I’ve crunched my carbon footprint, and I’ve pondered other things that I might do, but most of all I’ve had quite a lot of fun learning. Maybe it’s my engineering mindset, but I’ve made a hobby out of conservation and meter watching, and had fun out of ‘tuning’ my life a little.
You’ll find the story of my renovation on my website. There’s a comprehensive costed list of improvements made plus a series of four articles covering my experience of aerogel insulation and solar PV, monitoring and continually improving the performance of my house    .

A few years ago I suddenly saw my energy bills as another performance metric that I could tweak. In fact, this whole area is full of numbers and graphs and science and gadgets and interesting techie puzzles. From aerogel and LEDs to iButtons and thermal imaging, you should see some of the fun I’ve been having!
1) My home and office electricity bill is about £190 per year on a premium all-green tariff. Gas is about £290 per year as of 2012, for me and my young family. I am saving over £1000 a year on my energy bills and I may be able to continue to cut waste faster than energy rates rise, so my bills could keep falling.
2) The living room is much warmer in winter (and cooler in summer) and less draughty and more comfortable. It’s the safe warm focus of the home.*
3) All these energy efficiency improvements have given us the opportunity to improve the decor and lighting more than we might otherwise have done.
4) The PV has also been excellent: maintenance free, taking us carbon neutral or negative for energy, and covering all our energy bills from FiT payments so effectively eliminating them.
* This was achieved by putting a door back in from the corridor, replacing the old and failing patio doors, adding thick curtains with solar reflective blackout blinds and installing aerogel dry lining.
