BEMServer vs SAUTER Vision Center

BEMServer is an open-source platform for deploying a modular building energy management system. It gathers information from building management systems and sensors alongside weather, occupant feedback, building descriptions, and contextual data. The platform connects building hardware with data-oriented services, storing building models, time series, and events for access through documented REST APIs. Its data model follows IFC and Haystack standards. Processing modules interpret collected information to identify issues or inefficient operation and support recommendations and decisions. Listed modules cover fault detection and diagnosis, renewable energy simulation, energy management, load forecasting, indoor environmental quality, and visualization. The software is licensed under AGPL-3.0, and sellers using a modified version must publish their modifications under that license. There is no software license fee, although installation, configuration, maintenance, and selected modules may be paid services. The maker recommends help from someone with Python and Docker knowledge and says installation was tested on Debian 9. BEMServer currently supports building monitoring; other uses require extending its functionality.

SAUTER Vision Center is a modular system for building, room, energy, and maintenance management. It is designed for single buildings, dispersed premises, and projects such as offices, campuses, hospitals, and production facilities. Its HTML5 web interface works across operating systems and practically every internet browser without additional apps or plug-ins. Users can arrange responsive dashboards with widgets and templates. The Scenario Manager plans and runs predefined building automation procedures, while energy tools offer forecasting, ISO reference specifications, KPI analytics, and abnormal-operation notifications. An optional maintenance module supports plans, automatic order triggers, asset records, and ticketing. Integration options include BACnet/SC, native BACnet, OPC UA, OPC DA through a gateway, MQTT, and SAUTER novaNet. SVC 8.1 adds encrypted transmission through a BACnet/SC Hub, two-factor authentication, and single sign-on. Pricing is on request; SAUTER directs buyers to national sales organisations and provides a demo account on request.
