ABB Nsight vs BEMServer

ABB Nsight is a cloud-based analytics platform for industrial operators seeking visibility into site energy use and carbon performance. It centralizes water, air, gas, electricity, and steam data in one dashboard and includes utility bill and tariff analysis. The platform supports greenhouse gas baselining, reporting, and real-time monitoring for Scopes 1 and 2. Its listed levels cover reporting and tariff analysis, real-time meter and significant energy user monitoring, and optimization tools such as grid prediction, demand response optimization, and automated load curtailment. ABB says Nsight connects with ERP, BMS, SCADA, AMI, and IoT systems using open APIs and flexible protocols. It is designed to use existing meters, sensors, and systems without requiring new hardware in most cases. ABB describes encryption at rest and in transit, outbound-only data flow, and two-factor authentication, and states compliance with SOC 2 Type II, ISO/IEC 27001, and NIST standards. All three subscription levels include onboarding, training, and 24/7 support. The platform is available on web and via API; pricing is on request.

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.
