Bernhard TME provided mechanical, electrical, plumbing, fire protection, and structural engineering design and CMMS readiness services for a new Arkansas Children’s Hospital facility in Springdale, Arkansas. The new campus provides expanded pediatric services to patients in Northwest Arkansas. The 230,000 square foot hospital is designed as a state-of-the-art facility in terms of both the healthcare services it provides and its energy efficient design. The facility houses 24 inpatient beds, five operating rooms, an emergency care department, clinical space, and a helipad and refueling station.
The design includes a new central energy plant with the latest energy efficiency technologies and equipment. The plant features a heat pump chiller, three high efficiency chillers, three non-condensing heating water boilers, and on-site emergency self-generation. Energy recovery air handling units are used to pre-treat the outside air, and the air handling unit serving the operating rooms includes a desiccant wheel to control humidity. The facility is equipped with DDC controls, occupied/unoccupied sensors, and LED lighting throughout the building.
In addition to MEPFP and structural design, Bernhard TME provided comprehensive building controls design. The controls design uses advanced control strategies, including single loop control and cascading loops, to ensure energy efficient operation. For example, the air handling unit serving the operating rooms is controlled with occupied/unoccupied modes for temperature setpoints and air changes per hour. By reducing the air changes per hour to the required code minimum, the hospital is able to save energy without significantly altering the temperature.
Arkansas Children’s Hospital Northwest is the first hospital in the nation to utilize Autodesk BIM 360 as its Computerized Maintenance Management System (CMMS). This innovation software provides access to building models, construction documents, operations and maintenance manuals, preventative maintenance tasks, scheduled maintenance plans, and asset information. A key feature of the CMMS is the mobile access to this information. A typical operations and maintenance employee spends on average 1.5 hours per day walking from work site to shop gathering information. At Arkansas Children’s Hospital Northwest, technicians use smart phones and tablets connected to the CMMS to access relevant information as they are working within the facility. This allows for efficient and streamlined operations and maintenance.
Arkansas Children’s Hospital Northwest opened in January 2018. Bernhard TME is providing measurement and verification and energy support services to assist facility maintenance staff during the first year of operations.
