Planning a gable roof and roof slope

..Why have two full floors prevailed? Could you please give an example or a reason?

Prevailed was probably not the right term. Maybe it would be better to say that it is increasingly being implemented this way. There are various reasons for this, for example:

- less built-up area
- energetically favorable A/V ratio
- better summer heat protection, since especially the roof areas have a rather high share in summer cooling loads.

Whether these are criteria here depends on one's own objectives. These can certainly be, or fortunately, different.

... Especially in winter, you need them the most, don't you?

Not necessarily, because the annual balance counts. Photovoltaics at any cost is of course nonsensical. Therefore, a sales-independent yield simulation should be carried out beforehand. This allows determining to what extent deviations from the ideal situation are still acceptable.

Hello Euro

Photovoltaics at any price is of course nonsense.

I agree with you 100%.

Therefore, a sales-independent yield simulation should be carried out beforehand.

I consider that a nice dream
Do you, as an MEP planner, do such yield simulations?
Otherwise, you will have a hard time finding someone for that...

Because the industry has boomed so extremely in recent years, everyone is currently trying to sell you a photovoltaic system. Even people whose technical understanding is not even enough to turn on their own PC
Already with the keyword *independent* it therefore becomes difficult.

Then there are a bunch of people who call themselves "experts" – unfortunately this term is not protected in Germany...
Very few of them know what they are doing...
But how are you, as a simple homeowner, supposed to check the quality of such a self-proclaimed expert?
You would already need an expert who evaluates the expert

Hello!

Otherwise, I can only warmly recommend a building with 2 full stories. Space utilization, floor area, lighting/ventilation, thermal insulation.....

We chose the pretty version with a hip roof - however, if you want to use the attic, a shed roof might be the better alternative.

A high knee wall looks very unusual from the outside - and it doesn't really bring much either.

Best regards,
Tomtom.

...Do you, as an MEP planner, do such yield simulations?

Yes, because this is part of the respective overall concept. Without determining the actual demand (performance, energy) for heating/DHW/ and possibly ventilation, hardly any realistic and sensible solution finding is possible (basic investigation). Solar thermal systems or photovoltaics are partial components in this. Without this basic investigation, it is hardly possible to economically evaluate the sometimes overall quite high investments.

...Even with the keyword *independent*, it is therefore difficult.

Whoever has not understood that we live in a pure sales society, where the seller cannot (or does not want to) provide independent advice, simply loses out and has to settle for what the trained seller pushes on them.

...Then there are a bunch of people who call themselves "expert witnesses" - unfortunately this term is not protected in Germany..But how do you, as a simple homeowner, check the quality of such a self-proclaimed expert? .

This applies analogously to other fields, e.g. energy consultants. Here it is helpful to inform yourself in advance about education and references. In addition, a good indicator is how the consultant approaches the task. Anyone who immediately pulls out the "non-plus-ultra solution" without sufficient basic investigation probably does not care much about independence and objectivity.

hello everyone, I am new to this forum...and would like to know the following: for our little house in Liguria we need a new roof... and construction wood is precious in Italy. so absolutely minimalist...and preferably portable. the question now is: how strong do the ridge beams need to be? key data: exterior dimensions of the house: 4.30m by 6m, ridge along the long side..., therefore the ridge should consist of two parts so we can take it in the bus, it should meet on a steel beam (it is like that now)... as rafters we would use existing wood (9/9). currently there are no beams, the rafters rest directly on the outer wall, we are considering whether to do it the same way again or to install a beam. the roof pitch should be about 16° if I have read correctly so far from the internet (the roof will be covered with normal roof panels...)... would a ridge beam of 20/20 be oversized, there is no snow load after all? best regards Susa

Hello,

the question now is: how strong do the ridge beams need to be?

Only a structural engineer can help you with that........ no one can tell you here
