The courses we've been running over the last few weeks have really brought our site to life, lots of people, camping, fires, we provide all food and we've had evening trips out to see other strawbale buildings in the area. We're not finished yet, Barbara is back for another course 15-19th July on internal clay plastering. This promises to be a master class in working with this fantastic, versatile natural material and if other courses are anything to go by, a lot of fun too. Here are a few words from Barbara recorded last week:

Final course of the year, we're hosting a 2nd lime rendering course 14-20th Aug if anyone wants to learn about lime?

Photos from the previous course:

Never seen lime hosed on before! Smile

Amazing stuff. Any ideas about snow covering panels, or keeping them clean from algae or dust long term?

Good sized array there. Must be 8kW if the panels are 350Watts each.

I was wondering what was going on with the housebuild.

Impressed Smile

Under the PV modules, is that standing seam metal roofing ? The type that is delivered to the site as a coil of flat strip ?
If so, not very common here in the UK, more of a USA idea.

A friend near me had this fitted about 15 years ago, it has proved entirely watertight but went a "nasty colour" turned from dark green to light green.

We don't really get snow in south west Wales... maybe once a decade there's a few inches for a few days. They are fairly accessible for an annual clean.

They are 270W panels for a total of 6.5kW.

Yes, it's a product called ColorCoat Urban from Tata Steel (made in Wales):

Yes standard of the industry in northern New England. My house has brown enamel coated steel and has served well sense installed in 1987. The enamel has a few dings from ice sliding off from the valleys in the spring that need to be primed and painted and a full coat of paint could change the color and have it good for the next twenty years.

IIRC the PV installation is not grid connected, it is stand alone.
Probably very over sized under most conditions, but if enough power is to be produced under worst case conditions, then that is unavoidable.

Excuse me, if it was already mentioned somewhere in the replies, but is this way of building a house cheaper than when using not local and perhaps even non-sustainable materials?

I would like to live in exactly the same house one day like you, as I care about being in sync with the environment and local traditions, while at the same time have access to all modern gadgets.

Also, I checked your blog, hoping to see the progress you have made since April. Wonder how the construction looks like now? Do you already live in?

As this thread had drifted somewhat onto 3 phase electricity supplies, I have removed those posts that seemed to better fit into the electrical forum.

It's a good question. Our total build cost is around £750/sqm, but that looks higher than it needs to be as around half the building is double height (~6m) so we've got less internal floor area than we might have for a building this size. ie we could get around a third more floor area for relatively little extra cost.

This is around half the price of 'conventional' builds, BUT doesn't include 18 months of my labour (and a lot of other folk pitching in for free) to build the thing!

Some aspects of local or natural materials are cheaper (straw bale), but others (wood fibre insulation) are more expensive.

Won't be moving in until the spring.

Yes, with the system dimensioned for the winter, we have ~4 times more energy than we need in the summer. We'll have an immersion heater 'dump load' into a large ~300 litre thermal store but there'll still be occasions when there are literally several kW of potential electrical energy going 'spare'.
