Usually on joist I think. Everything built in the UK gets wet, most houses stay up.

I think you mean kW, the power the ASHP is drawing, not kWh, which is the energy it has used. If you are getting frosting at 6°C, some sound wrong especially if you are not getting enough time to heat the slab up a bit.

People may want to pay for a design, then get others to do the work. This may mean that things get changed. Claiming it is a 'legal thing' is a pretty poor reason to not give a customer what they are paying for, not as if a house is a service (to crib a software term).

It is how TVR did their development.

What do you consider a smaller house? We have an architect on here who showed off his 'small house' conversion. The place was nearly 3 times the size of my house. Same architect used to teach, as part of his course, he got his students to read the dictionary and find odd words to use to describe their creations.

Not sure if anyone has mentioned it, but there is the IP side of things. Some people get a bit narked when they ask an architect to design a house, then all they get is a small PDF, with no dimensions. If people pay you to design them a house, they want full drawings/access to CAD files without any restrictions. That is what they are paying for. My very first post, over at the 'other place', was about open source house design. In a former life, I worked as an automotive engineer, house design is a piece of piss engineering wise. Not as if a house has to corner at 150 MPH, have 2 tonnes smack into the side at 30 MPH, have the safety feature do nothing for nearly all the time, but must work once when needed. My old banger of a car has electric windows that work faultlessly, doors that open with a remote control and disables the alarm/immobiliser, and on a good run, can do 70 MPG. Houses are not much better than caves when it comes to design.

Did the windows turn up on time and fit. Personally, I would keep quiet about that as most of the projects are disasters. And avoid the words eco and sustainable.

No, shed light.

Can you set your ASHP up to do the DHW between 11AM and 2 PM? (or whenever your PV is most likely to generate the most, on average). And have a diverter to directly resistance heat the DHW in the summer. Only if the diversity allows it.

Get a half decent battery powered one.

That is about 2/3rd of my total lighting load.

Plus yourself that may be adding 100W.

It is even worse in one man bands.

They need to get there act together then. https://supplychaindigital.com/sustainability/analysis-how-buoyant-tesla-defying-global-chip-shortage

Boat ones tend to be low power devices (200 to 600 W), put them on land and they will produce even less. Power generation is proportional to the cube of the windspeed.

That is why there are incentives to install them. It is an immature market in the UK at the moment, but that will change. I remember the same argument used during the PV bubble, now you can pick up kit cheaper than windows.

There is an upper limit that silicon panels can deliver, around 37% I seem to remember. The 20% figure will be a standard test, they can deliver more, but not by much.

Much depends on how little you are prepared to not spend with the 'professionals'. Some on here have spent 100k by getting architects, environmentalist, bat and bird watchers, newts moved, walls and fences, keeping neighbours happy, plumbers and plumbing systems that need certificates. If you really want to build cheap, go to college and get some relevant certificates i.e. Limited Scope Part P, H&S certificate. Or just find a house that is suitable to renovate.

These kind of planet killing (expletive deleted)ers should be charged £5/kWh, and £100/day meter rental. Do they have a BEV 'because they are green'?

Many years ago when I first started lecturing, and was in the process of moving house, I forgot to get my laundry sorted. So went to work with no knickers on. Was delivering my lecturer and then thought, 'i got no pants on, wonder if the students know'. Was a good delivery.

Smart homes are great, until you misplace your phone. What happens when the provider stops updating the service, or removes the service. Have our lives become so busy that we cannot switch a light on at night, or we have become so weak and pampered that the house must be at the right temperature just in case 'we get a chill'. Don't was time, effort or money. Just get your house as airtight and as well insulated as you can. It will be cheaper.

How many sweaty people are currently working in this building?

I understand the concept of this, but usually in a new build, the indoor climate is not the final climate i.e. colder and damper. I would think it is down to the adhesive. Do you know the chemistry of the adhesive type i.e. PVA, PU, acrylic, epoxy?

When it comes to industrial scale generation, PV is a better use of land. Large turbines have been generating pretty close to their maximum limit for about 20 years now, PV (silicon) is only now getting close and has a few more percent to go still. Depends on demand and usage patterns. There is not one size that fits all.

Best thing to do is drive around and see what exterior finishes people have used. If you like them, then find out what they used. Cornwall is a long county, or country, and it will depend what your micro climate is like as to how finishes weather. My house gets battered by the south westerlies, then baked in the few sunny days we get. Even the concrete render is showing its age.
