Nuuka AI
Nuuka AI is a Finnish SaaS platform that layers machine learning over existing building automation systems to optimise heating, cooling and ventilation in commercial and public property, claiming 10-30% energy savings with no upfront investment.
What is Nuuka AI?
Nuuka AI is the energy and indoor-climate optimisation software published by Nuuka Solutions Oy, a Helsinki company that says it has been developing its services since 2012. It is sold as software as a service for public and commercial properties, and its central design choice is that it does not replace a building management system: it sits on top of whatever automation already runs the plant. Nuuka states that it complements all market-available building automation systems and is compatible with 80% of buildings without major changes to existing equipment.
The product is presented as three modules. Nuuka AI Optimizer predictively adjusts ventilation, heating and cooling to actual need. Nuuka contrasts its cadence with human practice: optimisation commands every one to five minutes, up to 44,000 a month, against the one or two monthly adjustments a building expert would make. It claims 10-30% energy savings from this, with figures of 50% on ventilation energy and 30% on cooling shown on the solutions page. Nuuka AI Diagnostics shifts maintenance from reactive to predictive, identifying performance issues, usage errors and technical faults before they reach indoor air quality or consumption, and claims a 75% cut in manual monitoring with problems resolved twice as fast. Nuuka AI Analytics gathers indoor air, energy and plant performance into one interface, calculating more than 200 property KPIs from individual devices up to a whole portfolio, and is positioned as feeding sustainability reporting.
The headline claims on the homepage are up to 30% less energy, 30% less CO2, 75% less manual work and optimised conditions around the clock, all argued to require no upfront investment. Access is through a web portal at nuukaportal.com, whose interface offers English, Finnish and Swedish. Nuuka sells directly to property owners and through a partner network of local maintenance and HVAC firms. Three customer cases are published, at a YIT office building, a school in Oulu and an Onvest business park, each with figures reported for those clients' own buildings. There is no published price, no trial and no API.

When to use Nuuka AI / When not to
A quick filter to help you decide if Nuuka AI is the right fit.
When to use Nuuka AI
- Property owners and real-estate investors managing a portfolio of commercial or public buildings
- Facility management teams running several sites who want to supervise them from a single platform
- Building services and HVAC engineers responsible for indoor climate and plant performance
- Sustainability and ESG teams that need continuous energy and indoor-climate data for reporting

