Retrofitted apartments in Lighthouse City Vitoria-Gasteiz are ready for monitoring

09 Jul 2019

The deployment of necessary ICT Infrastructure is taking up pace. In connection with the building retrofitting process in Coronacion, the Vitoria-Gasteiz demo area, the deployment of the necessary ICT infrastructure for the monitoring of energy consumption and comfort conditions of the households is speeding up.

After finishing the installation in the first retrofitted buildings, the so-called “early adopter communities”, the activities continue at a higher rate in the next communities.  More than 50 dwellings are about to start with their building retrofitting works. That is why various information meetings have taken place within the neighbourhood to explain the monitoring equipment.

What kind of sensors are going to be installed? What kind of data will be collected? What about my privacy?  These information events were organized to help people to understand the monitoring process and to resolve all doubts. Citizens were not only informed on technical requirements for the installation but also on confidentiality issues.

The sensors that are going to be installed include electricity consumption, temperature and humidity. CO2 sensors will be also installed in some of the households to control indoor air quality.

Special permit forms were requested in order to place the sensor inside the smart meter boxes. The following images show a smart meter box before and after installation.


The TV coaxial cable available in each building is used to establish a building network used by comfort sensing devices to send their measurements to a 4G router that sends the harvested data to the city platform. The following images show the installation of one of the dwellings. On the left, the TV coaxial cable connection; on the right, the temperature and humidity sensor with the display and the data communication system.

Monitoring first promising results:

Regarding the results of this sensors deployment, the first group of sensors was set in Eulogio Serdán nº4 & nº8 as a test group. Despite the fact that rehabilitation works finished in February, there are not many data collected, yet, but a quick analysis reveals some first results that seem to be very promising: it has been noticed that gas consumption has decrease almost 50%. Even though the works finished in February, the insulation was already placed in the October-December period, it can be stated that the new envelope has been “working” since early December. Due to this data, it can be stated that the impact of the insulation on the gas consumption could be recognized immediately.
