Poisson Distribution is what chip shops and Grimsby are for. I fear I may have missed the point...

To wrap up, the electric meter is telling me that I have imported 83 kWh and exported 283kWh in the same 3.5 weeks. I am switching to Octopus Outgoing Agile tariff, as I will make some more export payments.

Just having looked at my Octopus, it says I am using between 2 and 5 kWh of leccy per day. Family of one. 200 sqm house. 10kWp solar, which faces 80% E 20% W and is filthy. Away for night of 6/7 Aug, and less sun the last few days. 1 shower per day, usually gas. The Smart Meter app has not detected the gas yet, but I read the meter just for you and it says I have used 1.714 m3 in 3 weeks, which is around 0.7 kWh per day. It was installed and zeroed on July 25th (says the label).

You need one of Blart Versenwald III's off-switches for children. With apologies to the ghost of Douglas Adams. He was supposed to design a race of fanatical superwarriors, and got bored.

This thread is quite an interesting conversation. I'd like to explore what we think "Eco house" means, in the context of the riverside house posted up by @CharlieKLP. There's a separate issue about woodburning being sustainable, which I'll do on a separate post if I pursue it. Basics first. The house posted up is called Backwater, and is fronting a 'lagoon' at Wroxham. Address: Backwater, Beech Road, NORWICH, NR12 8TP. Linky. I'm happy putting that there as it is off their own holiday rental website. The Planning App is here, but the buggers at the local council have taken the docs off the web, and it would take an FOI to get them. (Update: double bugger, the session expires.) This is the site before the development, from the records on Rightmove. It is the one with the boat. They bungalow-gobbled the site for £342k in 2012, which seems a fandabidozi buy. It is 142.1 sqm floor area. The EPC is here, and it is recorded as GFCH so I just don't believe the new one is off grid for gas or electric without direct evidence, based on likelihood (open to correction). It's architect calls it "in a largely off grid area". I hope to God it is the EPC for the old one, as it is an F - and I can find no published info for the new one (was an EPC required to be lodged in ~2015?). And this is afterwards. I'd punt on it now being about ~250 sqm due to partial 2 storey and the rather fatter footprint (which looks like a normal 'you can increase it by X%' rule). Eco-House? 1 - I think Eco House is the most wiffly-waffly term of all of them, which is why it gets used in windy virtue signalling. ISTM that it must mean something different from what it meant a decade ago, and now I think an Eco House should at least be carbon positive and able to demonstrate that in N years it will have recaptured all the emissions used in building it, and be significantly energy efficient to run in ongoing terms (if you like call that an EPC of >100). 2 - This house is 7-8 years old, so I would not expect it to meet that. In addition it has a honking great woodstove and apparently no self-owned local wood supply. I have no data on the heating / cooling systems, and the EPC value. 3 - The absence of solar PV suggests to me that it is not *that* sustainable in my terms above. 4 - Yes, it is beautiful, but imo that has nothing to do with whether it should be called an Eco House. And I think I would love to stay there, but at a couple of K a week I would take the full 8 people. 5 - I think two aspects of Eco House we have not addressed are: a) What about space usage - can a house that uses say double the average UK floor space per person be called Eco or Efficient? b) I question whether a second house for a family can *ever* be Eco or Sustainable on the basis that no one ever *really* needs more than one? Surely Eco is also a lifestyle rule of modesty and simplicity? What do you guys think? Ferdinand

And that if you look if it still exists, you can get a trial version of the SAP software and do your own EPC calculation.

You missed out the Buildhub Scrapheap Challenge Expert Jeremy Heat Loss Modelling spreadsheet. One line summary: very straightforward and seems to get the results roughly in the right ballpark.

One other option for the slope is traditional (coloured?) concrete with metal transverse ribs.

That's interesting, and perhaps where a designer needs to listen to the client - who is the judge and the jury ultimately, whilst the designer is more like the Clerk of the Court advising from a knowledge- and experience-base. Perhaps the client doesn't find a visible drawn curtain offensive, and would rather spend the remedial 5 or 10k on something else, such as a boathouse, Sage-glass, or a row of mature trees.

-3.5k and he will accept the Walk on Glazing.

Octopus Outgoing applied for, and I found the email from my installer confirming that the DNO had confirmed the install. Watch this space.

If you demagnetise Gandalf, you will not be forgiven.

Does CAT6 imply that you have successfully dealt with 45 lives?

Oh fook - get your Knauf products quickly... is it possible to have a powder explosion in a plaster factory? Here's hoping.

Where are you? "Code" suggests North America, perhaps. We can better comment if we know.

Thanks.

Russ Is this automated, or manual? And if automated, which system? (Asking for an acquaintance I sent a couple of your paras to.) I get the feeling it is manual from you account. F

Depends what you have been drinking 😁 (Soda Water, since you didn't ask. I'm an Orangina man. ) Try getting that past the Advertising Self-Appointed Authority.

Are we allowed to be semi-satirical? (Or am I in trouble again?)

> I went for a Bosch which consumes 115kwh/a and isn’t as expensive as Liebherr: I'm just a heavily biased happy customer !

I paid £1400 for my fridge freezer double (list price £2400). The closest thing from Siemens etc was at the time £600 and £600 ish. At that price it was a nobrainer even for a 2 year old one. Given how good it has been, £1800-1900 would have been OK. So ... use your skill and judgement and mark your X. (Just seen your post - I'd argue from the potential in energy prices.) F

So from next year that will save about £82 a year in electricity ! (At £2 per kWh)

More in reportage terms ... - Longer life should be a benefit, if the reputation is warranted. Mine and the freezer are only 8 years old and fine, and had their first 2 years as showroom demonstrators. - Spare parts have been available, and service good. They sent me a couple of bits for free. - Seem to have a greater range of controls than other fridges I have had. - Both my fridge and freezer have "boost" options which are quite vigorous. If I forget the freezer is on SuperFrost, it ends up at -30C. - On the fridge, I would say check carefully for any of the double-plus-good crisper draws which claim to improve the fridge life of veg. You may want it. It is alleged by some that veg are dropping in quality post-Brexit. I got buried under a dogpile of self-identified remainiacs when I suggested a better fridge (a Liebherr) to a certain writer for the G.

>Tell me about Liebherr fridges Mmmmmmmmmmmmmmmm ......

Tx. I may try and see what happens. I have a 2015 email from my PV installer saying they will be informing DNO. But installer is now in scaffolding.
