We are thrilled to announced that our Strategic Energy and Maintenance Program with St. Catherine Hospital in Garden City, Kansas received a Top Project of the Year Award in the Energy Manager Today Product & Project Awards. The project was recognized for excellence in improving environmental and energy management while increasing the bottom line.

One judge said of the award win, “This project allowed the facility to become compliant with regulations, saved money and allowed the facility to operate while meeting critical care conditions for the hospital.  It is impressive that the hospital undertook such a large-scale project to really look at improving the internal environment while also minimizing the effects upon the external environment.  Hospitals are not typically known for implementing green projects.  St. Catherine should be commended for being a leader in making improvements that will help not only their patients, but also our planet.”

Another added, “This was a great application of a building maintenance intelligence system to help with critical infrastructure, like a hospital, improve energy efficiency management without needing to spend significant capital to upgrade the facility’s central power plant. It’s a great model for other older facilities to follow.”

Scores were determined by a panel of independent judges headed by Peter Bussey of LNS Research and also including judges from:  Ball Aerospace, Best Buy, Black Ink Consulting, BSI Group, CandA, Caesars, Consultant Ben Larkey, Harbec, Kellogg, LNS Research, Marriott, Miller Coors,Nike, Novartis, Sears Holdings Corporation, Strategic Sustainable Consulting, Sustridge, Tesla,  Wellborn Cabinet, and Vincit Group.

With rapid advancements and a continuous rate of change in the field, sustainability and energy professionals have the daunting task of choosing products to help their companies increase energy, environmental, and sustainability performance. The Environmental Leader and Energy Manager Today Product & Project Awards give companies a solid base of products, vetted by experts, from which to choose, as well as a variety of successful projects to illustrate how sustainability and energy management is helping companies improve.

“With a highly respected (and critical) judging panel and a strict set of judging criteria, entrants faced an extremely high bar for the level of product or project to qualify for an award,” says Tim Hermes, publisher of Environmental Leader parent company, Business Sector Media. “Those who entered needed to bring their A-game to get even a sniff of award-nirvana. And they delivered.”

About the award-winning project: 

St. Catherine Hospital partnered with Performance Solutions to address temperature and humidity compliance issues in critical care areas, decrease energy costs and save time responding to issues. PS conducted a detailed condition assessment and identified improvements to ensure the building systems were working efficiently. To solve issues in critical care areas, a central plant and building analysis discovered an underperforming design and recent modification that caused insufficient flow to parts of the hospital. Piping modifications, equipment repairs, and new building technologies optimized chiller plant and surgical suites operations. The improvements resulted in regulatory compliance, capital cost avoidance, chiller plant and critical care optimizations, and confidence in chiller capacity keeping redundancy. To improve hospital data analytics, St. Catherine’s implemented the PS Building Intelligence Program (BIP). Maintenance staff monitors, analyzes, and runs reports in real time, enabling staff to make informed facility operations decisions and improve service quality.

Using the facility systems and data already in place, we conducted a gap analysis and comprehensive facility assessment. Armed with information, St. Catherine and Performance Solutions assessed the root cause of immediate, budget draining, facility issues and fixed them while addressing waste and consumption. We provided a complete inventory and prioritized plan to improve facility conditions and a best-practices ongoing maintenance plan. The staff trained on efficient operations strategies and in using the Building Intelligence Platform (BIP), a platform that overlays all facility automation systems to track real-time performance data. A financial model was prepared that focused on reducing existing costs. This resulted in a budget neutral program for the hospital after facility improvements were implemented.

Performance Solutions continues to track program results with real-time monitoring and regular report findings for future cost-saving opportunities and to identify facility issues before they arise, creating a more proactive approach to energy management.

In this critical 132 bed hospital, the successful Strategic Energy and Maintenance Program saved the hospital $199,800 in the first year and $1 million in cost-avoidance by avoiding the expansion of their central plant. The hospital’s key challenges of maintaining proper temperature and humidity in critical care areas, reducing energy cost and deferred maintenance, and improving building technologies were fulfilled. They now have the tools to monitor these areas and proactively eradicate problems before they occur while utilizing the BIP to its full potential- tracking trends and utility bill data to identify future projects.

