Cob house development
https://www.bbc.com/news/articles/cxww982nkyko
2.0 kW/4.62 MWh pa in Ripples, 4.5 kWp W-facing pv, 9.5 kWh batt
30 solar thermal tubes, 2MWh pa in Stockport, plus Congleton and Kinlochbervie Hydros,
Most travel by bike, walking or bus/train. Veg, fruit - and Bees!

Re: Cob house development
The article is a bit light on any details to say the least!
3.87kWp PV
10.24kWp PV SolarEdge system
Tesla Powerwall 2
100 x 47mm Navitron tubes (still being installed!) Now likely to be removed for more PV.
MK2 PV router DHW diverter
Morso 5kW WBS
Vaillant AroTherm 10kW ASHP
Nissan Leaf

Re: Cob house development
Yes, but I was pleased to see that it will probably help self-builders get their plans approved a bit more easily.
Over the years I am sure we have seen lots of people stymied because they couldn't show how traditional techniques complied with rules drawn up for brick, concrete and steel.

Re: Cob house development
From what I can find it has an air source heatpump and an EV charger but no energy efficiency certificate yet. No sign of any solar panels or batteries.

EDIT - A bit more info on the building material here, but only says U value complies with building regulations,
https://www.bdonline.co.uk/opinion/cobb ... 46.article
"Experiments were completed to test the best composition of clay and fibre; with hemp and reed coming out top in terms of thermal insulation. The optimum thickness was calculated to be 300mm for both layers of lightweight earth and cob laid side by side. This combines excellent structural stability and a thermal ‘U’ value complying with Building Regulations, all tested in labs in the UK and France."

Re: Cob house development
I found another website which gives a U-value of 0.26W/m²k for the CobBauge.
https://www.building.co.uk/buildings/co ... 14.article
By comparison, Passivhaus standards are between 0.10 W/m2K to 0.15 W/m2K.
