Naval Station Mayport had a vision to pursue energy savings by investing in equipment upgrades and utilizing various innovative strategies and technical integrations with the current base wide EMCS system. The decision was made to utilize the Utility Energy Service Contract (UESC) vehicle to implement these measures.
TECO Peoples Gas (TECO) was the utility selected to work with their technical team and determine the types of upgrades that could provide substantial benefits the base. TECO chose to use Energy Systems Group and Professional Cooling & Control Systems to meet and support the challenges and goals of the Energy Project at the base.
As part of this latest Energy Project, the Navy wanted to add additional capabilities and features to the current base wide Direct Digital Control (DDC) System. This system was originally put in place in 2013 to provide “real-time” control and data monitoring to track energy savings and help identify any issue that would result in significant reductions in energy consumption for each building that is connected to the system.
This current project would also provide for additional buildings to be upgraded to new DDC controls and integrated to the centralized EMCS Niagara workstation.
The project included the installation of various approved industry standard communication protocols including BACnet MS/TP, BACnet IP, and LON based integration. Several features implemented and tested included customized graphics reporting, customized strategic equipment programming, scheduling of approved equipment, run time trends and alarming of points. This project also included installing localized electrical Power Monitor stations in various “high energy” buildings throughout the base to allow for detailed trending of each building’s energy usage and history.
After the installation, setup and testing of the new hardware and software (including Distech Niagara JACE front-end controllers) was completed, the system is able to manage over (1500+) individual equipment devices.
The Navy has found that the “open protocol” Niagara software has provided significant contributions toward reductions in energy usage while also providing significant benefits in forecasting equipment efficiency and possible failures.
This system has also enabled a method to centralize the control of building temperature set points and has also helped to further reduce energy usage base wide.
The success of this project has resulted in a complete “centralized building control” system to achieve both maximum energy savings and providing accepted occupant comfort levels in each building. To assure the future integrity and durability of this system a maintenance and support contract was included as part of this project.
This will assure that the the integrity of the base wide EMCS System hardware and software is maintained while also providing support for any future energy goals and upcoming expansion projects at NS Mayport.
With the support of the BEM (Building Energy Monitor) Program and its members, NS Mayport has increased their focus on their Energy Program to help create a sustainable culture in which energy conservation and efficiency is not only possible but takes center stage.
