Brian Hafendorfer is a licensed professional engineer with over 20 years of experience in commercial air conditioning, industrial refrigeration, and indoor air quality. Having spent time in the commercial HVAC manufacturing world, as well as the design-build construction industry, Brian has a well-rounded background in the design, development, manufacturing and application of HVAC systems and equipment as well as the hygienic design of Food & Beverage industrial manufacturing facilities. He has a passion for sustainability and is actively engaged in creating innovative solutions for customers that exceed their expectations.
As Director of Mechanical Engineering, Brian leads teams of mechanical engineers and refrigeration engineers to develop, implement, and execute the design and construction administration phases of design-build projects. He facilitates the preparation of design proposal documents, leads the development of cost-effective solutions for major proposal offerings by partnering with engineering and architecture resources, provides accountability for design schedules and project budgets, and coordinates with project management and site management teams on the execution of projects throughout their life cycle.
Brian is an active member of ASHRAE having received the 2018 ASHRAE Chapter Service Award, the 2019 ASHRAE Distinguished Service Award and the 2021 Regional Award of Merit. He has served on multiple ASHRAE committees including SSPC 62.1 - Ventilation for Acceptable Indoor Air Quality as voting member and subcommittee chair, past chair of TC 2.9 Ultraviolet Air and Surface Treatment, and as a voting member of TC 2.3 - Gaseous Air Contaminants and Gas Contaminant Removal Equipment and TRG4.IAQP - Indoor Air Quality Procedure Development. Brian is a former treasurer for Region VII and served as the advisory panel chair for ISO TC 142 Working Group 2 - UVC technology. Within the Bluegrass Chapter, he held various chapter chair and officer positions, ultimately progressing to Chapter President.
Brian has authored numerous publications and presented on various topics including sustainability, indoor air quality, coil design and application, advanced air handling systems, humidity control, ASHRAE standards, and air cleaning and filtration.
Moisture Management in Buildings
Moisture is an essential part of life on planet Earth. However, when not properly managed it also cancause a host of problems including occupant health & safety, damage to facilities, equipment, andproducts within buildings. Learning the sources, root causes, and solution strategies can help guidedesigners and builders how to properly manage the design, installation, operation, and maintenance ofbuilding systems to prevent potential pitfalls that impact health & safety of the occupants and thebuilding and materials located within.

Refrigeration Systems vs Mechanical Systems: What’s the Difference?
The scope delineation between Refrigeration and Mechanical disciplines can be subtle yet detailed and can puzzle even the more experienced of engineers. In industrial facilities, Refrigeration generally takes over when a room sustains a temperature below 65°F down to subzero temperatures. These spaces often require hygienic design features that are ubiquitous in Food & Beverage manufacturing facilities. Specialized equipment and materials of construction are commonplace to allow for frequent hygienic wash down cycles to control microbial growth and prevent food contamination, enhance food safety, maximize shelf life and maintain food quality.
Natural refrigerants including ammonia and carbon dioxide, cascade systems, recirculated refrigeration systems in lieu of direct expansion or flooded systems, and a plethora of process equipment with direct cooling needs further expands the scope commonly presided over by the refrigeration engineer. This course covers specific differences in equipment, applications, performance and design of industrial / commercial refrigeration systems and mechanical HVAC systems. Following this course, a designer should have a deeper understanding of industrial refrigeration, and the nuanced differences of these systems from mechanical HVAC systems.
Filtration and Air Cleaning (what have we learned)
Particulate filters used in HVAC systems have been around since the early 20th century. Fire proception,HVAC system cleanliness, and building cleanliness were the original objectives for filtrationsystems. Over the ensuing years, awareness of indoor air quality and its effect building occupants hasbecome much more widespread, which has led to a better understanding of the needs for air filtrationin occupied spaces and the development of IAQ solutions to meet those needs. The COVID-19 pandemichas thrust the air cleaning and filtration industry to the forefront of the conversation as the industrybecomes more aware of the possibility of infectious aerosols. The presentation will discuss the need forair cleaning, contaminants of concern, system design, technological solutions, and vertical marketneeds.
The course will cover various airborne contaminants, their health effects, and mitigation strategiesincluding air cleaning, filtration, surface cleaning, air pressure management, and airflow movement inbuildings.
Case Study: The Reality of Carbon in the Construction Industry
Carbon emissions and sustainable designs are gaining focus around the world at an increasing rate.Regulations and standards are evolving rapidly similarly to the solutions that are available. But, so arethe reasons that we are challenged with on how to get the industry across the finish line. Reliability inthe data that we use and the facts is ever more important.
As designers, we often focus on the operational carbon emissions of the buildings that we design orwhere we work. Embodied carbon emissions, life cycle of direct and indirect emissions, and theresolution of the data that we use to invoke change in the construction industry are critical in making animpact on our sustainable future. The future belongs to all of us.
Indoor Air Quality: What You Need to Know for a Healthy Building
Managing infectious aerosols in indoor spaces can be achieved by focusing on the same 4 techniquesused to manage other contaminants in indoor spaces to maintain acceptable Indoor Air Quality.Building control strategies and direct control of contaminant sources and contaminated can impactpotential infection rates in buildings. Guidance for re-opening and operating buildings will also beaddressed.
The COVID-19 pandemic has had a significant impact on the global population. The mitigation strategiesdiscussed in this presentation are tried and true techniques to help prevent the spread of airborneinfection diseases.
