A platform dedicated to the energy performance

The World’s premier Open Source
Building Energy Management Platform

BEMServer, a building energy management platform

BEMServer is an open source solution to deploy a modular, scalable and secure Building Energy Management System.

With the increasing amount of data to monitor buildings, it becomes crucial to offer tools that help managers in taking the best decisions to better control the energy of their buildings, and to involve all actors in reducing their environmental impact.

BEMServer was created to ease the deployment of these services, and to allow building managers to install applications that answer to their specific needs, instead of being confined to a monolithic, rigid solution.

Open source

With the power of open source, BEMServer goes even further: every software developer can contribute in augmenting the functionalities of the energy management solution, and make the overall community benefit from it.

The solution installed does not rely on a unique contracted company but can be maintained by any expert entity.

BEMServer empowers developers worldwide to join together in making buildings more efficient.

BEMServer is a solution for 3 kinds of stakeholders:
End-users, module developers and contributors.
