What's all this p155 and wind (Waterways) got to do with old buildings ?

If you read what I wrote I said superinsulation and air-tightness is the way and passive solar third. Passive solar does work in the UK and the sun shines on every house.
To Ged, solar hot water is feasible in the UK as well. You can cut the water bills by half. Payback is another matter at the mo' but id it is stabdard the prices comes down.
They do not look at the Deveci link I gave. If they are standard for new homes and improvements then it makes an impact.It will also tell you that this and other carbon reduction measures in the UK housing market are limited by consumer recognition of ?pay-back? ie. these measures cost more than traditional methods
Ventilation can be controlled. Look at the Canadian 2000 standard and the German Passiv Haus. Canadians say "Build tight, ventilate right".Legislation (via the Building Regulations) has improved carbon efficiency at least in the short term but there are longer term deficits which the legislation does not address eg., carbon footrint of manufacture of high-tech, carbon-based, high-value insulants and composite construction boards - such as SIPS (incidentally SIPS requires ventilation which reduces the efficiency of an 'air-tight' construction;
Timber framed flats up to 5 floors high are being built in London. They are so well insulated no one ever uses the heating systems.needs to be (steel-)framed in anything other than extremely simple construction and claiming it needs no heating system is just a tiny-weeny bit exaggerated...). All of which points to lower-tech, lower-cost or re-cycled solutions.
Again, none of this put any cost on house. SIP panels? Lay the base and the house is weatherproof in a few days and the fitting out can be done at any time of the yearAnd, at the end of the day the consumer always pays; no one picks up any tabs and stays in business.
That is incorrect.Denser cities are not necessarily more carbon efficient if new homes in suburbs (the villages) are made of SIPs and prime transport is electric metro using supercapacitor brake regen.Having said that, these measures to reduce the carbon footprint of individual buildings have nothing to do with planning environmentally sustainable cities other than to say in passing that denser cities are inherently more carbon efficient in that dwellings share heating and cooling surfaces (walls, foundations and roofs).
Read above. Carbon footprint of cities is over stated and there is no need to cram us all in like battery hens while leaving the countryside empty so a chosen few remain billionaires at our expense. Massive reductions can be done in industry and pushing freight to electric trains, coastal ships, etc.Clearly, you have nothing else that might dispute the argument that lower density cities create more carbon footprint.
You didn't read what I wrote. The MK conceptual model using a metro not high speed roads as transport mechanism. BTW, as there are few traffic jams, there is little pollution through kerbside emissions, and the over million trees planted around the grid roads negate car emissions. Travelling around the grid you see nothing except mainly trees and bushes, giving the impression nothing is there. The centre buzzes at the weekend and the suburbs (villages) have their small centres where no main roads run through and traffic calming measures exist. The people who live there love it. It is the largest shopping centre in the south east after London. The road system is the best in Europe, if not the world. The population is rising rapidly and the place is larger than Sunderland and Preston which are "cities". It is a massive success.BTW, I have looked at Milton Keynes. It?s a horrible, soulless place with no sense of place or focus and God help you if you want to walk anywhere.
The MK conceptual model using a metro to mesh the suburbs, having a high density city centre and road reduced from large to small to discourage cars, would be great model for Liverpool.

Deprived of its unique dockland waters Liverpool
becomes a Venice without canals, just another city, no
longer of special interest to anyone, least of all the
tourist. Would we visit a modernised Venice of filled in
canals to view its modern museum describing
how it once was?

Well, I reckon that really is so much p1ss and wind...
Your superinsulation isn?t. SIP panels have a ?U-value? of 0.4 W/m2 K in laboratory conditions and without windows. UK Building Regulations require that wall construction gets DOWN to 0.35 W/m2 K ie., SIP panels may be a revelation to the energy-profligate US market but they don't even satisfy the current UK building regulations.
You claim houses made of these materials don?t need heating and so show that you don?t understand the principles of insulating material ie., they hold up heat loss just long enough for the external daytime heating cycle to take over from the night time chill. You have to put heat in in the first place!
Your air tightness doesn?t work with your ?superinsulation? which requires mechanical ventilation (you should read the stuff you swallow wholesale) and the sun don?t shine so much in the UK and even if it shone all day, the day ain?t so long in the winter, in case you hadn?t noticed.
Probably because you wouldn?t be bothered to introduce the material, draw your own original conclusions or get people interested in it. Perhaps you didn?t understand it yourself.
In these very cold conditions it?s probably quite wise to close the door (and hermetically seal every crack and crevice) but it comes at an environmental cost (of mechanical ventilation/heat recovery/loss and poor air quality or both.
Yes and this adds substantially to the cost of an otherwise 'frameless' construction and again no heat in means... for god?s sake, do you imagine the insulation heats the house up? Jeez...
Energy saving measures cost more. Go buy some! Do you seriously think the market is so competitive that builders will cut their margins to put it in when there is almost zero appreciation of the benefit?
A single storey house constructed in SIP panels can be put up very quickly. So? And why would you wait to fit it out? What for???
The point, made quite adequately, is that houses that are joined up share walls and therefore lose less heat. Heat loss occurs across a gradient or difference in temperature. Two houses at an equal temperature lose no heat to each other through a party wall. Similarly a first floor flat is ?insulated? by both a second floor flat above and a ground floor flat below. This is a denser configuration than a single storey house (and loses heat through every surface). Now, think about this carefully before you come back with more cr*p.
SIPs, yes we?ve talked about SIPs and I am sure brake regen is lovely but it can apply wherever
Says who? You? and nobody?s talking about battery hens. We?re talking about putting people into sustainable communities at established densities on vast tracts of EMPTY and derelict land in our inner cities.
Unfortunately, I most certainly did.
What happened to the solar miners lamp your were inventing Ged?
Woooaaaaahhhhh. What a heavy duty thread this turned out to be.
(Swift exit...)
Keeping it real!
