> Nevermind the fact that all over the world people have been living in smaller houses on average compared to those in the U.S. for many years.

Yes, my TH will the size of an average townhouse in sq ft in Ireland.

> what I think is unfortunate in house design and construction is that houses are built for use < 100 years, aren't easily upgradable via conduits, etc.

I agree but if you're clever you can low-tech hack by inserting pipes through the wall which contain what I'm going to call 'guide wires'.

That shall allow one to insert new cables into walls in the future.

You have to appreciate also that buildings get a 'deep upgrade' every 30-50 years. If only because with today's shit tier new growth wood and shoddy craftsmanship a house deteriorates around the time people finish paying a mortgage. What an unholy alliance there exists between bankers and building/material standards...

> Aerogel's Spaceloft that could significantly decrease residential energy needs is barely spoken of.

Don't tell internaut that! Things said by internaut in the last three months include:

> we do not see things like technologies to make heart attacks impossible or cheap aerogel insulation, the kinds of leaps we made in the past that really lifted all boats.

> using a material invented by them called aerogel (thin strips!) to thermally isolate the studs to prevent thermal bridging, it'll cost me just 1300 to raise the R (insulation) value by a min of 10% - 20%

> suppose the manufacture of aerogel could be brought down by 2 orders of magnitude.

The caveat I have to mention is that getting cheap aerogel production is not enough by itself to effect large industrial level change and an order of magnitude drop in energy bills for new builds. We also need an AR system (a special pair of glasses/goggles) that highlighted the places in the dwelling that require foam, special housings around penetrations, beads of chaulk, all in order to prevent the air escaping. Good insulation is close to worthless without the correct methods to prevent air infiltration.

Myron Ferguson does a nice demonstration of what I'm talking about on Youtube.

The passive house people are getting there but that will take forever unless they can be augmented by AR. So that is a good B2B start-up idea.

> We could be building small modern castles that we could hand down, but instead we still build cheap throwaways.

Yeah. The next generations should not have to worry about building their own houses unless they really wanted to.

My problem with modern building systems is that they are biased towards modern architecture styles I dislike. My attitude is the same as most normal people. Passive house cannot succeed without allow traditional building styles to exist.

Since houses are viewed as bank accounts and not as dwellings by most US folk, it is going to be difficult to convince them not to value marketability over efficiency. Especially since the energy cost is small compared to the finance fees and property taxes paid.

Eliminating zoning rules and "voluntary" homeowners associations and eliminating property taxes would help.

Not worried about that.

The costs of heating and cooling a dwelling + the maintenance and upkeep are actually way in excess (1x - 2x) of the original house price adjusted for inflation. You get... dis-economies of scale the more you go up.

Housing markets are cyclical over long periods with nil capital gain.

Put the two together and you see a dismal end as entropy catches up. Not even to mention that this process shall accelerate if economic growth falters.

> Especially since the energy cost is small compared to the finance fees and property taxes paid.

Energy costs at first appear to be a small encroachment, but they really mount up over time in the most astounding way. I don't have a graph to hand but I remember being very impressed by it.

What is called THOWs or Tiny Houses on Wheels do not pay taxes or association fees. They are classified as vehicles and hence do not need to pay property taxes. They are also not very likely to encounter HOAs since complaints drive them away on their wheels to greener pastures. Sometimes they visit RV parks and pay those fees but those aren't very much.

> Eliminating zoning rules and "voluntary" homeowners associations and eliminating property taxes would help.

Of course! And I think such 'revolutions' will happen in time, because 'living like a normal American/European' will just become uneconomical.

So RVs or campers with a cute name.

Categorically yes, like genetically, but phenotypically no. TH are more home-like and more comfortable, even at this early stage in their evolution. RVs can be quite luxurious but in my opinion they are distinctly different to THs.

That can mostly be attributed to the use case:

RV (original intent) usecase was temporary living, moving often, the TH usecase is permanent living, moving rarely.

It's interesting to think about energy vs finance costs. I will run some numbers for my own house.

I recommend this website:

http://www.finehomebuilding.com/2009/09/18/a-complete-guide-...

Fine Home Building is the HN of construction tech, I never fail to find something useful that saved money or gave me an idea or prevented me from doing something stupid. I'm sure I wouldn't have come across the concept of a Rainscreen (despite reading several construction books) but for them and I suspect that alone saved my butt.

Pipes can be conduits. And instead of guide wires, many use fish tape.

Re:Portland’s Small-House Movement Is Catching On by internaut on Monday October 03, 2016 @09:18PM (#12632677)
By pipes as conduits did you mean empty PVC piping or routing within existing pipework somehow?

Thanks for mentioning fish tape since I wouldn't have heard of it before, it looks like the correct terms are 'draw wire' and 'fish tape' and they are used together.
