Hanesbrands’ sock manufacturing facility in San Juan Opico, El Salvador, opened in March 2009. This 450,000-square-foot facility has 1,000 employees who knit, bleach, dye, board, and pack millions of pairs of socks annually. The facility was designed with a variety of features to save energy, including:</p>
<ul class="clear"><li>
              Skylights to maximize the use of natural light.
            </li>
<li>
              Daylight harvesting, which is the use of digital photo sensors to detect daylight levels and automatically adjust the interior electric lighting to create a balance.
            </li>
<li>
              <abbr title="light-emitting diode">LED</abbr> technology for task lighting for work that requires a higher light level.
            </li>
</ul><p>These lighting features alone will avoid nearly 4 million kilowatt-hours per year, saving approximately $380,000 per year.</p>
<p>The facility is one of the first <abbr title="Leadership in Energy and Environmental Design">LEED</abbr>-certified apparel manufacturing facilities in the world.</p>
<p>Enerim, Ltd. performed the energy modeling for the project.
