Acute Care Hospital

LSS was contracted to perform complete HVAC Systems Cleaning of five (5) systems.  The systems serviced Surgery, the Emergency Room, and Same Day / Outpatient Surgery Unit (overall 75,000 square feet of conditioned space).  The client had two primary concerns that initiated the work; (1) The overall indoor air quality and infection control risk, especially given the areas services by the five systems, and the risk of Hospital Acquired Infections (HAIs), and (2) The client had seen fluctuations with postive and negative pressure diferrentials outside the norm required by ASHRAE and The Joint Commission, and attributed some of that to airflow blockages in the HVAC System’s terminal boxes (e.g Reheats, VAVs).

How LSS Helped the Client:

  • Post cleaning the hospital contract with a Test and Balancing (TAB) Company, to address the positive and negative air flow issues. The cleaning process played an integral part in allowing the hospital recalibrate the positive and negative pressure differentials to meet ASHRAE and Joint Commission standards.
  • Air flow improved, especially from the VAVs and the Coils in the Air Handler Units, additionally the filters were not loading as quickly. Thus energy efficiency improved, and filter cost was lessened, both factors saved the client money.
  • Cleaner HVAC Systems, with source removal of contaminants, and application of an EPA microbicide helped remove contaminants from ductwork supplying air to patients in surgery and ER beds who are immunocompromised and highly susceptible to a hospital acquired infection (HAI).
