Place thermal insulation in the house

For a house to be energetically efficient, it is important to have good thermal insulation.

This is because, in moments of greater heat, insulation prevents the property from overheating, and in cold moments, it is a protective layer that retains the heat from the heating system.

Did you know that without roof insulation, an average of 30% of heat is lost? 25% from walls and doors, and 20% from windows.

Through thermal insulation, one avoids this loss of indoor heat and a saving in heating of about 10% in the monthly energy cost.

Switch to efficient windows.

In the same line, you can replace your windows with efficient windows that offer thermal comfort and soundproofing.  

With efficient windows, you can save on your monthly energy bill, but in the short term they require an initial investment.

To install the windows, you need to know the width and height of each window in your property, which ones you want to replace, the type of opening in each, and the orientation of the house.

Afterwards, you must choose which company you want to install. At this point, you must note that it needs to be a company registered in the CLASSE+ energy labeling system.

Request quotes from different companies and choose the one that best meets your needs in terms of energy savings, quality, and cost.  

Choose more efficient devices, such as LED lamps.

If you don't have efficient appliances at home, the energy bill can skyrocket with more extreme temperatures. In winter, with heating devices, the bill can be about 20% higher.

That's why it's important to have energy-efficient appliances, like an air conditioner that is four times more efficient than an electric heater.

In addition, you can also invest in hot water production systems, such as heat pumps, or hybrid water heaters, which can reduce more than 50% of energy when heating water.

Another way to save a lot on energy consumption is to replace house lights with LED bulbs. This is because these bulbs are more efficient, last longer, and illuminate faster. But you should still remember to turn off the lights when not in use.

All of these options may imply a higher initial investment, but the amount you ultimately save monthly on the energy bill ends up compensating in the long run.

Or choose equipment with low energy consumption.

In the case of being in the process of choosing appliances, know that, for your home to become more energy efficient, you should choose low consumption equipment.

This means that since the energy consumption of larger appliances accounts for more than 40% in a house, one should buy equipment that consumes less.

To save money every month on the energy bill, you should choose appliances with an energy class equal to or higher than A++.

5. Solar panels can offset the investment.

Also, solar panels are a great option for high initial investment, but make a home much more energy efficient.

To have an idea, the installation of solar panels reduces around 60% of consumption in a house.  

There are several options of solar panels, which can be installed in homes. Solar thermal panels convert daily solar energy into heating water accumulated in a tank, while photovoltaic solar panels capture sunlight to convert it into electrical energy for home use.
