In a passive house, thermal insulation is done with high-quality materials so as to eliminate any heat loss points such as walls, floors and roof. Another important element is to avoid thermal bridges, so as to prevent heat transfer through building elements that are not properly insulated, such as windows or doors.
A passive house must meet certain standards for thermal insulation. For example, for walls, the heat transfer coefficient (U-value) must be less than 0.15 W/m2K, and for the roof and floor, the U-value must be less than 0.10 W/m2K.
“Thermal insulation in a passive house not only helps to save energy, but also creates a comfortable and healthy environment in your home.”
By using adequate thermal insulation in a passive house, up to 90% of the energy needed for heating or cooling can be saved, compared to a regular house. Also, such a house contributes to protecting the environment by reducing CO2 emissions.
In conclusion, thermal insulation is a crucial element in the construction of a passive house. It is important to use quality materials and avoid thermal bridges in order to ensure a comfortable and energy efficient environment inside the house.
The use of renewable energy in a passive house
A passive house is not only an energy-efficient building, it can also become a source of renewable energy . By using clean energy sources such as solar panels or a geothermal system, you can further reduce your energy consumption and greenhouse gas emissions.
An advantage of using renewable energy is that these energy sources are free and environmentally friendly. You can also benefit from intelligent energy storage systems, so excess energy can be saved and used later.
Using solar panels in a passive house
Solar panels are a great way to use solar energy to power your home. They can be mounted on the roof of the house and used to produce electricity or heat.
As technology develops, solar panels are becoming more efficient and affordable. In addition, they require little maintenance and have a long lifespan. By using solar panels, you can significantly reduce electricity costs and help reduce greenhouse gas emissions.
Using a geothermal system in a passive house
A geothermal system uses the earth’s natural heat to heat or cool a home. This system involves an underground pipe dug to such a depth that the temperature of the earth is constant.
Thus, the geothermal system provides heating or cooling efficiently and can be used in combination with other renewable energy sources. Although initial installation costs can be high, geothermal can be a great long-term option as it can significantly lower your energy bills and help reduce greenhouse gas emissions.
The process of building a passive house
To ensure a green and energy-efficient construction, the construction process of a passive house requires attention and planning at every stage. Starting with the design and continuing with the construction and installation of the systems, every step is important to achieve the desired level of energy efficiency.
When it comes to design, it is important to consider the orientation of the house and the positioning of the windows according to the path of the sun. Thus, the use of solar energy can be maximized and the need for artificial heating or cooling can be reduced. It is also important to choose the right materials for insulation and thermal efficiency.
An essential stage in the construction of a passive house is the installation of a protective barrier against water vapor and air, using materials such as polymer membrane or polyurethane foam boards. This barrier ensures that the ideal temperature is maintained inside the house, reducing the need for artificial heating or cooling.
The installation of ventilation and heating and cooling systems also plays an important role in creating an energy efficient passive house. It is recommended to use a ventilation system with heat recovery, which reduces energy losses and contributes to energy savings.
“The process of building a passive house requires attention and planning at every stage.”
The design of a passive house
The design of a passive house has a crucial role in its thermal efficiency. It must be built in such a way as to take advantage of natural light as much as possible and to minimize heat loss.
An important aspect is the orientation of the house. It should be built to capture as much sunlight as possible in the winter and be shielded from it in the summer. Windows should also be placed to maximize consideration of the orientation of the house.
Building materials also play an important role in the design of a passive house. For example, thermal insulation and air tightness are essential to reduce heat loss. Also, construction materials should be sustainable, environmentally friendly and recyclable as far as possible.
“The design of a passive house must be carefully thought out to ensure thermal efficiency and optimal indoor comfort.”
The ventilation system in a passive house
To ensure optimal energy efficiency in a passive house, it is essential to have an adequate ventilation system.
This system has the role of maintaining a constant flow of fresh and healthy air inside the house, without affecting energy efficiency.
Unlike traditional houses, which can have large heat losses through opening windows or doors, a passive house uses a ventilation system with heat recovery to maintain thermal comfort.
This system uses the air from outside to heat or cool the air inside, depending on the needs, without losing the thermal energy stored in the house.
For this reason, an adequate ventilation system is vital for the energy efficiency of the passive house, providing comfort without compromising energy savings.
Humidity control in a passive house
In a passive house, another important aspect is indoor humidity control.
Due to the high thermal insulation, there is a risk of condensation accumulating on cold surfaces inside the house, causing humidity and air quality problems.
An adequate ventilation system is designed to maintain the optimal level of humidity inside the passive house, which is essential for the health of the inhabitants and the maintenance of air quality.
Maintenance and costs of a passive house
One of the biggest concerns for homeowners is the cost of maintenance. With a passive house, long-term costs are significantly reduced due to energy savings and energy efficiency. Traditionally, an average house consumes large amounts of heat and electricity, leading to higher costs for the homeowner.
A passive house, on the other hand, is designed to minimize heat loss and reduce electricity consumption. This means that the owner will spend much less on energy bills. In addition to saving electricity, a passive house typically uses heating and cooling systems that are much more energy efficient, thus also reducing long-term costs for the homeowner.
In addition, although the initial construction costs are higher than those of a typical house, the costs pay off in the long run due to the savings realized by the owner. In general, a passive house has an initial cost of 10-20% more than a traditional house, but the owner can save between 80-90% on energy costs in the long term.
Certification of a passive house
