A resort pool burns money around the clock — yet its huge thermal mass makes it an ideal battery for PV, storage and cooling. In four steps we make its heating, dehumidification, heat pumps and PV observable, then let one AI run them. Proven on a real European aquatic center; licensed worldwide by Stromfee.US.

● LIVE from an anonymized European reference aquatic center — register-level over Modbus · SunSpec, updated every ~2 min.
Live values are metered at an anonymized European municipal aquatic center (same plant, presented anonymously). Constants (heat-recovery 63.4 %, COP band 4–7, 243 kWp) are metered/engineered from that site. Your property gets its own live glass-box fed by your plant. Prices shown are EU reference (EPEX); US sites are baselined on your ISO/LMP.

One brain schedules heating, dehumidification and heat pumps against PV, weather and price — using the pool itself as thermal storage. Near-zero grid import instead of low-value export.

Data-driven cause→effect for every anomaly (why did the COP drop, why did the peak spike) — the same causal engine that runs on the reference plant.

Ask your plant's own documentation in plain language — grounded on your real registers and manuals, not a generic chatbot. Honest numbers, no black box.
Every saved kWh is proven against your measured baseline. If it isn't measured, we don't claim it. Honest levers on a pool building:
| Lever | Why it works |
|---|---|
| Pool as thermal battery | Shift hours of heating/cooling into the water without any loss of swimmer comfort. |
| PV-coupled dispatch | Midday sun heats water / dries air instead of being exported for cents. |
| Honest COP + cascade | Run the heat pumps at their real efficient point, staged, not short-cycling. |
| Peak shaving + BESS | The steady 24/7 pool base load makes storage arbitrage and peak shaving pay. |
The reference site: ~570,000 kWh electricity + 1.29 GWh gas per year — the scale where these levers move real money. Tropical resorts: the method transfers, the kilowatt-hours are measured on your plant first (no invented tropical numbers).
Same plant, two states: the as-is (how it runs today, from the existing plant/GLT documentation) vs the Glass Pool (AI-optimized, from high-end engineering). Universal — the transformation is the same in every climate; only setpoints change.
| System | As-is — money-burner | The Glass Pool — AI |
|---|---|---|
| Heat pumps | sold on datasheet COP 16–22; one oversized unit short-cycling | real seasonal COP 4–7, modulating cascade |
| Air handling | heat-recovery untuned, dehumidification runs flat-out | 63.4 % WRG actively harvested |
| On-site PV | surplus exported for cents | coupled as load → near-zero grid import |
| Pool water | passive heat sink | thermal battery 3,562 kWh/K — load-shifted |
| Backwash water | heat dumped to drain | ≈ 290 kWh/day recovered (hybrid source) |
| Control | siloed, reactive, black-box | one AI, register-level, causal-chain diagnosed |
As-is = existing-plant / GLT documentation (RAG). Glass Pool = high-end engineering concept. Both from one real European aquatic reference; presented anonymously. Same method as our glass BESS, biogas plant and CHP.
Pool circulation is a 24/7 base load — the classic silent money-burner. At the reference site each circuit is metered individually on a 6-channel meter, so the AI runs each pump on demand (VFD) instead of flat-out.
Three filtration circuits, separately metered — staged to bathing load instead of all-on.
Continuous loop; demand-controlled against occupancy and water quality.
Charged into the pool thermal battery during PV surplus / cheap hours.
Real 6-channel register-level submetering at the reference site. (Live pump feed shown only when the submeter is online — honest by design: no stale zeros dressed up as live.)
Understand → Live → AI (causal chains) → Value, per trade — the same method as our glass BESS, biogas plant and CHP. Live where metered, honest design values otherwise.
