Indoor Climate & Energy Optimization Solution for buildings without a Building Management System (BMS)
Nomestic uses room-level climate data to automatically fix ventilation issues and unlock financial savings. Healthier people, lower energy consumption, and a smaller CO2 footprint.
Illustration of the Nomestic loop: sensors detect a CO2 problem in one room, the system opens the outdoor-air damper from 18% to 38% automatically, and CO2 returns to a good level.
Why
What the new Building Automation and Control System (BACS) rules means for you
01
Why BACS is required?
Utility buildings must continuously monitor and optimize their installation.
25-30%of energy is wasted in many buildings through poorly configured systems.
02
When does this apply to my building?
BACS is mandatory for non-residential buildings with HVAC systems.
January 1, 2026Installations with nominal capacity > 290 kW
January 1, 2030Installations with nominal capacity > 70 kW
Nomestic helps with compliance:
Measure
Track energy use and indoor climate continuously, and keep the record.
Maintain
Benchmark performance, find efficiency losses and faults, and tell the building manager.
Translate
Communicate with the installed HVAC and correct it automatically.
How
Monitoring, analytics and fully automatic control in one loop
Room-level data becomes verified ventilation energy savings, and your team doesn't have to chase every issue.
-
Ventilation performance and maintenance issues, room by room.
-
Issues become automatic adjustments on your existing Ventilation System.
-
Maintenance costs, Ventilation energy use, and CO2 emissions
-
Energy cost savings per m². Ready for your compliance report.

FAQ
Common questions
Do I need to replace or modify my HVAC system?
No. Nomestic sits on top of your existing HVAC and adjusts it automatically. Nothing is replaced or rebuilt.
Does it require a Building Management System (BMS)?
No. Nomestic works without a Building Management System (BMS).
How long does installation take?
Our devices are wireless and battery-powered, so each room takes minutes. There is no cabling and no downtime.
Can my team override automatic adjustments?
Yes. Every change is visible in the dashboard, and operators can override or pause automatic control at any time.
How are savings verified?
Nomestic compares measured energy use and indoor climate before and after each adjustment, using the same sensors, and reports the savings per m².
How does Nomestic help with EPBD IV?
It measures indoor environmental quality room by room, keeps it healthy automatically, and turns the data into compliance evidence and energy-saving reports.
