Malta’s Homes Struggle with Hotter Nights

As the sun sets on a sweltering summer day in Malta, residents are finding it increasingly difficult to cool down. The once-cozy homes that have served us well through the mild Maltese winters are now struggling to cope with the rising temperatures, leaving many residents tossing and turning in the stifling heat. But why is this happening, and what can we do about it?

Malta’s Changing Climate

Malta, like the rest of the world, is experiencing the effects of climate change. According to the Malta Meteorological Office, the average temperature in Malta has risen by 1.1°C over the past century. While this might not sound like much, it’s enough to make a significant difference to our summers. Nights that were once cool and refreshing are now often uncomfortably warm, with temperatures frequently exceeding 25°C.

This increase in night-time temperatures, known as the ‘urban heat island effect’, is exacerbated by Malta’s urban scene. Concrete and asphalt absorb heat during the day and release it at night, making cities like Valletta and Birkirkara feel significantly warmer than their rural counterparts. This is particularly noticeable in the narrow, densely-built streets of the Three Cities, where the lack of breeze can make the nights feel even hotter.

Homes Built for Winter, Not Summer

Many of Malta’s homes were built with the mild Maltese winter in mind, not the hotter summers we’re now experiencing. Traditional Maltese houses, with their thick stone walls and small windows, were designed to keep out the cold and provide shade from the sun. However, these same features now trap heat, making our homes feel like ovens on hot summer nights.

many Maltese homes lack basic features that could help to keep them cool, such as insulation, double glazing, and air conditioning. According to a survey by the Energy and Water Agency, only 16% of Maltese households have air conditioning, compared to the European average of 50%. This lack of cooling systems, combined with the heat-trapping design of many Maltese homes, leaves residents sweating through the summer nights.

What Can We Do?

So, what can we do to make our homes more comfortable in the face of hotter summers? The good news is that there are plenty of simple, affordable steps we can take to cool down our homes and reduce our energy bills.

One of the most effective ways to cool down a home is to keep it shaded during the day. This can be as simple as closing curtains or installing external shading devices like awnings or shutters. The Energy and Water Agency’s ‘Cool Roofs’ initiative also encourages homeowners to paint their roofs white or install reflective materials, which can reduce the temperature of a roof by up to 30°C.

Insulation is another key way to keep homes cool in the summer and warm in the winter. The Energy and Water Agency offers grants to homeowners to install insulation in their homes, which can significantly reduce energy bills and improve comfort.

Air conditioning is another option, but it’s important to choose energy-efficient models and use them sparingly to avoid contributing to the problem of climate change. Ceiling fans can also be an effective way to cool down a room, using far less energy than air conditioning.

But it’s not just about individual actions. The government also has a role to play in helping Malta’s homes cope with hotter summers. This could involve incentivizing homeowners to make energy-efficient renovations, investing in public cooling spaces like fountains and green areas, and implementing policies to reduce Malta’s carbon emissions.

As Malta continues to warm, it’s clear that we need to adapt our homes and our habits to cope with the changing climate. By working together, we can make our homes more comfortable and sustainable, and ensure that we’re ready to face whatever the future holds.
