Went to Build it Green convention and Expo today at the convention center downtown. A few good speakers, a lot of stuff I've already heard, mostly directed at developers. Didn't see too many architecture types out there. The first lecture was so-so. The second was interesting, more focused on green lab design, which is right up our alley. Its a shame we're really not incorporating any of the sustainable elements into this project. At least I'm getting better at understanding what we could do, and the technologies and techniques at the forefront of lab design.

Anyway, the third speaker was really good. A professor from Thunderbird School of Management, recently published in Harvard Business Journal, talking about the business side of sustainability. An odd lecture, he talked about the sweep of human history from hunter-gathers to agricultural societies to industrial, and the trade-offs we've made along the way. He used a stock portfolio analogy to describe the levels of productivity in these stages. Hunter-gathers, when the fish stocks are down, there are still deer to hunt = diversified. Agrarian states, which specialized in five grains, and three major animals to domesticate, specialized, and so stability was replaced by feasts followed by famine. Industrial societies specialized further, and so all the prehistoric knowledge of how to exist in the natural world diminished to practically nothing.

He made some other interesting points, but basically it came down to industry, in order to survive, must adopt the same rules which allowed the biosphere to exist since the advent of life on this planet. Namely, a radical simplification in the number of materials we use, which ties into his second rule, that everything must become cyclical, a value cycle instead of a value chain, where the consumer returns the product at the end of its commercial use to the producer who breaks it down and re-fabricates it. Lastly of course, is that these transformations must ultimately use solar power to do so. The lion dies and becomes food for the grass, the antelope eat the grass, the lions eat the antelope, etc. Circle of life as industrial model.

So that was fun. The expo was kind of slow. Mostly products for homeowners and developers. We got some silly putty, some recycled pencils and office supplies. And a green tote.
