The Glass Pool — from money-burner to AI-optimized.

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.

The pool building has four loads — nobody dispatches them as one

Because nobody reads them all at once. That is exactly our layer.

Pool heating28–34 °C day and night. A slow thermal mass → also a battery you can shift load into (reference site: 3,562 kWh/K).
Dehumidification / air handlingevaporation drives the load; the reference hall already recovers 63.4 % heat — the AI harvests the rest. In the tropics this flips to cooling-dominated.
Heat-pump cascadereal seasonal COP ≈ 4–7 (not the 16–22 datasheet best point). Modulating units beat one oversized machine.
On-site PVcoupled as a controllable load (reference: 243 kWp) → driven toward near-zero grid import.

One glass-box dashboard — every value on its real register

● LIVE from an anonymized European reference aquatic center — register-level over Modbus · SunSpec, updated every ~2 min.

loading live data

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.

AI dispatch

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.

Causal chains

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.

Plant assistant (RAG)

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.

Savings — measured, then licensed

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:

LeverWhy it works
Pool as thermal batteryShift hours of heating/cooling into the water without any loss of swimmer comfort.
PV-coupled dispatchMidday sun heats water / dries air instead of being exported for cents.
Honest COP + cascadeRun the heat pumps at their real efficient point, staged, not short-cycling.
Peak shaving + BESSThe 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).

As-is → Glass Pool

The pool is the #1 controllable money-burner. We flip every lever.

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.

Register-level submetering · real example

Every pump on its own channel

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.

Filter pumps 1A · 1B · 2A

Three filtration circuits, separately metered — staged to bathing load instead of all-on.

Main circulation pump

Continuous loop; demand-controlled against occupancy and water quality.

Storage-loading & pool-heating feed

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.)
