BMS & EPMS Systems

A BMS (Building Management System) is a centralized platform that monitors and controls a building's technical installations — HVAC, lighting, security, and access — from a single point. By automating schedules, adjusting setpoints based on occupancy, and detecting abnormal consumption, a BMS can reduce building energy costs by 20% to 40%.

The BMS collects data from temperature, humidity, and air quality sensors distributed throughout the building. A central controller processes the information and automatically adjusts chillers, boilers, AHUs, and fancoils to maintain comfort with the lowest possible consumption, applying zone-based and time-based regulation.

Among the most recognized manufacturers are Schneider Electric (EcoStruxure Building), Siemens (Desigo CC), and Honeywell (Niagara / Tridium). At Nexum Automatics, we are certified integrators and select the platform best suited to each project.

Yes. Modern BMS systems support open protocols such as BACnet, Modbus, and KNX, allowing you to connect sensors, actuators, and IoT gateways from different manufacturers on a single supervision platform.

The cost varies depending on the number of rooms, existing installations, and the desired level of automation. For a hotel with 50 to 150 rooms, the investment typically ranges from €30,000 to €90,000, with a usual payback period of 2 to 4 years thanks to energy savings.

There are major manufacturers such as Schneider Electric, Siemens, and Honeywell, as well as specialized integrators like Nexum Automatics, who design, program, and commission turnkey BMS systems tailored to each type of building.

A BMS manages and automates building installations (HVAC, lighting, access control, etc.), while an EPMS (Electrical Power Management System) focuses on electrical monitoring: it measures consumption in real-time, analyzes power quality, generates reports, and detects deviations. Both systems are complementary and, when combined, provide total control over comfort and energy efficiency.
