EcoBungalow Retrofit


35. Phew! What a scorcher!
I wrote in Blogpost 26 that I was looking forward to the next heatwave and seeing if I could manage overheating in the EcoBungalow better.

The short answer is: I feel it does better at keeping the house warm in winter than keeping it cool in summer.

32. EcoBungalow Retrofit: A Year's Worth of Energy
I can’t believe just how low my energy use has been for the first calendar year of living in the EcoBungalow. Perhaps I shouldn’t be quite so surprised. This project was meticulously prepared and executed, from buying the right sort of house through to getting a good architect on board and – most crucially – being constructed by a well-qualified builder with an eye for detail. But, even so, just ….. WOW! I’m using so much less energy for a house that is always pleasant to l
