AI optimization in buildings – straight answers

What does Nuuka AI do?

Nuuka AI connects to the building’s existing automation system and uses it to optimize heating, cooling and ventilation in real time. As a result, energy consumption and emissions fall and indoor climate conditions improve.

Nuuka AI is a software service (SaaS) with three parts: Optimizer controls building systems, Diagnostics detects faults and anomalies, and Analytics reports energy consumption and indoor climate across the whole portfolio.

How much energy can AI optimization save in commercial buildings?

Typically 10–30% of a building’s energy consumption. The savings come from controlling heating, cooling and ventilation according to actual use instead of fixed schedules.

The amount depends on the building’s current controls, use and systems. Savings are usually largest where systems run on fixed schedules or heating and cooling operate at the same time.

Measured results

  • Colt House, London: ventilation electricity −35% (1 March – 30 June 2025), about 32.7 MWh and 8.7 tCO₂e less per year – results verified by a third party
  • YIT Sture697, Helsinki: energy consumption −13%, about €80,000 per year
  • Länsituuli School, Oulu: energy consumption −14%, 58 MWh per year
  • Onvest Vallila33, Helsinki: energy consumption −15%, 140,000 kWh per year

Can AI optimize an existing building automation system?

Yes. Nuuka AI operates on top of the existing building automation system and continuously optimizes heating, cooling and ventilation. In suitable buildings, no replacement of the existing BMS is required.

Nuuka works with all common building automation systems and is compatible with about 80% of buildings without major changes.

Measured results

  • Colt House, London: the solution was implemented on top of the existing building automation, and ventilation electricity fell by 35%

Does AI HVAC optimization require new building automation equipment?

Usually not. Nuuka AI uses the building’s existing automation, and no equipment replacement is needed in about 80% of buildings.

The solution is delivered as software as a service (SaaS), so it requires no upfront investment.

How does AI optimize HVAC systems?

Nuuka AI adjusts heating, cooling and ventilation predictively and automatically according to actual use, every 1–5 minutes around the clock.

Continuous control replaces fixed schedules and set-and-forget settings. At the same time, Nuuka AI Diagnostics detects faults and anomalies before they affect indoor air or energy use.

Measured results

  • YIT Sture697, Helsinki: optimization fixed temperature imbalances and air pressure issues, and energy consumption fell by 13%

How often does AI adjust HVAC settings?

Every 1–5 minutes, about 44,000 times a month. An expert typically adjusts a building 1–2 times a month.

Frequent adjustment keeps conditions on target even as the building’s use and load change during the day.

How can buildings reduce energy consumption without CAPEX?

By optimizing how existing building systems are controlled. Nuuka AI is delivered as a service on top of the existing building automation, so savings start without upfront investment or equipment replacement.

Many buildings waste energy through fixed schedules, poorly tuned controls, simultaneous heating and cooling, and unnecessary ventilation runtime. All of these can be fixed through control, without construction work.

Measured results

  • Onvest Vallila33, Helsinki: energy use and operating costs fell, energy consumption −15%

Does HVAC optimization affect indoor air quality?

Yes, and the aim is to improve it. Nuuka AI controls conditions according to actual use, so energy is saved without compromising indoor air or comfort.

Optimization continuously monitors indoor climate, and Nuuka AI Diagnostics detects anomalies before occupants notice them.

Measured results

  • Länsituuli School, Oulu: indoor air improved and electricity use fell
  • YIT Sture697, Helsinki: temperature imbalances and air pressure issues were fixed, and tenant satisfaction improved

Which buildings is Nuuka suited for?

Public and commercial buildings such as offices, shopping centers, schools, hospitals, logistics centers, airports and trade fair centers.

Does Nuuka help with energy and ESG reporting?

Yes. Nuuka AI Analytics brings energy consumption, indoor climate and building system performance into one view and calculates 200+ KPIs that support ESG and sustainability reporting.

What kind of company is Nuuka?

Nuuka Solutions Oy is a Finnish technology company that has been developing its services since 2012. It is headquartered in Helsinki and has customers in several countries.

In total 3,000,000 m² and 1,500 buildings are managed with Nuuka today.
