Scope. EG-COOL, powered by ESLIA's inverter technology, currently applies to split units and standalone package AC units. Centralized and VRF cooling systems are not yet supported. Boilers, chillers, and compressors serving cold rooms / cold storage are outside the scope of this technology entirely.

Baseline Cooling Load — Choose a Method
Itemizing is the more defensible number for a proposal. The bill-based estimate is a fast first pass for early-stage prospecting — use it to gauge whether a site is worth a full walkthrough, not as the number you'd put in a client-facing report.
Estimate AC Load from TNB Bill History
Upload the client's TNB bills as PDF — 12 separate files, or one combined PDF. The tool reads the text layer of each bill (no OCR needed for digital e-bills) and pulls out the billing month and kWh. Rows are editable if extraction misses something.
Drop or choose TNB bill PDF(s)
PDF reader didn't load. This can happen if the network path to cdnjs is blocked in this environment. Use "+ Add month" below to type in bills by hand instead — everything downstream still works from manual entries.

Working assumption, not a verified figure. 42% is used here as a working estimate for the air-conditioning-specific share of a typical commercial electricity bill. Actual AC share varies by building type, usage pattern, and equipment age — this figure is a starting point for a quick estimate, not a substitute for an actual site assessment. Adjust the % above if you have a better estimate for your building.
Add every split-unit or standalone package AC unit at this site. Quick-add presets below are pre-filtered to eligible equipment only — boiler/chiller/cold-room items are outside this technology's scope, and centralized/VRF systems are not yet supported.
Two ways to size a unit: enter its nameplate Watts directly, or switch a row to HP mode to use ESLIA's published HP-based methodology — HP × kWh factor × hours. The kWh factor below (0.75 kW drawn per HP) reflects ESLIA's standard assumption across unit tiers.

EG-COOL Savings & Payback
How the 27% figure is set. This tool caps assumed savings at 27% — verified performance data: SIRIM Berhad ETRC Report ref R374/22 (J177/22, August 2022), ISO 14034:2016 ETV methodology, tested on a single inverter split unit at ESLIA's own premises. ESLIA's own published figures for individual HP tiers range 20–25%, comfortably under this cap. Figures shown below are indicative estimates based on published equipment specifications — final pricing and savings are confirmed during a free on-site assessment.
27%
The 27% figure was tested on a single inverter split unit — not a clinic ward, cold room, or manufacturing floor. Treat it as an upper-bound reference figure, not a guaranteed outcome for your specific site. A free on-site assessment gives you a figure specific to your building.
12-Month Savings & Payback Schedule
Flat monthly projection at the assumed saving % above — no seasonality applied, since neither the SIRIM report nor ESLIA's sheet models month-to-month variation. Treat as an even-spread estimate, not a forecast of any specific month.
Same 27%-capped saving % applied per unit type, so you can quote an individual unit's expected monthly saving rather than only the site total.
