Such roofs can be decorated with plants, painted white to better reflect the sun&#8217;s rays, or coated with materials that are both highly reflective and highly emissive (<em>SN: 2\/6\/23<\/em>).<\/p>\n\n\n\n<p>Vertical walls are more difficult to cool, says materials scientist Yuan Yang of Columbia University. This is because they are not only directed from space, but simultaneously absorb heat from the ground. An efficient radiant cooling design must take into account both effects.<\/p>\n\n\n\n<p>Hence: zigzag walls. Yang&#8217;s team hypothesized that by undulating the vertical surface and coating the sides with different materials \u2014 more reflective materials facing down and more emissive materials facing up \u2014 the wall could absorb less heat than a conventional straight wall. .<\/p>\n\n\n\n<p>Simulations comparing how much heat conventional and zigzag walls received from the ground during a hot day supported this hypothesis. The average difference in wall temperature was about 2.3 degrees, a difference that increased to 3.1 degrees during the hottest part of the day. The team found a similar difference when they tested a miniature backyard version of their design in the summer of 2022 in New Jersey.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">How zigzags affected the temperature of a wall<\/h5>\n\n\n<figure class=\"wp-block-image \"><picture class=\"sn-responsive-image\"><source srcset=\"https:\/\/i0.wp.com\/www.sciencenews.org\/wp-content\/uploads\/2024\/08\/080924_cg_zigzag-wall_inline_desktop.png?w=680&amp;ssl=1 680w, https:\/\/i0.wp.com\/www.sciencenews.org\/wp-content\/uploads\/2024\/08\/080924_cg_zigzag-wall_inline_desktop.png?resize=330%2C151&amp;ssl=1 330w\" width=\"680\" height=\"311\" media=\"(min-width: 600px)\" sizes=\"(max-width: 1023px) 100vw, 680px\"><source srcset=\"https:\/\/i0.wp.com\/www.sciencenews.org\/wp-content\/uploads\/2024\/08\/080924_cg_zigzag-wall_inline_mobile.png?w=680&amp;ssl=1 680w, https:\/\/i0.wp.com\/www.sciencenews.org\/wp-content\/uploads\/2024\/08\/080924_cg_zigzag-wall_inline_mobile.png?resize=659%2C383&amp;ssl=1 659w, https:\/\/i0.wp.com\/www.sciencenews.org\/wp-content\/uploads\/2024\/08\/080924_cg_zigzag-wall_inline_mobile.png?resize=320%2C186&amp;ssl=1 320w\" width=\"680\" height=\"395\"><img decoding=\"async\" src=\"https:\/\/www.sikviral.com\/wp-content\/uploads\/2024\/09\/Zigzag-walls-can-help-buildings-beat-heat.png\" class=\"attachment-large size-large\" alt=\"Graph showing how zigzag walls stayed cooler than flat walls in a field test experiment.\" srcset=\"https:\/\/i0.wp.com\/www.sciencenews.org\/wp-content\/uploads\/2024\/08\/080924_cg_zigzag-wall_inline_mobile.png?w=680&amp;ssl=1 680w, https:\/\/i0.wp.com\/www.sciencenews.org\/wp-content\/uploads\/2024\/08\/080924_cg_zigzag-wall_inline_mobile.png?resize=659%2C383&amp;ssl=1 659w, https:\/\/i0.wp.com\/www.sciencenews.org\/wp-content\/uploads\/2024\/08\/080924_cg_zigzag-wall_inline_mobile.png?resize=320%2C186&amp;ssl=1 320w\" sizes=\"(max-width: 1023px) 100vw, 680px\" data-attachment-id=\"3142307\" data-permalink=\"https:\/\/www.sciencenews.org\/080924_cg_zigzag-wall_inline_mobile\" data-orig-file=\"https:\/\/www.sikviral.com\/wp-content\/uploads\/2024\/09\/Zigzag-walls-can-help-buildings-beat-heat.png\" data-orig-size=\"680,395\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"080924_cg_zigzag-wall_inline_mobile\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Researchers tested a small-scale version of their zigzag wall design during New Jersey\u2019s summer heat, and tracked changes in ground, air and wall temperatures.
