Building Energy Management Open Source Software (BEMOSS™) is a software platform that is engineered to improve sensing and control of equipment in small- and medium-sized commercial buildings. BEMOSS™ aims to offer: scalability, robustness, plug and play, open protocol, interoperability, cost-effectiveness, as well as local and remote monitoring. BEMOSS is developed at Advanced Research Institute, Virginia Tech and powered by VOLTTRON™.
BEMOSS™ is designed to have an open architecture to make it easy for hardware manufacturers to seamlessly interface their devices with BEMOSS™. Software developers can also contribute to adding additional BEMOSS™ functionalities and applications.
BEMOSS™ is designed to automatically discover supported load controllers (including smart thermostats, VAV/RTUs, lighting load controllers and plug load controllers) in commercial buildings.
Currently, BEMOSS supports the following prevalent communication technologies: Ethernet (IEEE 802.3), Serial (RS-485), ZigBee (IEEE 802.15.4) and Wi-Fi (IEEE 802.11); and protocols: BACnet, Modbus, Web, ZigBee API, OpenADR and Smart Energy (SE) protocols.
Implementation of BEMOSS™ is deemed to be cost-effective as it is built upon a robust open source platform that can operate on a low-cost single-board computer, such as Odroid. This feature can contribute to its rapid deployment in small- or medium-sized commercial buildings.
The BEMOSS™ software platform is designed with a multi-layer architecture where multiple single-board computers hosting BEMOSS™ can communicate among each other and to a master controller to monitor and control a large number of load controllers in a multi-floor and high occupancy building.
BEMOSS™ provides both local and remote monitoring ability with role-based access control.
In addition to built-in security features provided by VOLTTRON™ including agent authorization & authentication, encrypted multi-layer communication and agent validation, BEMOSS™ provides additional enhanced security features.
