Facility Square Footage: ~85,950 sq.ft. | Location: Shreveport, LA
- The project required the installation of seven new variable air volume (VAV) air handling units (AHU) of varying capacities
- As part of the expansion, new cooling capacity was required. New chilled water piping of sufficient size was installed to accommodate the hydronic flow rates required by the new system. This new piping was tied into the existing central plant already in operation prior to this expansion
- Variable air volume boxes are designed and installed throughout the facility to provide the required levels of airflow
- All air handling units have chilled and heating water coils. These coils are designed to work in conjunction with one another to create the environmental conditions in the operating rooms required by code
- Operating rooms have specific and precise environmental conditions that must be maintained in order to ensure the safety of patients during surgery. The required temperature and humidity levels cannot be achieved without specific mechanical equipment designed by an experienced mechanical engineer well-versed in the design of mechanical systems in hospitals
- Exhaust fans were designed as part of the code-required smoke control plan that contains and controls smoke in the event of a fire emergency
- The electrical system serving the operating room and ICU areas of the hospital required equivalent knowledge of and attention to code in its design. Sufficient generator capacity, capable of coming online within the time constraints outlined by code, was designed to serve the operating room and ICU expansion in the event of a power outage
Room Pressure Monitoring
Positive pressure in an operating room must be maintained within very specific code-required limits. Proper positive pressurization of an operating room begins on day one of the design when the design professional sits down and begins specifying each component of the mechanical system. The correct reading on the Room Pressure Monitor (pictured at left) is more than just a reading on a screen. It is the result of extensive coordination between the design and construction professionals to ensure each piece of the mechanical system has been correctly chosen and installed.
Laminar Flow In Operating Rooms
Laminar flow in operating rooms is important for the safety of patients. A specific arrangement of supply air diffusers and return air grilles must be designed to work together to create the laminar airflow patterns that are required to meet the desired safety objectives.
