The construction of passive houses has emerged as one of the most important goals. That we must accomplish if we are going to be able to make the most efficient use of the limited resources. Which are available on the planet. We offer best services and construction of best quality passive houses at Contracting Companies in Dubai.
Before just a few short years ago, the construction of classic houses did not place a significant emphasis on preserving the homes’ original characteristics. That would make the house more comfortable while at the same time lowering the amount of energy that consume.
Because of the rise in the price of fossil fuels like gas, oil, and coal, this has been gradually shifting in a more positive direction.
In light of the current state of the world, it is imperative that we reevaluate the kind of homes we envision for ourselves and the means by which we intend to make them a reality.
In this piece, we will provide you with an in-depth discussion on passive houses, including the ways in which they are beneficial to both people and the environment, as well as the requirements for constructing a home that has a low overall energy footprint.
Passive House Operation
According to various statistics, 35% of the energy lost in a building is through electrical installations.
Sealing them means nothing more than dedicating some time and specific materials developed for this purpose.
This implies the absence of cracks, holes, or any type of hole in which the outside air enters in any condition.
The correct execution of the hermeticity control by means of a test carries out that in the construction, the Blower Door, with which we make sure that the renovations per hour are less than the maximum foreseen by the standard and that, as we have already said, it is 0, 6 r/h with a pressure difference of 50 pascals.
Controlled Ventilation
Directly related to the previous point, we find controlled ventilation. Keep in mind that opening the windows does not guarantee proper ventilation.
It can ventilate in excess and be cooling the walls, which leads to higher energy consumption. Or, on the other hand, it can ventilate by default, so the indoor air quality will not be adequate.
In addition, it is known that the quality of outdoor air does not have to be always good, since for various reasons it contains a large number of substances in suspension.
Here, the standard proposed by Passivhaus is a mechanical ventilation system with heat recovery.
Said system exchanges the energy of the interior air, which we have heated, with that of the fresh air that enters the system cold, thus ensuring that the energy that has cost us money does not expel to the outside when ventilating and that the air that we introduce in our home have a more suitable temperature.
Design Free of Thermal Bridges
Thermal bridges are zones or points in which the transmittance of modifies the constructive solution, worsening it, which is why the amount of energy that passes through these points in increase the façade, through which both transmit cold and heat. It easily transmits and accesses the interior of the home through, for example, conductive elements such as metal.
In this case, for passive houses, we recommend the elimination of thermal bridges, or failing that, the application of materials to prevent this transfer.
You have to take great care of the encounters between materials and use and apply good seals so that there are no leaks.
Location, Weather and Other Options
Apart from these characteristics, there are also some design constraints which directly affect the home.
The first of these is the place where the house is going to build and the physical constraints to which it will subject, for example, altitude and weather conditions, shadows cast on the building, etc.
Placement Of Passive Houses
The location and vegetation is important since the house will be exposed to a certain climate.
On the other hand, the solar orientation of the house will also be key.
This orientation will be taken into account to take advantage of all the light and energy possible for our home.
Depending also on the meteorological agents, it will be convenient to choose colors that do not absorb heat as much as white in hot places, and vice versa.
On the other hand, if the place is very hot in summer, different measures will take so that the heat does not enter the house.
For example, a good formula is to have deciduous trees that offer shade and provide coolness in summer periods, but in winter they lose their leaves and let in the light and heat of the sun.
Small great sustainable and practical options that will increase the efficiency of our passive house.
Materials Needed to Get a Passive House
Although the Passivehaus standard does not establish or indicate what type of materials must apply in a passive house, we will indicate some to achieve a house with these characteristics.
Apart from the technicians you will need to design your home, you will require a series of fundamental construction materials to make your home efficient and comfortable.
To achieve this purpose, you will need quality materials and a good application of them.
Here we indicate a small list with some of the construction elements necessary to carry out your project.
Thermal Insulation
There are many thermal insulators. Fiberglass, polystyrene, rock wool, wood fiber, etc.
Many options are good, however, if we have to recommend one, we will stick with wood fiber.
This thermal insulation makes from natural elements, usually grinding fir wood, and then subjected to mechanical pressing processes and added some products to improve its qualities.
Wood Fiber Installed on The Wall
Despite make of wood, it is fire resistant. In addition, it has great thermal and acoustic properties.
This insulation is a small regulator of temperature (and humidity, absorbing it when there is an excess and providing it when there is a deficit).
In addition, it is a sustainable and ecological material, which is why we believe that it is the most suitable for a passive house.
Quality Doors and Windows
If roof windows or balcony windows and doors are going to include in your design, without a doubt the best option for this element is the velux windows.
Balcony Windows
This brand creates specialized solutions with the highest quality to ensure sealing and airtightness in frames and enclosure structures.
However, the return on investment will cover in approximately 5-10 years, so it is a worthwhile cost.
Conclusion
Being aware of the point at which we are and wanting to build a passive and efficient home in which the most polluting resources are the last option, will not only provide us with great savings in energy costs, but will also make us have a more comfortable home.
Even so, if for whatever reason you cannot get into a construction with these characteristics, you can always carry out some of its standards to make your home gradually more passive.
