PHOENIX—Valleywise Health opened its new 673,000-square-foot, 10-story medical center to patients on June 13, replacing the legacy hospital that has served the community for more than 50 years.

After years of construction and months of planning, Valleywise Health staff is moving more than 200 patients from the existing tower to the new state-of-the-art facility. Each will have an individual patient room designed for both function and comfort, featuring private bathrooms and sleeper sofa/recliners.

The new Valleywise Health Medical Center has been decades in the making,” said Steve Purves, Valleywise Health President and CEO. “We’re thrilled to open it to the community today and grateful for all the support we’ve received since our funding measure was passed in 2014.”

Within the new hospital, the Diane & Bruce Halle Arizona Burn Center occupies an entire floor, boasting three dedicated trauma bays, a dedicated pediatric wing, a large physical occupational therapy room, a hyperbaric chamber and space for research and teaching.

“It’s hard to overstate the value of having a world-class public teaching hospital right here in this neighborhood,” shared Phoenix Mayor, Kate Gallego. “Valleywise Health has been a fixture in our community for over 100 years, and I think it’s safe to say the $935 million commitment to bring this new facility to fruition couldn’t have been put to better use.”

Also open to patients today, the new 34,550-square-foot emergency department includes three trauma bays, 88 private rooms, a dedicated pediatric space, indoor and rooftop decontamination showers as well as ground floor and rooftop helipads. By 2026, Valleywise Health anticipates nearly 86,000 emergency visits annually.

“The new hospital was designed to put patients first,” Purves added. “It incorporates both the latest technology and design improvements that will ensure comfort for both patients and their families. Beyond that, it makes unprecedented resources available to the hundreds of residents that Valleywise Health doctors train every year.”

Cuningham Group served as architect and Kitchell as the general contractor. The new medical center will host a variety of specialties including cardiology, trauma and emergency, maternity, NICU, oncology, pharmacy, radiology and more. With ten operating rooms, two interventional radiology areas, two cardiac catheterization labs and two helipads, the new site represents significant growth over the legacy site that opened in 1971.

PHOENIX—As Valleywise Health moves toward the opening of its new 673,000-square-foot, 10-story hospital, leaders have announced that construction is 95% completed. Exteriors and infrastructure are finished, including electrical, plumbing and medical gasses. At this point the heavy focus and efforts are on testing systems, final inspections, touch-up and clean-up.

“It’s beyond exciting to be only months away from opening our new Valleywise Health Medical Center,” said Steve Purves, Valleywise Health President and CEO. “This state-of-the-art hospital will serve to further our mission of providing exceptional care without exception, every patient, every time.”

With Cuningham Group serving as architect and Kitchell as general contractor, the new Valleywise Health Medical Center will open to patients on April 11, 2024, heralding a new era of care for Arizona’s only public teaching hospital and safety net system of care.

“This new hospital is far more than a building, it’s the healthy future of our community,” said Dr. Michael White, Chief Clinical Officer. “It will enable us to better provide safe, quality care and train a new generation of health care providers in a healing, patient-centric environment.”

The new site will house the 75,000-square-foot Diane & Bruce Halle Arizona Burn Center, and specialties including cardiology, trauma and emergency, maternity, NICU, oncology, pharmacy, radiology and more. With ten operating rooms, two interventional radiology areas, two cardiac catheterization labs and two helipads, the new site represents significant growth over the legacy hospital that opened in 1971.

Further enhancing the patient experience, each of the 233 individual patient rooms, unlike the old facility, will have private bathrooms and sleeper sofa/recliners to support families. The state-of-the-art kitchen will provide more options for patients and visitors alike.

“Our new hospital was designed to put patients first,” White added. “It incorporates the significant technological advancements made in health care and the additional space will ensure we can provide the best care possible.”

This milestone comes on the heels of the opening of the Virginia G. Piper Charitable Trust Pavilion. The Piper Pavilion serves as a new learning and teaching hub, with clinical education housed on three floors of the six-story facility, in addition to administrative services and community meeting space for up to 300 people.

Valleywise Health isn’t just making changes at its Roosevelt site – the provider has opened five community health centers in recent years to better serve patients across the Valley. Each center provides access to primary and pediatric care, integrated behavioral health services and an on-site pharmacy.

LA JOLLA, Calif. — The new Jacobs Medical Center at UC San Diego Health in La Jolla opened on Nov. 20, 2016. Construction began in 2012, and the center was named in recognition of a $75 million gift from the Joan and Irwin Jacobs family. The 245-bed new medical center brings cutting-edge technology for cancer treatment and other specialty care.

