Install them on the coolest side of your house to bring in fresh air, or on the warmest side to expel hot air.
Whole-house fans, typically installed in the attic, are powerful tools for night purge cooling.
They work by pulling cool outside air through open windows and exhausting hot air through the attic and roof vents.
To maximize their effectiveness:
- Turn on the fan when outdoor temperatures drop below indoor temperatures
- Open windows on the lower floors to create a path for cool air
- Close windows and shut off the fan in the morning to trap the cool air
- Maintain proper attic ventilation to prevent moisture buildup
Cross-Ventilation Techniques
To maximize the efficiency of night purge cooling, implementing effective cross-ventilation techniques is essential. Cross-ventilation creates a natural airflow through your home, helping to flush out warm air and bring in cooler night air. To achieve this, you'll need to strategically open windows on opposite sides of your house.
Start by identifying the prevailing wind direction in your area. Open windows on the windward side to let cool air in, and on the leeward side to allow warm air to escape.
If you have a multi-story home, open lower windows on the cooler side and upper windows on the warmer side to create a chimney effect.
You can enhance cross-ventilation by removing obstacles that block airflow, such as furniture or heavy curtains. Consider installing window screens to keep insects out while allowing air to flow freely.
If your home's layout doesn't naturally support cross-ventilation, you can use interior doors to create pathways for air movement. Keep doors open between rooms to allow air to circulate throughout the house.
