Reading lamps

When I posted a photo of the west facade of the Rizal Library in the Ateneo de Manila University with its sparse windows, someone commented that she doesn't like buildings without windows. In fact, it is only the east and west sides that have few windows so that the interiors do not get the full strength of the sun's heat. If you've ever stayed in equatorial countries during their summers, you can understand why this architectural design principle makes a lot of sense. However, the north and south sides of the library are almost nothing but windows, providing lots of natural light in the reading rooms during the day. Of course, they still have to use fluorescent lamps at night.
