10 Effective Ways for Keeping your Home Cool

Published: 06 Sep 2023 ・ Read time: 6 mins
As the weather finally gets warmer, it's important to know how to keep your home comfortable and safe in warmer weathers - as failing to keep your home cool during 30-degree heatwaves can have a significant impact on your health and well-being.
Whether you are a homeowner, a tenant, or a business owner - our experts have compiled a list of the most effective ways we can keep our house cool, especially during the heatwaves we can expect to be seeing more of in the following years as global warming intensifies.
Let’s take a look at the most effective tricks you can utilise when deciding how to keep the house cool - most of which can be done without spending a penny!

1. Keep Blinds and Curtains Closed

Keeping curtains and blinds drawn during the day is one popular method to keep heat out. Doing this typically at the hottest part of the day is ideal, usually between 10 am – 4 pm. This will help keep the sunlight off your home, preventing additional heat.
Using different types of curtains with thicker fabric and lighter colours can have varying degrees of success at cooling other rooms in your home, depending on the sun's position. 
Thick blackout curtains can also be beneficial for blocking any gaps where sunlight can peak through or cracks around the windows. This will, therefore, prevent any cool air from escaping. 
By drawing curtains and blinds effectively in the daytime, you can also improve the efficiency of your fan or air conditioning unit, as they won’t be fighting the warm, sunny air that can quickly heat up your home.

2. Switch Off Unnecessary Lights

Turning off all unnecessary lights in unoccupied rooms and appliances when they are no longer in use can help with temperature reduction, as they can generate a significant amount of heat over time. 
When it comes to light bulbs, one way to combat this issue is to consider using LED lighting instead.
This is because traditional incandescent bulbs are highly inefficient and can give off up to 90% of their energy as heat, whereas LED bulbs will convert 90% of the energy to light, making them a much cooler option in the heat. 
In the long run, LED light bulbs use much less energy overall, making them a cost-effective lighting solution.

3. Natural Ventilation

Natural ventilation is a simple yet effective way for keeping your home cooler during the warm weather. To effectively use natural ventilation you must open windows and doors either in the early morning or late evening when the air outside is cooler.
By opening windows and doors on both opposite sides of your home is a method called cross ventilation, and it is a great way to create a refreshing breeze.
However, it is important to close windows, doors and curtains during the warmest parts of the day to prevent the heat from entering your home.

4. Utilise a Programmable Thermostat

Programmable Room Thermostats are a great option that can help regulate your the temperature of your home while lowering your energy bills.
For instance, as the name suggests, a room thermostat allows you to program the thermostat to actively decrease the temperature of any room during the day - even when you are not at home. 
This will help keep your home cool in the warmer months, and because the thermostat is programmable, you can schedule your thermostat to switch off when your home is unoccupied, which will help save on any wasted energy and money.
Smart Heating controls like the Google Nest Thermostat are a perfect example of how you can take advantage of home temperature with reliable scheduling that can all be programmed from a smartphone or tablet.

5. Humidity Management

If you live in an area near the coast or in a busy city, the humidity and precipitation may make the summer heat seem even worse. 
Humidity adds moisture to the air, and excessive levels of humidity can make us feel uncomfortable, feel hotter and could even make us feel sick. To combat this, you might want to consider using a dehumidifier - as this can help reduce the sticky atmosphere in your home. 
By investing in a dehumidifier, you will help to remove the moisture from the air and make your home feel cooler and more enjoyable.
Additionally, indoor plants act as natural dehumidifiers and are another way to keep cool. Plants such as English ivy, peace lily, and Boston Ferns will naturally absorb the extra humidity around your home, leaving us feeling more relaxed and the air much fresher.

6. Heat Pump Solution

We know that investing in a Heat Pump can be costly, however, they are a versatile and efficient system that can help you keep your home cool in the warmer months. 
An air source heat pump typically works by transferring the ambient air from outside, which passes a compressor that will heat your home. The heat pump can also work by removing heat from the indoor air to the outdoor air, effectively cooling your home and providing a consistent and comfortable climate in your living space, regardless of the outside temperature.
This is because the system won't rely on cool air from the outside, but instead, it extracts heat from the indoor air, which will affect your home's temperature. 
Additionally, a heat pump can enhance indoor air quality by filtering out pollen, dust and other airborne particles, while also extracting and maintaining optimal moisture levels in your property.

7. Paint you Home Exterior

Choosing a suitable exterior material can make a surprising amount of difference in how naturally cool your home is.
For instance, using darker paint colours will typically absorb more warmth from the sun, which can increase the temperature inside your home and could increase your monthly bills from trying to keep your home cool. 
Instead, choosing lighter-coloured walls can reflect more sunlight and absorb less heat, which will help keep your home cooler during hot summer days. There’s a reason why many countries with hotter climates utilise white painted buildings.
If you're thinking about updating the appearance of your house, opting for a lighter shade for the exterior can provide a renewed look and contribute to keeping your home cooler and more energy-efficient during the warmer months.

8. Keep Cool in the Night

When the ambient temperature rises at night, it can make us feel uncomfortable and challenging to get a good night's sleep. There is one way to help combat this…
Put your pillowcase in the freezer before bedtime, as this can give you a refreshing and cool sensation when you lay down to sleep. In fact, 22% of people advised one of the main reasons behind their latest poor night's sleep was pointed to overheating as a critical factor.
Many other simple methods can help us keep cool at night, such as filling a hot water bottle with cold water and placing it in the freezer for an hour before bedtime, using a damp cloth and running your wrists under cold water can also help cool down quickly.
In addition, wearing lightweight and breathable clothing when sleeping is recommended to help regulate your body temperature and prevent overheating. Alternatively, consider bedding made from natural fibres such as cotton or linen, which are also breathable and help keep you cool and comfortable throughout the night.

9. Landscaping Cooling Strategies 

One last effective method for cooling your home is getting creative with landscaping inspirations such as planting trees or using climbing plants like ivy or perhaps vines.
Climbing plants can grow to cover the exterior of your walls, acting as an absorbent shield for heat rays. Ivy is considered the best green wall plant for cooling buildings and reducing humidity - however, keep in mind that ivy will need to be well-maintained.
Not only can these plants provide a cooling indoor environment, but they can add a unique aesthetic to your home as well, so they are well worth considering.

10. Air Conditioning

Investing in an air conditioning unit is one of the most effective ways to keep our homes cool in warmer months, and more Brits than ever before are turning to air conditioning to keep their homes cool when heatwaves hit.
Air conditioning units won't only make us feel relaxed and comfortable, but a cooler setting will also boost our productivity and help against heat-prevented illnesses such as stroke and dehydration. It's recommended to keep an eye out for units with a high energy efficiency rating, such as the Bosch Climate 3000I range, to keep your energy bills low. 
Portable air conditioning units are another great option for a flexible cooling solution, saving on any installation costs and adding portability to your home cooling.
