Domestic Renewable Energies applicable in Building

know what types of renewable energy are applicable in the field of construction represents a fundamental advance in the fight against climate change.

Domestic Renewable Energies applicable in Building

Energy conservation has become a priority worldwide. Reduce our energy consumption and opt for alternative sources with less environmental impact.

Next, we present the 5 main sources of renewable energy applicable to construction and the domestic sphere.

Solar energy


The use of the electromagnetic radiation from the sun is one of the most widespread and recognized forms of renewable energy use, especially appropriate for regions such as Spain.

Its use dates back even to the seventh century BC, when our ancestors began to use the sun’s rays together with magnifying glasses to produce fire. Today the techniques for its use have been perfected to the point of even being able to to stock this energy produced.

There are different methods of using solar energy, namely: passive, photovoltaic or thermal.

Passive Solar Energy: bioclimatic architecture

The passive solar technology encompasses all those techniques in which sunlight takes advantage of natural form for immediate usewithout having to transform it.

It is, for example, the orientation of the constructions or the use of thick walls that ensure adequate thermal insulation during the different seasons of the year.

Its application to building design gives rise to the bioclimatic architecture. In this, it is the construction elements themselves that absorb energy during daylight hours to be able to take advantage of it at night.

Photovoltaic Solar Energy

The Photovoltaic Solar Energy responds to the use of solar panels as part of the design and construction of the building, replacing facades or skylights. These are configured as a key source of electricity.

These panels work from the so-called “photovoltaic effect”. When solar radiation strikes one of the faces of the photoelectric cells that compose them, a potential difference is generated that causes the electrons to jump from one place to another. This movement of electrons generates the electric current.

It is a source inexhaustible Y non-polluting for whose installation there are numerous grants and subsidies, summarized here.

Thermal solar energy

This third option consists of taking advantage of solar energy to generate heat. It is generally used in the production of Hot water for domestic use, for example for showers, heating or air conditioning of swimming pools. This heat can also be used to produce cooling and air conditioning in buildings.

Small wind energy


The small wind power It is consolidated as an interesting option for building. Its installation requires little work and can produce energy without the need for strong winds, despite withstanding winds of up to 200km/h

The system is capable of producing up to 70% of the electricity consumption of an average home, and the designs of mini wind turbines are becoming more and more aesthetic.

It is an ideal system for individual homes or small communities. Also, certain versions like the “hive” wind turbines for facades They facilitate their installation in buildings. This makes the most of the available space.



The biomassorganic matter originating from biological processesis another source of energy in buildings that is gradually gaining a relevant position among the most used.

It is an energy source of high efficiency. The CO2 released by plants in their decomposition process approaches null values ​​when considering the amount that they have absorbed during their growth.

There are several types of biomass, such as residual generated in human activities, that coming from surpluses agricultural or the one that comes from energy crops. In this other item We tell you in detail everything about this energy source.



These systems allow the extraction of energy in the form of heat stored under the earth’s surface. Between the advantages of geothermal compared to other renewable sources, such as solar or wind, is the being constantbeing available at all hours for 365 days a year.

Although its extraction price is lower than that of other clean energies, it requires a certain investment in exploration to find the ideal terrain.

Its uses are similar to those of solar thermal energy, from the production of domestic hot watereven systems of heating with heat-cold pumps or underfloor heating.



The last of the renewable energies applicable to the building that we present, is the aerothermal. This allows the production of energy by harnessing the heat contained in the air. For this purpose they are used aerothermal heat pumps.

This method does not involve CO2 emissions, as it does not require combustion. In addition, it can lead to a 70% savings compared to traditional heating systems, such as gas or electricity.

The technology results easy and quick to installand has a easy maintenance as it does not require cleaning. Another advantage of aerothermal energy is the use of a single generator to heat or cool the environment and produce domestic hot water.

It requires a small initial investment that is recovered approximately in a period of 3 to 5 years.

Spain and Renewable Energies

In 2019, Spain reached a record figure of renewable energy generation capacity. To date, these clean energies constitute 52% of installed energy in the country.

Even so, there are many buildings that still depend on traditional energy sources to meet their needs.

We are still far from Iceland, the leading country in clean energy with 85% of its energy expenditure coming from renewable sources.

If you want to join the change and switch to clean energy, don’t hesitate to ask for budget to our professionals.
