For municipalities and public owners

healthy classrooms, lower bills

Fresh air when the classroom needs it, heat and light that follow the timetable, energy per building for the municipality — installed new or during the school year.

    CO₂ drives the air

    Each classroom's ventilation follows its own CO₂ reading: concentration stays healthy, and empty rooms get no air they do not need.

  2. 02

    Timetable drives heat and light

    Lessons, holidays and evening use set heating, ventilation and lighting per room.

  3. 03

    Good light, less energy

    Presence and daylight dimming per classroom, scenes for teaching, the board and presentations, and tunable white that follows the school day for the circadian rhythm — at Ehte Gymnasium classrooms reached 500 lux with LEDs and multisensors.

  4. 04

    Ventilation units supervised

    AHUs on one schematic with alarms; filters, fans and heat recovery monitored.

  5. 05

    Sports halls on their own schedule

    Evening clubs and weekend use without heating the whole school.

  6. 06

    Solar and storage

    Rooftop PV used first, with price-aware heating and charging.

  7. 07

    Energy per building

    Consumption and indoor air per building for the municipality, ranked across the portfolio for reporting.

Lighting

Classrooms in good light — and the right light

Illustration of human-centric lighting: tunable white follows the natural day, warm and low in the evening, bright and cool around midday. Bisly developed its human-centric lighting control with TalTech.

Each classroom holds its lux level with daylight first and dims with presence; scenes switch between teaching, the board and presentations. Tunable white follows the school day — bright and cool in the morning, warmer in the afternoon — to support pupils' circadian rhythm and attention. Bisly developed its human-centric lighting control with TalTech.

  • Presence and daylight dimming per classroom
  • Scenes for teaching, the board, presentations and cleaning
  • Tunable white for the circadian rhythm (DALI-2 DT8)
  • Savings in classrooms: 14–76 % (Bisly figures)

Rules for public owners

Public buildings lead the EU energy rules

  1. 2026

    Solar on public roofs

    Solar installations on all new public buildings by 31 December 2026, and on existing public buildings above 2,000 m², 750 m² and 250 m² by 2027, 2028 and 2030, where feasible (EPBD Art. 10(3)).

    Public-building rules
  2. 2028

    Zero-emission new public buildings

    New buildings owned by public bodies must be zero-emission from 1 January 2028 (EPBD Art. 7), with indoor air quality measurement and control in non-residential ZEBs (Art. 13(5)).

    EPBD
  3. EED

    3 % renovated and −1.9 % energy, every year

    Public bodies renovate at least 3 % of the floor area of their heated or cooled buildings above 250 m² each year (EED Art. 6) and cut final energy consumption by at least 1.9 % a year against 2021 (Art. 5).

    Public-building rules
  4. 2030

    Renovation of the worst performers

    16 % of the worst non-residential stock renovated by 2030, 26 % by 2033 (Art. 9) — schools and municipal buildings among them.

    EPBD
  5. BACS

    Automation above 290 kW and 70 kW

    Larger schools and sports halls fall under the BACS duty now; mid-sized ones by 31 December 2029.

Installed during the school year

With Bisly Wireless, classrooms get room-level control without cabling through finished rooms — as at Vanalinna Hariduskolleegium, Tallinn, where wireless lighting control went in during the school year.

What municipalities ask

“How much energy can building automation save in schools?”

Bisly reports 20–35 % energy savings across more than 30 schools and public buildings, from ventilation by CO₂, heating and lighting from the timetable and room-level control.

“Can classrooms be automated without closing the school?”

Yes. Bisly Wireless installs room-level control without new cables, floor by floor during the school year, as at Vanalinna Hariduskolleegium in Tallinn.

“What do new public buildings need under the EPBD?”

From 1 January 2028 new buildings owned by public bodies must be zero-emission buildings (Art. 7); non-residential zero-emission buildings need indoor air quality measuring and control devices (Art. 13(5)).
