ᐅ New single-family house construction with a gas heating system, but without solar panels

Hello everyone,

I have already searched on Google, but I couldn’t find a suitable answer for our specific project.

In short: We want to build a single-family house. It will have a gas heating system, but I want to avoid solar panels, heat pumps, or other alternatives (please don’t question the reasoning behind this).

Here are some key details:
- Single-family house, about 153m² (1646 sq ft) of living space on 2 full floors plus a full basement
- 365 mm (14.4 inch) exterior wall, T10 bricks, possibly T9 bricks
- No KfW funding!
- decentralized ventilation system with heat recovery
- wood stove on the ground floor

Of course, I know that the Energy Act (EEnG) requires a certain percentage of energy consumption to come from renewable sources.

My question is: Under the above conditions, is it sufficient to simply choose an eco-friendly gas tariff from the energy supplier, allowing me to avoid installing solar panels, additional insulation, heat pumps, or similar measures? Or is it mandatory to install solar panels on the roof?

You need to specify the type of heating system...

Well, now I am really surprised?!?!

We are planning a T8 MW 36.5, no chimney, no mechanical ventilation with heat recovery, triple-glazed windows, and the attic will be insulated.

Without an additional heat pump or similar?
No regulations regarding eco-tariffs for electricity/gas?

Basti2709 is building strictly according to the Energy Saving Ordinance and not additionally following the "yxz" efficiency house standard; it seems you are overlooking this in your discussion.

However, this will only work until March 31, 2016, after which it will no longer be valid.

I would also prefer to build only according to the Energy Saving Ordinance. Does that mean solar panels are required or not?
