St. Louis Aquarium & MallA Jarrell Case Study

Project Overview

With Jarrell Mechanical’s involvement in the installation of a Distech Building Automation Energy Management System for the Union Station Hotel (in 2018), it was an ideal fit to task Jarrell Mechanical with the extension of the hotel’s BAS to the new HVAC systems in the renovation of the mall area and the addition of the St. Louis Aquarium.

Valuable Integration

Of course, this was no small feat. The existing property featured two separate control platforms. The Hilton Hotel at Union Station was controlled by Siemens Insight, while Union Station had a Honeywell Excel 5000. We removed both legacy systems and replaced them with one OPEN platform BMS, EC-Net 4 / Tridium Niagara 4.

“The open structure of EC-Net building management system (BMS) creates a common development and management environment for the integration of BACnet®, LONWORKS®, Modbus™, and other standards,” explains Rick Clary. “More than a building management system, EC-Net system provides all the tools you need to gain intelligence into your buildings’ performance and arm you with the ability to rapidly react to any situation that may adversely affect energy costs, business performance, and ultimately, your bottom line.”

Award-Winning Controllers

For the connected equipment we selected Distech’s award-winning line of BACnet/IP ECLYPSE Controllers.

“ECLYPSE Connected BACnet/IP and Wi-Fi HVAC Controller Series, and ENVYSION responsive, web-based design and visualization interface, provide powerful connectivity, and advanced control, monitoring and analysis, for your Internet of Things building,” says Tony Buck. “The ECLYPSE controller series utilizes BACnet/IP and IT standards, delivering empowered IP connectivity and open integration with building management systems. You can choose wired IP, Wi-Fi, or combine both on a same controller to suit the building’s infrastructure, architecture and layouts.”

Accomplished Goals

  • Provided an OPEN Platform system that allows easy upgrades and modifications for years to come. 

  • Empowered support staff with the ability to see and make changes - to the entire complex - on a single mobile device or a networked workstation.  Staff now have the flexibility to move around while still being confident that control of their building is secure with authenticated connections no matter where they are in the world.

  • Extended the "automated system" from the hotel to all of the attractions, restaurants, and the Aquarium.
