Everyone has their own version of a dream home, but despite the differences, there are a few characteristics that all dream homes share. These characteristics would be the following: comfortable, modern house with no cold drafts, no temperature variations from room to room, and — most important of all — no heating or cooling bills. In other words, everyone just wants a house that is both comfortable and ecological — studies have shown that.
Right now, people would think that it’s impossible to have a house that has all these characteristics. They would say that that kind of house is totally just fantasy. But in actuality, it’s totally possible to have this kind of house in our current world. In fact, these ideal comfortable conditions are what people experience when they live in passive houses.
What Is A Passive House?
Simply put, a passive house is a construction concept and a building standard that is truly energy-efficient, comfortable, affordable, and ecological. It is heated primarily by the sun, but unlike houses that use solar panels (sometimes solar roof shingles) to generate electricity, a passive house also makes use of the sun’s heat. And with the design and construction of the passive house, the interior climate can be maintained without active heating and cooling systems.
The first passive house was reported to have been built in Darmstadt, Germany back in 1991. Technically, even in the 1970s and 1980s, there were already houses that employed a somewhat passive solar design to collect heat from the sun. But it was only in the 1990s when designers took that idea and made it even better by adding superior insulation, airtight construction, energy-efficient windows, and carefully controlled ventilation. In other words, it was only in the 1990s when the passive house standard was born.
What Are The Benefits of A Passive House?
Comfort
As you can see from the characteristics of a passive house, comfort is obviously one of the primary goals of this design. The climate inside the house will be exactly what you want it to be, without the use of heating and cooling systems. So, in other words, even if the weather outside is too cold or too hot, you’ll still be snug and comfortable inside your house.
Quality
Passive houses incorporate a high level of insulation and airtight design, and for that, they are constantly praised. Additionally, passive houses implement the “thermal bridge free design,” which means that insulation is applied without any “weak spots” around the whole building. The primary purpose of this principle is to eliminate cold corners and excessive heat losses. With this quality, it is no wonder that the comfort of passive houses is unmatched.
Energy Efficient
The design of passive houses allows them to be highly energy efficient. In fact, passive houses have the potential to use up to 90% less energy than the current building stock while still performing the same functions as traditional buildings. Sometimes even, passive houses can perform way better.
Basically, with the design of passive houses, fuel bills will be significantly lower because of the reduced energy consumption. This would then be extremely beneficial to the end-user since they can save money as well as help to alleviate fuel poverty.
Eco-Friendliness
From the definition of a passive house, you can tell that it is definitely eco-friendly. After all, it uses natural energy from the sun, so it only uses little primary energy. And using only little primary energy will definitely leave sufficient energy resources for all future generations without causing any significant harm to the environment. So, basically, building a passive house is definitely one way to help protect our environment.
Affordability
In the long run, passive houses will definitely save you money, but aside from that, they are actually affordable in the first place. It is a surprising fact, but it is a fact all the same. The investment in higher quality building components required by the Passive House Standard is reduced by the elimination of expensive heating and cooling systems. Plus, many countries offer additional financial support, thus making it more feasible to build passive houses.
Versatility
The Passive House Standard is suitable for all kinds of buildings and in all kinds of climate zones. That would then mean that any competent architect out there can definitely design a passive house.
Because of the versatility of this kind of structure design, the utilization of the Passive House Standard has gone beyond the residential buildings. Before, only residential houses made use of this standard, but right now, other kinds of buildings have started to implement this too. You can definitely see so many schools, office buildings, factories, and even swimming pools that made use of the Passive House Standard. With this, you can definitely say without a doubt that this standard has no limitations on construction methods or materials. In other words, the Passive House Standard is, indeed, versatile.
Takeaway
A person’s dream house can vary from someone else’s in terms of aesthetic details and size, but differences aside, everyone’s dream houses fit the Passive House Standard. The Passive House Standard refers to the building standard that is truly energy-efficient, comfortable, affordable, and ecological at the same time. Buildings with this kind of standard are cozy, with no cold drafts, no temperature variations, and no heating or cooling bills. In other words, passive houses make for a comfortable living space, thus making them the ideal place to live.
The Passive House Standard has only come to be recognized quite recently, but it’s definitely getting a lot of traction nowadays. And why shouldn’t it be? It boasts a number of benefits for the end-user, such as comfort, quality, and affordability, and it is also a perfect way to help save the environment. With the benefits that the Passive House Standard offers, it should be no surprise anymore if, in the near future, most of the buildings constructed will follow that standard.
