If you discuss about an energy efficient house,
then the concept of passivhaus
will anyway come up. The term passivhaus has originated from Germany.
It was a part of the building standards of the country. In this type
of a house, the requirement of traditionally heating is higher in
matter of insulation and even the the windows and doors that are air
tight. The whole fabric of this type of a house consists of walls and
floors, and work by getting the heat stored with an aim to maintain
the warmth during the winter season. The passive houses also have
heat pumps as well as solar panels, which actually play a very
important role when it comes to provide the efficient forms of heat.
The prime aim with which the concept of passive
house is being built is to have a very lesser effect on the
environment and will need around 75% lesser amount of heat as
compared to a regular house. However, you also need to be aware of
the build up cost, which is actually 8% more than the costing of the
traditional houses. But besides everything else, the benefit that the
owner of the house will come across is that of the savings on the
fuel bills. In addition to everything, being the owner of such a
house, you also do not have to be worried about the carbon output
being preset at the home, because there will not be any. So, if you
think that it makes sense, go for a passivhaus
today itself.
