Escondido Union School District
Sustainable building management
San Diego, CA
Escondido Union School District (EUSD) recognized an opportunity to enhance its educational facilities in North County San Diego by upgrading its building automation and controls system, and HVAC equipment.
EUSD’s legacy Carrier Controls Network (CCN) systems, although reliable for over two decades, were beginning to show their age. Challenges with parts availability and limited integration capabilities with modern sensors and analytic tools were identified. Third-party wireless thermostats, while providing some wireless connectivity to the i-Vu system, were found to be less reliable than contemporary high-speed networks.
To enhance efficiency, extend the lifespan of the HVAC system, and support future growth, EUSD sought to implement a modern controls platform that could seamlessly integrate with their existing i-Vu® front end. Concurrently, EUSD chose to update the existing HVAC equipment as well to help provide more comfortable and healthy learning environments throughout the school district.
Project Solution
The decision to upgrade to modern Carrier controls was influenced by the local Carrier Distributor, Russell Sigler, Inc. and the level of customer service they provide, the proven performance of the existing i-Vu system, and budgetary considerations. This choice also aligned with the district’s focus on indoor air quality, energy management, and providing healthy learning environments.
To upgrade without disrupting the existing system, EUSD opted for Carrier TruVu dual IP controllers, a field-installable solution. These controllers, equipped with high-speed BACnet/IP connectivity, offer scalability and flexibilty, accommodating future expansion while seamlessly integrating with the i-Vu front end. This provided facilities with a seamless experience without having to learn a new user interface. The district also secured the necessary materials to modernize the systems with approximately 500 pieces of HVAC equipment, mainly Carrier rooftop units, chillers and split systems.
