I will do just this. Was looking for a direct link maybe to the question as some people have discussed this in depth and may already know or have a link. There is a vast amount of content on here. Which is great. Not enough hours in my day clearly…

 

It is sometimes more effective doing a Google search with +buildhub or site:buildhub.org.uk in the search box.

Rishard, I am not trying to be difficult here, but you have to remember this is a pro-bono community.  The regular posters who answer most questions tend to get pretty fed up answering some subtle variant of the same Q for the 20th time.  I always search a forum for the answer to a Q before asking.  90% of the time good Q and A resolves my issue, and when I do ask it is on some specific point that is more likely to get an answer.

 

Apologies. I will delve into the archive. 

No apologies asked for or needed.  I am just trying to say that there is a lot of gold and gems there – in terms of useful knowledge and experience – amongst threads and blog posts.  Well worth mining! 😊

Not your 'job' anymore I know, but it has been suggested, quite often, about easy links to the usual stuff i.e working out U-Values from multiple layer make ups. I suggested a simple HTML5 calculator, but got shot down as it 'is too difficult', but not by you.

I am with @Ferdinand  use Google to search the site.

@SteamyTea,  One of the strengths of the StackOverflow sites is that if I am learning about a new topic, then I will do a search by descending votes on the associated tag and then scan through the questions and drill down on any that look interesting.  The nearest that we have is the "Sort by" selector which allows you to sort topic by #comments and #views descending which does tend to hoist the most valuable topics to the first page or two. 

 

On another forum that I used to be a moderator on, the mods introduced a "Moderators Picks" pinned topic  which was a list of interesting / best topics for that sub-forum.  The trouble with doing this is that it is high maintenance and gets misleading if not  regularly maintained.

 

Note sure that we can square this circle.

Reputation points are one way. But then, for a laugh, I got @pocster to keep voting for me, then I returned the favour, once.

 

This is why it has been suggested that with things that require calculation i.e. thermal losses, electrical power, seasonal heating loads, some basic calculators are created. Nothing fancy, just basics, with an explanation of the workings. 

Then, when we get asked for the umpteenth time about how much insulation to put under an UFH system, we just point the person to the calculator, maybe a permanent link to a page, somewhere near the top, like the banner.

When I suggested this, I was told, not by you, but another, that if it was so simple, why don't I do it. So I did and posted up a link to a simple example.

Then I went to Canada and forgot all about it.

Think I may still have a folder if HTML5 calculators in my PC.

The sort of  Σ( area × U-value ×  ΔT) calc that I did in the blog entry below for Jan daily ΔT average and maybe by month should be within 10% and the following one.  It is certainly enough to explore marginal infrastructure costs and heating run-rate costs.  This is of course assuming that as-build performs broadly as-designed, that you haven't introduced any bridging or insulation flaws.  

 

PHPP introduces 2-D adjustments such as Psi-values, but TBH, if these are at all material then you've done something wrong in your wall / ceiling / slab mate-up.
