Most of the heat enters buildings through windows and skylights. This can happen through direct sunlight as well as through opening windows and doors.

Tips

• Keep the mechanical ventilation system running and try to keep windows closed during extremely hot or cold periods.
• Take advantage of cool nighttime air to cool down the building. You can open windows to allow for refreshing airflow.
• Prevent heat gain from direct sunlight by keeping external shading devices closed when the sun is shining.

Benefits of Mechanical Ventilation in Summer
Mechanical ventilation should be operated continuously, 24/7, and 365 days a year, ensuring a constant supply of fresh outdoor air into the house. Studies have shown that the heat gain through ventilation is minimal, and there is no need to open windows during hot hours.
Additionally, mechanical ventilation removes excess moisture from bathrooms and kitchens, contributing to a more comfortable indoor environment.

*Please ensure that comfort is not compromised, and health is not affected when utilizing these tips.
