THE PROBLEM: PERFORMANCE DRIFT
In 2010 ETC Group began working with Banner Health to implement retro recommissioning (ReCx) projects for multiple facilities, achieving significant energy savings. Over time, performance drift on past ReCx projects eroded much of the
savings that had been achieved. It was also important to ensure Banner facilities would deliver comfortable environments for patients and staff as well as maintain compliance and improve reliability of critical systems. Banner adopted an enterprise-wide approach to energy savings and organized an energy management team and a remote operations center (ROC). Banner’s ROC and ETC Group collaborated to focus on maintaining cost and energy savings, while meeting environmental and compliance standards across more facilities.
TURNKEY MONITORING-BASED COMMISSIONING
ETC Group introduced a monitoring-based commissioning (MBCx) program that
was piloted at the Banner Thunderbird medical center in Phoenix. Significant
annual savings was achieved for this initial pilot, including $449,000 in lower
energy costs, and energy savings of 4.7 million kwh and 13,600 dtherms.
To eliminate performance drift and proactively address energy savings on a
broader level, Banner and ETC Group created a system that would be replicated
across Banner’s facilities. Banner’s energy management team and ROC worked
with ETC Group to monitor, analyze, and enact plans to maximize energy savings.
The consolidated communications and shifting the mindset from project-based
work to a turnkey approach with ETC Group has accelerated Banner’s ability to
identify issues and enact change.
ENABLING POWERFUL MBCx TOOLS
The program leverages advanced MBCx tools such as SkySpark®, ClimaCheck® and BuildingFit™, a powerful smart building analytics and visualization tool. A custom reporting dashboard was also developed by ETC Group and BuildingFit™ to meet Banner’s unique needs. These tools and analytics make energy efficiency efforts more agile to reach greater energy savings faster, all while establishing new systems for
better environmental and compliance controls.
ETC Group’s turnkey MBCx program includes three phases, totaling 25 Banner Health buildings (13M ft2 ). ETC Group’s work for the ten buildings (4.2M ft2 ) in Phase I has resulted in $3.84 million in annual cost savings, including 14M kwh and 88K dtherms in annual energy savings. Phase I results have exceeded cost savings estimates by about $1 million. Work for Phase II (nine more buildings and 4.5M ft2) is underway and is
on track to deliver similar results. Phase III work has just begun and includes six more buildings (4.2M ft2).
Banner streamlined communications and decision-making by creating ROC and teaming with ETC Group. Issues are now identified and corrective actions taken faster than before. As a result Banner now proactively combats performance drift to maintain energy savings. The use of key smart building technologies provides actionable data for smarter and more efficient decision-making. The BuildingFit™ team works to continuously develop new tools to save energy, ensure code compliance and improve overall reliability of equipment.
