Infection Control

 

This is a series of white papers covering the topic of infection control in buildings through enhanced HVAC strategies. The current world pandemic situation has brought up the question:  "What can we do to improve the air quality and reduce the possibility of disease spread in our facilities and buildings?". 

 

There are a vast array of available methods and technologies that can aid in the process of improving the air inside the occupied space and preventing infection. Air cleaning may be done as part of the HVAC system through enhanced filtration, fresh air regulation and sterilization, or by using in room devices, either permanent or temporary portable units.


Some of these technologies are time tested and proven in the medical and biotech fields. Some are promising new technologies that may prove to be effective in the long run, however, they have not been in use long enough to clearly identify their effectiveness. Some technologies are not proven to be effective at all at controlling infection agents. This series of white papers will try to separate the fact from the fiction and provide reliable guidance on how to effectively mitigate the spread of infection in buildings.

 

Schnackel Engineers can assist you with a thorough evaluation of your building to ensure you are doing everything possible to prevent the spread of viruses within your facility. Please give us a call at 1-800-581-0963 or email us at info@schnackel.com for a consultation.

 
 

Featured White Paper

 
HVAC Infection Control in Hotels  

Continuing our look into occupancy specific building types this paper examines the unique characteristics and challenges of mitigating the spread of airborne diseases in hotel facilities. Our primary objective will be to answer the question: What should I do to my hotel facility to improve the safety and comfort of my guests and employees? Read more

 


 

Enhanced HVAC Infection Control topics:

 

 
1. Methods & Technologies:  In this white paper we discuss various types of air filtration/sterilization methods and room devices that are available to improve air quality and reduce the spread of infectious disease in buildings using existing HVAC systems.
Published May 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
2. Filtration:  In this white paper, we will discuss the various performance characteristics of HVAC filters with the goal making an informed decision as to the right type of filter to use in a particular HVAC system application.
Published May 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
3. Ultraviolet Disinfection:  In this white paper we discuss the different Germicidal UV (GUV) systems currently available for commercial, industrial and residential HVAC applications. GUV is a time-tested technology that has been used in hospital, pharmaceutical and clean room applications for decades. It is proven to be effective at killing viruses, bacteria and fungual organisms, as long as those agents can be directly exposed to UV rays of sufficient power and/or duration.
Published June 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
4. Ionization:  In addition to the mechanical filtration and UV-C disinfection methods discussed in our previous white papers, there are a number of other technologies commercially available that claim to disinfect the air or improve the overall air quality. In this white paper we look at one category of those technologies - ionization based air purification systems.
Published June 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
5. Dilution Ventilation:  In our previous white papers on infection control through advanced HVAC strategies, we have focused on the removal of infectious particles from the airstream using various mechanical, photochemical or electronic means. This article will focus on the reduction of the concentration of infectious (and non-infectious) particles in the building through dilution ventilation.
Published July 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
6. Humidity: Next in our ongoing series of white papers on Enhanced HVAC Infection Control, we examine one of the most significant factors affecting the spread of disease within buildings - humidity.
Published July 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
7. Ventilation Effectiveness:   In this paper we will discuss how well we can expect the outdoor air to mix with the air in the rooms and the likelihood that any airborne contaminates in the rooms will be captured and returned to the HVAC equipment for treatment or removal.
Published August 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
8. Covered Malls:  In this white paper we will discuss the unique characteristics of the HVAC systems in covered mall buildings to see how well they can be adapted to the best recommendations and guidelines regarding indoor air quality and infection control.
Published August 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
 9. Offices: Continuing our look into occupancy specific building types this paper examines the unique characteristics and challenges of mitigating the spread of airborne diseases in office buildings. Our primary objective will be to answer the question: What should I do to my office building to improve the safety and comfort of its occupants?
Published September 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
10. Retail Stores: This paper examines the unique characteristics and challenges of mitigating the spread of airborne diseases in retail stores. Our primary objective will be to answer the question: What should I do to my store to improve the safety and comfort of my employees and customers?
Published October 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
11. Restaurants: This paper examines the unique characteristics and challenges of mitigating the spread of airborne diseases in restaurants. Our primary objective will be to answer the question: What should I do to my restaurant to improve the safety and comfort of its patrons and employees?
Published October 2020 | Authors: Gregory R. Schnackel, P.E.., Pedro Ferrer, P.E.
 
 
12. Health Clubs:  Continuing our look into occupancy specific building types, this paper examines the unique challenges of mitigating the spread of airborne diseases in health clubs. Our primary objective will be to answer the question: What should I do to my health club facility to improve the safety and comfort of its patrons and employees? Read more
