Interesting. A Willmott Dixon report shows 520 - 780 kg/kWp. An eTude report, 615kg/kWp. This report, with Craig Jones (he is Dr Circular Economy) as one of the authors shows between 249 - 2104 kg/kWp. So something seems amiss, maybe an editing mistake. Are they using Cradle to Grave or Cradle to Gate figures?

It is both really. I don't think, that in the UK, we need to build in cooling. There may be the odd week when internal temperatures rise to an uncomfortable level for some people, but potable A/C units, properly vented to outside, can deal with that. Thinking aloud a bit, when the sun hits my outside walls, the surface temperature can easily go over 40°C. Not talking @joe90's old south facing conservatory (which I have sat in), I doubt the air temperature went above that often, it at all. So the extra thermal forcing is probably not so dissimilar to not having a sun lounge (the difference being is probably more perceived due to local windspeed).

Try delta.

Or just design out the need to use extra energy.

Dr. Mrs. Mosley may think differently. How many times have I said that adding mass to houses make them colder.

What about hot nights, when PV generation is zero. Generally speaking, the UK climate is getting warmer because we have less incidents of cold, rather than more incidents of hot. The solution is simple, stop installing large windows.

Why would it be different. Power is just energy per unit time, so moving 10lt in 10s is the same as moving 100lt in 100s, or a litre per second. It will get a bit wobbly at the extremes as the pump impeller will allow some bypassing as pressure varies (equivalent bemf).

I may suggest that to my dim neighbour: we have no gas.

So you get a lot of solar gain in the morning and evening. Couple that to higher outside temperatures and you will get elevated internal temperatures. This time of year, a south facing window is usually reflecting more light than enters and is often shaded by the roof overhang. But rather than everyone guessing, how about some data. How hot is the room? What is the window area to floor area ratio?

I was in Totnes yesterday, so popped into the Library where they have a room set aside to the Transition Town movement. They are going to save humanity by encouraging people to use cash and not buy anything new. This is exactly what happened to the Penzance TT group, but at least they did it 15 years ago and disbanded.

Welcome. Which part of Kernow, it is quite long. (Just cottoned onto your username, may place your house) Surf is better in Costa Rica. You will be talked out of GSHPs pretty quickly, but Kensa are your people to talk to down here.

Or those twisted nails. They are very hard to pull out. Nails work by deforming the timber, which then contracts around the nail shaft. Screws cut a channel and rely on the cross sectional surface area to stop being pulled out. Nails, generally, have better shear strength than screws (bolts work differently, they clamp the materials).

Nails, screws and bolts all work in a different manner, with screws and bolts being quite different (has (expletive deleted) all to do with the type of tool used to tighten them). What does the panel manufacturer have to say?

Crystic D8151. It is a flexible polyester resin. Can be used on its own or mixed in with other resins. Also, rather than chopped strand mat, a unidirectional weave can be used.

I must remember to look up the data.

It is better to manufacture with newer and more efficient systems than use outdated technology. What delusions? The education systems has many faults, but socialism and fascism is not part of them. I suspect you think you rote learning is all that is needed. Learn your times tables, names kings and queens of England, find London on a map and if you are female, cook and darn.

That is quite a bold statement. China does have high emissions, but they are the wields largest manufacturing nation, so we really need to account for the embodied CO2e on their exports. As they did not start industrialising until the 1970s, their accumulative CO2e is still way lower than the UKs. This is important because the gasses stay in the atmosphere for decades, and in the case if carbon dioxide, centuries. China is also the largest installer of renewable technologies. So rather that blame everyone else, take some personal responsibility and change your habits.

That is part of the problem though. In a few minutes all you can say is the old tropes, and too many people don't want to believe them (many on here included). As you well know, when educating, you have to break down the existing mental models that people have entrenched in their minds, then start rebuilding a more appropriate model.

Having studied climate change at the academic level for nearly twenty years, and had a serious interest in it for well over 40 years (well more reducing energy usage than climate change), I have got over the depressing, hopeless feeling now. I just try and think up ways to cope (mitigations) with climate change. One thing that I do find frustrating is the lack of understanding of the problem with the general population. The media must start taking some lead hear and stop doing the scare stories. The 'science' is not hard to understand at all, I can teach why elevated levels of atmospheric CO2e is causing higher global temperatures, in an hour. But without 'official' backup from the media, there is little point as you just end up having to counter claim bad journalism.

Uses shielded twisted pair I seem to remember. Though I think a lot of people use converters then CATx.

What level is the ground outside? If higher that the concrete floor then it won't be helping. I am not sure when DPCs started to be used on a regular basis, but the 3 Victorian places I have had never had any.

Same conclusion that Al Gore said in An Inconvenient Truth in 2006. I am sure he did.

There is a comment or two about that in the video

How modified Teslas are decarbonising the UK's homes By David Stock and Madeleine Cuff Strange-looking cars have been cruising the streets of London, Liverpool, Cardiff, Glasgow, Manchester, Leeds and South Yorkshire in the UK, hunting for leaky buildings. The Built Environment Scanning System (BESS) is a modified Tesla, fitted out with extra scanners, cameras and robotics equipment so it collects data on the dimensions, heat loss, materials, age and state of dilapidation of every building it drives past. With funding from Innovate UK, the Welsh government and the UK Space Agency, UK non-profit xRI has built two of these BESS cars. Over the course of three months in 2024, the vehicles have scanned more than 1.5 million homes. The aim is to combine the data gathered by the BESS cars with other information, including drone and satellite imagery, to build a comprehensive database on the state of the UK’s buildings. Collating this information into an AI-powered database will help councils, housing associations and other property owners more quickly design and finance big retrofit projects, the team hopes. New Scientist took an exclusive ride in a BESS car to find out more about this technology and how it can help the UK speed up the decarbonisation of its building stock.
