Hello everyone!
As some users have requested before, I’m now starting a new thread with the current planning of our detached house, which is about to be finalized.
These are the preliminary drawings for the building permit / planning permission application, and I have one last chance to review them and point out any issues.
It still seems to me that there is less than 1.20m (4 feet) of space between the two wardrobes in the dressing room. Or am I seeing this wrong? Apparently, the rooms on the left and right were overlooked and not adjusted accordingly.
Two Velux ceiling spotlights are still planned to illuminate the upper floor hallway.
In the basement, on the right side in the upper room, a window similar to the one on the left basement side is an option.
We still haven’t decided on the T30 fire-rated door to the garage, even though it is shown in the plans. Most likely, for safety reasons and the limited use of the kitchen at the other end of the house, we will eventually forgo it.
User 11ant pointed out that the right window in child’s room 2 is suboptimally positioned. However, this could still be changed after submitting the building permit / planning permission application. Our architect thinks moving the window to the left would negatively affect the house’s exterior appearance. We’ll have to see about that.

Yes, mechanical ventilation with heat recovery is planned.
Gas would be €5,214 cheaper. That includes the solar collector system. I would need to ask what the cost is without solar if you go with the biogas option.If you have mechanical ventilation with heat recovery, which I assume you do, the renewable energy share is essentially covered! Just go with gas and mechanical ventilation with heat recovery, and that should be fine.

Mainly, I need to check where it is defined that this complies with the energy saving regulations (energy saving ordinance / building regulations).

The specialist company says that flat plate collectors are an alternative. Apparently, geothermal energy is sufficient for these. Geometry has little to do with it; you need surface area but you simultaneously lose the use of that area.R.Hotzenplotz schrieb:
At the moment, there are many reasons to favor a gas heating system. Allegedly, it is possible to waive the actually mandatory solar component according to the 2016 Energy Saving Ordinance if you purchase a certain percentage of biogas. I wonder whether signing the contract was wise when I read statements like these. You don’t need biogas; your house primarily needs _more_ insulation and probably a mechanical ventilation system with heat recovery. An air-to-water heat pump combined with photovoltaic panels could be an alternative, provided your energy consultant runs the calculations.R

May I ask what your concerns are regarding air-to-water heat pumps? By air-to-water heat pump, I assume you mean an air-to-water heat pump. We were offered a pure air heat pump. In my opinion, such a large unit mounted on the exterior wall doesn't look good. I also expect electricity prices to increase more sharply than gas prices. Gas technology seems much more mature and less prone to problems. We currently have a Nibe F 750 and are far from satisfied with it. It doesn’t operate efficiently and requires two service visits from technicians every year... good thing we are only tenants here. We really despise that thing.

An air-to-water heat pump plus photovoltaic system could be an alternative, but your energy expert should run the calculations.More insulation can also serve as a substitution measure for the renewable energy requirement.
An air-to-water heat pump would solve all problems, even without photovoltaics. But this option is not desired.

