The Art of Commissioning

Our series concludes with a focus on the pivotal role of heat pump commissioning, ensuring you have a complete end-to-end understanding of HVAC systems. After considering design and real-world applications, commissioning is an imperative final step to ensure optimal system operation, longevity, and client satisfaction.

Our veteran hosts, Bruce Manclark and Matt Ryan, will once again steer us through this intricate process and provide insights into why commissioning is paramount. Marc Cregeur from Earth Advantage will introduce the RESNET Standard 310 as an alternative pathway to meet ENERGY STAR requirements and unlock the 45L Tax Credit. And, bringing a final holistic perspective to the table, Mike Frey of Noyes Development will share a builder's view on the benefits of a well-commissioned system, emphasizing ENERGY STAR compliance and the consequential tax credit advantage.

With foundational design tools such as Manuals J, D, and S serving as the blueprint, the importance of commissioning centers on verifying the installation adherence to this design. The process goes beyond mere checks; it's about quality control, reducing callbacks, and achieving a heightened standard across the board - from installers and designers to commissioners and verifiers. The end goal? Satisfied customers basking in the efficiency of a well-commissioned system.

Delving deeper, Matt will touch upon specific tools integral to commissioning and discuss the: 

  • Significance of TruFlow plates and manometers in measuring equipment airflow
  • Role of velometers for granular room-by-room air assessments
  • Indispensability of refrigerant scales, gauges with temperature clamps, and thermometers for accurate indoor/outdoor temperature readings

Matt will then elaborate on the differences in commissioning Unitary systems versus Mini Split systems: 

  • Unitary - expect insights into airflow verification, refrigerant charge validation, equipment-specific TruFlow tests, room-by-room balancing, and more 
  • Mini Split - differentiate between ducted and ductless systems, shedding light on system charge verifications, the importance of diligent record-keeping from rough-in to finish, and the nuances of temperature splits, among other key processes

This session is a part of a three-part series on how to effectively design, install and commission air source heat pumps (ASHPs) in residential homes. 

This series has been developed by and for building industry professionals (builders, designers, HVAC contractors, raters, and beyond) to better understand ASHP applications and to provide tangible design principles and construction practices that can be integrated into your building process.

Attend this 'Heat Pump Mastery' webinar series to gain field-tested recommendations from building professionals on the following critical topics:

   Mastering Design Principles

     Trainers: Bruce Manclark (Earth Advantage) & Greg Davenport (Mitsubishi)

   The Ultimate Installation Guide

     Trainers: Bruce Manclark (Earth Advantage) & Matt Ryan (Petra Heating & AC)

   The Art of Commissioning

     Trainers: Bruce Manclark, Matt Ryan, Marc Cregeur (Earth Advantage) & Mike Frey (Noyes Development)

It's imperative to highlight that cold climate ASHPs are no longer emerging equipment — they're mature technologies, ready and reliable for any climate. Their stellar reputation eliminates prior misconceptions and stands as a testament to their adaptability.

Moreover, the efficiency and effectiveness of ASHPs aligns well with advancing energy codes across the NW region and makes them ideal candidates for certifications such as ENERGY STAR and a viable pathway towards unlocking substantial 45L Tax Credits and incentives.

Join us to gain info and insights on how to select appropriate heat pump equipment according to your unique project objectives.

Note: We encourage you to also rattending the ‘45L Tax Credit: What You Need to Know’ training offered as an on-demand course as a helpful precursor to this series.

Bruce Manclark
Bruce Manclark: Bruce is a nationally recognized leader in residential consulting on energy efficiency, energy efficiency technical training, implementation of conservation programs, and quality control testing. Bruce brings his comprehensive understanding of proper HVAC system installation through more than 40 years of practical experience to help clients such as the Northwest Energy Efficiency Alliance (NEEA), Bonneville Power Administration (BPA), and Energy Trust of Oregon to develop HVAC, new homes and existing homes program strategies. In April 2016, he was inducted in the Building Performance Industry Hall of Fame recognized for his significant and lasting contributions to the building performance industry over the course of his career.

Matt Ryan
Matt Ryan: Matt is the COO and Co-Owner of Petra Heating and Air Conditioning, Inc. Matt grew up with close ties to the HVAC industry and joined the trade himself at the age of 19. In 2006 he and his wife, Sarah, started their company from their home garage in Portland with a drive to partner with high performance builders. Petra has worked with Energy Trust and Earth Advantage for well over a decade, also gaining solid partnership and respect from many leading green builders in the area over the last nearly 18 years. Today, Petra operates with 25 employees from a 6000 square foot warehouse and office in Clackamas and is committed to continuing education and development for leading HVAC energy efficiency in Oregon and SW Washington.

Mike Frey
Mike Frey: Mike is the Vice President of Noyes Development Co. He drives the vision for home construction and oversees the general operations for Noyes Development, a high-end Portland area spec builder known for high performance construction methods and Zero Energy/Zero Energy Ready homes. Mike is an advocate for better building practices and ensures Noyes homes are healthy, comfortable, durable, efficient, and sustainable. He has served as the Vice Chair and Chair of the Home Performance Council at the Home Builders Association of Metropolitan Portland, participated in the Willamette West Habitat for Humanity Construction Committee, and is a part of the EEBA Builder Benchmark Group where he collaborates with builders from across North America.

Marc Cregeur
Marc Cregeur: Marc Cregeur is a Green Building Consultant and Passive House Rater at Earth Advantage, working with their Single-Family Home Certification Green Building Program.
