Insulating a house during its construction

Due to its power, air heating and high thermal insulation, it maintains an ambient temperature all year round. A house is composed of a fairly simple architecture and should be oriented south if possible to collect as much energy as possible. More informations : . The concept of passive housing was created in the 1970s after several tests and is based on German construction criteria: passive housing is more expensive to build than so-called “traditional” housing. Its price may be 20% higher, but its citizens will probably save money because of a substantial reduction in their energy costs in the long term.

Choosing to build a passive house

The construction of a passive house costs between 15 and 25% more than that of a conventional house (thermal analysis, reinforced insulation, specific carpentry, equipment adapted to heat recovery, etc.), but its structure and equipment significantly reduce energy consumption and therefore long-term related expenses. Discover : . As a result, the cost, although higher, is more economical over time. In addition, the passive house is ahead of current thermal regulations. Reselling your home will therefore be easier, as its heritage value is higher than that of the equivalent home.

What is an energy house?

An energy house is also, as its name suggests, that it consumes. In practice, this generally means that it can create its own energy in such a way as to cover both the main energy costs of these occupants (heating, hot water, auxiliaries – ventilation for example – and light) and those generated by domestic uses. With energy-efficient houses, we are not talking strictly about the energy performance to be “achieved” but rather about the “costs” to be compensated.
