Colin E. Laisure-Pool, P.E., CEM, LEED-AP

Colin is a Sales Engineer at Mechanical Products Southwest in Phoenix, AZ. He joined MPSW in January of 2019, after a 17-year career as a consulting engineer. A 3rd-generation AZ native and graduate of the University of Arizona (BSE in Engr Physics), he has spent the majority of his HVAC design career in all sectors of the building industry; ranging from residential, to retail/commercial, to semiconductor, to mission-critical facilities data centers.

Mr. Laisure-Pool currently serves on the Central Arizona ASHRAE Chapter Board of Governors, and is current Region X RVC of the GAC (Government Affairs Committee). He served as Central AZ Chapter President in 2014.

Extreme Design Conditions

Weather and site conditions in Arizona, specifically the Phoenix & Tucson Metro area, pose unique challenges to the HVAC engineer. Some widely-held misconceptions about our climate and conditions (usually held by those not from or living here) can have detrimental effects on HVAC performance and building operation. The sentiment that ‘Phoenix is easy; there’s no seismic, no humidity, and no snow’ is not entirely accurate. This presentation is intended as a sharing of experiences and open-forum discussing the challenges we face in our industry, on the design, construction, and operation sides.

Topics will include:

-              Dry-bulb design temp: Use 108F per ASHRAE, or 120F?  (follow ASHRAE, or keep your license?)

-              Wet-bulb design temp & the effects of our monsoon season (so much for the ‘dry heat’).

-              Dust control. ‘Haboob’ mitigation

-              Hard water issues/water treatment challenges

-              Cold snaps/short-term freezing conditions in the rural desert

Hoy Bohanon, PE, LEED AP, BEAP 

Hoy Bohanon, PE, LEED AP, BEAP is principal in Hoy Bohanon Engineering, PLLC, a firm that focuses on improving the performance of existing mission critical buildings.  Mr. Bohanon began his engineering career as a research and design engineer, and then gained experience as a project engineer, facilities engineer, facilities manager, indoor air quality research engineer, environmental engineer, and business owner. He has a master’s degree in engineering from North Carolina State University, and a bachelor’s degree in mechanical engineering from Georgia Institute of Technology. 

Mr. Bohanon has written technical papers and articles on indoor air quality, operations, and maintenance and is a frequent presenter at technical society meetings. He is a recipient of the ASHRAE Distinguished Service Award and is chair of ASHRAE Standard 62.1 committee, Ventilation for Acceptable Indoor Air Quality.  He also serves on the bEQ committee,. He is chair of the US Technical Advisory Group panel 1 (general principles) and panel 4 (indoor air quality) for ISO TC205 Building Environment Design.  He is a co-author of The Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning and Performance Metric Protocols for Commercial Buildings: Best Practices Guide. He also teaches multiple courses for the ASHRAE Learning Institute addressing ASHRAE 62.1 and IAQ.  Mr. Bohanon is also a member of the Professional Engineers of North Carolina, US Green Building Council, and I2SL.

Perception and Acceptance of Commissioning

Building commissioning has been around for more than a decade. Commissioning is required by certain sustainability rating programs, certain government entities, and some private sector owners. ASHRAE has published ANSI/ASHRAE/IES Standard 202-2013 as the first national standard for commissioning. How is commissioning perceived and accepted in the marketplace?

Standard 202 is a process standard. How is a process standard different from a prescriptive standard? What is the difference in commissioning to a standard versus other activities that are called “commissioning”? Will following the national standard change either the perception of acceptance of commissioning?

Commissioning is a quality assurance process for building design construction and operation. What can we learn from other quality assurance processes such as ISO 9000? How do lessons from case studies apply to commissioning practice?
