Thermal-camera walk: see where houses lose heat, Roubaix
Roubaix is a red-brick textile town next to Lille, and on a cold December evening its terraced houses show exactly where the heat escapes. On this guided walk an adviser from Urbanis carries a thermal camera along the streets, explains insulation faults on the screen and talks through concrete fixes. A curious, practical hour in a small group. Free, but sign up with the city's housing service (03 20 66 48 70 or pha@ville-roubaix.fr). «Balade thermique à Roubaix» Starts 17:30, ends about 19:00.
