Port Administration of Lazaro Cardenas SA de CV (APILAC) wanted to upgrade and integrate its current systems into one BMS system. APILAC is based on a four story building, divided into two wings per floor where offices, meeting rooms, and other areas accommodate a number of employees.
For five years the building has been operating with several independent systems for HVAC, lighting and fire detection. Having each system work independently without an integrated management system has made it difficult to maintain and improve the energy efficiency of each system. As a result, the building managers issued a public tender to find a partner to help integrate these systems through a centralized BMS platform.
Port Administration of Lazaro Cardenas SA de CV turned to ISDE, a pioneer of home and building automation, as well as street lighting to solve and provide a solution for the following requirements:
To automate the building, ISDE chose to work with the proven LonWorks networking platform. With LonWorks, ISDE was able to integrate multiple system components such as lighting, HVAC, fire central panel, power monitoring and SCADA using a common system architecture and infrastructure – in essence, one set of
wires through which all components are attached and can share common information. Data can travel from any point on the network to any other point with no single point of failure, embedding high-level security and allowing full component interoperability in a peer-to-peer fashion. The comprehensive system provides an
intuitive and simple way to manage each system. For example one can control setting the scheduler, the temperature and lighting set point as well as limit the chillers capacity, monitor the AHU, chillers and VAVs.
According Ismael Duarte Correa – Head of the General Service Department of APILAC, “This BMS has allowed us to control the maximum demands, reducing our costs considerably, by modifying the time of use for the HVAC equipment.”
Thanks to LonWorks, the system can be maintained long term and can be expanded in the future because it based on the standard (ISO/IEC 14908), which makes it interoperable and supported by many manufacturers.
ISDE was able to reduce the changes of the electromechanical and lighting elements installed, by using the controllers from each manufacturer. For example for lighting control it uses ISDE controllers and for HVAC it utilizes Distech Controls controllers.
Cesar Martinez Fernandez, Technical Manager of ISDE & Apilac BMS Project Leader, quotes:
“Most of the installation we worked are based on new buildings, so it was a beautiful challenge for us to implement a control system inside a building that not only is constructed, but also have people working inside and with no planning of doing any kind of reform.
Thanks to the LonWorks technology we were able to solve any kind of challenge that were introduced, like installing the controllers next to the areas or cabling through all the Air ducts, lighting cable, etc, without the need of extending the cable.”
