Passive House Solar Shades

The Passive House is designed to achieve maximum solar heat gain by orienting its largest windows with southern exposure with the intent of providing at least 50% of the building’s heating demand. While this works well in the winter months when the low angled sun radiates heat into the space, this solar radiation becomes excessive during the summer months and needs to be shaded. InSync Solar provides both exterior and interior shades with the needs of the Passive House in mind.

Exterior Shades for The Passive House

The most effective way to prevent too much solar heat gain from entering through the windows is with exterior window shades. Exterior window shades are an excellent solution because of its superior performance in reducing solar heat gain. The graphic below tells it all. A space with no shades allows 80% solar heat gain to enter a space. An interior shading solution offers better results blocking over 50% of the solar heat gain. However, for maximum results nothing beats an exterior window shade, which blocks over 85% of solar heat gain.

The Zip Shade is a breakthrough design that is revolutionizing the window shade industry. We call it a Zip Shade because a zipper-like locking device is welded to the fabric edges. The zipper slips into a side channel that keeps the fabric from falling out. The bottom hem-bar is weighted so when the shade is completely closed the fabric provides a drum like cover to the window. Read More

Interior Shades for The Passive House

Even though exterior shading solutions are preferred, they may not be possible for a variety of reasons, such as, “we never planned for exterior shades, now it’s too late”, or “we don’t have a budget for motorized shades”, or just simply “we don’t want exterior shades, we want interior shade”.