The 509,500-square-foot 10-story facility had a budget of $943 million. Architecture and interior design were provided as a collaboration between the Yazdani Studio of Cannon Design in Los Angeles and Cannon Design’s Los Angeles Office. The general contractor was Kitchell Contractors out of their San Diego and Phoenix, Ariz. offices.

The Jacobs Medical Center will contribute to meet the healthcare needs of San Diego County — San Diego is California’s second-most populated city, with 3.3 million residents, and 17 percent fewer acute-care beds per 100,000 residents compared to the statewide average, according to a statement. The medical center includes three specialty centers: one for women and infants, a cancer center, and an advanced surgery center.

The design team created over 60 design concepts with a wide range of configurations and relationships to other buildings on the campus throughout the process, according to William D. Hamilton, AIA, principal at Cannon Design. “The scheme continually changed over time, with the footprint and building envelope being driven by the number of beds per unit, and the number of rooms with windows and daylight defining the floorplate.”

The surgical center has 14 operating rooms with an advanced surgical suite of four operating rooms. The center also has an MRI and 64-slice CT scanner for real-time imaging. The medical center houses a cancer center with 108 beds in addition to its 245 acute-care beds. There is an entire floor in the cancer center dedicated to blood and bone marrow transplant surgery and recovery. One of the state-of-the-art features of the cancer center is a floor that receives specially filtered air to help protect patients with compromised immune systems, according to a statement.

The hospital also houses an intensive-care unit with 36 beds in family-friendly rooms, 36 postpartum beds and a 52-room, neonatal intensive-care unit. Each room in the birth center has its own built-in birthing tub. There is even a “serenity room” in the hospital, beautifully designed with wooden curved benches and walls that promote relaxation through their design.

The Jacobs Medical Center is a triangular building, with a unique curvilinear design, and is connected by footbridges to UCSD’s Thornton Hospital on the La Jolla campus. “The geometry creates a subtle continuous flowing curve of the exterior — a dynamic form that changes as one passes around the building’s perimeter,” said Hamilton. Most rooms at the hospital have floor-to-ceiling windows to maximize natural light with panoramic views of San Diego, and gardens outside the facility designed to promote healing.

There are dedicated family areas with lounges and kitchenettes on each inpatient floor, and outdoor terraces and courtyards. Every floor and patient room is decorated with the 150-piece art collection donated by philanthropist Joan Jacobs that includes paintings, photographs and sculptures by renowned artists. There is a rooftop helicopter landing pad, and the building has a low-carbon footprint that meets the requirements for LEED-Silver certification.

Some LEED-Silver features of the hospital include a drought-tolerant plantings and sprawling green space at the ground level and at the patient level via raised gardens, according to Hamilton. The overall curvilinear form of the hospital maximizes daylight and minimizes solar gain and glare. Fritted glass serves as buffer to the southern sunlight, minimizing the building’s cooling output. The building is in close proximity to bus and light-rail transit, provides designated parking for low-emitting vehicles, and includes bike storage and changing rooms to encourage alternative transportation.

The Joint Commissions Environment of Care standard associated with emergency power systems was among the top 10 standards cited for noncompliance during critical-access hospital surveys in the first half of 2011. In order to enhance the performance, capacity and reliability of emergency standby power systems, new recommendations encourage health care organizations to go beyond basic code-driven requirements.

When the power goes out, having a backup power system is vital for patient safety and for preventing loss of life. Beyond electrical codes, numerous organizations are involved in setting standards and overseeing patient safety in health care facilities. These groups include the National Fire Prevention Association (NFPA), the Joint Commission (formerly known as JCAHO, the Joint Commission on Accreditation of Healthcare Organizations), and the American Society of Healthcare Engineers (ASHE). Some states also have their own standards organization; Californias Office of Statewide Health Planning and Development (OSHPD) is one example.

While the scope of these organizations oversight ranges widely, they all have specific rules and recommendations for emergency standby power systems. Rules specify that emergency standby power is vital for patients in operating rooms, obstetrical delivery rooms, nurseries and urgent care areas. It is also critical for life-support systems, blood, bone and tissue storage systems, medical air compressors and vacuum systems, as well as communication systems, elevators and egress lighting.

Recently, the Joint Commission issued a top 10 list of the most frequently cited standards in surveys for its health care accreditation program. This list included observed deficiencies in emergency standby power systems in a large percentage of the health care facilities surveyed. Deficiencies included both equipment problems and procedural problems having to do with planning, testing, maintenance and documentation of standby power systems.

Events Focus Attention on Deficiencies
The majority of utility outages in North America tend to be infrequent and of short duration, and many business owners and homeowners are also able to protect objects in their property such as their electronic devices thanks to companies like barnettelectrical.com/residential-services/surge-protection/, so they’re not affected majorly. However, in the past decade there have been a number of region-wide events that severely taxed existing emergency standby power systems or exposed a significant system design flaw that led to catastrophic failure of the backup power system. Examples include the Houston floods of 2001, the 2003 utility blackouts in the Northeast U.S., and the 2005 hurricanes in Florida, Louisiana and Mississippi.

