A concept that has revolutionized sustainable buildings based on renewable energy and little impact on the environment, the company that offers the waste removal service shares with us its information. They are buildings that are committed to long-term sustainable development. It is known as a passive house. Translated into Spanish it is like a passive house and refers to a type of house construction that has unique characteristics.
In the field of development of modern architecture based on renewable energies and the use of natural resources, this new concept was born. A passive house is nothing more than a type of house that refers to a building standard of a house that meets certain characteristics. These features are as follows:
- It is efficient in energy consumption. For this, the principles of bioclimatic architecture are used to be able to take advantage of all the energy conditions that exist in the environment to reduce energy consumption.
- It should be cosy and comfortable. Energy efficiency gained through a precise location and environmental energy should not reduce the quality of life.
- It should be affordable for almost everyone and not just a few.
- Ecological In addition to energy efficiency, it must be built respecting and reducing the impact on the environment and perfectly integrated with its environment. During the use of this house, the impacts on the environment should be reduced as much as possible.
In this way, we make a Passive House a place that can consume minimal energy while maintaining suitable air conditioning conditions throughout the year. The construction, design and arrangement of all materials are completely ecological to minimize the carbon footprint and other impacts on the environment.
The origin of the passive house
This concept is not about a brand, but about an efficient construction concept. It appeared for the first time at the beginning of the decade of the 80s. Since that time, more and more people talk about bioclimatic architecture to be able to build houses. The first thing that must be done to be able to build a bioclimatic house is to know to study the climate of the area where it will be built. Here you have to take into account the days of sun, and rain, the environment that surrounds it, the distance to supply the areas, etc. In this way, it is possible to take advantage of all these variables to the maximum to decide whether the right orientation and design to reduce energy consumption and have better living conditions.
All the above is added to the use of different materials and construction procedures that use ecological and efficient techniques for the environment that have been studied before. In this way, it is possible to build a house that has a very low energy consumption and a low impact on the environment.
We can say that the concept of the passive house goes beyond what is thought when it comes to talking about energy rating labels on buildings. These energy efficiency labels on buildings indeed reveal a lot of information about it. It can tell us the amount of energy the building consumes as a whole and the energy efficiency it has. However, He does not speak about the pattern and materials with which the house was built.
Savings in energy consumption with a passive house
Let’s see what savings we can have when we build a Passive House. To get an idea, we are talking about all the standards that this type of construction follows and that can help us save on the following:
- Savings up to 90% in heating consumption. This value is given if we compare it with other buildings that have followed traditional construction models.
- We can get savings of up to 75% or more on heating by buying this passive house with newly built buildings that have the highest efficiency standards.
- If our area has a mild climate, it is where the greatest expenditure of energy is spent on cooling and not heating. All of this has been proven in similar consumer savings data.
Let’s see what are the main advantages of the passive house:
- A radical reduction in the energy bill. This means savings in the medium and long term.
- Responsible and environmentally friendly energy consumption.
- Lower environmental impact in all phases of the life of this house, from its construction to the end of its useful life.
- Greater comfort and better quality of life. This is necessary since all air conditioning is constantly controlled. In this way, we achieve an environment that has basic and constant conditions more comfortable than any other type of home.
- More useful life and less expenditure on repairs and reforms. This passive house employs various state-of-the-art technologies with high-end materials. Being more sophisticated and environmentally friendly materials, they last much longer. In addition, it has the advantage that it does not require so many repairs and there are no other problems arising from the use of low quality in construction.
Design and construction of the passive house
Let’s see what are some of the features that this construction standard has.
- Excellent thermal insulation: given the building that has high energy efficiency with low consumption and an excellent guarantee of comfort. Thermal energy is optimized through good insulation and is useful both in winter and summer.
- Facades, external walls, roofs and thresholds are built with a material with a low level of thermal transmissibility.
- High-performance windows and doors: Most conventional forces have a weak point which is gaps. In its correct setting during work, this space can be reduced to transmit less heat.
- Absence of thermal bridges: energy transmission occurs continuously both in facades, roofs and tiles. It can also be found in corners and edges.
- Air tightness: the house is as tight as possible as much as the maximum execution of joints during construction.
- Mechanical ventilation with heat recovery: requires heat recovery ventilation to reuse the indoor air temperature and preheat or cool the fresh air.
