  "account": "German homeowners are facing significantly higher heating costs this winter due to surging gas and heating oil prices. To reduce costs, energy expert Carsten Herbert, also known as \"Der Energiesparkommissar\", suggests simple measures such as insulating attics, walls, and windows. According to Immowelt, 41.3% of offered residential properties are heated with gas and 17.5% with oil. Herbert estimates that insulating attic floors can save 70-250 kWh per square meter per year at a cost of €70 per square meter. Additionally, window insulation films can save 75 kWh per square meter per year at a cost of €15 per square meter.",
