Knowing about energy consumption is key to being able to save on the electricity bill. Before buying a home it is necessary to attend to a series of criteria to avoid expenses, although many people do not pay due importance to them.
As we know that you would all like to pay less, today we come to provide you with a little more information on a topic that may interest you. In this case we will explain what are the passive houses and what are its pillars.
What is a passive house?
In the construction world, the terms of passive or active to indicate the degree of absence or presence of artificial systems to condition a home.
The fewer machines needed, the more passive the house in question will be. Of course, we must emphasize that a passive house will always need some energy, not doing it is extremely complicated and utopian.
Before getting to the heart of the matter, we also have to distinguish between the energy required to condition the house for thermal and light comfort and the energy to use electrical appliances. The passive house concept refers, almost entirely, to the first group.
In short, a passive house would have to have good lighting and temperature without using almost any energy. The theory is easy to understand, but how do you go about it?
The solar heat and light they are essential to make a passive house a reality. With that in mind, as a homeowner you should size the windows according to the light that enters your house both in winter and in summer.
Of course, these factors will vary depending on where your home is and the climate in your city. You will also have to know aspects such as wind and assess the use of pergolas, awnings, etc.
If you want to have a passive house you will have to try to have any passive system that allows us to control humidity, interior light or temperature. Here are some examples:
- Water sources
- Direct contact with the earth
- Green roofs
This is another aspect that many forget when choosing their home. However, the truth is that using one or other construction materials can be of great relevance to control temperature or humidity.
In places where it is very hot, they are often used materials with inertia for thermal control, while in cold climates the wood usually works better. Let's not forget about the lime, capable of regulating humidity in a totally natural way.
Similarly, it might be interesting to have ceiling fans, since they serve to reduce the thermal sensation a few degrees. Of course, it would take some added energy, so it would not be natural, as in the previous examples.
Passive house, active user
That said, anyone who wants to have a passive house must be clear that it requires the active user attitude. If not, you will not be able to do it.
Do you want to ventilate? You have to go open the window. Do you want the heat to stay? You have to close the doors. And so we could go on to infinity. So, you decide, it is only up to you to start enjoying the advantages of a passive house.