These and more recent disasters have repeatedly shown that a small proportion of emergency power systems may fail when most needed, due to inadequate system design or poor maintenance procedures. Some power systems failed due to design, such as systems housed in the basement or on the main floor of hospitals located in a flood zone. Others failed to start due to fuel contamination or weak starting batteries the results of poor maintenance. Still others ran out of fuel before utility power was restored due to poor contingency planning.

The Joint Commission reported that these incidents ranged from single unit failures to entire large medical centers and each was associated with one or more patient deaths.iii Other natural disasters in recent years include events in Fukushima, Japan and Washington, D.C., where seismic activity renewed awareness of the International Building Code (IBC) for emergency standby generator systems and related equipment.

Joint Commission Recommendations
In the wake of the incidents cited above, the Joint Commission issued a list of recommendations that went beyond the current NFPA testing requirements and electrical codes. Aimed at reducing emergency standby power system failures, those additional recommendations are outlined below.

1. Perform a gap analysis on the emergency power system that compares critical equipment and systems needed in the event of an extended outage with the equipment and systems actually connected to the emergency power system.

The emphasis here is on preparing for extended outages and verifying that the standby power system is actually connected to and powering the facilitys most critical loads. This is especially important if the health care facility is older and may have several independent emergency standby power systems located in different areas that were added as the facility grew. At some point, it is prudent to consolidate all of the emergency standby power into one modern system and eliminate functioning but obsolete equipment.

In new facilities or during major expansions, it is also a good idea to evaluate whether to add enough generating capacity to supply noncritical loads in addition to critical loads required for life-safety purposes. Often, loads that are considered noncritical in short power outages such as HVAC become critical loads when the focus is on preparing for an extended outage.

Overall, the trend in system design is for the emergency standby power system to supply the total peak load of the facility, not only for life safety, patient comfort and convenience, but also for business continuity. Planning for extended outages also focuses attention on having adequate onsite fuel storage and a procedure for resupply. NFPA 110, Paragraph 5.1.2 requires many mission-critical hospitals (specifically, those with an IBC seismic design Equipment Importance Factor of 1.5) to have 96 hours of fuel storage on-site.

2. Maintain a complete labeled inventory of all emergency power systems and the loads they serve.

This recommendation is part of a much larger requirement for complete documentation of the power system(s), including records of testing dates, duration, loads and notes on any performance issues. Modern digital generator sets have numerous built-in functions that facilitate data collection and recording that greatly ease compliance with this guideline. Also, keeping track of how loads grow and change over time can help ensure that the standby power system has adequate capacity to supply them.

3. Provide competent training and testing of all operators responsible for operating or maintaining the emergency power system.

A standby power system is only as reliable as the people responsible for operating and maintaining it. In addition to providing operator training and testing, large health care facilities should consider engaging the generator set distributor or other service organization to perform the periodic maintenance on the standby power units. Not only does this ensure that the maintenance is done in accordance with the manufacturers recommendations, it makes sure that it is performed on a regular schedule and fully documented. Generator set manufacturers and their distributors can also assist with operator training.

It should also be emphasized that the importance of maintenance extends to the entire power distribution system, not just the engine generator. For example, switchgear needs to be opened for cleaning, calibration, thermal scanning and other critical preventative maintenance as required by industry codes, standards and generally accepted practices. It is also important for all departments to understand the difference between preventative vs predictive maintenance in order to adhere to health and safety regulations.

4. Regularly test diesel fuel in the storage tank and replace fuel not consumed before the end of its storage life.

Diesel fuel has a limited shelf life, and one of the reasons for regular generator set exercise is to consume and replenish fuel before it becomes old and affects generator set starting or operation.

The recommendation for regular testing of fuel quality is even more important in light of rules to keep 96 hours of fuel onsite for extended outages. With larger-capacity fuel tanks on-site, it is unlikely that regular generator set exercise will consume all the stored fuel in a single year. To ensure reliable starting and prevent fuel filters from clogging, fuel supplies need to be replenished with fresh fuel and fuel quality needs to be tested regularly. Also, as more states mandate bio-content in some fuels, it is even more critical that the fuel supply has a robust maintenance program.

5. Provide for communication between the operators of the emergency power system and the organizations management and clinical leaders.

Utility outages occur without warning and usually at the worst possible time. It is, therefore, critical to have direct communication channels between the power system operators and management and clinical leaders. State-of-the-art standby power systems with digital control systems offer expanded communication with multiple parties and help facilitate coordination during outages. Remote-monitoring capabilities allow both management and clinicians to know, in real time, the status of the standby power system.

