President's Report

The President’s Message

By:  Ron McCarty

Reminder that our next meeting will be on April 3rd at Camp Aldersgate.

It is hard to believe that we are coming down to our last meeting for the 2018-2019 year. So far, this year has exceeded expectations with significant growth in meeting attendance and overall participation within the various groups and Committees. March’s meeting continued to exceed expectations with another record attendance. For the March meeting our Chapter was able to continue our tradition to have the honor of the current ASHRAE President (Sheila J. Hayter, P.E.) in attendance and to have her present this year’s President’s vision. Following our monthly meeting our Refrigeration Committee in conjunction with YEA and Membership Promotions held a facility tour at Zero Mountain’s refrigeration expansion. The event was followed up with a social event at Diamond Bear Brewing Co.

The months of April and May are going to finish our year with a bang. Events start with Student Career Fair (4/4), Trap Shoot (4/19), Past Presidents Night (5/9) and our Spring Golf Tournament (5/10). In addition to local chapter events we have the Region VIII Chapter Regional Conference in Cancun Mexico on April 11-13, 2019.

As indicated above our next meeting is on April 3rd at Camp Aldersgate. Our guest speaker is Dr. Marwa Zaatari and her topic will be "ASHRAE Standard 62.1-2019 Updates to IAQP". Please register and plan to attend our last meeting for the year.

RP is in full swing with trying to meet our Chapter donation goal. Upcoming addition RP events include the “The Sportsman’s Raffle” and Trap shoot event (April 19th). Please support these events so that we can meet our Chapter goal.

As always, each month I personally want to thank everyone that gives their time and effort to help make our Chapter great. I am specifically thankful to all of our Arkansas ASHRAE volunteer officers, committee chairs, and committee members whom have worked so hard for our Chapter to bring value to your membership.

Chapter Meeting Announcement

Arkansas ASHRAE Chapter Meeting

Hosted By: Arkansas ASHRAE Board of Governors

Agenda for Wednesday, April 3rd:

10:30-11:30   Board of Governors' meeting
11:30-12:00   Lunch Buffet and Announcements
12:00 - 1:00   ASHRAE Standard 62.1 - 2019 Updates to IAQP by Dr. Marwa Zaatari

Speaker Spotlight:

Dr Marwa Zaatari is Vice President of Building Solutions at enVerid Systems since 2015. She leads design of ventilation and filtration/sorption systems in buildings, manages filtration/sorption systems installations and integration into HVAC systems, energy and indoor air quality protocol development and field measurements and monitoring. Prior to this, Marwa worked as a consultant for Trinity Consultants where she prepared state and federal air quality permit applications for various industries, including chemical factories, oil and gas production, among others.  Marwa holds a Ph.D. degree in Environmental Engineering from the University of Texas at Austin in 2013. Her interests and research have focused on energy efficiency, indoor air quality, measurement and modeling of indoor pollutants, human exposure assessment, and HVAC filtration and sorption.  Marwa is a member of several ASHRAE Committees, voting member of ASHRAE Standard 62.1, voting member of TC2.3 and Standard 145.2.  She is the ASHRAE Chair of the Indoor Air Quality Procedure (IAQP) Working Group, a LEED Committee member, and Chair of LEED IAQP Working Group. 

Key Learning Objectives:

  1. Overall Direction for Modifications to Standard 62.1
    • SSPC 62.1’s mission is to maintain a design standard providing ventilation procedures for acceptable indoor air safety and quality for the built environment. After a year of discussions, the committee made an important decision. That decision is to make the quality of indoor air more comparable between the different pathways. This presentation addresses the modifications to ASHRAE standard 62.1. 
  2.    The New IAQP
    • This presentation discusses the design requirements of the New IAQP. Those requirements include; identification of contaminants of concern, determining indoor and outdoor sources, identifying a concentration limit and exposure period, specifying percentage of building occupants to be satisfied with perceived IAQ and performing a mass balance analysis for selected compounds. 
  3.    Major Changes to the VRP and NVP
    • Ventilation Rate Procedure is the prescriptive design procedure presented in Section 6.2, in which outdoor air intake rates are determined based on space type/application, occupancy level, and floor area, shall be permitted to be used for any zone or system. Informative Note: The Ventilation Rate Procedure minimum rates are based on contaminant sources and source strengths that are typical for the listed occupancy categories. The requirements for atypical sources are spelled out in new addenda. There is a simplified VRP that incorporates a default Ev. This helps designers who do not wish to perform the more complex calculations in Appendix A. The use of this simplified procedure is described.
    • The natural ventilation procedure has changed over the years in 62.1. It was relocated from section 5 to section 6 and became a ventilation procedure. It was recently modified to require mechanical ventilation with certain exceptions. This addendum provides specific requirements for the exception by providing a clear compliance path. It also recognizes that there are inherent health issues with outdoor air in many locations in the world and updates the prescriptive requirements based on recent studies and airflow evaluations.
