Sun- and Shade-Harvesting Mirror
These images illustrate how a mirror on hinges on the interior of my garottage’s west wall carries out multiple functions: letting us direct the winter sun where we want it, protecting books from sun bleaching, and doubling the view through the window in the adjoining south wall’s door, all while avoiding the unwanted heat gain that would result from a window installed facing the hot afternoon sun in the west. These photos were all taken within one minute of each other on a late morning in winter.
