Air Filters in the Built Environment 

This 45-minute webinar is a companion to AIRAH’s Design Application (DA) manual – DA15 Air Filters. An updated version of this manual will be released in June 2019. It is part of AIRAH’s essential suite of publications for professionals working in the HVAC&R industry.

About the webinar

This webinar will introduce and provide an overview of air filters. It will also investigate why and how they act as a vital component in maintaining the health of people in a building.

In addition to a broad discussion on filter design and applications, we will look at:
  • The need for treating outdoor and indoor air
  • An air filter’s impact on occupant health
  • An overview of filter standards.
The presentation will explore the reasons for updating DA15, first published in 1998. It will detail some of the filter developments and modernised testing methodology.

Daniel McCaffrey, M.AIRAH, AFPRO Filters Australia Pty Ltd

Daniel has worked in the air filters industry for over 40 years and has been involved in the review and development of AIRAH‘s updated DA15 manual.

Updates to DA15

This DA manual has been designed to provide a complete overview of filter and air cleaner usage in HVAC&R. It begins with an examination of outdoor and indoor air contaminants and the role filters and air cleaners can play in maintaining safe and healthy indoor environments.

DA15 first focuses on particulate air filters; the principles and fundamentals of filter operation; classification; and performance. The manual then addresses the issues around implementing filters in air distribution systems, including system design and optimisation; filter selection and specification; system installation; and commissioning. It continues through to handover, operation, and maintenance.

The publication also examines other air cleaning technologies and devices, including a comprehensive consideration of gas phase air cleaners (GPAC) and ultraviolet germicidal irradiation (UVGI) technologies and applications.

This is an informative series of three short webinars that will provide you with the knowledge to identify and manage the transition away from HCFCs and HFCs.
The Montreal Protocol sets out a mandatory timeline for the phase out of ozone-depleting substances including hydrocholorflurocarbons (HCFCs), such as R22 and the phase-down of hydroflurocarbons (HFCs). Strict regulations, standards and procedures must be followed when handling refrigerants and air-conditioning equipment must comply with relevant Electrical Safety Standards.

This webinar provides an overview of the smart grid particularly as it relates to buildings and their systems.

The smart grid is coming; and in the future buildings will be interacting even more with electricity utilities. Communication will be in both directions, with the utility working to balance grid supply and demand using methods such as signalling requests for demand-response measures and real-time price adjustments. This is a new and evolving field, and while there are some differences in the way a smart grid might function in various regions of the world, there are some common factors as well.
