ᐅ New construction without solar panels and without a heat pump— is it possible?

Hello everyone,
I’m just at the very beginning of planning a house and am slowly starting to learn about the technical aspects, but I have almost no knowledge so far.
At least I already know that there is an Energy Saving Ordinance 2014 that must be followed.
Now my questions:
- Is it possible to build according to the Energy Saving Ordinance without using solar technology and a heat pump?
- Which measures would then likely be absolutely necessary?
I’m asking because I think that solar systems probably wouldn’t make sense for us due to the unfavorable orientation of the building and shading from the neighboring property.
And I’m not keen on a heat pump; we have gas available on our street and I would prefer a heating system based on that.
Basically, about our project: it’s a detached single-family house with approximately 200m2 (2,150 sq ft) of living space over 1.5 to 2 floors plus a full basement. We definitely want to have a fireplace in the living/dining area, but I have no idea if that would be helpful or rather a disadvantage?
Does anyone have literature recommendations? I’d like to study the topic in detail.
Thanks in advance!

That's true, of course.
I've also thought that, from a financial point of view, it’s probably almost better to just build according to the energy saving regulations without meeting the KfW standards.
We wouldn’t be dependent on a KfW loan or funding financially. We don’t have to build as cheaply as possible, but I also don’t want to spend money “unnecessarily” or “senselessly.”
However, I want it to be nice and comfortable. For us, that definitely includes a fireplace. And I would find a ventilation system very practical. Although I am at home almost all day, we rarely open a window (except the patio door in summer and a window tilted open in the bedroom every night). We also suffer a lot from hay fever (I almost the entire year) and the kids will probably get it too :-(. And I imagine that significantly fewer bugs get into the house when I keep the windows closed tightly.

You’re not imagining the pests... less dirt and dust also get inside the house, as well as all the other things floating around... the mechanical ventilation with heat recovery filters everything out...
But you really need to stop leaving the windows tilted open as soon as possible...

However, it all seemed a bit too expensive for us. Now we are building without KfW certification (24 cm (9.5 inches) wall) and will use a gas boiler. Additionally, we are installing two solar collectors on the roof for hot water production. Furthermore, there is a fireplace in our living room. That’s enough. ;o)
Hi,
We are currently building a detached house of about 145 sqm (1,560 sq ft) and have achieved KFW70 standard without using a heat pump or solar panels.
Key factors were the gas heating system with underfloor heating and a ventilation system with heat recovery. Due to cost considerations, we chose the decentralized ventilation system Lunos e2 with heat recovery.
We also placed importance on a monolithic external wall, so the exterior walls were built with Wienerberger Poroton T9 bricks filled with perlite (36.5 cm (14.4 inches)).

I would be interested in more detailed figures regarding the insulation and technical specifications – we are considering a similar direction but with T8 bricks and a comparable house size, we’re not able to meet KfW 70.

Well, I don’t know... everything is available on the online Energy Saving Regulation site, you don’t even need to search long... it took me about 30 seconds...
I have a central ventilation system and I believe that a new building built to Energy Saving Regulation standards should not be built without one... and also not with a decentralized system but only with a central unit if you have the option...
No one can keep up with the ventilation intervals if they are not home all the time... also, a lot of energy is lost through window ventilation... and you get fresh, filtered air in the house, which should help those with allergies... however, the air will become very dry in winter, so you have to consider whether to use an enthalpy exchanger or humidify the air in some other way.Why do you need to ventilate when you are not home?
Moisture is only generated when people are at home through breathing, showering, cooking...
More energy is lost operating a ventilation system than through simple window ventilation.
A ventilation system remains purely a comfort feature; even energy recovery cannot fully offset the energy consumption of the system.