Three years after implementation, the projected savings continue to be on track, exceeding projections. In fact, the hospital submitted for an Energy Star certification. The program’s success is boosting the utilities budget, making it possible to prepare for future facility upgrades and enabling the staff to focus on what matters most, the patient.

Many firms told St. Catherine’s expansion of their central plant to address the regulatory challenges was a necessity. We partnered with hospital staff to take data measurements on real-time system operations. Upon determining the plant should support the load requirement, the teams focused on optimizing the plant rather than trying to sell hospital equipment.

After repairing existing equipment, upgrading the controls system to enable more data and visibility, and setting KPI’s, the system is running effectively. It is running at 1/3 the previous flow and the maintenance team has moved from reactive to a proactive maintenance philosophy. The nurses in critical care areas were provided dashboards that show real-time performance. They can quickly check compliance levels and notify staff of any issue.

These tailored solutions go much farther than traditional performance improvement. The team created a low-cost operations strategy that paid for itself in cost-avoidance and continues to perform well. Learn more

Underfloor Technology, or Underfloor Air Distribution (UAD/UFAD), is a method of delivering space conditioning in offices and other commercial buildings. It uses open space between a structural concrete slab and the underside of a raised access floor system to deliver conditioned air directly into an occupied zone of a building. The air is delivered through a variety of supply outlets located at floor or desk level. This method of heating and cooling is quickly growing in popularity due to its potential advantages including improved thermal comfort, increased indoor air quality, and energy use reduction.

Improved Thermal Comfort
This system gives individual users control over their local thermal environment compared to traditional systems. Because ventiliation accessibility, individual comfort preferences can be accommodated. Research evidence shows that occupant satisfaction and productivity can be increased by giving individuals greater control over their local environment. Additionally, UFAD introduces supply air at a higher temperature than overhead systems, reducing the likelihood of cold sensation.

Increased Indoor Air Quality
Three items affect the increased indoor air quality experienced by UFAD users- increased ventilation effectiveness, removal of pollutants out of the breathing zone, and the ability to effectively maintain floor plenums. Ventilation effectiveness is due to the proximity of diffusers to an individual’s breathing zone. The overall floor-to-ceiling air flow pattern provided by UAD systems more efficiently remove contaminants from occupied spaces. In other words, air from the floor sweeps pollutants up and away from the breathing zone and reducing cross-contamination. Effectiveness is also increased in cases where users have the ability to relocate/add diffusers to match use patterns of the facility. Ventilation can be increased proportionally to need without awaiting thermal demand.

Energy
Taking into consideration factors such as ventilation effectiveness, stratification savings, higher supply temperatures and split task/ambient conditioning, UAD systems can identify between 5-25% energy consumption savings due to use of higher supply air temperatures. These air temperatures allow the use of economizer cycle for longer time, especially in mild climates. For systems that have split task ambient conditioning, savings can occur if task-conditioning operation is flexible and occupancy sensors in use. In addition, UFAD conditions only use the first six feet of space in a room, reducing supply air requirements and chiller and primary fan capacity as a result.

Cost
By combining all aspects of the HVAC system into one easily accessible service plenum, flexibility is increased and potential costs are avoided associated with re-configuring building services. Facility management costs decrease due to reduced occupant comfort complaints. These benefits allow for reduction in facility staff requirements and give the team the opportunity to complete preventive maintenance tasks.

Growth for this cost-effective technology has been relatively slow as with any unfamiliar technology. The perceived high risk to designers and building owners, lack of available information and standardized guidelines, and the perceived higher cost of a raised floor drive the resistance to implement UFAD technology.

Feeling unsure about its application? American AgCredit applied UFAD technology to their regional headquarters in Wichita, Kansas and experienced increased employee comfort compared with their previous facility’s traditional system. The award winning system design called for the use of a complementary unit that had the ability to provide very dry, comfortable, underfloor air that cooled slightly into the 60’s. American AgCredit utilized AAON DPAC units because of the product’s ability to efficiently cool all underfloor air while only dehumidifying a portion to lower humidity levels. Learn more.
