Since we will probably be able to purchase a plot of land next year, we plan to have more discussions with construction companies over the coming weeks.
After reading various topics here, we are wondering what the best approach is to achieve the KFW 55 standard.
The background is that through the KFW standard, we can obtain very well-subsidized loans from the Saxon Development Bank (SAB).
Our main requirement is a controlled ventilation system, which we know from friends, and since we cannot or do not want to ventilate daily, the additional investment is worth it to us.
We honestly don’t mind whether we choose a gas condensing boiler or a ground-source heat pump; it should simply be the most cost-effective option in the overall investment package.
We are a family of four (ages 30, 30, 3, 4 weeks) and want to build around 140–150m2 (1500–1600 sq ft), including a home office for my wife. The plot is about 900m2 (9700 sq ft) and fully south-facing.
If any further information or conditions are needed, please let me know.
Thank you
Goldi

Goldi0911124 Jun 2016 13:28What are the easiest and most cost-effective ways to achieve the KfW55 standard today?
Alternatively, how can you plan your house so that it meets the above requirements in the most economical way?

toxicmolotof24 Jun 2016 13:36There is no single solution, but I believe that a mechanical ventilation system with heat recovery combined with a ground-source heat pump using a horizontal collector, a photovoltaic system, and proper insulation with calcium silicate masonry plus external thermal insulation composite systems (ETICS) can be a fundamentally good and cost-effective solution (not just on paper).

is it possible to achieve the KfW55 standard with a mechanical ventilation system with heat recovery, a solar system with a buffer tank, and a gas condensing boiler? Or rather, what else is needed to meet this standard?
Best regards

I believe this is possible. The question is how much additional investment in insulation and other measures is required to achieve the standard. That’s what my initial post (see above) is about!
