10% renewables

 

I have just received planning permission to rebuild my house (UK Surrey)
One of the conditions is to include renewable energy technology that will
provide 10% of the predicted energy use.
This was quite a surprise to me and I have no idea what it might imply..
Might it be as simple as a compost heap or will I have to build a wind farm
in the back garden?
Any pointers to where I might find more info would be appreciated

 



    The simplest, cheapest, most modular way to get something close to 10 %
renewable energy use is probably a solar hot water system.  With a bit of
thoughtful design, it could also be some south facing double glazed windows to
add some solar gain to your home.

Wow. Congratulations. I thought the usual UK planning permissions required
all houses to look like they were built 300 years ago :-) How about solar
heating with a clear corrugated polycarbonate (Dynaglas or Palram) steep
south roof or south siding?

With a small (5kW(t)) woodburning stove and the above I think you
could get better than 10% easily.

I've been experimenting blowing air up the inner leaf of a triple wall
polycarbonate sheet but I need a method to coat the bottom inner
surface with something matt black, as paint on the bottom outer
surface doesn't cut reflections. If it works my current plan is to
form a SW facing mansard roof out of this over 100mm polyisocyanurate
foam.
