Aloha, E Komo Mai!

Welcome to the ASHRAE Hawaii Chapter Website 



ALOHA - President’s Message - May 2018

Aloha members of the Hawaii ASHRAE community.

Many of you probably remember the great presentation on natural refrigerants by Danielle Wright at our February Chapter Meeting.  One of her discussion points was how propane is one of the most efficient refrigerants with next to zero GWP and ODP but its use is being limited by regulation like ASHRAE Standard 15.  One way we can help modify this regulation is by signing the petition on this website.  This is a very simple task that could bring about great change.

It was another eventful month for ASHRAE in April with three activities taking place.  The month started off with our chapter meeting.  In the Technical Presentation by Mario Martucci of Friedrich, he discussed their new PTAC unit that can provide fresh air that meets the latest requirements of ASHRAE 62.1.  The unit also has a variable speed compressor and EC motor on the fan.  I never thought I would say something took PTAC’s to the next level but this would be the one.

The main presenter of the seminar was Distinguished Lecturer Ray Patenaude who discussed the best methods to control humidity and mold in our climate.  This has been one of the biggest threats to any engineer working in Hawaii after the Hilton Hawaiian Village Kalia Tower issue.  Mr. Patenaude discussed the importance of having a properly designed building envelope which is something we might neglect when we are working on our HVAC system.  ASHRAE 90.1 even has mandatory building tightness of 0.4 CFM/ft2 at 0.3 in. water gauge.  Don’t forget to ensure the architect meets this on your next project.

We had another refrigeration tour set up by Jeanessa Slaughter last month.  This time the tour was at Beer Labs Hawaii and we got to see their beer making process up close.  Even though the tour was brief, the gathering afterward lasted multiple hours sampling some of Beer Lab’s finest brews.

The last event of April was the Earth Day clean-up at Waimanalo Beach set up by Joe Palaszynski.  Although we only had 6 ASHRAE members participate, the event made the most impact by helping Hawaii clean up its most precious resource.  Joe and I even powered the event for a while on with the bikes that were tied into a battery.  Hopefully we get many more to participate next year since this will be a yearly event.

Look forward to seeing everyone at the annual golf outing on May 4th and then the last chapter meeting of the year on May 10th.  The ASHRAE year has gone well so far so let’s maintain the momentum and finish strong.
