Quick Answer
Window placements play a crucial role in passive solar homes by allowing natural light and heat to enter the building, reducing the need for artificial lighting and heating. Strategically positioned windows can absorb and distribute solar radiation, warming the interior during cold months and cooling it during hot months. Proper orientation is key to maximizing passive solar benefits.
Window Placement Strategies
In earthship homes, where passive solar design is a cornerstone, window placement is a deliberate process. Typically, windows are placed on the south side of the building, often between 10 and 15 degrees from true south. This orientation allows the windows to capture the lowest winter sun angle without overheating in summer. The angle and position of windows can also be adjusted to account for local climate conditions.
Earthship Window Design
Earthships often feature large south-facing windows, often 2.5 to 3 meters tall, to maximize solar gain. These windows are typically designed with overhangs to prevent summer solar radiation from entering the building. The overhangs are usually 1 to 2 meters deep, and some earthships may feature a second roofline to create an additional overhang, increasing summer shading and reducing heat gain.
