The Opus Difference
A suite of products, software and hardware designed to control HVAC, lighting and refrigeration and perform energy management functions for multi-site facilities, Opus stands apart from other building controls systems in its open platform, flexibility and scalability. It is designed specifically for multi-site operations of 10 to 10,000 sites, offering a breadth of features and functions tailored to the needs of multi-site owners, operators and managers.

Open Platform
Taking the NiagaraAX Framework® to a new level of integration excellence, Opus is designed to remove the hurdles that have historically existed when integrating diverse smart devices within multi-site facilities. Opus integrates these devices regardless of the manufacturer or communication protocol (LonWorks®, BACnet® or MODBUS®) so you can centrally manage all of your energy consumption and building controls through one user interface.

Simple centralized control, unmatched flexibility, easy duplication from site to site and exceptional service support make Opus the ideal solution for multi-site energy-management and control needs.

To help you leverage your equipment investment even further, Novar ensures the compatibility of our technological advances with your legacy Novar equipment. Upgrades are quick and easy, and significantly less expensive than equipment replacement.

Flexibility
Think of Opus as a blank canvas: It can be programmed to resolve virtually any issue you might experience related to your energy management efforts, alarm strategies or HVAC, lighting or refrigeration control. The unique Opus architecture provides an unparalleled level of sophistication and flexibility to meet the most demanding and unique energy, operational and business requirements you face as you strive to lower operating costs and improve operational efficiencies.

Opus provides flexibility at the local level as well, recognizing that store managers and service contractors need access to system information. Custom user interfaces ensure that each member of your team has access to the most relevant information. 

Scalability
With Opus, you can manage thousands of sites - across the country or around the world - expertly and efficiently. Make a change in one site and broadcast it across your entire enterprise. Access, view and manage each of your sites through a standard Web browser. Enterprise-wide features and functions, developed by the global leader in energy management solutions, make Opus the standout among building controls systems.
