As Environmental Health and Safety Professionals, creating healthy environments is at the forefront of our minds as we navigate this new terrain as a direct result  of COVID-19.  As a mechanical contractor that serves clients throughout the United States, our clients looked to us to provide them with the best HVAC and plumbing solutions for their facilities, including solutions for building readiness to assist in creating healthy spaces for occupants, tenants, and their workforce. We did this by creating  a facility plan for mitigating virus  risk and increasing building safety. This is a three-phase approach starting with an audit to determine the building’s current readiness state, a look at potential upgrades that will help mitigate the risk of viral infections, and lastly, evaluate the efficiency of the filtration system to assure the system is operating at peek filtration optimization.

In the hierarchy of controls elimination, isolation, and engineering controls are the three most effective approaches to mitigating hazards. Our Audit/Update/Optimize approach follows these principles in creating a safer, healthier building for all.



How ready is your building for the latest healthy building solutions? What are you doing right, and what can you build on? What strategies can you implement to improve indoor air quality?


Evaluate to assure your facility is running at optimal levels. Evaluate current HVAC and plumbing systems to identify needed repairs, adjustments, or  upgrades to enhance efficiency and operation.


Audit and adjust the amount of fresh air  being introduced into your facility to achieve the  ASHRAE and CDC recommended guideline.


Our professionally licensed engineers are here to help. Based on  our findings from the  building readiness and existing system design audits, we are  able to provide engineered solutions and permit plans for any upgrade(s) that  improve your facility.



Bi-polar ionization is an emerging technology that can be installed in an HVAC unit’s air stream. Airborne particles are  charged by these ions causing them to cluster, which improves filter effectiveness and overall air  quality.

  1. Install a commercial quality, bi-polar ionization system into your existing HVAC system.
  2. The bi-polar ionization system introduces odorless, non-harmful ions into the air stream using the airflow of your existing ventilation system.
  3. Airborne particles are charged by these ions causing them to cluster, which improves filter effectiveness and overall air quality.
  4. These larger, harmless particles are now filterable and can be captured in air filter, providing cleaner air.


Ultraviolet light  has  a long-standing reputation of creating healthy spaces. These lights can  be  installed in an  HVAC unit’s air  stream to mitigate viruses and bacteria while improving overall coil/ condensate pan cleanliness and efficiency.

Although the technology is relatively simple, ultraviolet light remains one of the most cost-effective solutions for maintaining a healthy indoor environment. These UV-C lights on your HVAC unit’s air stream deactivate viruses and bacteria while improving overall system efficiency


Murphy specializes in designing and installing building automation systems that reduce the risk of viral transmission via surfaces with touchless technology. This decreases the opportunities for  surface transmission by installing touchless fixtures and bottle fillers throughout your facility. Not only  do  these changes provide healthy environments, but  they  also  serve as visual indicators of owner and property management safety initiatives.



Determine the highest filter efficiency that  the  equipment in your building can  support.  Evaluate the  capacity and determine what will  work best  with your equipment without bogging down the efficiency.

Develop a filter change strategy that  will  help optimize the filter effectiveness of your investment.


In today’s climate,  you should  be more prepared  than ever to have  the proper precautions in place for your facility. You probably  have  heard a lot about updating  and improving your air quality, but did you know your water quality could be impacted as well? Have your plumbing system and water lines been flushed to assure a clean water system?

Legionnaires’ Disease is a serious type of pneumonia caused by bacteria, called Legionella, that live in water.  Legionella can make  people sick when they inhale contaminated water from building water systems that are not adequately maintained.   Unfortunately, Legionnaires’ Disease is on the rise in the United States.

Your building may need a water management program to reduce the risk for Legionnaires’ Disease associated with your building water system and devices.  This water management program should  identify areas or devices in your building where Legionella might grow or spread  to people so you can create  a plan to reduce that risk.


Look for opportunities to utilize your existing Building Maintenance System, to develop a controls plan to improve the  health of your building, creating a cleaner environment.  Identify controls upgrades to optimize and improve your system.

There are many additional steps you can take to make your buildings safer, but these are just some of the many mechanical solutions that many overlook.
