About this app

Opening your windows on a cool summer night is a great way to cool your home while saving both money and energy on air conditioning. This app helps you to make intelligent and predictive decisions to know when to open and close your windows at the right time to optimize your cooling efforts according to your preferences.

This app looks at current and forecast weather conditions and compares them to your home’s current conditions. It analyzes temperature, dew point, and the possibility of rain over time. You choose how aggressive your window opening strategy is, and it does the math for you to tell you the best times to open and close your windows and why.

The app is free to use and can help you to minimize your air conditioning usage to save on your utility bills. Studies have estimated that a good window opening strategy can reduce air conditioning energy consumption by as much as 30%. It's a great way to bring fresh air into your home, cool it down quickly when conditions are favorable, and help you to sleep better. It can even tell you when to open your windows on an unseasonably warm day.

Now's your chance to save money while enjoying a natural breeze in your home, and at the same time, minimizing your carbon footprint!
