#DIY Seasonal Mirror-Based #WindowExtender for Heat and Light

"The core concept is that, by mounting a mirror roughly perpendicular to the bottom of a south-facing window, it reflects sunlight that would have fallen on the insulated exterior of the building through the window instead. With the right sized mirror and mounting hardware, the functional 'size' of the window for solar gain calculations could be increased by almost 50%, potentially providing Burlington, Vermont windows with Boulder, Colorado performance!"

Use window boxes to support the mirrors in winter

In summer the window boxes grow vines for cooling shade
