Default How can I cool my loft?

One could, it makes very little difference however.


That depends on how well the house is designed for natural
ventilation. I know of houses, including my own, where the
appropriate use of windows and vents allows a nice even temperature
to be maintained in hot weather, day and night, including the
southward facing public rooms.


It is not clear to me how this can be achieved in practice with an
"ordinary" house. For example I have a 1960's semi (well-insulated)
with a large new extension on the side. The front faces roughly
South-West.
If I try to open the ground floor windows/door on the back (cooler
side) and the upstairs windows (hotter) to attempt to use convection
to cool the house I get negligable improvement.

Yesterday it will still around 29 in my bedroom at about 10pm.
Outside temperature read 24 on the same thermometer.

Only 7.5% of the UK land mass is settle, with about 2.5% paved. They only
allow you to building in certain areas. This creates an artificial land
shortage which then raises prices for land available for building. The
system is Slatinist based on centralised quota. The free market has little
influence in housing in the UK

Read for land ownership:
Who Own Britain by Kevin Cahill.

Well worth reading the docs I have linked to below.

Fable
(an analogy of the planning act and vehicles. Substitute car for house)

The Car and Lorry Planning Act of 1948

The new Labour Government which came to power in 1945 set about creating a
democratic socialist state in which the economy was properly planned rather
than left to the vagaries of the market. Many industries were nationalised:
coal, rail, gas, electricity, steel and, in 1947, a Town and Country
Planning Act was passed. Since towns were now to be properly planned, and
other means of transport were now publicly owned and properly controlled, it
was argued that the production and distribution of motor vehicles should
also be planned and controlled, and this was achieved with the Car and Lorry
Planning Act of 1948.

The Act set up a system under which the production of cars was planned on
the basis of past ownership patterns and no more than this number were
allowed to be produced. No vehicles were allowed to be imported, and anyone
wishing to order a new car had to wait until a manufacturer had obtained
production permission from the local authority on their behalf. The
application was considered by the local transport planners and by the local
transport planning committee, which could refuse or grant permission. To
make the system democratic, people could write in to say why someone should
not get permission. Often the objection was based on the fact that the
objector did not have a car and did not see why his neighbour should have
one. Such people were called NIDDIES from the acronym NIDHI (Not If I Don t
Have It).

As incomes rose and the population increased the demand for cars increased,
but the number of cars permitted to be produced did not increase to the same
extent. It was felt that allowing more cars would create unfair competition
for bus and rail.

The price of cars rose substantially. It was argued by some that this was
because of the constraint on production, but the transport planners thought
that this was not so. The constraint on production did not affect the price;
the increase in price was solely caused by the increase in demand caused by
things like lower interest rates, so they said. And anyway car prices were
not their concern. They were concerned with the real economy. It was for
them to plan and for the market to follow.

People adjusted to the situation of course. They drove their old cars as
long as possible. Indeed it was rare for a car in Britain to be scrapped if
there was any possibility that it could be repaired. After road accidents
cars were reconstructed which would have been written off as scrap
elsewhere. Tourists visiting Britain were often overwhelmed with nostalgia
when they discovered car models they had not seen for years in their own
countries.

They also adjusted to the increase in the price of cars. People who had cars
discovered that far from depreciating in value the price actually increased
over time. This increased the demand further as people without a car felt
that they had to get a foot on the ownership ladder. Banks were willing to
lend money on the security of the vehicle. Of course, as car prices rose
people who wanted to buy cars found that they could not afford anything very
large and so the cars built and sold in Britain became much smaller than
elsewhere.

The transport planners said that this showed that small cars were what
people wanted in Britain. The British were different from foreigners who
wanted large cars. Indeed, people had so much invested in their cars that
they resisted any relaxation in the control of production because this would
result in their cars losing value.

The justification for this came to be that the limitation of car production
was in the interests of global sustainability, to reduce pollution and fuel
usage. Some economists said that the stock of old cars in Britain polluted
far more and were far less fuel efficient than the newer cars used
elsewhere. But these critics were ignored, because after all, they were
merely economists and what did they know...

Read the three documents below in the order given. These will fill you in.

My house is nothing special. It is a standard design that can be
seen in many parts of this country.
