BEMServer vs KERO

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.

KERO is energy management software for industrial and commercial sites. Meters, IoT sensors, and connected systems feed live readings for energy consumption, demand, and cost at equipment and site level. The platform can flag anomalies and waste, support demand forecasting and peak-demand management, and measure changes against a baseline. It describes automated demand response and load balancing, with options to schedule or override responses. Continuous sub-metering builds audit records, and KERO produces structured reports for Malaysia’s EECA 2024; the customer's Registered Energy Manager signs off. An open API connects to building-management systems and other data sources. KERO names equipment brands including Daikin, Carrier, Trane, ABB, Danfoss, Honeywell, Huawei, and Solis, and says it can read TNB utility data. Modules cover monitoring, solar, batteries, EV charging, water, ISO 50001, ESG, and carbon credits, with availability varying by sector. The service runs on cloud infrastructure, with edge computing for local responses where latency matters. Dashboards and reports are accessible on mobile devices. Pricing is on request; prospective customers can book a demo.
