local experiences and adapts itself to
the local environmental changes. Experience and adaptation
parameters will be sent to the organism central control, to be
interpreted according to the local natural and built environment
for each building. According to topological relationships of
International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B3. Istanbul 2004
each IB and the environment, the GIS-based central control will
be planned and developed to translate the experience of the first
building into suitable recommendations to each of the other
buildings. Locally, in every building the user will decide
whether accept a default standard solution or to choose
interactively in the palette of provided recommendations. (Fig.

Figure 4. Our GIS-based central control as a “translator” of
single experiences into targeted recommendations
The two main GIS capabilities are the key tools for success in
communication of experiences and adaptability of buildings:
» topology/geographical handling of data (built and
natural environment around each building is taken
into account in the translation of recommendations);
= decision support: the system presents a list of
recommendations to the user, who can autonomously
decide how to behave.
The major GIS functionalities are the only ones that can play
the basic, fundamental role of Information System and can
support integration.
The GIS functionalities role will be:
- data management;
- control of communication of sensors and between sensors and
control information;
- realize what is happening in one building and find out the
impact on the other buildings, and therefore:
- perform analysis on data and produce building control data
(recommendations) on basis of what other tools provide;