Pros & Cons
Pros
- Concrete, repeated performance claims: 10-30% energy savings, up to 30% less CO2 and 75% less manual supervision
- Three customer cases published with detailed figures, measured on those clients' own buildings
- Sits on top of existing building automation rather than replacing it, which limits capital works
- No upfront investment is required, according to the vendor's commercial argument
- Product interface available in English, Finnish and Swedish
- Unusually complete legal identity: business ID, VAT number, registered address and named managing director
- Established publisher: Nuuka says it has been developing its services since 2012, and its investors are identifiable from public releases
Cons
- No public pricing whatsoever: no rate card, no pricing page, and a 404 where one would expect it
- Neither a free plan nor a free trial is offered, so evaluation requires a sales conversation
- No API and no developer documentation of any kind
- No mobile application; the product is reached only through a web portal
- No security commitments published: no trust page, no certification claimed and no subprocessor list
- The data hosting country is never stated, and the privacy notice is silent on building data
- No terms and conditions are published, so contractual conditions cannot be reviewed before contact
Pricing & Plans
Nuuka publishes no price for Nuuka AI. There is no pricing page on the site, and the address where one would normally sit returns a 404, so the absence is confirmed rather than assumed. No permanent free plan and no free trial are advertised. The product is sold on quotation, and the single call to action across the site is to contact the company. Readers should note that the vendor's repeated promise of no upfront investments refers to the absence of initial capital expenditure, not to the product being free of charge. A savings calculator is offered on the homepage, but it estimates potential energy savings and never the cost of the service.
Data, GDPR & hosting
A consolidated view of how Nuuka AI handles your data.
GDPR overview
The word GDPR appears nowhere on Nuuka's website, and the company never claims compliance in so many words. What it does publish is a privacy notice, last updated on 5 May 2026, written along GDPR lines: it names its legal bases, including consent, contract, legitimate interests and legal obligation, and it enumerates data subject rights covering information, access, rectification, erasure, restriction, withdrawal of consent, objection and complaint to a supervisory authority in the member state of residence, work or alleged infringement. Transfers outside the EU and EEA are said to rely on Standard Contractual Clauses or a Commission adequacy decision, with data processing agreements in place within the EEA where needed. No DPO is named and no Article 27 representative is designated, which is consistent with a Finnish controller established inside the EU. Rights are exercised by writing to info@nuuka.com.
Who owns the data?
Nuuka Solutions Oy is the controller for the personal data it describes, and its privacy notice is limited to external stakeholders such as customers, suppliers, marketing leads, event participants and media contacts. The company states that processing is partly outsourced to service providers, ranging from server capacity to vendors who actually see the data, and that contact details may be passed to dealers, distributors and service workshops. Crucially, the notice never addresses ownership of the building telemetry the product itself collects, and Nuuka publishes no terms and conditions at all, so the contractual position on customer and building data cannot be established from the website.
Reuse rights
Nuuka publishes no terms and conditions, so nothing on the site grants or restricts a customer's right to reuse the data the product generates. The privacy notice covers only personal data, and lists the purposes Nuuka claims for it: managing the relationship, marketing and communication, event registration, quotes, orders and invoices, customer service, and administering the applications it provides. Nuuka also states that it profiles individuals by relationship type, by interests gathered through cookies and by system registrations, and that this profiling feeds targeted and automated marketing. On the product side, the Analytics module is presented as giving customers real-time portfolio data and over 200 calculated KPIs to support their own decisions and sustainability reporting, but no reuse rights are spelled out.
Data retention & training
Hosting summary
Nuuka states neither a hosting country nor a hosting region for customer data, and publishes no trust or security page from which either could be inferred. Its privacy notice says that processing is partly outsourced to service providers, ranging from the purchase of server capacity to services whose providers actually see the data, and that each provider may process personal data only as far as the service requires. Transfers outside the EU and EEA are contemplated, and are said to rely either on a European Commission adequacy decision or on Standard Contractual Clauses; within the EEA, data processing agreements are described as being in place where needed. No list of subprocessors is published. The publisher is established in Finland, and the marketing site is served behind a content delivery network, but neither fact indicates where product data actually resides. In short, the legal framework for transfers is described while the physical location of the data is not.
Things to keep in mind
Risks and trade-offs to weigh before adopting Nuuka AI.
- Every performance figure on the site is the vendor's own claim and none is independently audited
- The case study results belong to those clients' buildings and will not transfer mechanically to another site
- No upfront investment refers to capital expenditure only; the recurring cost of the service is never disclosed
- The hosting country is not stated and transfers outside the EU and EEA are explicitly contemplated
- The privacy notice says nothing about the building data the product collects, nor about any model training on it
- With no published terms and conditions, contractual conditions cannot be reviewed before engaging with sales
- Delegating continuous plant control to an automated optimiser can erode in-house understanding of how a building actually behaves
Setup & Integrations
Technical difficulty
Nuuka describes a light integration: the software connects to the building's existing technical systems, is said to suit 80% of buildings without major changes, and requires no upfront investment. In practice the effort is not the customer's to estimate, because there is no documentation, no installation guide and no API. Deployment is carried out by Nuuka or by a local partner, so this is a vendor-led project rather than a self-service setup. The real prerequisite is a controllable automation system driving heating, ventilation and cooling. No commissioning timescale is published.

Should you pick Nuuka AI?
Nuuka AI is a focused, credible piece of building software let down by how little its publisher is willing to put in writing. On the functional side the picture is clear: three modules that optimise HVAC continuously, predict faults before they surface, and turn the resulting data into more than 200 KPIs, all layered onto existing building automation rather than replacing it. Three customer cases are published with real figures, measured on buildings belonging to YIT, a municipal school in Oulu and Onvest, and the legal identity of Nuuka Solutions Oy is fully verifiable down to its business ID and managing director. The investor base is identifiable too, with documented rounds from Loudspring and YIT Ventures.
The reservations are commercial and documentary rather than technical. There is no price, no trial and no self-service route in, so any evaluation begins with a sales conversation. More striking for a product that ingests continuous building telemetry, Nuuka publishes no terms and conditions, no security page, no certification claim, no subprocessor list and no hosting location, and its privacy notice addresses only the personal data of business contacts, never the building data the software collects. The word GDPR is not used anywhere on the site. None of this proves a weakness in the product, but it does mean that a prospective buyer must obtain in a contract what many vendors publish openly.
For an owner or facility manager running a tertiary or public portfolio already fitted with a controllable automation system, Nuuka AI is worth a conversation. For anyone who needs to compare prices, self-serve, or audit data governance before making contact, this site will not answer the question.
