FROID·5°C
Which Paris buildings are actually cold. Tap anywhere to see how many audited units on that spot have cooling — and what kind. Blue means Seine-chilled district water: green, quiet, and capped at 26°C by law. Purple means a private plant, which is how a lobby ends up arctic.

How to read this. Search an address or tap the map, and FROID queries France's DPE energy-audit database for every unit recorded at that spot, then colours each one: blue if it's cooled by water off the district loop, amber for a split or heat pump, pale grey for no cooling on record.
The twist: French law forbids cooling a commercial space below 26°C (~79°F). District-connected buildings can't cheat it, and the loop's water even warms slightly in a heat wave. A private plant, quietly set to 20°C, is against the rules and gloriously cold — which is exactly what you felt.
Landmarks — palaces, grands magasins & museums
Hand-researched: dark blue where the network operator publicly names the building as a client, purple where it's off the loop and big enough to run its own arctic plant.
