Amory Lovins of the Rocky Mountain Institute discusses energy building efficiency at a Stanford University seminar

June 1st, 2010 by Richard Lord

During his seminar Amory Lovins of the Rocky Mountain Institute says “Let’s start with my own house which is 2200 metres up in the Rocky Mountains where the lowest temperatures I have observed are -44 °C (-47 °F).  You can get frost any day of the year.  We have had it on the 4 July.  You can get 39 days of continuous mid-winter cloud, and yet if you come into the central atrium out of the snow storm there you are in the passive solar banana farm where so far we have harvested 28 banana crops, and then you realise that this building doesn’t have a heating system.

There’s no furnace because I didn’t need one and it was cheaper upfront not to put one in because it turned out that I could pay less for super insulation and super windows and air-to-air heat exchangers and got rid of the furnace than I would have paid just to install the furnace, let alone to run it.”