First of all, check where it is defined that this complies with the Energy Saving Ordinance.This is not stated in the Energy Saving Ordinance, but in the Renewable Energy Heat Act. Out of boredom, I looked it up for you:
§ 3 Obligation to Use Renewable Energies
(1) Owners of buildings according to § 4, which are newly constructed, must cover the heat and cold energy demand through partial use of renewable energies in accordance with §§ 5 and 6. Sentence 1 also applies to public authorities if they newly construct public buildings according to § 4 abroad.
(2) Public authorities must cover the heat and cold energy demand of already existing public buildings according to § 4, which they own and which are undergoing major renovations, through partial use of renewable energies in accordance with §§ 5a and 6 paragraph 2. Sentence 1 also applies to public authorities if they undertake major renovations to public buildings according to § 4 abroad.
(3) Public authorities must ensure that already existing public buildings according to § 4, which they possess but do not own, serve as exemplary models in accordance with the requirements of paragraph 2 when undergoing major renovations. When renting or leasing buildings, this is ensured if
1. primarily buildings are rented or leased that already meet the requirements of paragraph 2,
2. secondarily buildings are rented or leased whose owners commit to fulfilling the requirements of paragraph 2 in case of a major renovation.
Sentence 2 does not apply if buildings are rented or leased by public authorities only temporarily.
(4) The federal states may
1. establish their own regulations for already existing public buildings, excluding federal public buildings, to fulfill the exemplary function according to § 1a and, for this purpose, deviate from the provisions of this act, and
2. impose an obligation to use renewable energies for already existing buildings that are not public buildings. § 5 Share of Renewable Energies in New Buildings
(1) When using solar radiation energy in accordance with item I of the annex to this act, the obligation under § 3 paragraph 1 is fulfilled if at least 15 percent of the heat and cold energy demand is covered from this source.
(2) When using gaseous biomass in accordance with item II.1 of the annex to this act, the obligation under § 3 paragraph 1 is fulfilled if at least 30 percent of the heat and cold energy demand is covered from this source.
(3) When using
1. liquid biomass in accordance with item II.2 of the annex to this act, and
2. solid biomass in accordance with item II.3 of the annex to this act,
the obligation under § 3 paragraph 1 is fulfilled if at least 50 percent of the heat and cold energy demand is covered from these sources.
(4) When using geothermal energy and environmental heat in accordance with item III of the annex to this act, the obligation under § 3 paragraph 1 is fulfilled if at least 50 percent of the heat and cold energy demand is covered from systems using these energies.
(5) When using cooling from renewable energies in accordance with item IV of the annex to this act, the obligation under § 3 paragraph 1 is fulfilled if the heat and cold energy demand is covered at least to the extent specified in sentence 2. The applicable share is the share that applies under paragraphs 1 to 4 for the renewable energy from which the cooling is generated. If cooling is generated by a thermal cooling system through direct heat input, the share that applies in the case of pure heat generation (without cooling) from the same energy source applies. If cooling is provided directly by using geothermal energy or environmental heat, the share of 50 percent of heat and cold energy demand that also applies for heat generation from these energy sources applies. This sounds bad at first, but §7 allows substitution measures...
§ 7 Substitution Measures
(1) The obligation under § 3 paragraphs 1 or 2 is considered fulfilled if the obligated parties
1. cover at least 50 percent of the heat and cold energy demand
a) from systems using waste heat according to item V of the annex to this act or
b) from combined heat and power plants (CHP plants) according to item VI of the annex to this act; § 5 paragraph 5 sentence 3, § 6 paragraph 1 sentence 1, and § 6 paragraph 2 apply accordingly,
2. implement energy-saving measures according to item VII of the annex to this act, or
3. purchase district heating or district cooling according to item VIII of the annex to this act and cover at least the share according to sentences 2 and 3 of the overall heat and cold energy demand from this source. The applicable share is the share according to § 5, § 5a, or according to item 1 for the energy from which the district heating or district cooling partly or entirely derives. When calculating according to sentence 1, only the purchased amount of district heating or cooling that is calculated to come from renewable energies, waste heat utilization systems, or CHP plants is credited.
(2) The obligation under § 3 paragraph 2 is also considered fulfilled if solar thermal systems according to item I of the annex to this act are operated on the roof of a public building by the owner or a third party, provided the heat or cooling generated by these systems is made available to third parties to cover the heat and cold energy demand of buildings and is not used by these third parties to fulfill an obligation under § 3 paragraphs 1 to 4. Finally, item V of the annex:
V.
Waste Heat
1. If waste heat is used by heat pumps, items III.1 and III.2 apply accordingly.
2. If waste heat is used by ventilation systems with heat recovery, this use is only considered a substitution measure under § 7 paragraph 1 item 1 letter a if
a) the heat recovery efficiency of the system is at least 70 percent, and
b) the coefficient of performance, determined as the ratio of heat recovered and used from the heat recovery to the electrical energy consumption for the operation of the ventilation system, is at least 10.
3. If cooling is used that is technically utilized by systems directly supplied with waste heat, item IV.1 applies accordingly, except sentence 1 letter a.
4. If waste heat is used by other systems, this use is only considered a substitution measure under § 7 paragraph 1 item 1 letter a if it conforms to the state of the art.
5. Proof according to § 10 paragraph 3 is
a) for item 1, certification by an expert and the environmental labels “Euroflower”, “Blue Angel”, the “European Quality Label for Heat Pumps” or an equivalent proof,
b) for item 2, certification by an expert or certification by the system manufacturer or the specialist company that installed the system,
c) for items 3 and 4, certification by an expert. Many roads lead to Rome. General contractors usually know only “their” way. Good energy consultants know several others.
