Ventilate · At the right time

About

Ventilate provides serene and practical support to keep you comfortable in hot weather. After a single setup of your windows and entering your indoor temperature—a thermometer is useful but optional—you receive straightforward instructions on when to shut windows to block heat, when to open them for ventilation, and optimal fan placement to direct cool air toward you. It offers customized suggestions for each window using local weather and orientation, along with mild reminders and a collection of heat management tools.
