Homes where indoor temperatures can reach an unbearable 38 degrees Celsius, bedrooms that don’t cool down even at night and residents who limit air-conditioning use because they can’t afford to have it running for hours: This is the picture of summer energy poverty in our country, as depicted in the report “Homes in a Climate Crisis.”
Produced by Greenpeace’s Greek branch with support from the European Climate Foundation, the report is based on field research conducted by the Passive House Institute.
Kathimerini presents the findings of the study, which examined living conditions in 29 homes across various building types in six different regions (Athens, Thessaloniki, Larissa and Kalambaka in central Greece; Iraklio and Hania in Crete; Kozani in the north; and Patra in the west) – covering all of the country’s climate zones – during July and August 2025.
By gathering sensor data on key factors such as temperature, humidity and indoor air quality from these homes, the study reveals the extent of summer energy poverty and how it disproportionately impacts vulnerable populations across Greece.
