New construction lighting planning and implementation

Did the lighting planner just "throw in" the luminaires like that? I would expect a DIALux calculation from a lighting planner.

Apparently just thrown in. His offer is unfortunately not detailed. It only states the number of dimmable spots and the number of non-dimmable spots. A provider I visited yesterday, who should actually alternatively offer the planning products, also frowned upon that and showed me what a lighting plan looks like from his side. You can see a variety of information for each luminaire on the floor plan - similarly extensive to reading a detailed mind map.

Considering the countless trades and information to be obtained in this regard, I hadn’t had the DIALux calculation on my radar. A pity.

Hmm


Does A27 .. A28 etc. mean that these lights turn on together with one switch? Then I would reconsider that and possibly separate some or split them into 2 different circuits. For example A27, A32 .. also in the hallway.
And think carefully about where the light switches will go, which lights might be switchable from different places with two-way switches (bedroom bedside lamps and ceiling light each from the door and from the bed) etc.

Back then, I prepared the following for the electrician for each room in my apartment. Then we went through the sheets together once:

And every room turned out as drawn.

I expect a lighting planner to use a tool that automatically calculates, regardless of whether it also provides a visual simulation for the client, at what light intensity and after how many meters the next lamp belongs. So that he can specifically plan a seamless illumination. Apparently, there are also rows of lamps here that are switched together. For a nighttime trip to the toilet or the fridge, you don’t need glaring light. Rather just a quarter, formed from every second lamp in a row at half power*. I don’t see that taken into account here. When reading in bed, I gradually sink lower and then sit up straight again at the next chapter. This row of spots would not be my friend in that case. He also wants to read and she wants to sleep, or vice versa, which I don’t see considered here. From my point of view, a poor performance, which the planner will hardly admit. So unfortunately a learning experience and a learning experience

*) Such things are done with a proper home control system: if you operate a light switch, for example, between 11 p.m. and 6 a.m., you don’t have to dim down first; that is then preset automatically. The best way to do this is when the control system can address each lamp individually (also with combined operability via a common switch).

We are considering having at least the upper floor re-planned by someone else. The basement is okay. Nothing more can be done on the ground floor, since the precast ceiling has almost certainly already been ordered to fit the spotlights. But the biggest problems are probably in the upper floor as well. And wall lights could possibly be adjusted on the ground floor too. The tuition fee and lesson learned are bearable. More important now is the question of how we save what can be saved. Especially since another provider, who at first makes a good impression (the other one did too), could turn out to be a failure.

Well, you'll have to live with that now: my planner - I can say that for sure - will no longer take on a project where someone has already botched it. I already gave you the key data: have him show you his planning tool, whether he can simulate which square meter will be how bright when certain lights are hanging where. Don't let him skimp on cables: if you want to automate later, you will be grateful for every lamp that can be controlled individually - at least for having the cable routes prepared for that. Dimmability alone is "latest technology" from 1980.

By the way, you can find the references of the lighting planner if you google IBO Beleuchtung.
