Hi there, Nicolas! While the room temperature will have a bit of an impact on how fast the starter ripens, a healthy starter will likely still double in size within 6 to 8 hours even in a cooler room. If your starter is very active and your kitchen is warmer (up around 75°F), it'll become ripe faster so you'll want to keep an eye on it. We hope this helps to clarify and happy baking!
