Platform
one platform for everything a building does
Heating, cooling, ventilation, lighting, shading, access, metering and alarms — one system, one BMS, one supplier responsible. Bisly hardware and software, configured in a digital twin and run from bisly.cloud.
What it controls
Every building function, per unit and for common areas
01
Heating and cooling
Room by room: radiators, floor heating, fan-coils, split and VRF units; pre-heat on occupancy; hydronic balancing support.
02
Ventilation and air quality
AHUs from 20+ manufacturers; CO₂ and humidity demand control per room; heat-recovery supervision.
03
Lighting
DALI-2 presence and daylight control; existing wall switches reused as inputs; Matter lighting where no cabling exists.
04
Blinds and shading
By sun position, glare and occupancy; scenes per room and per facade.
05
Access and intercom
Readers, locks, video intercom and lifts in the same BMS, with per-tenant credentials and time rules.
06
Metering and billing
Electricity, heat, water and gas per meter and per tenant; billing-ready exports; spike alarms.
07
Price-based control
Day-ahead prices shift setpoints and loads; links to EV charging and storage from AMP X VOLT.
08
Security and alarms
Leak, smoke, open window and intrusion inputs; prioritised alarms by SMS and e-mail, with the room named.
Lighting
Dimmable, daylight-led and circadian
Presence and lux sensors measure the light in every zone; the controller compares it with the required level and sets the dimmers, so daylight comes first and the luminaires add only what is missing. Scenes set a room for work, meetings, presentations, dinner or cleaning. Tunable white follows the natural day — brighter and cooler in the morning, warmer and lower in the evening — to support the circadian rhythm, mood and sleep. Bisly developed its human-centric lighting control with TalTech.
- DALI-2 on the same system as heating and ventilation: DALI Bridge 2 with 64 drivers per line, colour and tunable white (DT6/DT8), Presence Sensor with lux measurement
- Matter lights and wall switches where there are no control cables (Bisly Wireless)
- Scenes from the wall panel, the app, a push button or the schedule
- Savings by space: open office 7–36 %, office rooms 10–70 %, meeting rooms 22–64 %, classrooms 14–76 %, toilets 33–90 % (Bisly figures)
- Average savings in an LBNL meta-analysis: 24 % from occupancy control, 28 % from daylighting, 38 % from combined strategies (Williams et al., 2012)
- Supports WELL v2 feature L03 Circadian Lighting Design and BREEAM Hea 01 Visual comfort
Digital twin
Configured, not programmed
Labour is 50–75% of a conventional controls project (NREL/JISEA, 2022). Bisly removes that part: every function is a configuration choice in the digital twin, so no controller code is written for any site.
- 01Sell: the Sales Configurator builds floors, rooms and functions.
- 02Win: quote and bill of materials per room and per panel.
- 03Generate: wiring, panel configuration and logic, pre-configured and factory-tested.
- 04Install: the Installer App — room first, device second, no laptop at the panel; automated documentation.
- 05Operate: the twin stays live in the BMS and becomes the template for the next building.
BMS and Adam
What the facility manager finds where
bisly.cloud runs in any browser, with a mobile app for alerts and overrides. One login covers a whole portfolio.
- 01
Rooms and spaces
Floor plans with live temperature, CO₂ and humidity per room, coloured by state, with alarm badges. The room behind a complaint is found in seconds.
- 02
Equipment
Live schematics of substations, heat pumps and AHUs; setpoints, modes and heating curves edited on the schematic.
- 03
Meters
Electricity, heat, water and gas per meter, virtual meters, day/night split, tenant allocation; PDF, CSV and Excel.
- 04
Alarms
Priorities, delays, comments, SMS and e-mail; silent sensors and stuck actuators detected automatically.
- 05
Schedules and automations
Per AHU, lighting group, room or tenancy, with a holiday calendar and every run on a timeline.
- 06
Trends
1-minute data for 30 days, 15-minute for a year, hourly for five years; Excel export.
- 07
Adam, the AI assistant
Explains sensor drift, stuck actuators and short cycling in plain language; ranks a portfolio by energy, indoor air and alarms.

What it saves
Savings compound only when the full stack is installed
A thermostat alone saves little. Room control, hydronic balancing and plant optimisation together are where the 20%+ comes from.
