An innovative idea to push for building retrofits.
Houses and building energy efficiency is a hot topic for me since I wrote my Master’s thesis on it back to 2006. Then I discovered that France had no less than 20 million buildings to insulate ( not bad for a country with 65 million inhabitants )
Now according to the Guardian, the UK Green Building Council wants to charge the owners of inefficient houses more and charge less the owners of efficient ones. This would be a great incentive to weatherize / retrofit your place.
As the article states, this would have to be coupled with sufficient helps to allow poor households to do the necessary work and / or change their boilers and heaters.
