In Bulgaria and Europe, energy costs are one of the biggest challenges for businesses and building owners. Heating, air conditioning, lighting, and electrical appliances often consume over 40% of the monthly budget. The solution is building automation (BMS – Building Management System), which allows for centralized control and intelligent use of resources.
According to EU statistics, companies that have implemented BMS reduce their energy costs by up to 30% in the first year.
What is a BMS system?
BMS (Building Management System) is software and hardware that controls the main systems in a building:
- 🌡 Heating, ventilation, and air conditioning (HVAC).
- 💡 Lighting.
- ⚡ Electricity distribution and energy management.
- 🔒 Access control and security.
- 🚨 Alarms and detectors.
The system collects data from sensors and controllers and automatically makes decisions—when to turn a device on or off, how to optimize the temperature, or when to dim the lights.
How does BMS reduce energy bills?
- Smart heating and cooling
- Sensors monitor the temperature and the presence of people.
- If the room is empty, the air conditioner switches off.
- If the sun is shining, the heating is automatically reduced.
- Automated lighting
- The lighting only works when needed.
- In corridors and offices, it is activated by a motion sensor.
- In daylight, the lamps reduce their intensity.
- Energy monitoring
- Electricity, water, and gas consumption are monitored in real time.
- The system alerts you when limits are exceeded or leaks are detected.
- Managers receive analyses and forecasts for bills.
- Integration with smart devices
- The system can control boilers, servers, and machines.
- Programmable scenarios – “Night mode” or “Weekend mode” – automatically reduce consumption.
Real examples from Bulgaria and Europe
🏢 Office building in Sofia
Implementation of VAiOS BMS led to:
- Reduction of electricity bills by 28% in the first year.
- Optimization of air conditioners – they only operate when necessary.
- Increased comfort for employees..
🏭 Industrial facility in Varna
- Electricity costs are reduced by 32%.
- Production lines are controlled centrally.
- The system detects and prevents energy losses.
🌍 Europe
In Germany and Belgium, BMS is standard for every new commercial building. The investment pays for itself in 3–5 years on average, and the property value increases by up to 20%.
How much does a BMS system cost?
The price depends on:
- Size of the building.
- Functions (lighting, air conditioning, security).
- Level of automation.
💰 Average:
- Small office (200–500 sq. m): from BGN 10,000 to BGN 20,000.
- Medium-sized building (500–2000 sq. m): from BGN 30,000 to BGN 60,000.
- Large business or industrial facility: BGN 100,000+.
⚡ However, the reduced bills make the investment extremely profitable.
Business benefits
