Nowadays we are very aware of the environment and energy saving, this is translating into architecture in looking for systems that lead us to achieve these goals in our homes. To talk about Passivhaus is to talk about a construction philosophy based mainly on doing things well and minimizing the energy consumption of homes by improving their comfort.
This term is nothing new, it emerged in the late eighties, with the first building built under this standard arriving in 1990 in Germany.
This standard is gaining ground both in single-family UAE Email List homes and in blocks of flats, offices, etc. The objective is to achieve minimum energy costs with maximum quality of life, it is more than just creating a low-consumption building:
Passivhaus homes achieve energy savings of up to 60% compared to homes built under Spanish regulations.
They make efficient use of the sun, taking advantage of it both to illuminate and heat it.
The interior temperature is very stable, avoiding temperature jumps between rooms.
They are equipped with ventilation systems that recover heat from the air it extracts and gives the home top quality air at all times.
Very tight homes are made without condensation problems, without air leaks, gaining in comfort and indoor air quality.
We have many reasons to build a home under this standard; optimal air quality by using ventilation systems with filters and heat recoverers, thereby keeping a home free of pollen, mites, dust, etc…; we reach optimal thermal comfort, without thermal jumps between rooms; use of sunlight, both for heat and lighting gains, allowing with an appropriate design to reduce the use of artificial light for a large part of the day and all reflected in great energy savings, for this, high-quality insulation is placed. quality avoiding thermal bridges by carrying out a thorough study of each one of them.
Finally, we must address the cost of building a home of this type. It is undeniable that building a Passivhaus home is more expensive than a home with traditional systems. Certain studies place the increase compared to the latter between 10% and 15%. % , but we should analyze the energy savings that this home represents during its useful life (around 60% savings in heating and cooling systems) in addition to enjoying a much higher quality of life.
In any case, I would like to reflect on this last point, it is clear that seen this way it would be a greater initial investment that could be profitable in 8 or 10 years, it would be like buying a luxury car instead of a utility vehicle and thinking that as the years go by The cost of the luxury car would be lower than the other, perhaps so, but in the society we live in, a large part of people do not have that initial investment so they would settle for accessing the utility vehicle. That is to say, it is not convenient to generalize and want all the homes built in our country to be Passivehaus or to have an A energy rating, this type of home has its demand and represents a great advance in improving construction quality, but it is no less It is true that there is still more demand for affordable housing from young people and people with less income, and this demand should not be nullified by laws or regulations that, although they force us to improve many technical aspects of housing, on the other hand make the cost of housing more expensive. a good that is of first necessity for everyone.
We can always choose, depending on our income, whether or not to turn on the heating, air conditioning, and even open the windows ten minutes a day to ventilate, as we learned from our grandmothers. After all, let's think about our country, how much time a year do we have the windows of our house open despite in many cases having so many construction advances.
