JACE, or Java Application Control Engine, is an open architecture network area controller commonly found in commercial and institutional building applications such as education, government, and healthcare. The JACE is part of the Tridium VYKON product line manufactured by Honeywell. For a period of time, Affinity Energy was an authorized system integrator. Because of their systems integrations in hospitals and data centers, Affinity Energy has maintained expertise in configuring and integrating JACE. We also use JACE when we are required to interface EPMS systems to building automation systems.
