The demonstrator is an urban scenario built and equipped from late 2014 to early 2015 in order to start making scientific experiments before completion of the climate chamber. The demonstrator is the first 250m² communicating mini-town equipped with 80 sensors. It was commissioned in January 2015. This scenario focuses on instrumented housing and smart roads. It is located on the site of the Bienvenüe building, and undergoes real weather conditions.

Since its inauguration in 2015, the demonstrator has hosted fifteen experiments, covering a wide spectrum of topics related to sensitive cities:

• Indoor air quality
• Outdoor air quality
• Building energy performance
• Measurement and representation of temperature fields
• Data collection architecture
• Urban monitoring using RFID tags
• Wireless sensor networks
• Photovoltaic roads
• Water quality in networks
• Interactions between cyclists and pedestrians
• Detection of buried objects
• Instrumentation of concrete using embedded nanosensors
