These days, it’s not difficult to make your home energy-efficient. When you buy a home larger than 50^m2, you’ll be eligible for its Energy Efficiency Certificate, which will provide you with valuable information about the energy consumption and demand of the building where it is located. In some cases, you may even have access to other certificates, such as Quartz and Jade from CULMIA, which will detail all the sustainability and health measures implemented during its construction.

And, for those cases where there’s still work to be done in this area, we can always take matters into our own hands and implement measures to make the most of energy in our homes. In fact, it can be very easy to do, so in this article we’re sharing 10 ideas for creating an energy-efficient home. Are you ready to put them into practice starting today?

Tips for Creating an Energy-Efficient Home

Ensure that your home is properly insulated

What is energy efficiency all about? It’s very simple: it’s about finding ways to make the best possible use of energy. The goal is to optimize our home’s energy consumption so that we can live comfortably, while minimizing energy loss in the process.

It is estimated that up to 99% of homes in Spain suffer from some form of energy loss, which is usually “due” to inadequate insulation. Not surprisingly, of the total energy lost, most of it usually escapes through the roof (25–30%) and the walls (25–30%), in addition to the windows (20–25%) and the floors (10–15%).

These four areas are the key spots in our home that we need to monitor to prevent heat loss. And if we notice that heat is escaping, we should take action: installing thermal insulation underlayment or wooden flooring, adding insulation (polystyrene, mineral wool, EPS panels, etc.) to walls and ceilings, and choosing double-pane and eliminating thermal bridges or using thermal paint for decoration.

If we do this successfully, we’ll be able to save up to 40% on our electricity bill.

Proper ventilation

Ventilation is necessary in any home because it allows for air renewal, eliminates odors, and disperses airborne particles that may be harmful to health. However, natural ventilation has the drawback of causing energy loss, because energy escapes when windows are opened.

Given this choice, we can opt for the installation of a hybrid ventilation system or a controlled mechanical system. The former combines natural ventilation with a mechanism for forced ventilation via mechanical exhaust, depending on the climate and the pressure it detects. The latter, however, does not require natural ventilation, as the system itself includes air intake and exhaust mechanisms that draw air from outside, regulate the necessary airflow, and filter it to ensure optimal air quality.

Energy-efficient lighting

Lighting can account for nearly 12% of a home’s total energy consumption, so the first step toward making your home more energy-efficient in this area is to replace traditional light bulbs with energy-efficient ones. And there are compelling reasons to do so, because these bulbs can save nearly 80% compared to their traditional counterparts, in addition to lasting up to eight times longer.

A great way to achieve great results with your home lighting is to opt for LED solutions. These stand out for being more efficient than traditional solutions, as well as more sustainable, environmentally friendly, and long-lasting.

Climate Control: Optimal Temperature

To create an energy-efficient home, you don’t have to sacrifice your comfort or that of your family. At CULMIA, we know how important it is for you to always enjoy the perfect temperature, and that’s why we have some good news for you: today, there are fully sustainable climate control options available.

Given that the better a home is insulated, the less energy it will require to heat it in the winter or cool it in the summer, we can consider installing climate control systems that utilize renewable energy. We’re referring, for example, to options such as air-source heat pumps, ground-source heat pumps, or biomass boilers.

And if these solutions don’t appeal to us or can’t be properly installed in our home, we can also consider optimizing the energy used by more traditional heating systems, such as those that run on natural gas or diesel. In these cases, one option is to install underfloor heating, since this system is routed beneath the floor and allows us to cool or heat the surface we walk on to regulate the temperature of our home.

Self-Consumption and Renewable Energy

Do we want access to clean, affordable energy? Let’s choose to “produce” it ourselves. There are currently programs and initiatives at both the state and local levels that promote and incentivize energy self-consumption in the home through the installation of solar panels or even wind turbines.

Of course, it’s unlikely that we’ll be able to produce all the energy our home needs using only solar or wind power, but even as a supplemental energy source, it can end up being economically viable in the medium and long term, as well as very beneficial for the environment.

Home automation

Technology can also help us use energy efficiently at home. If we have a smart home, we’ll be able to better manage our energy consumption and schedule the operation of appliances and key components that regulate energy and heat, such as blinds or air conditioning.

What’s more, according to the Spanish Association of Home Automation ( CEDOM), the use of smart control and automation tools and technologies can help us save up to 30% on our home’s energy consumption. How? By always keeping the air conditioner at an optimal temperature, turning lights on or off at the right times, turning off appliances at specific times or when they’re not in use, and so on.

Energy-efficient appliances

Washing machine, dryer, dishwasher, TV, iron, stereo…there can be many appliances in a home. And although we often hardly even bother to check their energy consumption before buying them, doing so should make it much easier for us to achieve an energy-efficient home.

It is no surprise, then, that household appliances are the second-largest source of energy consumption in the home, trailing only heating and ahead of hot water, cooking, lighting, and air conditioning.

Fortunately, since January 1, 2021, we’ve had a label-based rating system (from A to G, from most efficient to least) that provides information about a product’s energy efficiency right on the packaging. This can undoubtedly help us make the best decisions when shopping.

Putting the 3 “R”s into Practice

Efficiency is also achieved by limiting the energy, products, and materials we use. To do this, we can follow the 3 “R” rule: that is, reduce consumption, reuse, and recycle. In this way, thanks to the circular economy, we’ll get more out of products, extend their useful life, and contribute to a more sustainable world.

Hot Water Notice

As we just mentioned, heating water requires more energy than cooking, lighting the home, or heating or cooling the rooms. That’s why there are several options for keeping water at an optimal temperature: electric water heaters, gas water heaters, solar panels, air-source heat pumps…

Every system has its pros and cons, so it’s best to learn in detail what each one has to offer and, based on the characteristics and possibilities of our home, choose the option that is most efficient and practical.

Be efficient even in the small details

Finally, to make our homes more energy-efficient , we can also do our part every day by adopting sustainable behaviors and habits. There are actually many ways to do this, such as unplugging appliances when we’re not using them, running the dishwasher and washing machine only when they’re completely full, taking showers instead of baths, turning off the faucet while brushing our teeth, or turning off the lights when we leave a room.

The thing is… in order to get the most out of an energy-efficient home, it’s essential that we also adopt a lifestyle committed to protecting the environment!
