By the end of Greenbuild, I was exhausted/troubled/elated with all sorts of conundrums swirling around in my head — not to mention a few partly written blogs, abandoned in favor of the next conversation... ... I had wanted to write about the 'executive roundtable' that happened that Wednesday — and responses to the twitter-submitted question "what single thing would have to change to make buildings actually regenerative?" (as in, way past 'less damaging' — past neutrality, even). I was encouraged to hear the execs express what I see as core issues (summarized and/or quoted below — no, I didn't record who said what):
- Waste and consumption is ridiculously cheap. If energy costs go up to the tune of $150/barrel for oil (or on-site renewables became radically cheaper), and/or if a cost is attached to emissions (not just air — also sewer and solid waste), we could get there.
- Our financial accounting systematically discounts the future. "We're trapped in a paradigm of net present value (NPV) — one of the worst tools known to man.... We need a new tool — 'Net Future Value'... and to start to reconceptualize buildings to see them as multigenerational assets."
- Corporations have to focus on shareholder's financial return above all else. Yes, the technology is there to do zero energy buildings but "for a profit making business with shareholders expecting a return they cannot generally be duplicated over and over."

You simplified PV to much. Inverters and panels can stop working so there is maintenance. Also you lose a lot of those electrons moving though...
