ᐅ Mechanical ventilation with heat recovery instead of solar thermal energy?

Hello,
We are planning a new build that will be heated with a natural gas boiler, and we would like to install a mechanical ventilation system with heat recovery.
For natural gas heating, regulations require that 15% of the heating demand must be covered by “renewable energy.” Is it possible to meet this requirement with a mechanical ventilation system, thereby possibly avoiding the need for solar thermal panels on the roof?
Has anyone had experience with this? Would such a system even qualify as “renewable energy”? After all, heating costs are reduced, although the electricity demand increases slightly...
Thanks in advance.

Yes, it is, but with additional expenses elsewhere.If the extra costs are cheaper than the €6000 (about $6500) for solar, then it would be okay. Since we are building a flat roof, solar panels don’t really suit my plans anyway.

- Gas condensing boiler
- Controlled mechanical ventilation system
According to our architect’s calculations, solar thermal energy can be omitted.
