Monitoring Indoor Climate Extremes with Citizen Science and IoT Approaches

This webinar explored how extreme heat affects residents living in uninsulated low-cost dwellings in the Cities of Ekurhuleni and Tshwane. Drawing on action research undertaken by Planact in partnership with the Flemish Institute for Technological Research (VITO), and with the support of Enabel, the Belgian Development Cooperation Agency, the webinar that took place on the 7 October 2026, shared evidence and lessons from indoor heat monitoring, examine how building materials, housing characteristics and environmental conditions influence indoor temperatures, and discussed innovative approaches to creating more resilient, climate-responsive settlements through sustainable building materials, appropriate technologies and adaptation responses.
