Strategies for maintaining a cool German home without the need for air conditioning
In the heart of Europe, Germany is known for its rich history, efficient infrastructure, and traditional building designs. However, when it comes to air conditioning in homes, the landscape is a bit more complex.
Renters in Germany need permission from their landlords to install air conditioning units, as landlords are legally required to ensure minimum indoor temperatures in winter but not maximum temperatures in summer. This means that tenants generally do not have a guaranteed right to have air conditioning installed.
When it comes to the installation of air conditioning units, there are rules and restrictions to consider, especially in old homes or historic areas. While Germany, as part of the EU, follows EU-wide regulations such as the F-gas Regulation and the Ecodesign Directive, these focus on environmental sustainability and energy efficiency rather than installation permissions. They encourage the use of climate-friendly cooling agents and energy-efficient split systems and generally promote other heat mitigation methods like better insulation and shading.
Local restrictions and permits also play a significant role. While no general national ban exists, in some historic or architecturally sensitive areas, local heritage preservation laws or aesthetic regulations may restrict or prohibit external AC units to preserve building appearance. In some European cities, permits may be required for AC installation, sometimes needing to prove medical necessity, although such strict permitting is more common in other European countries than documented explicitly for Germany.
Cultural and market factors also contribute to the low adoption of air conditioning in Germany. There is still resistance towards air conditioning, partly due to environmental concerns, energy costs, and traditional building designs that rely on passive cooling. Installing AC is often considered a luxury rather than a necessity.
Despite these challenges, some homeowners are turning to energy-efficient solutions like heat pumps, which can keep a home cool in the summer as well as warm in the winter. Heat pumps may save money in the long term due to low running costs, but they are not a cheap initial investment. Grants are available to help residents of Germany install heat pumps.
In the pursuit of keeping homes cool during summer, other strategies include good insulation, strategic ventilation, keeping outdoor spaces shaded, and using fans to circulate air. Simple measures like closing blinds or curtains, planting leafy plants to block sunlight, and placing a bowl of ice or a cool damp towel in front of a fan can also help.
In 2023, only 13 percent of German households had air conditioning, and this number increased to 19 percent in 2024. As the climate continues to change and summers become hotter, it remains to be seen whether the cultural resistance towards air conditioning will soften, and more homes will be equipped with cooling systems.

- Although Germany is recognized for its traditional building designs, some tenants may find it challenging to install air conditioning units due to landlord permissions and restrictions, especially in historic or architecturally sensitive areas.
- In contrast to the EU-wide regulations focusing on environmental sustainability and energy efficiency, local permits and heritage preservation laws can significantly affect the installation of air conditioning units in Germany, potentially restricting or prohibiting the use of exterior units to maintain the building's appearance.
