BMS: automation of commercial buildings, hotels and industrial buildings in Constanta
Air conditioning, lighting, access and consumption, managed from a single system that knows whether the space is occupied or empty. The building costs less and is managed from a screen.

This page is about commercial buildings; for residential buildings see Smart Home for homes. In a building without BMS, air conditioning is running in empty rooms, lights are burning in the deserted parking lot and no one knows how much energy each floor consumes. With BMS, all of this can be seen and controlled from one place.
GreenSoft designs and implements building automation systems on KNX, Loxone or open platforms: air conditioning control after occupancy, lighting on scenarios and sensors, blinds, energy metering by zones, technical alarms (flood, temperature in the server room, open balcony door) and integration with access control and hotel reception.
For hotels, the BMS connects to the reception system: the room is prepared at check-in and goes into economy at check-out. For offices and industrial buildings, it shows consumption by cost center.
What does the service include?
- Design of BMS architecture and operating scenarios
- KNX, Loxone or open platforms (Modbus, BACnet) automation
- Control HVAC and lighting by occupancy, schedule and daylight
- Energy metering, reports and technical alarms
- Integration with access control, reception (PMS), CCTV and fire
Why GreenSoft
The BMS controls installations that we also do: electrical, HVAC, access, fire. We don't hide behind another supplier when something doesn't respond, and we secure the automation network according to ISO/IEC 27001 practices, so that it is not the gateway to the building.
How the project is progressing

- office buildings
- clinics
- shopping centers
- industrial buildings and warehouses
- public institutions
Tell us what installations the building has and what you want to control; you will receive a BMS architecture with a quote within 5 working days.
Where we work
We cover the entire county of Constanta: Constanta municipality, Mamaia, Năvodari, Ovidiu, Agigea, Eforie, Techirghiol, Mangalia, Medgidia and Cernavodă, including the port perimeter, based on the work license in the Port of Constanta. For larger works, we travel throughout Dobrogea.
Useful resources
- BMS or Smart Home? What's the difference?
- Is the building's KNX system secure?
- Hotel classification: what systems does the certificate require?
Frequently asked questions
How much does a BMS save?
In hotels, controlling air conditioning by occupancy significantly reduces HVAC energy because you are no longer cooling empty rooms. In offices, sensor-based lighting and operating schedules bring similar savings. We estimate based on your building data.
Can BMS be added to an existing building?
Yes, in stages: we start with what brings the most savings (usually air conditioning) and expand. Existing equipment is integrated via Modbus, BACnet or contacts.
KNX or Loxone?
KNX is the open standard, with thousands of manufacturers, suitable for large buildings and long-term. Loxone is faster to implement and cheaper for small and medium-sized buildings. We recommend it according to size and budget.
Is the BMS cyber secure?
We put it on a separate network, with remote access via VPN and personal accounts. A BMS exposed to the internet is the most common reason we have been called to "fix" a smart building.
