Passive construction is today a hot item in the house . But if we examine the conditions for passive building further, and we compare it with energy efficient building or AM (almost energy neutral) , what can we conclude? In this article Econ Housing deeper into this equation.
We are not architects here among themselves and so it is to make things understandable intention.
It is primarily on three basic principles we should apply stricter and stricter in the construction of a new home.
- Airtight finish
- Ventilation with heat recovery
These three building principles we can all use. This is simply a matter of DO.
The next two principles, however, we do not have in hand.
- compact build
- use winter
These depend on the size of the plot and the location to the south.
On a long narrow plot or less, it is not possible to build compact. I always give the example of a single-storey house of 100 sqm. Either we build this compact 10 m to 10 m. This gives 40 m outside. We may have to deviate because of the plot width and we therefore 5m 20m from. A bit extreme but it shows the importance of compact build.
With the same 100 sqm living space we have 50m exterior needed. This means that our outside of the home, called building shell, 30 sqm increases.
If now the location to the south front is on the street side, we also lose the opportunity to fully enjoy the warmth of the winter sun. Large windows on the south side and small windows on the north side are hard to fit in.
We speak of a passive house, if all five principles are applied. So say all of our houses are passive houses , can not . A well-known passive builder has already experienced this firsthand. Only 1 in 5 has been certified as a passive house.
That is why we prefer to talk about E 30 home, an AM (almost energy neutral) property or a low energy house. Before construction starts have an energy study done so that we can determine in advance how far we go with the application of the abovementioned principles.
