Kitchen Performance Tests (KPTs) are field-based procedures that measure and validate real-world fuel consumption in household cooking environments through direct observation. These tests follow strict methodological requirements to ensure accurate quantification of emission reductions and prevent over-crediting.

Components

Household Registration

Register and randomly select households following protocol requirements

Data Collection

Record daily fuel consumption with minimum 3-day observation period

Verification

Validate KPT results against protocols and control group data

Credentials

Issue verifiable KPT credentials with emission reduction data

​

​
Integration Examples

​
Combining with IoT Data and Control Groups

# Get KPT baseline for both groups
reference_baseline = client.kpt.get_baseline("reference-group")
intervention_baseline = client.kpt.get_baseline("intervention-group")

# Compare with IoT readings
iot_data = client.devices.get_usage("device-456")
reduction = calculate_reduction(reference_baseline, intervention_baseline, iot_data)

# Validate seasonal factors
seasonal_impact = client.kpt.analyze_seasonal_variations(reduction)

Always ensure compliance with minimum 3-day testing period and proper control group implementation.
