Simple representation of the basic points

Figure 1. A simplified representation illustrating the main points of a Minergie house.

The current maximum for the weighted energy demand of a single family house is set at 38 kWh/m2 per year in the Minergie category. The weighting involves the type of energy source that is chosen to meet the heating demands. Direct solar energy is highly preferred while electricity from the grid[1] is not. More about this later.


[1] I make this distinction because electricity generated via a photovoltaic system is viewed favorably.

  1. Hi ersie

    It's possible to heat a minergie p house with heat pumps.
    You now the differences meanwhile.
    Not a passiv house ?
    The difference is a little bit more insulation.
    Insulation is the cheapest material on site.

    For our case, it is more than simply increasing the thickness of the walls. All things considered, the increase in cost is more than we can pay upfront. I've looked at many houses on the list of buildings and considering the TOTAL amount of energy used, I believe that our consumption might be similar to a larger passive house. We've also made other choices such as living within walking distance of our jobs so that we have reduced our overall energy consumption in other ways.

  3. I'm going to retract my statement in the previous comment comparing our consumption to that of a larger passive house. The passive house in question would have to be slightly more than twice the size of our house and there are not many in that category around.