This recommendation for health care clinicians is based on the remote possibility that the standby power system may fail to start or start and then fail to run reliably. In other words, there needs to be a plan in place for protecting patient safety in the absolute worst-case scenario where there might be no utility power and no standby power.

Improving Reliability is a Central Theme
The overall goal of the Joint Commissions recommendations is to help maximize the reliability of the emergency standby power system. To a great extent, reliability can be designed into generator sets, transfer switches, switchgear and control systems to increase the likelihood that they function as intended. One major area that affects reliability is the IBC certification for systems designated with an Equipment Importance Factor of 1.5.

Manufacturers are working to certify their equipment through robust designs, finite element analysis, and actual shaker-table testing to ensure that equipment not only withstands a seismic event, but will function immediately after to supply critical loads.

Other factors in reliability are maintenance, testing and support all human activities that must be carried out as part of an overall plan to make sure the system works as intended. Simple design enhancements such as scanning portals (peepholes) to allow thermal scanning of critical power distribution equipment without opening cabinets, can make tasks easier while gathering data under real-world conditions. Such design enhancements eliminate safety concerns that would have limited this kind of preventative maintenance in the past.

For health care facilities that face life-safety risks if their standby power system fails, it is often prudent to invest more in the equipment to attain the highest possible measure of reliability. In multiple-generator systems, having at least one redundant generator also enables periodic equipment maintenance to be carried out without affecting the availability or capacity of the standby power system.
After determining what level of reliability may be acceptable and affordable, an organization must turn to the selection of equipment and suppliers.

Selecting Reliable Equipment
While usually out of the scope of the health care facilities managers, the selection of the specific equipment used in a health care facilitys standby power system can have a major impact on overall costs, reliability and functionality. For the highest reliability, look for generator sets with engines that have some measure of reserve horsepower capacity at the alternators nameplate kW rating and a low brake mean effective pressure (BMEP). Engines with larger cylinder displacement and lower BMEP have a greater ability to accept load without an undue drop in output voltage and frequency. Engine manufacturers vary in their approach to this issue. Therefore, when one-step load acceptance is called for in life-safety and mission-critical applications, select a manufacturer that can provide a generator-drive engine with the highest cylinder displacement and lowest BMEP relative to nameplate kW rating.

Appropriately sizing generator sets for the specific application has a major impact on power system reliability. Some generator sets that are required to pick up a load equal or close to their nameplate rating may not perform as intended. While the generator set may start and run, it may not be able to assume the facility load in one step as required by NFPA 110, or it may take longer than the required 10 seconds for life-safety applications. Unless all critical loads are properly supplied within the 10 seconds as required by NFPA 110, the standby power system cannot be considered to be suitable for life-safety applications. Some manufacturers offer to demonstrate this capability in their factory test bays; witness testing of a system prior to installation is an excellent way to prove load acceptance performance. At a minimum, measuring performance with a power quality analyzer will verify that equipment is appropriate for use in these applications.

Maintenance and Testing
Once a power system has been properly designed and commissioned, the most important factor in its long-term reliability is regular maintenance and system exercise. Preventive maintenance of generator sets should include the following operations:
inspections
oil changes
cooling system service
fuel system service
testing starting batteries
regular engine exercise under load

Like regular maintenance, periodic testing is required by code in all health care applications. It is common for health care facilities to perform regular generator set testing during off-peak times when loads are at their lowest.

While this practice prevents the possibility of serious interruptions to large and/or critical loads, it does not adequately test the generator set under worst-case conditions. When operated with the actual building load, the entire power system can be testedincluding the automatic transfer switches and switchgear. It is very important that the engine be loaded to at least 30 percent of its nameplate capacity so that it can reach operating temperature during tests and drive off any accumulated moisture.

Another factor that makes testing under higher loads important is the growing use of specific types of diesel exhaust aftertreatment, namely diesel particulate filters (DPF). In order for the engine exhaust to reach DPF regeneration temperatures, generators need to have test runs on even higher loads than the 30 percent minimum.

At least once very 36 months, all health care facilities are required to exercise the power system under the actual facility load and full-emergency conditions for at least four hours to verify that the system will start, run and accept the rated load.

Conclusion
All health care facilities are required by local and national electrical codes to have emergency standby power for supplying power to building loads critical for life safety and building egress. In addition to those basic requirements, the Joint Commission has developed recommendations that encourage healthcare facilities to go beyond basic code requirements whenever possible. These recommendations encourage better power system planning, better operator training, more detailed equipment record keeping, and proper generator set exercise and maintenance in an effort to maximize power system reliability and patient safety.
