## 2 Methods
### Questionnaires  
The approach of the questionnaires followed a four-phase methodology (Figure 6). The first phase involves designing a survey to gather necessary data. After conducting our study, we identified an interactive kiosk as the most suitable Smart Street Furniture to display information gathered by different humidity and temperature sensors throughout the city. In the second phase, we implemented a citizen data collection system with a web application focusing on Human-Computer Interaction and User Experience to encourage massive citizen participation. This web application allows citizens and visitors to access the survey designed for this study. The third phase involves placing the interactive kiosk in the town hall, a central location for Balaguer. The survey aims to collect responses from citizens and visitors to analyze the information gathered. Finally, in the fourth phase, we analyze all the collected data, discuss it, and draw conclusions. In the fourth phase, the government analyzes the data collected and adjusts their actions to align with the citizens' needs. City councils seek citizen feedback on aspects of city life for more attractive, useful, and closer projects. In this way, they help to enhance citizens' trust in their government institutions. Figure 6 provides a graphical illustration of the entire process. Figure 5: Further PV installations planned. Figure 6: Four-phase methodology diagram. As part of the infrastructure to complete questionnaires, an interactive kiosk named Totem Outdoor DELUX, ins-digital (Madrid, Spain), with a 65\" 2500 cd screen is provided (Figure 7). It runs on an Intel I3 CPU and Windows 10 Pro 64-bit operating system. This kiosk displays three types of data: information about the sensors installed in various Balaguer buildings, details required to complete the questionnaires, and static information about Balaguer city and town hall. All this information is displayed on a web page. For this purpose, the interactive totem connects to two servers. The first is a web server with HTML5, CSS3 and PHP 8.1 code, which manages the data obtained from citizens in a relational database. The second is a Grafana server (V9.0.2), which collects data from the different sensors in relevant buildings in Balaguer and generates pre-designed graphics. The Grafana server then sends this information to the digital totem for display in real-time. The questionnaires given to citizens included questions about their general information (age and gender), their life in Balaguer (origin, length of stay, neighborhood of residence, and preferred neighborhood), their opinions about the city, their perception of the atmospheric temperature, and their emotions generated by the weather. The questionnaires were designed using [PERSON]'s heuristic rules [PERSON] (1975). They were displayed in the central left part of the device screen to make it easier for citizens to interact with the system. The questionnaires were presented as a challenge under the question \"How Balaguerian are you?\" to motivate citizens to participate. At the end of the participation, the system displayed statistics that compared the individual answers of each citizen with the accumulated answers of all the participating citizens. The objective of collecting and analyzing the questionnaire data was to interpret social data and their relationship with the following SDGs:  
* SDG3: Good health and well-being: citizens should be aware of the temperature in public buildings, as it serves as an example of the temperature that should be maintained in private homes. * SDG5: Gender Equality: the study results have been analyzed from the perspective of the participants' gender. * SDG9: Industry, innovation, and infrastructure: the totem pole installed on the city hall's door is an innovative public infrastructure for the city. Figure 7: Balaguer interactive kiosk displaying the system implemented. * SDG10: Reduce inequalities: to reduce inequality, citizens can provide input on which neighborhoods need revitalization.
