When we started it, we took it from scratch. It was basically from scratch. It was five years. The long time was because of the consultation.
We don't sit down and close the door and say we'll do a code. Actually we were established under the commission for building and energy codes. They have to establish standing committees from different industry partners and government and so on to actually oversee the direction and development of the code, so it takes a longer time to do that and the consultation.
It took us five years to publish a document at that time, from 1992 to 1997. My guess is it will take a much shorter time now, because the work has been done. We had to start at that time from an energy code that was developed mostly from computer modelling, along with energy prices, construction prices, construction methods, and so on. I think that if we established a base, building it up again would, I assume, need a shorter time.
