I currently live in a studio with my partner. We have a project in the more or less near future to build our own little nest. We both have an ecological fiber and we would like to participate in our own way to a better life on the planet.
We were thinking of building a house of more or less 150m². We would like to do things correctly and therefore we would like to plan and arrange everything when designing the house. We live in Belgium: in Walloon Brabant to be precise.
I have heard of a passive house (do you have any information? Costs, specifications, air circulation system, ...). Which almost does not require heating, however, I read that it was better to have extra heating to compensate for the very cold day and certain types of climate. The cities I visited advocated the use of an auxiliary electric convector or gas heating, but this did not run counter to an ecological process. Is it true? What are the possible solutions. For my part, I was thinking of a heat pump. Is it achievable? isn't it too expensive? What is the price of such an installation? Are there 2 types of heating with the pump by the floor or by convector? What is the best? Does the heat pump allow to heat domestic water (for shower, bath, ...)? Do we have to add solar panels and / or a solar boiler to produce hot water?
We also wanted to produce our own electricity, we had thought of 30M2 of photovoltaic panels ... Is that enough?
Do you have any other suggestions? What would be the price of such an installation in a house? Do you have any ideas for subsidies received for these systems in Belgium? Is all this profitable? What would be the depreciation period for such an installation? What is the lifespan of the different elements?
Good day to you
Sébastien
