HVAC-only benchmark and room-level allocation

July electricity of the installed split and cassette systems, compared apples-to-apples with HVAC-only literature benchmarks. Domestic hot water is excluded and tracked separately.

Illustrative data. Figures on this page follow the benchmark specification but the daily series and room allocation are generated/modeled from design cooling-load shares. They are not room submetering and will be replaced by live telemetry.

Method

Aggregate HVAC. €471.54 / €0.2612 per kWh = 1,805.3 kWh. Only HVAC electricity; DHW, EV, kitchen, lighting, pumps excluded.
Room share. Room design cooling load / cooled-room total (29.8 kW).
Room kWh. 1,805.3 kWh × room share.
Room intensity. Room kWh / room floor area.
Normalize. HVAC share → kWh/m²-month → kWh/m²/CDD → kWh per occupied room-night.

Next inputs: confirmed conditioned area, occupied room-nights, local cooling degree days, and live per-room compressor duty cycle, damper runtime, occupancy and comfort feedback.
