Questions about the energy standard

Ask about wall construction, materials, insulation thickness, roof structure, base insulation, windows, etc. Installed heating system, ventilation concept, homeowners' association or not, direction of the garden. Once you know all that, you can better assess whether it is your dream house or not.

Then I misunderstood your post #5 ...

Does the Energy Saving Ordinance 2014 not only apply to building applications from 01.01.2016?

Does the Energy Saving Ordinance 2014 only apply to building applications from 01.01.2016 onwards?

No, it has been in effect since 1.5.2014; only part of the provisions come into force as of 1.1.2016.

No, the Energy Saving Ordinance 2014 already applies to all building applications submitted since 1.5.2014, but essentially it looks like the current rules are comparable to the limits from the Energy Saving Ordinance 2009, and stricter limits will only apply from 1.1.2016. Basically, a work with two different values, depending on the date. In this way, the limits have already been set today for the future without the need to create a new Energy Saving Ordinance 2016, which has led to planning security for the next few years.

But a professional can probably explain that better and present it completely correctly.

Well, that was my point (or rather the one I wanted to make): No one is preventing anyone from building according to the stricter 2016 standards already today.

But that is rather unlikely to be the case here.

I suppose so too.
