If we observe the current home design trends in Indonesia, one common feature is the heavy reliance on air conditioning (AC). This often results in homes with tightly sealed doors and windows to prevent cool air from escaping. However, one advantage of living in a tropical country like Indonesia is the stable year-round temperature, which allows for open house designs that do not rely entirely on AC.
Take a look at homes built several decades ago—ventilation elements were always present, whether above doors and windows or along certain walls. These controlled openings help direct airflow from outside, ensuring a continuous exchange of air within the house. When combined with shaded areas that block direct sunlight, this natural ventilation keeps indoor spaces cool and comfortable.
The problem is that modern house designs often mimic those from four-season countries, where ventilation features are uncommon. For example, aluminum doors and windows rarely come with built-in ventilation options. Additionally, homeowners often prefer tightly sealed designs to keep out dust and insects like mosquitoes.
The primary reason to incorporate ventilation in modern home design is energy efficiency and environmental sustainability. Proper ventilation can significantly reduce, or even eliminate, the need for AC. It also helps control humidity, prevents lingering odors in kitchens and bathrooms, and ensures a healthier indoor environment—especially important in the post-pandemic era, where fresh air circulation is crucial.
A common solution for homes with aluminum doors and windows is adding insect screen layers, allowing them to be opened without letting in pests. Another option is custom-built grilles installed at the top or bottom of aluminum doors and windows, seamlessly blending with the design. In some cases, ventilation is integrated separately from doors and windows, such as through façade wall openings.
For a cleaner and more minimalist look, TOSTEM offers the AirFlow System, which integrates ventilation into aluminum door and window products. This system features an adjustable valve that can be opened or closed as needed, allowing flexible ventilation control while preventing water leakage during rain. This system is available for the WE Series. Additionally, TOSTEM provides integrated insect screens that can be fully opened, partially opened, or completely closed for enhanced airflow management.
With benefits like energy efficiency, improved air quality, and weather-tight sealing when closed, the TOSTEM AirFlow System is the ideal choice for tropical home designs that prioritize both functionality and modern aesthetics.
