Well it is usually the case that people start to notice ways in which a certain view or interpretation of something doesn&rsquo;t make sense. Then eventually someone takes this evidence and makes a strong argument in support of a new way of viewing or interpreting something, and this leads people to stop viewing/interpreting the issue or event in the old way and to adopt this new perspective. &mdash; from<a href="" target="_blank" title="HVAC industry Paradigm Shift"> Paradigm Shifts in Vietnamese&nbsp;History</a></p> Weil I'm Thinking of It: Some Thoughts on the Aftermath of the HVAC Industry's AHR Expo <div class="node-body article-body">The 2014 AHR Expo had a different kind of buzz, one that focused on HVAC systems instead of products.</div> <p><a href="" target="_blank">read more</a></p> AHR Expo Mike Weil Mon, 10 Feb 2014 19:00:00 +0000 12031 at <p>Opening day of the <strong><a href="" target="_blank" title="The Jacom-Javits Center, 2014 AHR Expo">2014 AHR Expo</a></strong> saw crowds gathering as a winter strom prepared to descend on New York City.

Local utility companies produce power on a large scale at a distance from sources of usage, with as much as 25 percent of the energy lost during delivery. Using the same natural resources, cogeneration plants eliminate those losses and function in excess of three times more efficiently than local utility companies.</div> <p><a href="" target="_blank">read more</a></p> Managing Facilities Fri, 07 Feb 2014 18:33:00 +0000 11971 at
