Why Air Conditioning Is Still Uncommon in Europe｜Heatwaves, Old Buildings & Cooling Options

For decades, air conditioning was far less central to everyday life in much of Europe than in hotter parts of the world. Mild summers, building traditions shaped around winter heating, and relatively low demand for residential cooling all played a role.
That assumption is becoming harder to maintain.
Europe is now the world's fastest-warming continent. According to the Copernicus Climate Change Service, temperatures in Europe have risen by roughly 0.56°C per decade over the past 30 years — more than twice the global average.
Yet residential air conditioning remains relatively uncommon. The International Energy Agency (IEA) estimates that air-conditioning ownership in Europe is only around 20%.
This creates an unusual climate-adaptation challenge: how does a region historically designed to retain heat adapt to summers that increasingly require protection from it?
Traditional European cities face a growing challenge: buildings designed primarily for cold winters must now cope with increasingly intense summer heat.
- Europe is warming more than twice as fast as the global average.
- Only around 20% of European households own air-conditioning equipment.
- Many European homes were historically optimized for retaining heat rather than rejecting it.
- Installing conventional split AC can be more complicated in some older, rented, or protected buildings.
- Portable, window-compatible and installation-light cooling systems are becoming more relevant.
- Europe's long-term challenge is not simply installing more AC, but combining cooling with better building design and lower energy demand.
1. Europe Is Warming Faster Than the Global Average
Europe's changing relationship with air conditioning begins with the climate itself.
The European State of the Climate 2025, produced by the Copernicus Climate Change Service and the World Meteorological Organization, identifies Europe as the world's fastest-warming continent.
Over the past 30 years, European temperatures have increased by approximately 0.56°C per decade, compared with about 0.27°C per decade globally.
Europe has also warmed by roughly 2.5°C compared with pre-industrial levels.
There is no single cause. Copernicus points to a combination of factors including changing atmospheric circulation, reduced snow and ice cover, changes in solar radiation reaching the surface, declining air pollution, and Europe's geography. The rate of warming also varies considerably across the continent.
The result is that heatwaves once treated as exceptional events are becoming a much more important part of European climate planning.
2. Why Is Air Conditioning Still Uncommon in Europe?
The answer is more complicated than simply saying that Europeans do not like air conditioning.
For much of modern history, large parts of Europe simply did not experience the same sustained residential cooling demand found in regions with long, hot summers. Heating was the more important design problem.
According to the IEA, air-conditioning ownership across Europe remains around 20%. The European Environment Agency has similarly documented the historically low use of active residential cooling compared with other regions.
Three structural reasons help explain the gap
① Climate history
Many European cities developed when severe summer heat was less frequent. Residential heating therefore received far more attention than mechanical cooling.
② Buildings designed around winter
Europe's building stock includes many older structures as well as homes designed to reduce winter heat loss. Insulation itself is not inherently a summer problem — well-designed insulation can also slow heat entering a building — but buildings without adequate shading, ventilation or nighttime cooling can still accumulate significant heat during prolonged hot periods.
③ Installation can be complicated
A conventional split air conditioner normally requires an outdoor unit and building work. In rented apartments, apartment blocks, historic buildings and protected districts, modifications to a facade may require permission from a landlord, building association or local authority.
These rules vary by country, city and building. It would therefore be misleading to describe Europe as having a continent-wide ban on outdoor AC units.
Europe's low AC adoption is not caused by one regulation. Climate history, electricity and equipment costs, housing type, rental restrictions, architectural preservation rules and consumer habits can all influence whether a household installs cooling.
3. A New Cooling Market Is Emerging
As extreme heat becomes more frequent, the mismatch between European buildings and summer temperatures is creating demand for cooling systems that require less permanent modification.
This is where portable air conditioners, compact heat pumps and newer window-compatible systems become interesting.
Cooling products that minimize permanent building modifications may be particularly useful for renters and some older European homes.
One Example: Midea PortaSplit
One useful example of this shift is the Midea PortaSplit. Rather than operating like a traditional single-hose portable AC, it uses separate indoor and outdoor components connected through a thin hose.
According to Midea's official European product specifications, the system provides 3.5 kW of cooling capacity, an A++ cooling energy-efficiency rating, and a 39 dB(A) Silent Mode.
Midea also states that the standard setup does not require professional installation or drilling. That makes the design particularly relevant to homes where permanent modification is inconvenient or restricted.
This does not mean PortaSplit — or any single product — is the best solution for every European home. The more important trend is the product category itself: cooling technology is adapting to buildings that were not originally designed around conventional residential AC.
How the Main Cooling Options Differ
| Cooling Type | Main Advantage | Main Limitation | Best Suited To |
|---|---|---|---|
| Traditional Split AC | Efficient, powerful cooling | Usually requires permanent installation | Homes where installation is permitted |
| Single-unit Portable AC | Easy to move and install | Typically less efficient than split systems | Temporary or rental use |
| Portable Split / Window-Compatible System | Combines an outdoor heat exchanger with lighter installation | Window compatibility, price and storage still matter | Homes where permanent installation is difficult |
4. More Air Conditioning Is Not the Only Answer
There is an important paradox in Europe's cooling transition.
Air conditioning can protect people from dangerous indoor heat, but rapidly increasing cooling demand also raises electricity consumption and can put additional pressure on power systems during hot periods.
For that reason, the European Environment Agency argues that sustainable cooling should involve more than simply adding mechanical AC to every building.
Solutions can include:
- external shutters and solar shading;
- night ventilation where conditions allow;
- better building design and renovation;
- trees, vegetation and other urban cooling measures;
- efficient cooling equipment when active cooling is necessary; and
- renewable electricity, including solar generation that can coincide with daytime cooling demand.
The objective is not to frame air conditioning as either good or bad. It is to reduce dangerous indoor heat while minimizing the energy and environmental costs of doing so.
5. What Europe's AC Shift Tells Us About Climate Adaptation
Europe's cooling problem illustrates something larger than an appliance trend.
Climate change can expose assumptions embedded in everyday infrastructure. Buildings, transportation systems and cities were designed around historical climate conditions. When those conditions change, technology has to adapt with them.
In Europe, that adaptation may mean more air conditioning. But it may also mean redesigned buildings, better shading, smarter ventilation, urban greening and cooling products designed around the physical limitations of older housing.
That is what makes Europe's changing relationship with air conditioning worth watching: it is not simply a story about selling more appliances. It is a real-world test of how mature cities adapt when their climate changes faster than their buildings do.
Frequently Asked Questions
Why don't most European homes have air conditioning?
Historically, much of Europe had less need for residential cooling than hotter regions. Housing design, installation costs, rental arrangements, local building rules and consumer habits also contribute. The IEA estimates overall European air-conditioning ownership at around 20%.
Is outdoor air-conditioning equipment banned in Europe?
No. There is no single Europe-wide ban. Restrictions can apply to particular buildings, apartment complexes or protected historic areas, and requirements vary by jurisdiction.
Does insulation make European homes hotter in summer?
Not necessarily. Good insulation can slow heat transfer in both directions. Summer overheating depends on several factors, including solar exposure, windows, shading, ventilation, thermal mass and how long a heatwave lasts.
Will air conditioning become more common in Europe?
Cooling demand is expected to become increasingly important as heatwaves intensify. However, European climate-adaptation strategies also emphasize passive cooling, building renovation and energy-efficient cooling rather than relying on air conditioning alone.
Europe's cooling transition is a useful reminder that climate adaptation often happens in ordinary places — apartments, windows and household appliances. The technologies that succeed may not simply be the most powerful ones, but those that fit the buildings and lifestyles people already have.
