Interesting indeed Goldilocks. We have just started work to renovate our barn and have decided to go the energy saving route. We are currently having the roof insulated from the outside as this is more efficient, apparently, than just slapping panels of insulation under the beams. The sllates will then be put back and a full bank of PV panels fitted to generate up to 10,000 watts a year. Then we get the holes bashed out for the new windows and the walls will be insulated from the outside to a thickness of 6'/15cms. Underfloor insuation and heating follows with a heat exchange pump to drive that.
We won't have any energy bills in there apart from logs for a proper fire or log burner and we should have almost no electricity bills in the existing house part. Just continuing oil for the existing central heating installed 20 years ago. It's all going to cost more than we paid for the whol building 21 years ago but will be worth it.
Meanwhile, there are applications to surround our very windy village with over 80 monster wind turbines which are so cost ineffective, so intrusive on the environment and eye and so bad for migrating birds of which we have many, some rare, that I wonder just where politicians and finance ministers especially have their heads and hands.
