Laboratory Testing Services for Household Energy Devices

Berkeley Air’s laboratory testing service provides independent, timely, and accurate performance data on cookstoves, fuels, lighting devices, and other household energy appliances used in the developing world. Laboratory testing is a critical building block for many sector initiatives, including commercial scale-up, ISO standards, national product labeling schemes, humanitarian initiatives, institutional procurement, and social investment.

Independence: While Berkeley Air’s mission includes broadly supporting the growth of cleaner and more efficient household energy, we do not promote any technology, appliance, fuel, or implementation approach. Further, we commit to disclosing any potential conflicts of interest.

Capabilities and Testing Facilities:
Testing for all ISO IWA 11:2012 metrics, including:

  • Total emissions of PM2.5 and CO
  • Indoor emissions of PM2.5 and CO
  • Efficiency/fuel use (high power thermal efficiency and low power specific consumption)
  • Safety

Additional performance metrics and measurements include:

  • Durability
  • Black and organic carbon (BC/OC)
  • Ultrafine particles and particle size distribution
  • Hydrocarbons, including methane and other emissions species, as desired
  • Fuel energy and composition

Testing protocols include the Water Boiling Test (version 4.2.4 or the modified version using the Emissions Performance Test Protocol), firepower sweep test, or customized as desired.

Testing is conducted at the state-of-the-art stove testing facilities at Colorado State University, through the Household Energy and Health Center. All testers have been fully trained and adhere to strict quality and confidentiality guidelines.

Data Quality: Data is collected using high quality, traceable instrumentation and rigorous quality control procedures.
Key features include:

  • Gravimetric system for collecting particulate matter with resolution that can distinguish performance at the highest levels.
  • Daily calibration checks of gas sensors and scales.
