Clark's Remarks http://hpac.com/blog/9271/feed The thoughts and musings of Lawrence (Larry) Clark, principal of Sustainable Performance Solutions LLC. en HVAC and Electric Motors http://hpac.com/blog/hvac-and-electric-motors <div class="node-body blog-body">A multistory commercial office building has a relatively new 1.5-ton split system that cools the elevator equipment room. When the building’s maintenance staff discovered the system was not running and the temperature in the equipment room was abnormally high, an A/C service tech was dispatched. The service tech was unable to find any malfunction in the equipment, but when he measured the voltage on the single-phase circuit serving the condenser and air-handler units, it was 197 with no major loads.</div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/clarks-remarks">Clark&#039;s Remarks</a></li> </ul></div><p><a href="http://hpac.com/blog/hvac-and-electric-motors" target="_blank">read more</a></p> http://hpac.com/blog/hvac-and-electric-motors#comments Motors / Drives Clark&#039;s Remarks Wed, 24 Jun 2015 14:17:00 +0000 17521 at http://hpac.com <p>Todd Arena/Hemera</p> Laboratory Water Efficiency http://hpac.com/blog/laboratory-water-efficiency <div class="node-body blog-body">Since its inception in 2010, our firm has had the opportunity to work with several major research laboratories, which has given us first-hand insight into the unique characteristics and challenges of labs as a building type.</div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/clarks-remarks">Clark&#039;s Remarks</a></li> </ul></div><p><a href="http://hpac.com/blog/laboratory-water-efficiency" target="_blank">read more</a></p> http://hpac.com/blog/laboratory-water-efficiency#comments Piping / Pumping Clark&#039;s Remarks Tue, 09 Jun 2015 14:24:00 +0000 17231 at http://hpac.com <p>Alexander Traksel/iStock</p> The Role of School HVAC in Student Performance http://hpac.com/blog/role-school-hvac-student-performance <div class="node-body blog-body">Green schools report lower absenteeism, better academic performance, and less faculty turnover.
