What is a passive house?
A passive house is a house that consumes little energy while remaining thermally comfortable. Partially or completely autonomous, the structure, orientation, thermal insulation and waterproofing of the passive house maximize solar radiation in order to meet the heating needs of the home in winter. A passive house consumes on average four times less energy than a traditional house.
Why choose passive construction?
Ecological, economical in the long term and aesthetic, embarking on passive construction is also making the choice of conscience and responsibility. The houses Passive Certified took off in India in the 2000s and is born and the desire to reduce the greenhouse effect by the energy independence of the habitat.
The certification:
To meet standards, a real passive house must meet four criteria which correspond to very precise energy results. Certification involves validating the design of your passive house and calculating its consumption, followed by an air tightness test and monitoring of consumption. Watch out for scams! A simple statement is not enough, beware of false advertising…
Insulation of a passive house:
Keeping a home warm – or cool, if necessary – is no small task, and for that it is a question of particularly well insulating the walls. The main heat losses occur when heat passes through wall walls. The roof is the first element to take into account since the hot air rises, but the walls and floors are not to be neglected either.
Doors and windows – transparent and open able – must have special coverings and joinery. The use of double or triple glazing is therefore strongly recommended or even necessary in order to guarantee a sufficient level of insulation. Particular attention must also be paid to the elimination of “thermal bridges” because they constitute passages favoring heat loss. Insulation from the outside must therefore be preferred to avoid these bridges and guarantee a pleasant ambient temperature inside the house. Ventilation of a passive building:
A passive building must therefore, to avoid heat loss, reduce any air passage as much as possible.
The ventilation inlets are therefore the only points allowing the passage of air. In general, passive houses have dual-flow ventilation with filtering, which gives these buildings excellent indoor air quality.

The waterproofing of the passive house envelope:
Like insulation, waterproofing is absolutely essential when it comes to passive construction. The house envelope must be perfectly waterproof in order to withstand bad weather and promote satisfactory thermal comfort for the inhabitants of the house, in all seasons.
Recovery of the outgoing heat:
When the insulation of a house is satisfactory, however, it becomes an important channel of heat loss. In a traditional house, ventilation draws in the outside air to reject it outside after passing through the hot zone. But in a passive house, there is no question of heating this incoming air to evacuate the heat to the outside, the heat is therefore recovered from the outgoing air to heat the incoming air. We say goodbye to the frozen air in winter!
Passive houses, bio climatic houses. What are the differences ?
You are probably wondering what the differences are between a passive house and a bio climatic house. Well, if a bio climatic house is not necessarily passive, its design is nevertheless developed and adapted to its environment in order to obtain the maximum of energy resources.
A bio climatic house thus represents the basis for achieving a passive building but is not necessarily certified or autonomous. For example, a bio climatic house can take many forms: yurt, tepee, earthen dwelling, and wooden cabin, so many Eco-conscious constructions that do not meet strict standards but which are nonetheless partially or completely off-grid.
And how much does a passive house cost?
The cost of building a passive house is a little higher than that of a normal house. However, if you consider all the energy costs that you will save after your installation, you definitely come out a winner! Turnkey, the price of a single story passive house construction will cost you at least between 1300 and 30000 rupees per square meter excluding air and water, while the price per square meter of a brick house is between 10000 and 18000 rupees per square meter.
Keep in mind that if you want to build a two-story house, you will pay around 10-15% more! These prices are obviously given as an indication and can vary enormously depending on the nature of your project and its size! Are you interested in these passive houses?
