He keeps the whole house shaded using these techniques:<\/p>\n<ul>\n<li>The south facing single slope roof has on overhang on the south that keeps the south wall in shade most of the day.<\/li>\n<li>The north side of the house is shaded by an roof extension sloped down to the north that shades the north side of the house most of the day.<\/li>\n<li>The roof is double layered with airflow between the well spaced layers. \u00a0This greatly reduces solar heat gain through the roof.<\/li>\n<li>The east and west walls of the house are double wall construction with a couple feet between the walls. \u00a0The shading that the outer wall offers plus airflow between the double walls keep the wall temperatures low.<\/li>\n<li>In addition, he has worked out ways to take advantage of the night<br \/>\ntemperature drop and to use thermal mass on the basement to provide some<br \/>\ncooling.<\/li>\n<\/ul>\n<p>More: <a href=\"http:\/\/www.builditsolarblog.com\/2013\/09\/a-unique-passively-cooled-home-in.html\" target=\"_blank\">A unique, passively cooled home in the Tropics<\/a> (Build-It-Solar), <a href=\"http:\/\/kotaronishiki.com\/\" target=\"_blank\">Passive Solar House in Tropical Areas<\/a> (Kotaro Nishiki).
