The simple act of opening a window can often provide immediate cooling effects. But how do the size and placement of that window impact the effect you feel? Window design and ventilation louver design greatly affects passive cooling potential, specifically natural ventilation.
Natural ventilation can still be an option even in hot climates, particularly in hot dry climates. Two techniques can be used to cool incoming air: Evaporative cooling and geothermal cooling.
Just like passive heating, cooling your building using passive strategies is important for reducing energy usage in your building. Specifically, utilizing passive cooling strategies like natural ventilation, air cooling, and shades can reduce your demand for mechanical cooling while maintaining thermal comfort.
Airflow and air quality is an important aspect of human comfort. Moving air helps people feel cooler, and natural ventilation is a key strategy for passive cooling. Also, circulating fresh air within a space prevents air from getting stale. In building design, you’ll want to consider both external and internal airflows.
A building's immediate surroundings change its effective weather patterns, as nearby buildings or trees can block sunlight and change wind patterns.
