sleep cycle and saving energy

Case Study: How two people (and legions of talented tradespeople) are building a new green home in British Columbia.

To date (Aug 11) we've spent $663,131. We've also saved $77,186 by doing tasks ourselves and scouring back alleys, thrift stores, landfills and Craigslist for free and cheap stuff. Included in that total are taxes saved by building before the HST, buying used, and doing our own labour ($37,012.)
