Radon is a radioactive gas that has a natural origin. It is common for it to accumulate in indoor spaces, such as homes, offices, or any other. When constructing a home, it is necessary to assess the exposure to radon gas that the building may experience and install a mechanical ventilation system to prevent the concentration of this gas in the home if necessary.

The energy certificate is a document that is essential for both selling and renting a property. This document includes the energy consumption and CO2 emissions of the property in question. In Spain, it has been mandatory since June 1, 2013, and is regulated by Royal Decree 235/2013. Furthermore, this certificate originates from a European Directive to which all member states have already joined. Next, we show you how to obtain the Energy Efficiency Certificate with mechanical ventilation.

• How to obtain the Energy Efficiency Certificate with mechanical ventilation in compliance with regulations?

To know which regulations apply to the property, it is necessary to consider whether it is a residence or a commercial premises, as they are different.

When it comes to a residence, the document that regulates ventilation is the Basic Document HS3, Basic Health Requirements, from the Technical Building Code CTE.

For commercial premises with a use other than housing, the regulation that is taken into account for ventilation is the RITE, the Regulations for Thermal Installations in Buildings. It appears in the section dedicated to interior quality, where the minimum provisions you must include are marked in order to ensure thermal comfort and hygiene through heating, air conditioning, and sanitary hot water installations. The aim is for energy to be used rationally.

Depending on the condition of the premises, it will be necessary to choose one ventilation system or another, but it must always be ensured that the air quality is adequate and that air circulates within the premises efficiently. The mechanical ventilation is the best option, but there can also be other alternatives such as hybrid or natural systems. When it works correctly, it ensures that the premises are free of smoke, chemical pollutants, or any other substance that could harm the health of workers.

It must also be ensured that the quality of the air entering from the outside is adequate, and for this purpose, it will be necessary to have filters or similar elements so that the air that enters is as pure as possible.

To obtain the Energy Efficiency Certificate with mechanical ventilation it must be verified that the installations are correct and functioning properly.

• What should different buildings meet to obtain the Energy Efficiency Certificate with mechanical ventilation?

The Energy Efficiency Certificate is an official document that is mandatory for all properties that are to be sold or rented. Although interpreting the scale values is not difficult, as it is a value from A to G and has a series of colors from green to red for better understanding, how to calculate the energy rating scale is more complicated. The reason is that a process of calculations is needed that are quite complex, involving specific indices and intervals.

Sometimes, determining the entry points of radon gas inside buildings, even knowing that it mainly comes from the ground, is not easy. In this case, we can observe a house built on a slope, whose lowest floor was completely buried by one of its main facades.

If there is anything that the pandemic has helped us to manifest, it is the importance of ventilation in the fight against the pandemic, eliminating contaminated air in enclosed spaces and sanitizing our interiors. From the beginning, the use of masks, maintaining social distance, or hand washing has been promoted. But as we have learned more about the virus and its contagion, one measure has gained ground due to its proven effectiveness in preventing contagion: proper ventilation of enclosed spaces. In the following lines, we explain the...

Sick Building Syndrome 😿 What is it? It is an illness recognized by the World Health Organization (WHO) and is the cause of a set of discomforts arising from poor ventilation and temperature decomposition, among other factors, which produces a series of very varied symptoms.

Filters: the great allies to reduce pollution levels. The WHO states that by reducing pollution levels, strokes, lung cancers, and chronic and acute respiratory diseases, such as asthma, can be reduced.

The quality of indoor air is closely related to the comfort perception of the people occupying them, as we have described in detail in this article on our blog.

Many users wonder what HVAC actually refers to, which is the types of air conditioning systems. It is an acronym that is increasingly used in the air conditioning sector. Here we want to explain precisely what it means and which aspects this term encompasses.

The air quality in indoor spaces has gained special relevance over the last few years. However, there are many other pollutants that can negatively affect our health. Therefore, at Siber, we want to talk about the importance of ventilation to achieve adequate levels.
