What-if Energy Lab

Compare a baseline household with an optimized scenario and watch the estimates update live.

Simulation only. The Lab compares a captured baseline with an optimized scenario. Slider changes never overwrite the baseline — re-capture it after editing appliances on the dashboard.

Baseline scenario

No snapshot captured yet — your current household configuration is serving as the baseline.

Baseline total: 270.00 kWh/month · ৳2,700.00/month

Optimized scenario

Adjust each appliance's simulated runtime and ON/OFF state. Baseline values stay fixed.

Fan

Baseline: 8.00 h/day · 75 W · ON

Optimized runtime: 8.00 h/day

Air conditioner (AC)

Baseline: 6.00 h/day · 1000 W · ON

Optimized runtime: 6.00 h/day

Lights

Baseline: 5.00 h/day · 60 W · ON

Optimized runtime: 5.00 h/day

Refrigerator

Baseline: 8.00 h/day · 150 W · ON

Optimized runtime: 8.00 h/day

Television (TV)

Baseline: 4.00 h/day · 100 W · ON

Optimized runtime: 4.00 h/day

Washing machine

Baseline: 1.00 h/day · 500 W · ON

Optimized runtime: 1.00 h/day

No estimated change

The optimized scenario currently matches the baseline. Move a slider or turn something OFF.

Baseline vs optimized — monthly energy

kWh/month per appliance, from your captured baseline and scenario sliders

Household total: 270.00 kWh baseline vs 270.00 kWh optimized.

Savings goal

Your target (the “Goal”) is separate from the calculated “Estimated savings”. Only positive estimated savings count toward progress — a cost increase never does.

Top 3 energy-saving opportunities

Ranked by estimated potential cost savings — the effect of running each ON appliance one hour/day less, bounded by its current runtime. Estimates, not guaranteed reductions.

1
Reducing Air conditioner (AC) by 1.00 hour/day (from 6.00 h/day) could save an estimated ৳300.00/month at your configured tariff.
2
Reducing Washing machine by 1.00 hour/day (from 1.00 h/day) could save an estimated ৳150.00/month at your configured tariff.
3
Reducing Refrigerator by 1.00 hour/day (from 8.00 h/day) could save an estimated ৳45.00/month at your configured tariff.
