    <description><![CDATA[<p>If every building had a white roof, we would be able to cool the surrounding areas. That is <strong><a href="http://HeatIsland.LBL.gov" target="_blank">the reasoning</a></strong> behind a California law about to go into effect next month <strong><a href="http://www.energy.ca.gov/2008publications/CEC-999-2008-031/CEC-999-2008-031.PDF" target="_blank">requiring light reflective roofs on all new buildings</a></strong>. It is already the law for new flat roofs here.</p>
<p><a href="http://greenbuildingelements.com/files/2009/06/meier1.jpg"><img class="aligncenter size-full wp-image-1170" src="http://go635254.s3.amazonaws.com/greenbuildingelements/files/2009/06/meier1.jpg" alt="" width="500" height="469" /></a></p>
<p>Here, architect <strong><a href="http://www.richardmeier.com/current/">Richard Meier</a> </strong>and his partner Michael Palladino have apparently created a design to go one further. It&#8217;s entirely white; roofs, walls, and interiors.</p>
<p><a href="http://greenbuildingelements.com/files/2009/06/meier2.jpg"><img class="aligncenter size-full wp-image-1171" src="http://go635254.s3.amazonaws.com/greenbuildingelements/files/2009/06/meier2.jpg" alt="" width="500" height="501" /></a></p>
<p>So this luxury design of a cool  and airy Southern California beach house is glamorous <em>and</em> climate friendly.</p>
<p><a href="http://greenbuildingelements.com/files/2009/06/meier3.jpg"><img class="aligncenter size-full wp-image-1172" src="http://go635254.s3.amazonaws.com/greenbuildingelements/files/2009/06/meier3.jpg" alt="" width="500" height="461" /></a><br />
Well, no. The McMansion-sized size of the thing at  4,280-sq.-ft is <em>not</em> so planet friendly; because it takes more energy to heat and cool a larger space. But this house would be well suited for a <strong><a href="http://greenbuildingelements.com/2008/05/20/greenbuildingtalk-save-money-on-your-heating-and-cooling-bill-with-geothermal/" target="_blank">ground heat exchange</a></strong> to passively heat and cool itself with 55 degree air cooled from 10  feet <strong><a href="http://greenbuildingelements.com/2009/06/09/buffalo-house-to-weather-rainstorms-in-kansas/" target="_blank">under the ground.</a></strong></p>
<p>As architects in California get closer to 2020, they will need to think more about <strong><a href="http://greenbuildingelements.com/2009/02/06/more-news-on-the-cool-bird-island-design-previews/" target="_blank">passive cooling </a></strong>and heating and <strong><a href="http://greenbuildingelements.com/2009/06/03/zero-energy-houses-creating-a-new-design-vernacular/" target="_blank">zero energy houses</a></strong>, as that will be the law by 2020. All new building must be zero energy by then.</p>
<p>Incorporate <a title="solar roof" href="http://1bog.org/choosing-a-solar-installer-can-be-tough/">solar roofing</a> on the white roof, and this could be a zero energy house.</p>
<p><a href="http://greenbuildingelements.com/files/2009/06/meier4.jpg"><img class="aligncenter size-full wp-image-1173" src="http://go635254.s3.amazonaws.com/greenbuildingelements/files/2009/06/meier4.jpg" alt="" width="500" height="489" /></a><br />
The blue of a solar roof would visually extend right out to the ocean. (And conceal that horrible mess of  mechanical contraptions on that roof.) White elastomeric cool roof paint under the <a href="http://cleantechnica.com/2008/02/07/how-to-cheap-or-free-solar-panels/">solar panels</a> would help cool the modules making them more efficient on hot days.</p>
<p>But <em>are</em> architects thinking about these things?</p>
<p>With 2020 almost upon us:  <em>“The beams at the roof, located above the horizontal framing, express the structural rhythm and layering of components,” </em>explains the architect. <em>“This cadence is repeated with the joinery of the painted aluminum exterior wall panels and modular windows. The mass of the exterior plaster walls are juxtaposed to the transparent glazed facades, creating a mosaic of layered materials.”</em></p>
<p>Blah, blah, blah.</p>
