Scott Arnold's Blog The thoughts and musings of HPAC Engineering Executive Editor Scott Arnold. en Ebert’s Law and Engineering Content <div class="node-body blog-body">In film reviews and his Movie Answer Man column, critic Roger Ebert would remind readers of Ebert’s Law, which states: “A movie is not about what it is about. It is about how it is about it.” At HPAC Engineering, we have been thinking a lot about how our content is about what it is about, which has inspired us to experiment with content forms not typically seen in technical publishing, the latest being "Choose Your Own (HVAC) Adventure," inspired by the popular series of interactive gamebooks for younger readers.</div> <p><a href="" target="_blank">read more</a></p> Air Conditioning Building Controls Fire / Smoke Heating Humidity Control IAQ & Ventilation Motors / Drives Piping / Pumping Scott Arnold&#039;s Blog Fri, 30 Sep 2016 17:29:00 +0000 28981 at 'Lunching and Learning': Food for Thought on Campus Chilled-Water Design <div class="node-body blog-body">In "Lunching and Learning: A Civil Engineer’s View of a Campus Chilled-Water System," a fictional conversation about a system that may or may not be in existence is presented to, in the words of the author, “plant the seed of an idea with people (who) might actually implement” it and start a (real) discussion. </div> <p><a href="" target="_blank">read more</a></p> Air Conditioning Scott Arnold&#039;s Blog Sun, 02 Aug 2015 22:44:00 +0000 17901 at The Return of Johnny Tundra, Cold-Weather Engineer <div class="node-body blog-body">Fifteen years ago, Ron Wilkinson became a commissioning authority. At the time, most commissioning case studies focused on problems of moisture incursion in air-conditioned buildings in hot and humid climates. Ron wanted to call attention to cold-weather problems in Northern Tier states and do it in a way “that was fun and that described the American ‘can-do’ attitude in the context of actual engineering problems.” The result: a series of mystery/adventure stories starring the “troubleshooter from Big Timber,” Johnny Tundra.</div> <p><a href="" target="_blank">read more</a></p> Heating Scott Arnold&#039;s Blog Fri, 01 May 2015 15:50:00 +0000 16951 at Ebola Outbreak Puts Hospital Protocols Under the Microscope <div class="node-body blog-body">If you have picked up a newspaper, logged on to a news site, or turned on the evening news of late, you no doubt are aware of the recent epidemic of Ebola virus disease.</div> <p><a href="" target="_blank">read more</a></p> Archive Scott Arnold&#039;s Blog Thu, 13 Nov 2014 18:14:00 +0000 14571 at HVACR Content: The Gift That Keeps on Giving <div class="node-body blog-body">In 1975, Bill Acker was fresh out of college, working as an engineering draftsman. He was hired to do industrial HVAC work, but soon was asked to engineer steam and condensate return, compressed-air, and paper-machine piping, as well as boiler and steam-turbine systems. “I did not know how to do a lot of this work,” Bill recalled recently, “so I had to learn fast by utilizing other engineers.”</div> <p><a href="" target="_blank">read more</a></p> Archive Scott Arnold&#039;s Blog Thu, 09 Oct 2014 18:05:00 +0000 14301 at Urine Power: The Wave of the Future? <div class="node-body blog-body">When it comes to sustainable energy sources, I have heard of wind, I have heard of solar, and I have heard of geothermal.
