Looking for a DEXMA alternative? Spacewell Energy and Explore solve different jobs.

DEXMA rebranded as Spacewell Energy. It is a mature European EMS: dashboards, portfolio benchmarking, AI anomaly alerts, IPMVP M&V, and ISO 50001 reporting. FrostLogic Explore is a DEXMA alternative when you want a prioritised decision queue and permissioned BMS write-back instead of another monitoring layer. Here's where each one wins.

Why compare a Sensor Intelligence layer to a classic EMS

Spacewell Energy (formerly DEXMA) charts the portfolio. Explore ranks what to do next.

Anyone searching for a DEXMA alternative usually still means Spacewell Energy, the Barcelona-origin EMS now under the Spacewell / Nemetschek umbrella. The product is a cloud energy management system: real-time multi-utility monitoring, dashboards and reports, benchmarking against a large peer footprint, AI anomaly detection with recommendations, forecasting, utility-bill analytics, carbon tracking, IPMVP-compliant M&V with automatic baselines and EPC tracking, and ISO 50001 PDCA support. Spacewell markets 200+ hardware, BMS, and SCADA connectors and a hardware-agnostic ingest path. License tiers (Entry, Advanced, Ultimate) scale by data points. Their own materials claim 15 to 30% utility savings; that figure is Spacewell's claim, not ours.

FrostLogic Explore is built for a different day-to-day. It reads your BMS, meters, and IoT sensors and returns a ranked queue: what to fix, why, and what waiting costs, with an evidence trail back to the signal. Write access starts off; you grant BMS writes one scope at a time after review. Hosting is in the EU on Hetzner, or self-hosted. List prices are public, with a free 90-day pilot on one building. If you run a multi-site portfolio, Explore is built to read mixed BMS vendors into one queue rather than another dashboard stack. Stay on Spacewell when M&V, bill analytics, and ISO 50001 reporting are the job. Shortlist Explore when the gap is prioritised action, not more charts.

Head to head

FrostLogic Explore and Spacewell Energy, and who each one is actually for.

FrostLogic Explore

Best for teams that want a ranked decision queue with grounded evidence, not another EMS dashboard

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. Findings land as a prioritised queue with an evidence trail. Hosting is in the EU on Hetzner or in your own cluster, and your data and trained models are exportable from day one. Write access starts off; you grant them one scope at a time. AI Automation is €1,500 per building per year flat; AI Maintenance starts at €5,450 per building per year by sensor band, cheaper on a 3-year deal; Enterprise over 20 buildings is quoted. Free 90-day pilot, no start fee or hardware.

Where Explore wins: the day-to-day is a ranked queue, not charts. Grounded inference ties every finding to a signal. Permissioned BMS write-back exists after you grant a scope. Pricing and the pilot are published. Where Spacewell still wins: mature EMS analytics, IPMVP/EPC tooling, ISO 50001 reporting fit, multi-utility bill analytics, and a large European installed base that still searches under the DEXMA name.

Spacewell Energy (formerly DEXMA)

Best for EU portfolios that need EMS dashboards, M&V, benchmarking, and ISO 50001 reporting in one product

Spacewell Energy is the current brand for the platform long known as DEXMA. It is a cloud EMS aimed at portfolio energy and sustainability teams: real-time monitoring across electricity, gas, water, thermal and more, comparative benchmarking, AI anomaly detection with impact-ranked recommendations, forecasting, utility-bill analytics, carbon tracking, IPMVP M&V with automatic baselines and EPC tracking, and ISO 50001 Plan-Do-Check-Act support. Spacewell publishes 200+ connectors to meters, BMS, and SCADA, and sells Entry / Advanced / Ultimate licenses by data-point bands rather than a single public EUR list price.

Where Spacewell Energy wins: depth in classic EMS workflows, M&V and EPC tracking, ISO 50001 reporting, multi-utility coverage, and a Spanish and wider EU installed base. The boundary for Explore buyers: Spacewell is monitoring, reporting, and recommendation software. It is not a Sensor Intelligence ranked queue with permissioned write-back on the BMS you already run.

