FreddyBaum9 Apr 2014 10:06Hello,
I have a basic question:
What is the most energy-efficient way to build my house?
Thank you in advance.

Could this possibly be a bit more specific?

Hello,
By reducing the actual demand for heating and domestic hot water! However, to do this, you first need to know the demand.
For heating alone, this essentially means minimizing heat losses through the building envelope and ventilation (demand). Ultimately, this leads to something like a Passive House standard. Whether this is economically viable in each specific case is a completely different matter. ;-)
The system must achieve a high seasonal performance factor (SPF), or for heat pumps, a correspondingly high annual performance factor.
This requires proper planning, sizing, and design of all components!
For improvements beyond the legally required minimum standards (energy saving regulations / building codes), there are various funding programs that can partially offset the additional investment costs, but they do not fully cover them.
There are no free gifts!
Best regards,

And thanks €uro for the detailed response. 🙂

Generally, demand reductions (heating operation) through insulation measures have a positive effect. However, the intended heat generator should not be completely overlooked! With heat pumps, for example, ground-source heat pumps, from a purely economic perspective, excessive insulation often isn’t necessary. The situation is somewhat different with conventional heat generators (e.g., gas condensing boilers). Furthermore, the actual demand (capacity, energy) for heating and domestic hot water is crucial!
With heat pumps, sustainability is greater; with gas condensing boilers, it is generally less prioritized. However, the theoretical combustion value efficiency (gas condensing boilers) for domestic hot water is usually only effectively usable under certain hydraulic conditions!
Best regards.
