BEMServer vs CIM PEAK

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.

CIM PEAK is an AI-powered building analytics platform for property owners and operating teams. It combines utility, building, and equipment information into a unified portfolio dataset, then continuously monitors equipment performance, utility use, tenant comfort, safety, and compliance. Its automated fault detection and diagnostics rules engine identifies building problems and sends alerts with step-by-step solutions. Teams can assign tasks, track progress, and upload photos from phones or tablets in a centralized workflow. PEAK is described as BMS-agnostic, connects with existing building systems, and can send alerts through Teams or Slack. Portfolio benchmarking, equipment health insights, and capital planning use real-time equipment performance data. Listed capabilities include portfolio energy monitoring, carbon tracking, automated utility-data import, and API access. The service runs on web, Android, and iOS. Pricing is on request and based on required data points. Partner pricing includes edge hardware, cloud hosting, onboarding support, and team training, with unlimited users per building.