Weighing other European EMS and BEMS options too? Clockworks, BrainBox, Nuuka, Facilio, Kiona, and Myrspoven sit on the same shortlist.

Spacewell claims come from spacewell.com energy-management materials as of October 2026. "Not published" means we could not find a public EUR list price, which is not proof none exists. Spacewell's 15 to 30% utility savings figure is their marketing claim.

Before you shortlist

Five questions that settle DEXMA / Spacewell Energy 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 need M&V, bill analytics, and ISO 50001 reporting, or a ranked action queue? Spacewell Energy is built for classic EMS reporting, IPMVP M&V, and ISO 50001 workflows. Explore is built so operators open a prioritised queue with evidence, not another dashboard. Match the tool to the morning job.

  2. Is DEXMA still the product name? No. DEXMA rebranded as Spacewell Energy. Search demand still says DEXMA, especially in Spain, but you are buying Spacewell Energy under the Spacewell / Nemetschek umbrella. Ask the vendor to put the current product name and roadmap in the contract.

  3. Who controls write-back to the BMS? Explore's write access starts off; you grant scopes after review. Spacewell Energy is sold as monitoring, analytics, and recommendations. If closed-loop HVAC control is the requirement, look at BrainBox, Nuuka, Kiona, or Myrspoven instead of either of us.

  4. Can you see list pricing before a sales cycle? Explore publishes AI Automation at €1,500 per building per year and AI Maintenance from €5,450 per building per year by sensor band, with a free 90-day pilot. Spacewell publishes Entry / Advanced / Ultimate license bands by data points; ask them for current EUR quotes rather than inventing a number from a brochure.

  5. Where does the data live, and can you leave with it? Explore is EU-hosted on Hetzner or self-hosted, with exportable data and models. Spacewell is an EU-origin EMS; confirm residency, subprocessors, and exit terms in writing for your portfolio.

Before you ask

DEXMA alternative questions we get about Spacewell Energy and Explore.

Yes. DEXMA rebranded as Spacewell Energy. Buyers still search DEXMA, especially in Spanish markets, but the live product is Spacewell Energy. This page is the DEXMA alternative comparison for that product.

No. Explore is not a drop-in EMS replacement. Spacewell Energy is the monitoring, dashboard, M&V, and ISO 50001 reporting product. Explore is a Sensor Intelligence layer that returns a ranked decision queue on the BMS and meters you already run. Different job.

Explore list prices are public: AI Automation €1,500 per building per year flat; AI Maintenance from €5,450 per building per year by sensor band, cheaper on a 3-year deal; Enterprise over 20 buildings quoted; free 90-day pilot; no start fee or hardware. Spacewell sells Entry / Advanced / Ultimate by data points. We do not invent EUR list prices for them; ask Spacewell for a current quote.

Write access starts off. You grant permissioned BMS writes per scope after review. Smart Schedules exist inside a granted scope. Do not read Explore as a never-write product, and do not read it as unsupervised closed-loop HVAC control.

In the EU on Hetzner, or self-hosted in your own cluster. Data and trained models are exportable. That is a deliberate EU-buyer posture beside any EMS you keep for reporting.

Pick Spacewell Energy when utility-bill analytics, portfolio benchmarking, IPMVP M&V, EPC tracking, and ISO 50001 PDCA reporting are the primary job. Pick Explore when operators need a prioritised queue with grounded evidence and optional permissioned write-back on the systems they already run. Many estates can run both: Spacewell for EMS reporting, Explore for ranked action.

Clockworks Analytics for HVAC diagnostics, BrainBox AI or Nuuka for autonomous control, Facilio when energy sits inside a CMMS, Kiona or Myrspoven for Nordic closed-loop HVAC, and Explore when the gap is a ranked queue. Our best building energy management software comparison covers the wider shortlist. For German analytics-plus-control, see our aedifion alternative comparison.
