Re: [shs-talk] Re: Nice 200 sq ft tiny house
- Nice thing about small houses on wheels is you can move them around so the windows in winter get the solar heat and light from the south and west sides. Yet come summer turn the house so the side with the most windows are facing north and west so the place stays cooler.~: Beth in the California Sierra Foothills:~

I am not saying that there is anything, in particular, that
they should or should not have done (I could make several
suggestion, but did not). I just thought it would be helpful to
point out the inaccuracies in certain claims that were made.
It could have been design/built to be even more energy
efficient, but such a small home with the good insulation
that it has, will use very little energy anyway, especially
around Santa Fe, which is a really easy Solar heating
climate. Santa Fe houses can be designed quite far
from optimal, and still perform pretty well.

sun, more than a wall window would. But, it would make a nice
vent. A skylight might have a shade over it, during Summer, but
that adds complexity, so a compromise might be an insulated
interior covering, such as Reflectix, that would block sunlight,
but still allow venting. A dark shade might even be rigged in
a way to create a Solar chimney, for when daytime venting

some South facing windows (which most house have) is also
having provisions for controlling excess Solar gain, not just
with fixed overhangs, but with control of excess heating
season overheating, usually via thermal mass of some kind.
Without that, it is simple Solar tempered, which is orienting
the building shape, and standard windows, to optimize a
small amount of Solar gain. A lot of people think that their
houses are "Solar" because they experience apricity (warmth
of the Winter sun) through windows on sunny Winter days,
but if those windows do not have a significant net gain, and
especially if they are net energy losers, that is not Solar heating.
Virtually all houses will overheat at sometime, during the heating
season (when there are Heating Degree Days) Passive Solar
design is about performance that significantly exceeds mere
Solar tempering. Confusing claims distort the public perception
of what real Solar heating is. However, as I said, that does
not mean that it is not a nice tiny house.
> Would still be a good idea for more northern locations.It is possible for a tiny house to be truly passive Solar,
or active Solar, or a hybrid, even to be virtually 100%
Solar heated. In fact, it is not all that difficult. Thermal
mass can be provided by small containers of water,
which can be removed and emptied, for moving.

that is a sign of an oversized heating system. Their little
Dickinson is not that. It is a good choice, if you wish to
have to burn fossil fuel for heat. I also see nothing at all
wrong with their wall insulation. I only pointed out that
their claim of "super-insulation" was misleading. Though
that term has no precise definition, it has a tradition of
being used to mean wall Rvalues in excess of around
R30, and roof insulation that is well in excess of the
standard code minimum of around R38. I doubt that
their roof has even that. Again, the tiny house is nice.
A few of the claims, are just inflated.

claims were all part of the list of features on the page of the
link that was posted to this group. Again, there is more to
"passive Solar" than having a few South facing windows,
there is more to "super-insulation" than 2x4 walls, and there
is more to rainwater catchment, than just a metal roof, with
no gutters, or a cistern. That is all that I wanted to point out.

Fifth wheels are often used for more than just short
vacations, and more are now being designed to function
as full time homes, so they are being done very well.
What I wanted to point out, by that comment, is that
there are a lot of fifth wheel layouts that work the same
basic way, with the bed in the raised section, accessible
through the bathroom, with the kitchen and sitting area
behind. That is very typical for a fifth wheel floor plan.
The reason, is because it works very well.

are often more convenient, and even more stylish, than
having to climb a ladder. They incorporate more main
level living space, within the same wheelbase, by extending
the bed area, over the truck bed, which also helps them to
handle better on the road, and allows them to be heavier..
Of course, many (if not most) fifth wheels now have at
least one bumpout. It seems, for energy and economics
that there might be an advantage to buying a used fifth
wheel, and using an awning room as a Solar sunspace,
