After years, businesses are beginning to reopen their facilities for the safe return of the workforce.  In preparation for the return, businesses have been turning to rigorous cleaning, hand washing and chemical disinfectants. While effective, this does not address the source of the problem…the air itself.

As we now know, airborne transmission is a huge problem for stadiums, shopping malls, and commercial buildings.  The reason for this problem centers on malfunctioning HVAC and ventilation systems that facilitate the spread of viruses and bacteria.

Pathogens Known to Live in Indoor Buildings Ventilation Systems

A professionally designed UV-C system can inactivate 99% or more of most microorganisms present in the HVAC ducts and cooling coils. According to CDC & ASHRAE the most effective way to control airborne exposures is through:

-Proper ventilation

-Updated HVAC systems

-Addition of UVC –HVAC/upper air

-Retrofitting or replacing HVAC systems

That is why for nearly a century–UVC has been used to destroy airborne and surface-bound viral and bacterial microbes (TB, SARS, MRSA, H1N1, Chicken Pox, Legionella, Flu) in hospitals, operating rooms, and medical environments.  UV-C technology is now well recognized and used outside medical locations to improve indoor air quality, biofilm control and savings in energy consumption and maintenance costs.

                                               

Reopen Buildings Safely

Although not in the code today—by 2023 UVC will be a requirement in the revised International Building Code for all new and retrofitted HVAC systems with occupancy exceeding 1 person per 15 square feet.  To open and keep our buildings open now and for the future sustainable solutions will require reliance on best industry practices, proper ventilation, UVC technology driven and oversight by facility management and engineers.

The R Group 5-Step Ventilation Safeguard Solutions

We have spent last year studying airborne pathogens & COVID-19 and have analyzed scientific studies, engineering/energy efficient approaches, and UVC prevention and disinfecting techniques. As a result, to address, mitigate and alleviate airborne pathogens we have developed our 5-Step Ventilation Safeguard Solution:

How it works

The use of highly efficient particle filtration in centralized HVAC systems reduces the airborne load of infectious particles. This strategy reduces the trans-port of infectious agents from one area to another when these areas share the same central HVAC system through supply of recirculated air. However, even the most robust HVAC system cannot control all airflows and completely prevent dissemination of an infectious aerosol or disease transmission by droplets or aerosols.

 

Depending on UV-C intensity, length of exposure, UV-lamp placement, and lamp life cycle UV-C wavelength will kill all microorganisms living on HVAC air ducts and evaporator coils. The entire ultraviolet (UV) spectrum can kill or inactivate microorganisms, but UV-C energy (in the wavelengths from 200 to 280 nm) provides the most germicidal effect, with 265 nm being the optimum wavelength.  Proper sizing and installation of a UV-C system in proximity to the cooling coil is essential for maximum performance and life cycle cost benefit.

HVAC system w/UVC eliminates:

  • Mold & biological growth
  • Unpleasant orders
  • Need for chemical coil/pan cleaning
  • Obstructive in ducts than occupied spaces

UVC on HVAC Coil:

  • Creates 8-20% energy savings
  • Provides ROI in 1-4 years
  • Restores coils & thermal efficiency
  • Increases condensation
  • Reduces fan amperage draw

Plus, UVC in HVAC:

  • Extends AUC life by 2 years
  • Creates efficient system
  • Ensures fewer service issues
  • Mitigate risk from sickness, death & disability

The design and operation of HVAC systems can affect infectious aerosol transport, but they are only one part of an infection control bundle. For a more effective solution–The R Group’s has integrated the use of UVC in HVAC systems as well as other known and tested biological, mechanical, and engineering techniques as well.

 

“There are only two established technologies to supplement mechanical ventilation—HVAC and upper air germicidal UV air disinfection. SARS-CoV-2 is highly susceptible to GUV and is the essential engineering intervention for reducing COVID-19 spread.”

The R Group has the solution

Of course, a well-conceived engineering solution is at the heart of The R Group strategic approach.  However, solutions that we offer cost money…so, we have made it part of our strategic to have access to CARES Act funds, traditional/alternative funding alternatives and federal, state and utility energy savings incentives to pay and offset costs.

Let’s talk CARES Funding and Incentives

In order to provide maximum financial support and relief due to the lingering effects of COVID Congress enacted the CARES ACT.  The CARES ACT is very extensive and complex and offers support for almost all sectors of the US Economy.  This funding has been made available at the federal, state, and local levels and to enhance and integrate seamlessly with other funding offsets as well.

 

As experts in providing energy solutions—we identify and apply available energy offsets from the federal/state government as well as from various utilities.  Our approach to utilizing CARES ACT funding is the same—we capitalize on the available sources and include those offsets in all our budget projections. We take care to incorporate any CARES ACT funding & incentives with already existing incentives in-place for energy conservation & sustainability specifically for:
