BEMServer vs Enertiv

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.

Enertiv is a sustainability platform for commercial real estate portfolios, with tools for reporting, decarbonization, and energy efficiency. Its Energy & ESG module handles utility bill intake and quality checks, portfolio benchmarking, and reporting for regulatory and investor requirements. Tenant utility data can be gathered through a portal, shadow metering, or mobile meter reads with quality checks. Reporting connects with Energy Star Portfolio Manager and exports formatted data for GRESB, SFDR, CSRD, and TCFD. Carbon Planning uses equipment details collected in on-site surveys to generate AI-powered operating and capital expenditure recommendations. For building performance and maintenance, Enertiv can connect to an existing building management system or install monitoring devices; work orders can be linked to equipment alerts and runtime-based preventive schedules. Yardi and MRI integrations sync tenant and billing information. Customers can access platform data through the interface or RESTful API, and Enertiv says it stores data indefinitely. The free portfolio diagnostic uses read-only ESPM data; paid module pricing is available on request.
