Under the USAID-funded WASHplus project (primarily led by FHI-360 and Winrock International), Berkeley Air conducted two technical sub-studies to compare five improved wood-burning cookstoves to the traditional cookstove. The improved stoves included Envirofit Z3000, Prakti Chimney Stove, Eco Chula, Greenway Smart Stove, and EcoZoom Dura. A qualitative household survey was administered to evaluate the users’ perceptions, needs, and willingness to pay. Cookstove fuel efficiency and usage was measured using the Kitchen Performance Test (KPT) protocol in 140 homes and temperature-logging stove-use monitors in a subset of the homes. The other sub-study collected preliminary data on kitchen concentrations and exposure of cooks and children to air pollution (CO, PM_2.5) to assess feasibility of several health-related indicators. In addition to field support, Berkeley Air also led a two-day training session for field workers, local NGOs, and small stove manufacturers.
