Energy demand certificate, who has a clue? – Sailing Forum

It is now also clear to me that the energy certificate, if it can be issued in this way, is of little value.

The energy certificate is worth little to nothing in 95% of cases. The calculated values cannot be achieved if isolation is recommended. There is no armortization of external insulation. http://www.konrad-fischer-info.de is very revealing.

Exterior insulation pays for Home Maintenance itself in the first summer and winter thanks to an extremely better living experience: less hot in summer, evenly warm in winter with less effort. The further amortization occurs when renting or selling is to be made: houses without are traded in the good segment in the area of my activity only far worse on the market.

Despite environmental concerns regarding production and/or disposal later: Never without, if possible.

But I have completely different experiences from the professional environment. But everyone can throw out their money as they please. I sail……

Then your house was before that, sorry, real crap! And, a beautiful house usually sells itself through emotions. The rest is pole! As with the sailboats.

Mal’n bushes differentiate: A roof insulation helps for the living climate quite quickly, in summer as well as in winter. Anyway, if you only had pans before and nothing underneath. We will soon know what it has achieved economically. We had it done in the course of a complete new covering with wood fibreboards, which was already being considered. The additional costs were not particularly high. Approx. 10k€ incl. 2 dormers for a detached house with 160sqm roof area. Whether it will really “pay for itself”, we will then see. This is quite possible with a service life of 50+ years, especially at the current (non) interest rates.

The exterior wall insulation must certainly be considered in a more differentiated way. In my opinion, this makes sense (only) if you have to completely rebuild the house, have to replaster etc.. And you don’t have to use Styrosomething.

And, yes: houses are certainly sold through emotions, but prices are pushed down by lack of insulation…

In the urban jungle and surrounding area (I’m talking about Krefeld, Düsseldorf, MG, Cologne and the surrounding area) there are few houses with real emotions and very few can afford them. You are happy to find something affordable at all. And this is where thermal insulation accounts for a significant jump in prices. This stands out from 08/15. And that’s paid. Style houses that are intact and have a layout that corresponds to modern living are no longer really affordable for middle to lower upper incomes. Emotions are therefore only created details (great bathroom, balcony, super fitted kitchen or similar). But the mass of people buy sensibly because they invest almost or practically all of their wealth.Attic spaces are always asked for insulation. Without insulation there is a price deduction from normal price, which already assumes this.

Emotions also go “in small”.

No, I mean that normal houses usually already have an insulated roof. Many also have a reasonably wall insulation. I’m talking about booths between 1970 and today. Years of construction before that should already have a renovation behind it. There are, of course, still some zero-insulated houses – no majority until 1945. The entire buildings of the settlement societies are now renovated to low energy – that is the lion’s share of simple living space. Reference: Baden-Württemberg!

From a year of construction 1985 with 125 m2 (usual size DHH) to a current insulation are >= 75,000, – (roof, windows, walls, heating) but relatively little improvement in climate and consumption costs. For example, I do not perceive low energy as a desirable climate. I have more negative than positive examples. The children feel the amortization!

Don’t get me wrong, I think it’s good, important and right to optimize houses energetically. But you also have to be able to afford it. A house that has zero insulation… How many of them are left? 15% ? I read the number somewhere a long time ago.

And, what did all the measures help? We produce more dirt than ever, far away from the limits we have set ourselves. If an insulated façade burns down, 25,000 x more dirt is produced than it would save over a lifetime. This was written in the Sun after the devastating insulation fires in the UK. By the way, nothing happened to us after checking the facades and their materials classified as dangerous. It was to be expected, no one has died yet.

Yes, ok. An improvement of an existing insulation only makes sense if you have to work on the component anyway. New roof or extension with new outer shell etc.

That is not the reality of life here. Years of construction before 1970 are by no means renovated, let alone the majority. Exterior wall insulation in old buildings before 1980 I would estimate well below 1/4 of the stock. Single-family homes included. I wouldn’t include windows and heating either, these are completely different approaches.

In the past, an old real estate wisdom said: Over the lifetime of a house, you pay twice the construction costs again for maintenance. There’s a lot of truth to that.

With my contribution above, I just wanted to draw attention to the fact that amortization cannot be measured solely in money in the form of heating cost savings. However, if you have already modernized well 10 or 20 years ago, you can recoup the money over the course of 20-30 years due to rising energy prices, depending on the size and age before renovation. I save about 2,000 € annually due to essentially exterior wall insulation over the last 5 years. This is ridiculous over the years. Regardless of the value formation for the property.

So I’ll throw my hat into the ring. If I would have my hut packed in such a shroud, I assume not to do it myself, 10 k€ would quickly be gone. What savings potential could be generated? Ceiling and windows are insulated. With a good 1000 € gas per year, including hot water, this is certainly not more than 150 – 200 € per year. Then the foam stuff will last forever and in 20 years I will have a ton of hazardous waste.Well, you could also have a ventilated clinker façade built, but there are completely different prices called. I enjoy my fireplace, the wood falls anyway, and you don’t have to run after every sow that is driven through the village.
