Looking for a Nuuka alternative? Here's one that doesn't touch your controls.

FrostLogic Explore and Nuuka both watch a building around the clock, but Nuuka's Optimizer writes commands straight into your HVAC system while Explore only recommends and leaves your team in control. Nuuka is the closest Nordic competitor we have, built in Helsinki with a track record across a thousand City of Helsinki buildings. Here's exactly where each one is the right pick.

Why we're comparing ourselves to the closest Nordic competitor

Nuuka and Explore start on the same home turf. They disagree about who should touch the controls.

Anyone researching a Nuuka alternative is often someone who already trusts a Nordic vendor over a global one, and that instinct isn't wrong. Founded in Helsinki in 2012, Nuuka won the City of Helsinki's 2018 tender to monitor energy and water across roughly 1,000 municipal buildings, with a reference list including YIT, NCC, Varma, and the cities of Oulu and Lappeenranta. The product is three modules: Optimizer, Diagnostics, and Analytics, and claimed savings of 10 to 30%, vendor-published.

The boundary is who's allowed to act. Nuuka's Optimizer writes directly into your building management system, the same closed-loop control model BrainBox AI and Kiona Edge run. FrostLogic Explore reads your BMS, meters, and IoT sensors and hands your team a ranked queue; it never writes a command back. Two more things to weigh. Nuuka is a small company, fewer than 20 employees in 2026 company profiles, which can mean a responsive team or a roadmap that follows its largest shareholder. And its compliance story is annual GRESB and GRI data compilation, not continuous tracking against BREEAM, LEED, or Nordic Swan criteria between submissions. Azure-hosted, no published EU residency or data-export commitment. If you manage a portfolio rather than one building, Explore's vendor-neutral read of every BMS is built for that from day one.

Head to head

FrostLogic Explore and Nuuka, and who each one is actually for.

FrostLogic Explore

Best for teams that want a Nordic-grade energy read without handing the building's controls to software

Explore is ours, so read this entry knowing that. It runs six anomaly-detection methods with causal filtering, forecasts every tracked metric one hour to seven days ahead with confidence bounds, and tracks BREEAM, LEED, and Nordic Swan criteria continuously rather than at audit time. Hosting is in the EU on Hetzner or in your own cluster, with a direct Nordic team, and your data and trained models are exportable from day one. Read-only, always.

The boundary: Explore never writes a command to your equipment. If you want a system that adjusts HVAC on its own, Nuuka, below, already does it.

Nuuka

Best for Finnish and Nordic portfolios that want proven local references and don't mind the system writing its own commands

Founded in Helsinki in 2012, Nuuka won the City of Helsinki's 2018 tender and now monitors roughly 1,000 municipal buildings, with a reference list including YIT, NCC, Varma, and the cities of Oulu and Lappeenranta. Nuuka AI is three modules: Optimizer writes HVAC commands back every one to five minutes, up to 44,000 times a month; Diagnostics raises fault alerts; Analytics tracks 200+ KPIs. Claimed savings run 10 to 30%, vendor-published.

The boundary is control and scale. The Optimizer acts without a person approving each change. The company is small, fewer than 20 employees in 2026 company profiles. Compliance support compiles data for annual GRESB and GRI submissions rather than tracking certification criteria continuously. Azure-hosted, no published EU residency or data-export commitment, quote-only pricing.

Before you shortlist

Five questions that settle Nuuka vs Explore faster than any comparison.

Ask these on the first call with either vendor, including us. The field narrows itself fast.

  1. Do you want the system writing commands, or recommending them? Nuuka's Optimizer adjusts HVAC directly, up to 44,000 times a month, with no approval step. Explore ranks what to fix and lets your team decide. Match the choice to how much control you're willing to hand over.

  2. Does the vendor's size match the length of contract you're signing? Nuuka runs with fewer than 20 employees in 2026 company profiles. That can mean a responsive team, or a roadmap that bends toward its largest shareholder. Ask what happens to your integration if a key person leaves.

  3. Do you need continuous certification tracking, or annual reporting data? Nuuka's compliance support compiles data for annual GRESB and GRI submissions. It isn't published as continuous tracking against BREEAM, LEED, or Nordic Swan criteria between audits. Ask directly if that gap matters to you.

  4. Where does the data live, and can you take it with you? Nuuka is Azure-hosted with no published EU residency or data-export commitment. Explore is EU-hosted on Hetzner, or self-hosted, and your data and trained models are exportable from day one.

  5. Are you buying a platform, or feeding data into one you already read? Nuuka is its own closed system; buildings onboard onto it. Explore reads whatever BMS you already run, so adding or switching vendors later doesn't mean re-platforming.

Before you ask

Nuuka vs FrostLogic Explore, the questions we get.

If you want proven Nordic references and don't mind the system writing its own HVAC commands, Nuuka is a strong, close-to-home pick, and we say so plainly. If you want the human to stay the one who decides, or you manage a multi-vendor BMS estate, Explore reads further without touching your controls.

Nuuka's Optimizer writes HVAC commands back into the building every one to five minutes, closed-loop. Explore reads your BMS, meters, and IoT sensors and hands your team a ranked queue; it never writes to your controls. Explore also forecasts ahead and tracks certification criteria continuously, where Nuuka's compliance support compiles data for annual submissions.

Both platforms watch a building constantly and both are Nordic-minded. The difference is who acts. Nuuka's AI adjusts equipment directly. Explore's AI recommends, and your team makes the call.

Nuuka is Azure-hosted with no published EU data-residency commitment, though the company itself is Finnish. FrostLogic Explore is EU-hosted on Hetzner, or self-hosted, and built GDPR-native.

Nuuka is quote-only, with no published pricing we could find. FrostLogic Explore is also priced per building, on request.

BrainBox AI and Kiona Edge take the same autonomous-control route as Nuuka. Clockworks Analytics stops at HVAC diagnosis, and Facilio wraps energy analytics inside a much broader CMMS. Our best building energy management software comparison covers the full roundup.
