I spent lots of time working on green roofs, commercial and domestic. From what I'v seen both domestic and managed commercial roofs, unless the sedums are on deep soil (intensive roof) they just get scorched and die. Even the best managed extensive roof will die unless you run sprinklers continualy. You end up with a brown mess and worse albedo than a reflective roof covering. The only sedums that seem able to cling on in these conditions are super fuggly. Not olives! Have you ever eaten a UK grown olive. Yeurgh...

Also make sure not to have doors that automatically lock when they close - lift to lock only. Although these don't always work easily single handed, they are still easier at waist height than yale lock handle combo. A single key for all locks is a boon as well.

Yes, that's what I was thinking! I should have put 'rather specific applications' in air quotes. I was once given a tour of one of those dodgy 'specific applications' (don't ask🤫) and they applied the most rigerous scientiffic approach I've seen outside of a lab! It was all chemical testing, clipboards and graphs... They had also had the most jerryrigged and terrifying electrical system I ever came accross (and I once worked on a house without a fusebox that was wired by Victorians, so that says something). Lengths of rebar rod wrapped in newspaper...

I remember a billion years ago there was a requirement for 5m distance from ground to blade tip (and from any windows) for building mounted units. Not sure about free standing rules. This will only be 3-400 watt max turbine. Noise will be zero unless you stand right under it.

What building regs requirements would apply to a lampost on a public throughfare?

Ah yes—when I finally move from the building works into the garden, the greenhouse will get some special attention. I’m thinking along the lines of compost heating, like the Victorians used for fruit houses—possibly even combining it with an outdoor composting toilet! I’m still not entirely convinced by the whole hydroponics approach. It seems to be most successful in rather specific applications, rather than as a broadly useful growing method. I was actually thinking more about changes on the house side of things. For example, I’ve incorporated more external greenery to create a kind of “cool island” around the house—the fruit and nut production is a nice bonus.

In light of current and future changes to UK environs, what other provisions should be looked at. I already considered these when building my extension and upgrading my house (unfortunately Covid restrictions meant that some of these were unavailable/unaffordable at the time of build) : Larger roof overhangs for better shading and and rain protection Larger gutters for higher rainfall (I went for deepflow, but I now think that was a mistake as we still get over flow, so may change to industrial or import some of the larger metal gutter systems they use as standard in Hungary Breathable and high decrement delay materials for roof insulation - along with an agressive roof ventilation stratagy to ensure that any moisture can wick away in winter / damp periods High Albedo roof coverings. (I wanted to buy white EPDM but this is unavailable in the UK and expensive to import from the EU. Now looking for reflective paint suitable for use with standard black EPDM) High maintenance 'green' roofs are probably not an alternave that is sustainable in the UK climate going forward As much rainwater storage as possible to allow for garden watering (and 'other' activities when the privitised water industry has sucked every last penny into shareholder accounts and bonuses and shuts down) Composting toilet for the same reason. Breathable (sorbative) insulation and high decrement delay wall materials wherever practicable House designed for level access and services suitable for old and infirm residents (raised socket hights, wide doorways, provision for stairlift or through floor lift) Plenty of fruit trees and bushes to provide shading, localised cooling, and dependable food supply External shades or shutters on South and West facing windows (Probably better make that steel shutters on all windows to deal with the innevitable civil unrest when the economy collapses...) No 'smart devices' whatsoever to go wrong/be held hostage to Sorry, that got a bit bleak at the end! I wan't to be a 'Positive Prepper' What else?

It's a street lamp. You can see the lamp above the solar panel (maybe it is self powering at night 🙂)

Not just boilers. When I finished with the solar industry (which by then was was full of cowboys - shocking installs in the literal sense) I moved into stairlifts. It was supposed to be a temporary job but I ended up doing it for 5 years. The most depressing 5 years of my life. Anything to do with the elderly or infirm seems to be a licence to print money by unscrupulous salesmen and uncaring stairlift 'engineers'. If you thing BG is bad, try dealing with Acorn. I could tell you so many stories...

Ah OK, I re read Part G and you are correct, it is 125 litres of 'wholesome water'. But we should never let the facts get in the way of a good discussion... 🙂

Our Building regs assume up to 125l hot water per person per day. Presumably because we will all be washing the sweat off more often... 🙂

Add that to the increased use of woodfibre insulation in French cities (Biogenic insulation is required by new regulations), increasing decrement delay, and there is a chance that they can make city living (and sleeping) bearable during ever increasing heatwaves in the next 50 years. Unfortunately, this won't happen in UK cities any time soon, and we all know that the next UK government will get rid of all the 'woke' crap. Like saving energy and lives...

Heat islanding is real and was an issue we encountered when installing solar (we had maps for heat islands within London and would reduce our predicted generation accordingly. We later made our own more accurate heat island maps based on actual generation figures.) Although each individual energy input is miniscule, collectively it has an exponential effect as Aircon has to work harder and harder to cool the same air. In a city there is no cool air to pull in due to all the Buildings / roads / concrete infrastructure transfering heat to it too Some studies suggest that large deployment of solar pv panels might actualy cool the air slighty, and it seems natural a no-brainer to install PV and Aircon together .

Geocell recycled foamed glass agregate. That way you get insulation and hardcore in one product. 250mm depth = building regs slab insulation. Also does not need a membrane unless you are in a radon area as it does not wick moisture Not so cheap though.
