Affordable, Sustainable Homes: Eco-Sense and the Future of Green Building


Here is link to the Cascadia report on Eco-Sense.  One year Research Project funded by a grant from Vancity and the Real Estate Foundation.  Gord and Ann have over 425 hours into this…250 of which was volunteer…we missed our summer.

Affordable, Sustainable Homes: Eco-Sense and the Future of Green Building  (Written for the public.)

Also a link to the Technical Report  which served as the basis for the Cascadia report.  Written by Gord Baird, Christina Goodvin of Goodvin Desgins, and Ann Baird.  Lots of graphs, tables, and building science analysis for the earthen walls in four seasons (temperature, humidity, dew point),  full technical analysis of sustainable energy systems (solar PV, Solar Thermal, wood gassification), full policy report, full water analysis (grey water, rain water harvesting, composting toilets, water balance tables, and more).

See research page on blog  for all the individual reports (water, solar PV, building code, wall performance, and energy comparison reports)

Energy Composition: Solar Thermal, solar PV and Wood


The latest data from the research and data loggers for the energy inputs.

Energy composition:  Solar PV, Solar thermal and Wood.  Solar thermal brings in a LOT more kWhrs than Solar PV.  The wood used so far this year translates into 1.26 cords of Douglas Fir.

Energy Composition for 6 months

In this graph, this documents the generated energy, not necessarily the energy used; the solar thermal gain in the summer time is partially used.  From this graph we can easily see that trapping and storing the solar thermal would have been a wise investment, possibly with the addition of another 30 tubes, we may not have needed the gassification boiler.  The $6500 put into the boiler could have gone into a large highly insulative storage medium, thus avoiding combustion.
