Finally, and based on the necessities of measurement inside the building, several
acquisition modules, such as the one shown in Fig.
2.10
, have been physically dis-
tributed by means of an Industrial Ethernet network all around the building. More
specifically, the indoor plane of the building has been split into different zones con-
sidering several measurement cores, see Fig.
2.11
. Each one of these cores is respon-
sible for the connection of a sensor set to the Ethernet network in order to be made
available from the acquisition and monitoring centre. The communications network
architecture inside the building can be observed in Fig.
2.12
.
2.3.2 Sensors: Description and Location
The building has a wide network of sensors installed all around the building. This
network can be divided into four representative blocks, which are gathered according
to the location and the main purpose of each of the sensors.
Sensors inside the building.
As can be observed in Table
2.1
, inside the building there is a huge variety of
different kinds of sensors with a total of 161 measurements. Most of these sensors
have been installed to analyse users' comfort inside different environments of the
building. To do that, five characteristic environments of the building were selected
(two offices, two laboratories and the meeting room), and inside them a wider
network of sensors was installed, see Fig.
2.13
.
Sensors in the meteorologic-radiometric station.
The building has a meteorologic-radiometric station placed on the roof of the
building, see Fig.
2.14
. It includes a large amount of sensors which are detailed in
Table
2.2
.
Sensors in the ventilated facade.
As can be observed in Table
2.3
, the zone with the highest sensor concentration is
the ventilated facade. This zone, which has been selected to analyse the thermal
behaviour of this kind of enclosure, is located in the southern facade of the building.
The ventilated facade includes a huge set of sensors gathered at different heights
and depths. More specifically, it has temperature and thermal flow density sensors
at different planes and heights. In addition, it also contains air velocity sensors
at different heights which are placed in the wall cavity. Moreover, in the external
surface of the ventilated facade there are global and infrared radiation sensors,
and wind velocity and direction measurements. Furthermore, it also includes a
temperature sensor set distributed in the wall cavity that allows to determine if the
flow inside it is laminar or turbulent, see Fig.
2.15
. Finally, on the other side of the
wall, there is one of the offices selected as characteristic, and therefore it has an
equivalent sensors set. In this way, both the behaviour of the ventilated facade and
its effect on this office can be analysed.
