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?

I would also like to build only according to the Energy Saving Ordinance. Do you then need solar panels or not? No.
"The 2014 Energy Saving Ordinance offers a certain flexibility in the practical implementation of energy-efficient building. Basically, only a target value, the maximum primary energy demand, is specified, but not the method by which this value must be achieved. Therefore, planners and builders have the option to weigh different measures against each other in order to meet the required target value. For example, a slightly lower building insulation standard can be compensated by very efficient building services technology, or with a very good insulation concept, especially complex building services systems can be avoided."

Without an additional heat pump or similar? No regulations regarding green energy tariffs for electricity/gas?No... nothing... just as the building expert already said, purely according to the energy saving regulations...
The Energy Saving Ordinance is still quite lenient with us at the moment.
The issue is that the Renewable Energy Heat Act applies to all new buildings with a usable floor area of more than 50 m² (540 ft²). Those building new homes must heat and/or cool their houses using a proportion of solar thermal energy, wood pellets, wood chips, firewood, or environmental heat (heat pump), among other sources.
Overview of the minimum required shares of renewable energy use. Each building owner must use renewable energy only proportionally. These minimum shares depend on the energy source used:

Overview of the minimum required shares of renewable energy use. Each building owner must use renewable energy only proportionally. These minimum shares depend on the energy source used:
- solar radiation energy 15% for gas condensing boilers
- solar collector area for single-family houses 0.04 m² (0.4 ft²)
- geothermal energy 50%
- environmental heat 50%
- solid biomass 50%
- gaseous biomass 30%
- liquid biomass (bio-oil) 50%
