Mercy Hospital Northwest Arkansas — Inpatient Bed Tower + Expansion + Hospital Renovation*
location | rogers, ar
sq. footage | 380,000
Mercy Hospital Northwest Arkansas is located in Rogers, Arkansas which is one of the fasted growing MSA’s in the country. Due to the explosive population growth in the region, the original 200 bed Hospital, which opened in 2008, was experiencing bed shortages, and other capacity stresses by early 2013. That year, in the role of Planner, Paul Sabal prepared a Strategic Facility Masterplan for Hospital leadership which clearly identified that all nursing units and the ED would be at capacity by 2015, and all D&T and support service departments would be at capacity by 2019. In 2015 Mercy Hospital NWA re-engaged Paul to prepare a phased expansion Master Plan ofthe Rogers campus. This time, in the role of Principal-in-Charge and Planner, Paul recognized that the key factors for the successful outcome of the project to be:
+ Optimize patient experience and staff/user efficiencies
+ Develop a fastest path to additional bed capacity
+ Relocate the Hospital main entry for greater visibility
+ Conform the appearance of the existing facility to current Mercy Brand standards
+ Locate the expansion to maximize new construction SF, minimize renovation SF
+ Locate the expansion to provide the best adjacency for expansion of the support and D&T departments on the lower floors
+ Locate the expansion to minimize impact on existing operations
+ Locate the expansion to minimize impact on the existing ED
+ Expand surface parking to address future parking need and compensate for loss of parking due to new construction
After testing many options with leadership, Paul chose a solution which places a 7-story bed tower to the West of the existing Hospital. This location provides space directly adjacent to support service departments on the 1st floor, Imaging and Diagnostics on the 2nd floor and Surgery on the 3rd floor for expansion. Floors 4 through 7 connect directly to existing Nursing units and are serviced with dedicated public and service elevators. On the North elevation, the relocated Main Hospital Entry gives patients easy access to all destinations through a 2-story gallery element that provides welcome, admitting, pre-admit testing, and waiting spaces. The entire exterior of the existing 2008 structure is being reimaged using innovative masonry staining techniques to match the requirements of Mercy’s exterior Brand standards.

Ledger
location | bentonville, ar
Energy Conservations Measures / Envelope Glazing Systems: Ledger is a unique seven-story “bike-able” building located in NW Arkansas. (https://ledgerbentonville.com/) Our team served as the primary engineering firm from the initial ground breaking through to full occupancy. We provided comprehensive energy modeling services to ensure both strict code compliance and informed envelope selection. Given the building’s full-glazing exterior, selecting the right glass system was critical. By leveraging energy model reports, we narrowed the glazing options down to two finalists, helping the client visualize the long-term performance differences. This data-driven approach allowed the client to make a confident, final selection that aligned with the building’s aesthetic and efficiency goals.

Services | Investment Grade Audit, Turnkey Energy Savings Performance Contracting, Commissioning, Retro-Commissioning, Energy Modeling, Measurement & Verification, and Ongoing Commissioning
In fall of 2018, the University of Arkansas interviewed and selected Entegrity to implement an Energy Performance Contracting program and reduce their expenses and carbon emissions.
Entegrity’s campus-wide assessment justified a comprehensive energy and operational efficiency project to generate enough savings over a 10-year term to exceed the cost of implementation. The University’s project covered over 5,000,000 SF and nearly 100 unique facilities and included:
+ 3 MW solar energy
+ LED lighting upgrades for 66,436 fixtures
+ Retro-commissioning of 35 buildings
+ HVAC equipment replacements
+ Fault detection diagnostics (FDD)
+ Envelope improvements
+ Telecommunications billing changes
Combined, the measures created more than $1,500,000 in annual guaranteed savings for the University. Financial leverage created through energy savings also allowed non-energy saving measures such as implementing window replacements, sustainability education programming, and small pilot programs to test the potential of creating even greater future savings.
