Together with commercial building sectors, residential homes account for about 40% of the total energy consumption in the United States.
They are also responsible for almost 40% of the nation’s carbon emissions. One reason why it happens is because of the electricity dependence that comes from coal-burning power plants.
Since using electricity has a significant impact on the environment, more and more people consider having a passive house.
Passive House: An Overview
A passive house is an energy-efficient house. It is a construction concept that offers affordability and comfort.
Passive homes and buildings can keep a cozy interior climate without active and heating cooling systems.
In other words, homeowners living in temperate areas don’t need air conditioning units. It is made possible using an airtight building envelope and an energy recovery ventilator.
Starting from an energy-efficient house concept, many individuals in New York and other states are considering this option.
How Does A Passive House Work?
In the past years, researchers have presented several exciting ideas relevant to the efficiency of residential properties.
It includes using solar panels to cut down electricity bills and low-carbon tech to achieve a more sustainable home.
But aside from these options, achieving a passive house is more recommended. It is because it requires as little as 10% of the energy.
Meaning, you can save up to 90% of the total energy costs at your home. It is made possible through proper ventilation systems.
For instance, ventilation through cracks and joints is not enough to provide fresh indoor air. The solution is not opening the windows but an ideal ventilation system.
Although it may require you some costs to build it, you can save more money later on. A passive house has several characteristics that make it an energy-saving house. Among these traits are as follow:
#1. Airtight construction
It is essential to prevent humid outside air, especially in warmer climates. With airtight construction, you can avoid the moist room air from penetrating the home’s structure.
It is crucial since high humidity can result in moderate growth, which can pose health risks.
#2. Heavy insulation
It is vital to make an energy-efficient house to decrease the heat transfer between indoor and outdoor spaces. Heavy insulation should be wrapped around the building envelope to create highly-efficient insulation.
#3. No thermal bridges
A passive house should not have thermal bridges because they create poorly insulated walls and inefficient windows.
#4. Passive heating technology
It allows heating or cooling of the inside spaces using fresh exterior air. For instance, the cold air enters the house through the ventilation system; the warm air heats it and pushes its way out.
#5. Passive solar gains
If you are buying a home, consider the position of the house. Remember that the warmth of the sun is the primary source of a passive house.
Therefore, you need a place where you can gain from the natural source of heat. Not only that, but the size and positions of the windows should also be considered.
#6. Proper ventilation
As mentioned, an efficient central ventilation system is crucial to achieving a passive home.
There will be a conscious exchange of polluted inside air through its design, which will then be filtered, maintaining a consistent humidity level and temperature.
The Benefits of Having A Low-Energy House
Having a passive house offers a lot of attractive benefits. Not only can it make your home more energy-efficient, but it can also help the environment by saving energy.
These are just some of the reasons why many homeowners in the United States are considering this option. But aside from that, you can also gain the following benefits once you build a passive home:
#1. You Can Enjoy a Cozier And More Comfortable Home.
Building a house is an investment. Since you will spend money on its construction, why not make it worth every penny? Having a comfortable home does not depend on how expensive the materials are used for building it.
A passive house is an affordable option that can also provide you with comfort. It is possible through the thermal comfort that efficient ventilation systems create.
#2. You Can Build a High-quality House.
Passive buildings require high-quality materials. Therefore, if you have a passive home, you can guarantee quality in the materials used.
Some of the things to consider are airtight insulation and the thermal bridge free design. A high level of insulation makes sure that there are no weak spots around the house. As a result, it can prevent excessive heat losses and cold corners.
#3. Cut down your heating expenses by 90%.
If you are looking for ways to reduce your home expenses, creating a low-energy house is one of the best options. As mentioned, a passive house can help you cut down your energy costs by 90%.
If you will convert it to money, that’s a massive saving on your end. You can use it to buy other essentials or keep it for future use.
#4. Help the environment.
High performing buildings and houses contribute to CO2 emissions. But with a passive home, you can reduce the energy you are using by 90%.
It is a simple way of helping the environment fight against the worsening conditions of climate change.
#5. Reduce the risks of getting respiratory diseases.
With proper ventilation, you can get rid of dust and other pollutants that can pose risks to your health.
The right amount of humidity is also essential to prevent mold growth. You can ensure a good quality of air when you install a passive home.
Every homeowner deserves a comfortable home. Making the house cozier doesn’t necessarily require expensive materials.
There is always an affordable option that can also help you save energy costs. It is through building a passive house.
With the thermal comfort that it could bring, you can guarantee a relaxing experience, whether it is summer or winter.
Not only that, but you can also save money by cutting down your energy costs. It is a win-win solution that will not make your pockets empty.
